Predict how market participants behave

About 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.

    Tien has never been to US. I have never been to SF. And now we are both here, for Y Combinator! 11+ years ago, when we first met in high school in Poland, neither of us could have imagined this. We are incredibly excited to join the Summer 2026 batch and work with Gustaf Alströmer as our YC Partner. What excites us even more is what we are building. 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
