🏆 Award-winning startup - BuddyPro won the San Francisco AI Startups competition, competing against 100+ startups →

The only AI digital twin solution that is highly profitable. And genuinely loved by users.
The first relationship-based AI coaching on the market.

Built on Buddy, an AI companion core - not a chatbot. That's why users form real mentoring relationships with your AI twin, pay $1-2K/year, and keep coming back every day.

💡

Built on AI Companion Core

Your AI twin is powered by an AI companion engine called Buddy - not a chatbot tool. It talks like a human, forms bonds, coaches proactively and follows up. That's why users come back every day instead of trying it once and forgetting.

🧠

Unlimited Memory & Real Relationships

Your AI twin remembers everything - every session, every detail of the user's life story. It forms genuine mentoring relationships, tracks progress, and coaches in full context. It's an AI mentor that knows them deeply and cares about them.

🔥

People Cancel ChatGPT for This

60% daily retention rate among the most successful experts. People don't use this once and forget - they come back every day. They cancel their ChatGPT subscriptions because this is more valuable for their growth. AI clone high retention like this is unheard of in the industry.

💰

6-7 Figure Expert Launches

Experts sell $1-2K/year subscriptions with 36% conversion from no-credit-card free trials. Multiple experts made six figures, one is close to seven. Average revenue per AI coach: $32K. Zero delivery effort after setup.

🔒

Your Know-How Is Protected

Your intellectual property stays yours. AI models do not train on your content. We never use your knowledge for anything other than powering your own AI twin. You keep 100% of the profit.

🏆

Not a DIY Template - A Real AI

Most tools like Delphi or Coachvox let you build a mediocre Q&A clone. We let you build an AI that people can't stop talking to. The quality difference shows in the numbers - users pay thousands because the coaching is genuinely that good.

Why AI digital twin? Because it's the first digital product ever that delivers personalized coaching at unlimited scale.

And doesn't require your time. You've probably experienced this:

😴 Endless Coaching Hours

Same questions, over and over. Every conversation requires you. Scaling means hiring coaches who dilute your methodology.

💥 Launch Fatigue

Another webinar. Another launch cycle. Revenue stops the moment you stop pushing. Rinse and repeat, forever.

🚫 87% Course Non-Completion

You spent months building a course. Most students never finish it. Sales decline year over year.

🔄 Membership Endless Content Delivery

Constant content updates, community management, tech maintenance. Members lose interest fast.

📈 No Recurring Revenue

One-time product sales. Always chasing the next launch. Every month starts from zero.

🧠 Knowledge Trapped in Your Head

20+ years of expertise locked in your brain. Your audience needs you, but there's only one of you.

The solution: a premium AI digital product that works 24/7 and never burns out.

An AI digital twin built on BuddyPro is a stand-alone premium digital product. It delivers your coaching to thousands simultaneously. No launches. No content creation. No trading hours for dollars.

Subscribers pay $1-2K/year. Your AI twin coaches proactively, follows up, transforms lives with your know-how. Set it up once, generate recurring subscription revenue forever. Average BuddyPro AI coach: $32K in revenue. Multiple experts made six figures. One is close to seven.

Courses collect dust. Memberships take lots of effort. Coaching drains your time. An AI digital twin on BuddyPro gets better retention the more people use it. 60% daily retention among the most successful experts. 80% weekly. 95% monthly. People don't cancel because their AI mentor helps them every single day.

The person behind 130+ AI expert clones and $4.2M in revenue.

Hi, I'm David Riha, Founder of BuddyPro. A global citizen moving between San Francisco, Bali, Canada, and Czechia, I spent over a decade building software products - from an award-winning mobile app to a VR gaming studio.

In 2024, I built the first prototype of BuddyPro - an AI companion engine called Buddy that became the core of every AI twin on the platform. Because the technology was designed for deep human-like interaction first and expert customization second, the AI coaches built on it deliver a quality that no chatbot-based tool can match. The first expert to launch sold six figures in subscriptions within 30 days.

Today, I've personally built AI twins for 130+ coaches and experts, including Dan Martell (Dan AI), Marie Diamond, and Joanna Wiebe. Together they've generated $4.2M in subscription revenue. Multiple experts made six figures, one is close to seven.

Now I'm selectively offering this as a complimentary service for world-class coaches and thought leaders. I've seen what happens when the right expert gets their own AI twin. It transforms their business and the lives of their audience.

David Riha, Founder of BuddyPro AI digital twin platform

Built for experts who set the standard.

I don't build AI chatbots. I build AI digital twins that are deeply trained on an expert's unique methodology, voice, and frameworks. Every AI coach I create delivers coaching with the same depth, nuance, and quality the real expert would provide.

