Matt
Riley

Most founders sell their company and celebrate by announcing their next company. Matt Riley sold Swiftype to Elastic in November 2017 and spent the next eight years making the acquisition work. That's the unusual part.

Site search was broken when Riley started paying attention to it. Not broken in a "we should improve this" way. Broken in a "every website you visit has search that returns irrelevant results and everyone pretends that's fine" way. He'd seen this up close at Scribd, where he'd gone from Senior Software Engineer to Director of Products in under two years. When you move that fast, you notice where things are broken.

So in 2012, he and co-founder Quin Hoxie applied to Y Combinator with a search-as-a-service startup called Swiftype. They got in. YC Winter 2012. The batch that would come to define what a focused, technically excellent SaaS product could look like.

What happened next is almost too clean to believe. Andreessen Horowitz, NEA, and Kleiner Perkins led a $1.7M seed round. Then a Series A. Then a $13M Series B in 2015 that brought total funding past $20M. Companies like Scribd, Airbnb, and GitHub used Swiftype to make their products searchable. The product worked. The customers stuck around.

Elastic acquired Swiftype in November 2017. Riley went with the company - not as a footnote in the press release but as VP of Product, Enterprise Search. He climbed from there to GVP and General Manager of Search: owning product, engineering, design, and developer relations for one of the most widely used search platforms on the planet.

He wasn't just integrating what he'd built. He was defining where Elastic's entire search narrative would go next. Through the era of the Gartner Magic Quadrant recognition, through the Forrester Wave leadership, through the emergence of vector databases, retrieval augmented generation, and LLM-powered search - Riley was the person steering the technical and product story.

In late 2025, he stepped back into the YC orbit. Not to raise money this time. As a Visiting Partner - one of a small, selective group of experienced operators who advise founders during active YC batches. The whole arc compressed into a single elegant loop: YC batch founder to YC batch advisor.
