"shortDescription": "Feedback on pitches and calls",
"longDescription": "FounderBrain gives you feedback on how you came across in a meeting, and coaching on what to try next time. Share the transcript of a fundraising pitch, VC or investor call, sales call, interview or practice run, exported from your meeting or transcription tool with speaker labels, then say which speaker is you, and FounderBrain compares how you spoke with 773 public interviews of founders and CEOs.\n\nThe report shows where you sit on four speaking styles (calm or enthusiastic, open or private, careful or certain, data or stories), your speaking type, the well-known founder or investor you sound most like, the habits that stood out (such as saying a lot more than was asked) and what to try next time, and you receive practical coaching supported by quotes from the meeting. The full visual report appears in the conversation.\n\nWith the same prepared transcript and speaker settings, scoring is repeatable, and an analysis needs at least 300 words from the speaker. FounderBrain needs no account. FounderBrain deletes the received transcript when the analysis finishes and does not retain it or use it for training. Your AI app handles the conversation under its own terms.",