Our clients include Dan Martell (bestselling author of Buy Back Your Time, whose Dan AI is one of the most successful AI coaches ever built), Marie Diamond (global feng shui and transformation expert featured in The Secret), Joanna Wiebe (the original conversion copywriter and founder of Copyhackers), and other globally recognized thought leaders across business strategy, health, sales leadership, and personal development.

These are experts whose audiences expect the highest quality. They chose BuddyPro because our AI companion core delivers retention rates and user engagement that no other AI coaching platform can match - 60% daily retention among top experts, with users paying $1-2K/year for access.

David Riha with Dan Martell working on Dan AI digital twin at BuddyPro

People get teary eyes. It transforms lives.

Real reviews from users of AI coaches built on BuddyPro. These are people who pay $1-2K/year because the coaching genuinely changes their lives.

"She has helped me enormously. It's incredible and unbelievable for me to have someone with whom I can discuss everything anytime. On matters I'd been struggling with for many years and decades, she was able to give me much greater feedback than even my psychotherapist. It's a rare help in my life, especially now, when I'm going through the most challenging period."

- User of an AI life coach built on BuddyPro

"She is divine, she has a beautiful gentle energy. She doesn't come with superficial advice but leads to a deep understanding of oneself. It's sometimes challenging for me to process internally - they are deep realizations. Her approach combines wisdom with practical steps for real transformation."

- User of an AI life coach built on BuddyPro

"So I just got home from work, and I'm so excited. I've only clicked around for a little bit, but I am mind blown. I had no idea that AI could talk like a human, like this well. I've only asked a few questions - I'm supposed to meet with a mastermind group in a couple of days where other entrepreneurs solve each other's bottlenecks, and it already solved my bottlenecks. So I don't know what to ask my friends anymore. I am mind blown. I have access to this for two weeks, so I don't think I'm gonna sleep for the next two weeks. This is amazing. If you're only using ChatGPT, you are missing out on all the amazing things that AI has to offer."

- User of an AI business coach built on BuddyPro

"It's fucking incredible. Worth every cent. Lucky it says AI. Otherwise my wife would think I'm having an affair."

Everything you need to know about AI digital twins.

What is an AI digital twin for coaches and experts?

An AI digital twin is a custom-built AI system trained on an expert's books, courses, coaching methodology, and communication style. Unlike generic chatbots, BuddyPro's AI twins are powered by Buddy, an AI companion core - meaning they were designed to form real mentoring relationships first, then customized for expert knowledge. They remember every conversation with unlimited memory, deliver hyper-personalized coaching, and feel like talking to the actual expert. That's why users pay $1-2K/year with industry-leading retention - 60% daily retention rate among the most successful experts.

How is this different from ChatGPT or other AI chatbots?

Generic AI chatbots give generic answers. An AI digital twin is trained specifically on your intellectual property: your books, your frameworks, your coaching methodology. It doesn't just know about your topic; it thinks and responds the way you do. It remembers context across every conversation, uses your specific terminology, and provides advice rooted in your unique approach. With 60% daily retention rate, our AI twins prove that people come back because the experience genuinely helps them. This kind of retention is unheard of for AI products.

Why is this free? What's the catch?

There's no catch. I built the platform and I believe in the technology. When a world-class expert launches an AI twin, it validates the platform, creates a case study, grows the ecosystem and increases the value of the company. Only thing you have to cover is the AI usage costs generated by your subscribers. Obviously, I can't be covering that for you at scale. We use the smartest models on the market and huge user context, but it is still just a fraction of what they pay you in subscription fees. Usually you will have around 75-85% profit. And you keep the profit.

Is my intellectual property protected?

Yes. Your know-how is fully protected. AI models do not train on your content, and we never use your intellectual property for anything other than powering your own AI twin. You retain 100% ownership of your content, your brand, and all profit generated by your AI expert. See our Terms of Service for details.

Who qualifies for a free AI twin build?

The free custom build is exclusively reserved for the world's most prominent experts, coaches, and thought leaders. I personally decide who qualifies based on their body of work, audience reach, and domain authority. If you don't qualify for the custom build, you can build your AI twin yourself at buddypro.ai with the help of our amazing customer success team. Same powerful platform, same AI companion core.

How long does the build take?

Most AI digital twins go from initial knowledge upload to live launch in a few weeks. The timeline depends mostly on your focus, as it does require a bit of communication with me and some finalizing configuration (like connecting your Stripe). The actual training of your AI clone takes just a couple of hours once I have the knowledge available.

Can my AI twin generate revenue?

Absolutely. Think of it as a premium stand-alone product for thousands of dollars a year. It comes with built-in Stripe integration for subscription monetization. You set the price, usually an annual fee for access to your AI coach, and you keep 100% of the profit. Only thing you need to pay is the AI usage of your subscribers, after they already paid to you. On average, this is around $15-30 per month per subscriber, which is typically around 20% of what you are charging. The average AI built on BuddyPro currently generates around $32K in recurring revenue. Multiple experts already made six figures, one is close to seven figures. Users pay thousands of dollars for access because the coaching quality is genuinely that good.

