The bio is a conversion page, 160 characters long
Every post that travels sends strangers to your profile, and the bio decides whether they follow. That's the whole funnel: post, profile, follow. Most founder bios fail it with vague ambition ("building the future of work") or a pile of pipes and emoji. The fix is boring and effective: what you're building, who it's for, one human detail.
Six bios, three bets
- Plain and credible: what + for whom, zero decoration. Works when your product name does the talking.
- Proof-led: built around a real number or milestone you gave it. Proof beats promise; the generator never fabricates it.
- Personality-led: the version people quote when they introduce you. Riskier, more memorable, best when your posts match the tone.
Make the whole profile agree
- Pick the bio that matches how you actually post, not how you wish you posted.
- Point your link somewhere that continues the sentence: your product, not a linktree of six options.
- Pin a post that proves the bio's claim. Bio says you ship fast? Pin the thread about shipping fast, built with the thread generator.
Questions
What should a founder's X bio actually say?
Three things, fast: what you're building, who it's for, and one thing that makes you a person. 160 characters is enough for all three if you skip the buzzwords. 'Building X for Y. Previously Z. I post about what breaks.' is a complete bio.
Should I put 'founder' in my bio?
Say what you're building rather than just the title. 'Founder' alone is a job title; 'Building Market or Die, AI agents that keep startup teams posting' tells people whether to follow you. The generator writes both shapes so you can compare.
Do keywords in the bio matter?
Yes, X search and follow recommendations read your bio. If you want to be found for 'AI agents' or 'SaaS', those words should appear naturally. Say what you do in the words your audience searches, not in metaphors.
Why six options?
Because the plain-credible version, the proof-led version and the personality version are different bets, and which one fits depends on your account. Two of each lets you pick a lane and still A/B in your head.
How many bios can I generate?
25 free runs a day per person, no signup, six bios per run. It never invents follower counts, revenue or anything else you didn't give it.
