What you get
- Your speaking type
- One of five speaking types found across 773 founder interviews, such as The Open Enthusiast. If you were close to a second speaking type, it says which.
- Four styles

- Who you sound like
- The well-known founders and CEOs whose public interviews are closest to yours, and the one least like you.
- Habits that stand out
- Things you do much more or much less often than most founders, such as putting dates on things or qualifying your claims.

Things to ask Claude
How it works
- FounderBrain splits the chosen speaker's answers into short passages.
- A small language model on FounderBrain's own server answers 100 fixed yes or no questions about each passage, such as whether it backs a point with a specific figure, like revenue or growth, or tells a story from experience.
- A statistical model from psychometrics turns those answers into the four styles, compared with 773 public interviews of 266 guests of Lenny's Podcast, 343 of Mixergy and 164 well-known founders and CEOs.
The same transcript always gives the same result. Neither end of a scale is better, and the result describes one conversation, not a personality. FounderBrain is meant for coaching, not for predicting success.
FounderBrain is the first pre-trained model built with Think, Reason, Learn, Vela's open-source library.
Your transcript is not stored
Claude sends the transcript to FounderBrain's server when it runs an analysis. The server scores it and deletes it as soon as the analysis finishes. It keeps no transcript or report, and nothing you send is used to train a model.
- Only the speaker you choose is analysed.
- Our logs are designed to hold word counts, timings and errors, never text or names.
- Your Claude conversation is kept by Anthropic under its own terms.
The privacy policy has the details.
If an analysis does not work
A transcript needs one speaker turn per line, like this.
Ana: We started the company after running a freight yard.
Tom: How did you find your first customers?Claude can reformat most exports from Zoom, Meet, Teams, Otter or caption files if you ask it to. FounderBrain needs at least 300 words from you and works best with a few thousand, and a transcript can be up to 15,000 words.
If FounderBrain says it is busy, the hourly limit has been reached, so try again a little later.
Questions and problems go to support@thinkreasonlearn.com. Please say what you asked Claude and when. There's no need to send the transcript.
Security reports go to security@thinkreasonlearn.com.
Frequently asked questions
Is FounderBrain free?
Yes. FounderBrain is free and needs no account. There is an hourly limit on analyses so that the service stays available for everyone.
Does FounderBrain store my transcript?
No. The transcript is scored on FounderBrain's server and deleted as soon as the analysis finishes, and nothing you send is used to train a model. Your Claude conversation is kept by Anthropic under its own terms.
How is it different from asking Claude for feedback on my pitch?
Claude on its own gives an opinion. FounderBrain measures your answers against 773 public founder interviews with a fixed model, so the same transcript always gets the same result, and Claude then coaches you from those measurements.
Which meetings work best?
Pitches, investor calls, sales calls and interviews where you answer questions, with at least a few thousand words from you. It works with transcripts from Zoom, Google Meet, Teams, Otter, Granola and most other tools.
