Tien Chu

Founder of LATO, Predict how market participants behave

Company

Tien Chu is listed as a founder of LATO. The best investments come from conviction, and conviction comes from understanding a market deeply: its customers, its competitors, and where it's heading. Today that understanding is slow and expensive to build. Reaching the right people takes weeks, a commercial study costs $300k+, and each one starts from scratch. LATO does this research end-to-end, combining public data and the fund's own knowledge with first-hand interviews of a market's consumers, experts, and operators. This research grounds a simulation of the market to predict how market participants behave.

With LATO (YC S26) we aim to predict the future and give investors conviction. It's the most exciting work either of us has done. If you are investing or building, we would love to connect. PS: LATO means summer in Polish, a perfect coincidence that we are in the Summer 2026 batch! …more
