Shensi Ding, co-founder and CEO of Merge, explains how the integration platform rebuilt itself twice for the AI era after starting in 2020, and why AI agents are useless without integrations. Merge began with accounting and HR connectors, watched early customers die, then pivoted to serve AI companies with unified APIs and a smart LLM router. Ding describes building the first AI product at night with her co-founder and one engineer, and how marketing became an engineering function, including a dinner bot that 10x'd customer events (from one or two per quarter to three to five per month). She argues most public MCP servers quietly fail, with a 60% success rate, and that startups should go all-in on enterprise for stickier revenue. The episode also covers the Embarrassment Framework for uncomfortable outreach and Merge's 6% marriage rate among its 140 employees.
Shensi Ding is the co-founder and CEO of Merge, the connective infrastructure that plugs into every tool. Most founders get one founding story. Merge has had three. Merge started in 2020 building boring integrations, watched its first customers die off, then rebuilt itself twice for the AI era. Not many founders talk this honestly about tearing up their company, and there’s a lot of lessons for others trying to do the same. We get into why AI is useless without integrations, the night-shift build of their AI transformation, the time they almost hired a foreign spy, why Shensi thinks founders with an EA are moving too slow, the Embarrassment Framework, why 60% of public MCP servers quietly fail, how a dinner bot 10x'd their customer events, and why 6% of Merge employees get married.
