He quit his job, went all-in on AI agents—then grew to 100K users & a $30M Series A in a year. | Soham Ganatra, Founder of Composio

A Product Market Fit Show | Startup Podcast for Founders

Soham spent 6 months building AI that would auto-generate integrations between any software. He locked down Glean as an early customer because he had friends there. And it failed completely.

So he pivoted. This time, he refused to work with friendly customers who knew him. Instead, he did 10-20 calls per day with strangers who would tell him his product sucked. He posted on Discord communities at 3am, wrote technical blogs that went viral on Reddit, and created fake landing pages to see what integrations people actually wanted.

In one year, Composio grew to 100,000 developers and raised $30M from Lightspeed in just 3 weeks.

His contrarian take: in AI, asking users what they want will just get you faster horses. Built it instead, and watch their eyes light up.

Why You Should Listen:

• Why friendly customers will kill your startup.
• The 20 calls per day strategy that scaled Composio to 100,000 users.
• Why you can't validate AI products by asking.
• The exact Discord and SEO tactics that got their first thousand users without spending on ads
