Every coach who gets serious about building their AI twin eventually hits the same calculation: after paying for the platform and giving up a cut of their revenue, what do they actually keep?
The pricing page shows you one number. The revenue math tells you a very different one. And when you are trying to build a business generating six figures from AI coaching subscriptions, that difference is not trivial.
Here is an honest breakdown of how Delphi and Coachvox actually work on the financial side - what each platform costs, what they take from your subscriber payments, and what ends up in your account after your first 100 subscribers. Then I will explain why the margin math alone is only half the picture.
Delphi Pricing in 2026: Plans, Revenue Share, and the Full Cost
Delphi offers three tiers (per Delphi's public pricing page, checked August 30, 2026).
The Free Plan is $0/month. It includes 1 million training words, voice calling and chat, support for 40+ languages, a basic CRM with up to 100 contacts, and unlimited chats. Enough to explore the concept - not enough to build a real commercial AI coaching product.
The Builder Plan is $79/month on annual billing ($948/year). You get 5 million training words, YouTube and podcast training support, an analytics dashboard, Slack integration, and 2 embedding locations for placing your AI.
The Scaler Plan is $299/month on annual billing ($3,588/year). This is where monetization features live at scale - 12 million training words, custom domain, custom branding, 10,000 contacts, and 10 embedding locations.
Here is the piece that most evaluation articles gloss over: Delphi takes 15% of every subscription dollar your AI twin generates.
I have a full breakdown in my Delphi pricing deep dive, but the practical math is this: if you have 100 subscribers each paying $2,000 per year, your gross revenue is $200,000. Delphi takes $30,000 of that. Add the Scaler plan at $3,588 per year, and your platform costs reach $33,588 before you have counted Stripe fees.
There is also a structural detail worth knowing: Delphi processes your payments through a Stripe Express connected account they set up on your behalf. You cannot connect your own existing Stripe account. That means Delphi sits in the middle of your payment relationship with subscribers by design.
Coachvox Pricing in 2026: Flat Fee, No Revenue Share
Coachvox takes a much simpler approach. A 14-day free trial, then one plan: $29/month on annual billing ($348/year) (per Coachvox's public pricing page, checked August 30, 2026).
The Pro Plan includes unlimited AI conversations, unlimited clients, advanced customization and training options, priority support, and detailed analytics reporting.
The critical difference from Delphi: Coachvox takes zero revenue share. You keep 100% of what subscribers pay - minus Stripe's standard processing fee of 2.9% plus $0.30 per transaction. You connect your own Stripe account directly.
On that same $200,000 in annual revenue from 100 subscribers:
- Coachvox platform: $348/year
- Stripe fees: approximately $5,830
- Total platform costs: around $6,178
- Net to you: roughly $193,822
Compare that to the Delphi Scaler scenario: $33,588 in platform costs on the same revenue, leaving you with roughly $166,000. Coachvox comes out $27,000 ahead on identical revenue numbers.
On paper, Coachvox wins this comparison by a wide margin. But there is a critical assumption baked into that math.
The Number That Actually Determines Which Platform Wins
The margin comparison only holds if you are charging the same subscription price on both platforms. In practice, you are not - and that changes everything.
Here is the table first, then the explanation behind it.
| Feature | Delphi | Coachvox | BuddyPro |
|---|---|---|---|
| Platform cost (annual billing) | $79-299/mo | $29/mo | $197/mo |
| Revenue share | 15% of subscriber revenue | None | None |
| Payment processing | Delphi's Stripe Express (cannot use own) | Your own Stripe account | Your own Stripe account |
| Free trial | Free plan available | 14-day free trial | Application-only |
| Long-term memory | Not publicly disclosed | Not publicly disclosed | Unlimited across all conversations |
| Net margin on $2K/year at 100 subscribers | ~83% (after 15% share + Scaler plan + Stripe) | ~97% (after Stripe only) | 75-85% (after AI usage + platform) |
| Verified typical subscription price | Not independently verified | Not independently verified | $1,000-2,000/year |
Coachvox's 97% margin looks extraordinary. But that calculation assumes your subscribers are paying $2,000 per year. Whether users will actually pay $2,000 per year for an AI coaching product - and keep paying it the following year - is entirely determined by how good the experience is.
Coaches I have watched try to charge $1,500-$2,000 per year on platforms built for low-cost infrastructure run into the same problem. The AI gives solid answers to explicit questions. But it does not remember what the subscriber was struggling with three months ago. It does not proactively follow up when it notices a pattern. It does not coach with the kind of depth and continuity that makes someone feel genuinely understood over time.
Users figure this out within a few weeks. The renewals reflect it.
A 97% margin on $29/month subscriptions is $28 in your pocket per subscriber per month. A 75% margin on $2,000/year subscriptions is $1,500 per subscriber per year. Those are not the same business - they are not even close to the same business.
What Drives Premium AI Coaching Pricing - And Where BuddyPro Fits
The experts building on BuddyPro who charge $1,500-$2,000 per year and see strong annual renewal rates share a common thread. Their AI remembers. Not just the most recent conversation - but what a subscriber shared six months ago, what goals they set four weeks back, what they were struggling with last week. The AI connects those dots and coaches in full context, every single time.
That relationship-based coaching is what drives daily return rates and annual renewals. Without it, you have a sophisticated FAQ tool. Users know the difference, and they vote with their wallets at renewal time.
BuddyPro was built for this specific use case. It runs on frontier AI models with unlimited long-term memory, designed from day one to form real mentoring relationships rather than answer isolated queries. The technology behind building an AI coach at that level of depth is why the cost structure is different from lighter-weight alternatives.
The numbers: $197/month for the platform ($2,364/year), plus the AI usage your subscribers generate - typically $15-30 per subscriber per month. With 100 subscribers at an average of $20/month in AI usage, that is about $24,000 per year in AI costs. On $200,000 in gross revenue, your net comes to roughly $173,600 - around 87% margins with no revenue share.
No cut to the platform. Your Stripe account. Your subscriber relationship. Your profit.
The platform cost is higher than Coachvox. But it is designed for a subscription price tier where the AI is genuinely worth $2,000 per year - where users cancel their ChatGPT subscriptions because this is more valuable, and where the retention numbers (60% daily return rate among the most successful experts on the platform) reflect that the product earns its price point every single day.
Multiple experts building on BuddyPro have crossed six figures in recurring revenue, some approaching seven figures. That is not a margin story. It is a product quality story that changes the entire revenue equation.
Which Platform Is Right for You?
If your audience is unlikely to pay more than $50-100 per month for an AI coaching experience, and you want to maximize margins on lower-priced subscriptions, Coachvox's flat $29/month with zero revenue share is the most financially efficient option.
If you are already on Delphi and looking at the revenue share math: the 15% starts to sting at meaningful scale. On $100,000 in subscription revenue, you are sending $15,000 to Delphi before platform fees. On $500,000, that is $75,000 - plus the Scaler plan at $3,588/year for custom branding. These costs grow directly with your success.
If you have real expertise, an established audience that trusts you, and you want to build something people pay $1,500-$2,000 per year for because it genuinely transforms how they think, act, and perform - that is the market BuddyPro is built for. The per-subscriber AI cost is real, but it is offset by the subscription price you can sustainably charge and the renewal rates that follow from users who get actual results.
The right platform is not the one with the lowest take rate. It is the one where the AI is good enough that your subscribers do not want to cancel.
