Run your own investment firm.

Build your specialist team

Choose from a library of ready-made specialist profiles — small caps hunters, contrarian plays, bond market scouts, and more — or define your own strategy from scratch using a custom prompt. Each agent is configured with a specific investment philosophy and a distinct lens for reading the market. When a specialist gets to work, it draws from a wide range of sources: international financial press including the Financial Times and The Wall Street Journal, exchange regulatory filings, quarterly earnings releases, investor presentations, news wire announcements, and fundamental data across balance sheets, income statements, and sector multiples. One specialist might focus on cash flow signals buried in microcap quarterly reports; another might cross-reference macro headlines with contrarian price action in the market. Every agent synthesizes all of this into a unified research view — filtered through its own thesis, not a generic algorithm.

Simulate every strategy

Once your specialists are configured, put them to work. Each agent runs its own simulated portfolio — making paper trades based on its research conclusions, logging entries, tracking positions, and recording exits. No real money involved: this is a laboratory for your investment thinking. You can run a small caps specialist and a contrarian agent simultaneously, watching both portfolios evolve under the same market conditions. The simulation captures the full investment cycle — from initial thesis to final result — so you see not just which calls were right, but how each agent reasons through uncertainty, sector shifts, and company-level developments.

See which thesis wins

When two agents have been running in parallel, the results tell a story. Mesa puts them side by side so you can see exactly which thesis performed, by how much, and under what conditions. Was the contrarian play right when the market overreacted? Did the small caps specialist pick up signals others missed? The comparison goes beyond raw returns — you can trace performance back to specific decisions each agent made, understanding not just who won but why. Over time this builds something more valuable than a single winning trade: a clear picture of which investment philosophy actually fits the market you're operating in.