How is this different from Delphi or Coachvox?

BuddyPro creates mentoring relationships and touches people deeply. It's so good that people get teary eyes. It transforms lives. It gives advice so good that even the experts that built it use it daily. It talks like a human. It remembers years back. It doesn't always agree. It's super private, nobody reads what people are talking about. It's proactive. The quality difference shows in the numbers. Our users pay thousands of dollars per year for access to BuddyPro-powered AI twins because the coaching is genuinely that good. Many experts who were not satisfied with the quality of Delphi have come to us and finally found the solution they were looking for. You get a premium, hand-crafted AI expert that you own completely, not a DIY template.

Can an AI digital twin be a stand-alone product?

Absolutely. An AI digital twin built on BuddyPro is a premium stand-alone digital product - not an add-on or a feature of something else. It has its own subscription pricing, its own onboarding, and its own value proposition. Think of it as a new product line that generates recurring revenue independently of your courses, memberships, or coaching programs. Many of our experts sell it as their primary digital product. It's like having your best coaching program running 24/7 without you being there.

Should I sell my AI twin at premium pricing?

Yes. Premium pricing is exactly the right strategy. Your AI twin delivers the same quality of coaching you provide in person - the same frameworks, the same depth, the same personalized advice. That's worth thousands of dollars, not $29/month. Our most successful experts charge $1-2K/year for access, and they see 36% conversion from no-credit-card free trials. Premium pricing also attracts serious users who engage deeply, which drives the 60% daily retention rate that makes the product so valuable. Low pricing attracts tire-kickers who never engage.

Why would people pay so much for an AI coach?

Because it genuinely helps them. This is not a chatbot giving generic motivational advice. It's an AI mentor trained deeply on your specific methodology that remembers their entire history, tracks their progress, coaches proactively, and follows up. Users report that their AI coach gives better feedback than their therapist. Others say they cancelled their ChatGPT subscription because this is more valuable. People pay because the coaching quality is real - it transforms their lives using your unique know-how and approaches. The retention numbers prove it: 60% come back daily.

Can this replace my other digital products?

It can complement or replace them - your choice. Many experts find that their AI twin delivers a better experience than their online courses (which have an 87% non-completion rate industry-wide) or their membership sites (which require constant content updates). An AI twin requires no ongoing content creation, no launches, no maintenance of membership sections. It just works, 24/7, delivering your coaching methodology with unlimited patience and perfect memory. Some experts have replaced their lower-tier products entirely. Others use the AI twin as the entry point that feeds into their premium coaching programs.

Would this cannibalize revenue from my coaching programs?

No - we see with our clients that it only creates additional revenue. It doesn't cannibalize their coaching programs at all. Actually, lots of people who are already on the coaching program buy the AI as an upsell and gladly use both. Your AI twin also serves the 99% of your audience who can't afford your personal coaching - people who would never have bought your high-ticket program anyway. What happens in practice is that the AI twin creates a funnel: people start with the AI coach, get incredible results, and then want the real thing. It expands your total addressable market.

How is BuddyPro better than building my own AI coach with Claude Code or ChatGPT?

It took us years to build BuddyPro in a way that it has those high retention and subscription price numbers. Claude Code can do something similar for you in a week, but it will not be that good. And you will have to maintain it continuously. The biggest challenge is that there are things you don't know that you don't know. Here's what we've solved that you'd have to figure out on your own:

