Sherpa is an autonomous conversion rate optimization tool for growth and marketing teams who run their company website. After installing a single snippet, it watches how visitors behave, identifies where people drop off, and then designs, ships, and A/B tests new page variants on its own, including layout changes, copy edits, animations, and visual tweaks. Customers typically see a 15-20% lift on their primary conversion metric in their first 30 days , which is the pitch behind this Y Combinator launch.
The launch is anchored to a real customer story. Sherpa was used on Lindy's website to ship 40 experiments in 30 days and lift conversion by 30%, which the team turned into a short film as the launch video. The traction matters because most growth teams still treat experimentation as a manual project that requires marketers, designers, and engineers to coordinate for weeks per test, leaving the majority of pages on most sites under-optimized.
Sherpa is built by co-founders Ethan Kinnan and Norbu Sonam , a two-person team based in San Francisco. Norbu was previously a software engineer at Lindy, where he worked on onboarding optimization and computer use, and at Microsoft on Copilot image generation and Microsoft Designer , experience that informed the agent's approach to running experiments end to end rather than just suggesting them.

40 experiments in 30 days is either heroic or a great way to gaslight your own analytics dashboard. Curious which one Lindy got.

A movie. For a CRO tool. The bar for launch videos is now in low earth orbit and I am here for it.

genuinely inspired, my launch is in 3 weeks and now I have to go reshoot everything because apparently we're doing cinema now.

ok wait, one line of code and it just starts running experiments on your live site? that is either the dream or a Friday afternoon outage waiting to happen.

How does this play with existing analytics stacks though. If I'm already in GA4 plus Amplitude plus Mixpanel, where does Sherpa actually sit in the pipeline.

The pacing on that launch video is genuinely tight. Whoever edited it understood that nobody watches past 12 seconds unless something happens.

Already telling my portfolio companies to look at this. Conversion lift stories sell themselves to every B2B founder I talk to.

CRO as a category has been picked over for a decade. One case study with one customer is not a market, it's a testimonial.

hot take: autonomous experimentation is just a polite way of saying your PM is getting replaced by a cron job. fine by me honestly.

Polite ask: any chance one of the founders would chat about how the agent decides which experiments are worth running? Working on a piece about agentic CRO.

The thumbnail has the founders staring into middle distance like it's a Christopher Nolan trailer. Respect, but the type weight on the title card is doing too much.

Are Ethan and Norbu hiring? Got a forward-deployed eng who shipped CRO tooling at a Series B and is quietly looking.

Is this just VWO with vibes? Asking earnestly, last time I touched conversion tooling Optimizely was still cool.

Imagine paying experiment results out onchain so the agent has skin in the game. I'll see myself out.

This is the third agentic-CRO launch I've clocked this quarter and easily the best produced. The movie format is going to get copied within a week.
