Startups Must Pick One AI Platform
by Brian Balfour on August 17, 2025
The emergence of ChatGPT as a new distribution platform represents a rare growth opportunity that follows predictable platform cycles.
The Four-Step Platform Cycle
Every new distribution platform follows the same pattern:
-
Step 0: Market Conditions
- Consensus emerges about a new category (social, mobile, AI)
- 5-7 major players battle with no clear winner yet
- Fierce competition as stakes are high (markets typically end in monopolies or duopolies)
-
Step 1: Identifying the Moat
- A player identifies their defensibility mechanism
- They press their advantage to gather that moat as quickly as possible
- They need an ecosystem to help build this moat, so they open a platform
-
Step 2: Platform Opening
- Company establishes a third-party platform with incentives
- The value exchange: developers build on the platform, adding use cases and engagement
- In return, developers get distribution for their applications
-
Step 3: Platform Closing
- Eventually, platforms lock down for monetization and control
- They either shut down third-party access, develop first-party alternatives, or suppress organic distribution to push paid mechanisms
- By this point, the platform has built enough defensibility that they can afford to close
Why ChatGPT Will Likely Be the Next Major Distribution Platform
- ChatGPT has identified the key moat: context and memory
- Their retention curves show significantly higher engagement than competitors
- They're already hiring for roles related to a third-party "agent platform"
- They're forming preferred partnerships with major companies (like HubSpot)
- They have 10x more monthly active users than competitors like Claude
How to Play the Platform Game
For Late-Stage Companies:
- You can afford to place multiple bets across platforms
- Wait to see which platform emerges as the winner, then concentrate resources
- Risk: waiting too long can leave you behind competitors
For Early-Stage Startups:
- You must choose one platform and go all-in
- You have scarce resources and attention - can't afford to spread too thin
- Higher risk but higher potential reward
How to Choose Which Platform to Bet On
- Prioritize retention and engagement depth over vanity metrics like MAUs
- Evaluate user quality and monetization potential (like iOS vs Android)
- Analyze the value exchange - what are they giving you to incentivize development?
- Consider scale - but remember that better retention beats larger distribution
The Prisoner's Dilemma of Platform Adoption
- Many companies hesitate to integrate with new platforms, fearing loss of control
- But there is no opting out - if you don't participate, your competitors will
- Customer expectations will shift to include these new experiences
- The cycles are getting shorter, giving you less time to capitalize
Planning Your Exit Strategy
- As soon as you enter the game, start planning your exit
- Build ways to own important parts of the user experience
- Accumulate specialized data and context the platforms don't have
- Create micro-network effects that persist beyond the platform
The opportunity window is likely to open within the next six months, with ChatGPT expected to launch a third-party platform that will create a new distribution channel for those ready to capitalize on it.