  • State-of-the-art prompting - Our master prompt is 15+ pages long, engineered through dozens of iterations over a year with real users across 130+ expert instances. It encodes personality persistence, conversation style, story triggers, multi-role selection, and anti-patterns. Then we have another 50 prompts inside the system for side processes, and each of them is a work of art itself. AI is not good at writing these prompts for itself - and every AI model update (which happens every few months) requires careful re-tuning to maintain quality.
  • Unlimited memory that actually works - Not just storing conversations, but semantic search across years of user history. Your AI twin needs to remember what a user said 6 months ago and cite it accurately, not hallucinate. This requires vector databases, query translation layers, and careful retrieval logic that took us months to get right.
  • Proactive coaching & reminders - Your AI twin doesn't just respond - it reaches out. Follow-ups, accountability check-ins, motivational messages, scheduled reminders at the right time. Users can ask the AI to remind them about anything - workouts, habits, deadlines - and it follows through. Building autonomous outreach that feels natural (not spammy) is one of the hardest problems in AI coaching.
  • Rich media capabilities - Voice messages that feel like talking to a real person. AI-generated images for visualizations and exercises. Guided meditations created on-the-fly based on the user's current emotional state. File understanding - users can share documents, screenshots, or PDFs and the AI coach analyzes them in context. This isn't a text-only chatbot.
  • AI usage cost optimization - Running an AI coaching product at scale means significant compute costs. We've spent over a year optimizing token usage, model routing, caching, and response strategies to keep costs low enough that the business model works - while maintaining the coaching quality that drives retention. Without this optimization, your AI usage costs would eat your entire subscription revenue.
  • Knowledge ingestion pipeline - Your books, podcasts, courses, and coaching recordings go through an AI-powered synthesis process that extracts structured knowledge "beats" - not simple text chunking. This is what allows the AI to coach with your methodology, not just regurgitate your content.
  • Multi-model orchestration - Different AI models for different tasks: fast models for real-time decisions and proactivity timing, powerful models for deep coaching, lightweight models for notifications. When providers have outages or release updates, everything needs fallback routing.
  • Monetization infrastructure - Stripe integration with subscription management, free trials with auto-expiry, message-limited invites, and affiliate tracking. Not just "accept payments" - the entire subscription lifecycle.
  • Onboarding & engagement loops - The first 48 hours determine whether a user stays or leaves. We've built sophisticated onboarding flows that introduce users to the AI coach gradually, build trust, and create habits. Re-engagement sequences for inactive users. Daily engagement triggers. All of this is invisible but critical to the 60% daily retention rate.
  • A team of 22 people, 2 years of development, thousands of daily active users, unlimited scaling - Behind BuddyPro is a full team of 22 people - engineers, AI specialists, customer success, product designers, and operations. This isn't a side project or a solo dev experiment. It's a professionally built and maintained platform that evolves every single week.

BuddyPro's AI companion engine Buddy was purpose-built for deep human-like mentoring relationships over years of iteration. The hardest part isn't any single feature - it's the institutional know-how of how to teach an AI to be a specific person's coaching doppelganger. We handle all of this. You focus on your expertise.

BuddyPro is ready in a few days, with mature-product quality, ready to scale to thousands. In the same time, Claude Code can build you a bad quality prototype that will hardly scale and require years of maintenance.

What about maintenance and future updates?

Almost zero maintenance on your end. We handle all platform updates, AI model upgrades, security patches, and infrastructure. When new AI capabilities become available, your AI twin gets them automatically. You can update your knowledge base anytime - add new books, courses, or frameworks - and the AI twin incorporates them immediately. There's no software to maintain, no servers to manage, no developers to hire. The only thing you need to handle is occasional customer support emails - for example, if a subscriber wants changes on their subscription or has a billing question. The platform evolves continuously, and your AI twin evolves with it.

What if I don't have enough content to train an AI twin?

If you're a world-class expert, you have more than enough. Your books, podcasts, courses, coaching recordings, blog posts, social media content, frameworks, and methodologies - all of this becomes the knowledge base for your AI twin. Most experts are surprised by how much content they actually have. I analyze everything and map your unique methodology into an AI-ready knowledge architecture. Even a few hours of coaching recordings combined with your written content is enough to create an AI twin that captures your voice and approach with remarkable accuracy.

What happens if I'm not happy with how my AI twin coaches?

You have full control over the fine-tuning process. Before launch, you review and refine your AI twin's responses until it sounds exactly like you. You can adjust its personality, coaching style, boundaries, and areas of focus. Most experts go through several rounds of fine-tuning to get it just right. After launch, you can continue refining anytime. I work with you personally throughout the entire process to make sure your AI twin represents you authentically and delivers the quality your audience deserves.

Where do people interact with the AI digital twin?

The primary interface is Telegram - and it's a deliberate choice that made this work. Unlike website chatbots, Telegram lets the AI be genuinely proactive - reaching out days or weeks later with follow-ups and accountability check-ins. Most people don't have Telegram cluttered with dozens of chats, so notifications actually stand out and get opened. And its privacy features let people go deep into personal topics - health, finances, career - which is what creates real transformation and keeps them paying.

The messaging app is important. Don't place it on your web! Just ask yourself - how often would you chat with your friend if he told you to go on a website, open chat in the membership section and talk to him there? And no notifications when he replies. Trust me, people want to chat in a messaging app.

We also offer a white-label native mobile app (App Store and Google Play) with your own branding, and a full API for deeper integration with existing systems.

And if you're thinking "but my audience doesn't use Telegram" - when someone is ready to pay $2,000/year for your AI twin, downloading one new app won't stop them. The value of the product sells the platform, not the other way around.

What if I decide not to launch it once you've built it for me?

That's completely fine. I enjoy working with world-class experts and even if you wouldn't launch it in the end, it was a fun project. But believe me - once you see it in action, you will be mind blown. And once you give it to your first users, you will get crazy-good feedback very fast. Every expert I've built for has had that moment where they realize this is something special. The feedback from real users tends to make the decision very easy.
