ArcaLabs has raised a pre-seed round with participation from Contrary, the San Francisco venture firm built around a simple conviction: at the root of every iconic company is one thing — extraordinary people.
The investment backs our work building compliance-first AI agents that run sell-side and private-equity workflows end to end, grounded in trusted financial data with an auditable trail behind every figure.
Why Contrary
Founded in 2016 by Eric Tarczynski, Contrary finds and supports exceptional people before the rest of the world recognizes how special they are — pairing deep research with a network of scouts and venture partners to back founders early, often before they have started a company. ArcaLabs CEO Dilzafer Singh knows that network from the inside, having served as a Contrary Venture Partner. Portfolio companies include Anduril, Ramp, and Zepto, alongside the widely read Contrary Research.
