When coaches research AI twin platforms, the biggest question is rarely about features or setup complexity. It is about money: do these platforms take a percentage of what I charge my subscribers, and how much will I actually keep?
The answer varies significantly between platforms. Some take a cut of every subscriber payment. Others charge a fixed licensing fee and let you keep everything above your operating costs. Understanding the difference determines whether your AI coaching business is genuinely profitable or just expensive to run.
We analyzed the current pricing structures of Delphi, Coachvox, and BuddyPro to show exactly what coaches keep after platform fees. The differences compound substantially as your subscriber base grows.
Do Delphi and Coachvox Take Revenue Share From Your Subscribers?
Yes, both platforms take a percentage of subscriber payments - but the amounts and structures differ.
Delphi charges a 15% revenue share on both their Builder ($79/month) and Scaler ($399/month) plans. On every subscriber payment processed through their system, Delphi keeps 15% and you receive 85%. This applies to all subscription revenue running through Delphi's checkout, which requires using a Delphi-connected Stripe Express account rather than your own Stripe integration. Their native checkout is also USD-only, per their documentation (docs.delphi.ai, checked August 21, 2026).
Coachvox takes a 10% platform fee plus 2.9% Stripe processing fees on every paid AI access transaction. Their software costs $83/month when billed annually ($996/year) or $99/month on monthly billing. One important detail: Coachvox's native AI access billing only supports weekly or monthly subscription intervals - not annual - which affects how you structure your pricing and cash flow. Their Coachcart product for digital courses does keep 100% (minus Stripe fees), but that does not apply to paid AI access, where the 10% fee still applies (coachvox.ai/charge-for-ai/ and support.coachvox.ai, checked August 21, 2026).
Both revenue share models mean your platform costs scale with your success. As subscriber revenue grows, the absolute dollar amount going to the platform grows with it.
What You Actually Keep: Real Numbers on $75,000 Annual Revenue
Here is the math that matters for a coach with 50 subscribers paying $1,500 per year each - $75,000 in total subscriber revenue.
With Delphi's 15% revenue share:
Platform cut: $11,250 per year
Your revenue after platform fee: $63,750
Plus software cost: $948-$4,788 per year depending on plan
With Coachvox's 10% fee structure:
Platform cut: $7,500 per year (10%)
Stripe processing fees: approximately $2,175 per year (2.9%)
Total platform fees: approximately $9,675 per year
Plus annual software cost: $996
With BuddyPro's fixed licensing model:
Platform revenue share: $0
Annual license cost: $2,364
AI usage costs (50 subscribers at $15-30/month each): approximately $9,000-18,000 per year
Your profit: approximately $54,636-63,636 (75-85% margins)
The difference between a 15% revenue share and a fixed licensing model compounds significantly as subscriber count grows. At higher revenue levels, the gap can reach tens of thousands of dollars annually.
Platform Cost Comparison: Delphi vs Coachvox vs BuddyPro
Platform | Monthly Cost | Revenue Share | Keep on $1,500/year subscriber* | Annual Billing for AI Access | Own Stripe Account |
Delphi Builder | $79 | 15% | $1,275 | Yes (via Delphi) | No (Express only) |
Delphi Scaler | $399 | 15% | $1,275 | Yes (via Delphi) | No (Express only) |
Coachvox | $83-99 | 10% + 2.9% Stripe | ~$1,306 | No (weekly/monthly only) | Yes |
BuddyPro | $197 | 0% | ~$1,140-1,320** | Yes | Yes |
*After platform revenue share only (not including software costs). **After AI usage costs of $15-30/month per subscriber; BuddyPro's $197/month license is a fixed cost shared across all subscribers.
How the Two Fee Models Affect Your Business as You Scale
Revenue share models create a dependency where your platform costs increase in direct proportion to your success. The platform profits alongside you, which keeps initial fixed costs low but compresses margins at scale.
Fixed licensing models like BuddyPro separate platform costs from subscriber revenue. You pay $197/month on annual billing regardless of how many subscribers you have or what you charge them. Your subscriber revenue, minus AI usage costs ($15-30/month per active subscriber), goes directly to your business. This is why top business coaching twins on BuddyPro reach 75-85% profit margins and generate $400,000+ annually.
The structural difference matters most at higher subscriber counts and higher price points. A coach charging $2,000/year with 100 subscribers ($200,000 revenue) would pay Delphi $30,000/year in revenue share alone. With a fixed licensing model, that same revenue produces dramatically different economics.
Annual billing is another practical consideration. Collecting $1,500 upfront rather than $125/month improves cash flow and reduces churn. Delphi supports annual billing through their checkout. Coachvox does not offer native annual AI access billing - subscribers pay weekly or monthly. BuddyPro supports annual billing through your own Stripe account, giving you full control over payment terms and customer relationships.
Payment account ownership also differs. Delphi routes payments through a Delphi-connected Stripe Express account, not your own Stripe. This limits your direct relationship with payment data and customer records. Coachvox and BuddyPro both allow you to use your own Stripe integration.
For more on building a sustainable recurring revenue model for coaches, the choice of billing structure matters as much as the platform itself.
Which Pricing Model Makes More Sense for Your Coaching Business?
Revenue share platforms make more sense when you are testing demand with lower subscription prices or when you prefer lower upfront platform costs. If you charge $50-100/month per subscriber, a 10-15% fee feels manageable and reduces the financial risk of launching.
Fixed licensing models become decisively more profitable at the $1,000-2,000/year price point that most successful AI coaching twins target. At $1,500/year with 50 subscribers, the revenue share model costs you $9,000-11,250 more annually than a fixed license - before software fees. That gap grows with every additional subscriber.
Most coaches who build at the premium end - charging $1,500-2,000/year for an AI mentor that provides personalized, relationship-based guidance - find that the zero-revenue-share structure produces substantially better unit economics. The platform that already has 150+ AI twins launched and $5M in total subscription revenue processed reflects this pattern.

The Costs That Do Not Appear in the Platform Pricing Page
Platform fees and revenue share are only part of your total cost structure. Customer acquisition - typically 20-40% of revenue depending on your channel mix - is often the largest expense, and it applies regardless of which platform you use.
AI usage costs vary by platform and engagement level. On BuddyPro, these run approximately $15-30/month per active subscriber and reflect actual LLM compute - they scale with how much subscribers use the twin, not just subscriber count. Revenue share platforms may absorb AI costs differently, but those costs are ultimately factored into what they charge you.
Payment processing adds another layer on revenue share platforms. Coachvox's 10% fee is on top of Stripe's standard 2.9% - so on a $125/month subscriber payment, you are paying close to 13% total before software costs. On Delphi, the 15% fee goes to them via their Stripe Express setup, and your standard Stripe processing fees are included in that structure.
For a detailed breakdown of how Coachvox's full fee structure works across their plans, see our full Coachvox pricing breakdown. Understanding total cost of ownership - not just the headline percentage - is what separates a profitable AI coaching subscription from one that looks good on paper but underperforms in practice.
The expert who launches a premium AI twin first in their niche sets the price anchor and captures the audience before competitors enter. Platform economics determine how much of that revenue you actually keep long-term. Choose accordingly.
