LATO

YCombinator

Agent-native research and simulation platform for investors

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 customers, experts, and operators. This research grounds a simulation of the market to predict how market participants behave.
