Sherpa is an autonomous conversion rate optimization platform that behaves like a tireless growth engineer sitting on top of a marketing site. It analyzes raw visitor sessions, identifies where users hesitate, drop off, or misread the page, then generates and ships page variants with new headlines, layouts, and calls to action. Customers in the early cohort report 15 to 20 percent conversion lift within the first thirty days.
Unlike traditional CRO tools that surface insights for humans to interpret, Sherpa closes the loop. It writes the variant, runs the A/B test, monitors statistical significance, and deploys winners, freeing in-house designers and engineers from the experimentation backlog that usually buries growth teams. Experiments still flow through an approval workflow so brand owners stay in control, and the company says it has already analyzed more than 7.3 million sessions across its design partners.
Founded in 2026 by Ethan Kinnan, a former forward-deployed engineer at Lindy, and Norbu Sonam, an ex-Microsoft Copilot and Designer engineer who ran more than fifty growth experiments at Lindy, Sherpa operates as Everest Labs, Inc. out of San Francisco. The company is part of the Y Combinator Spring 2026 batch under partner Andrew Miklas, with PostHog, Slack, Google Calendar, and Jira referenced in its workflows.
