There’s big news in the distributed systems testing sector again. Antithesis, a platform focused on this field, has just secured a sizable amount of funding—a $105 million Series A round.

The lead investor is a major player: Jane Street, a veteran powerhouse in the quantitative trading world. Interestingly, they’re not just investing—they’re also using this system themselves. It seems they’ve tested it with real money and found it reliable enough to invest heavily.

The co-investor lineup is impressive as well: Amplify Venture Partners, Spark Capital, and Tamarack Global all participated. Among individual investors, there’s also a heavyweight—Stripe co-founder Patrick Collison joined in.

Testing distributed systems has always been a technical challenge, especially in high-reliability environments like Web3. Now that even traditional finance quantitative giants are betting on this direction, it shows that the market demand for infrastructure tools is indeed growing. After all, nobody wants their system to fail at a critical moment.

Jane Street only invested so much because they use it themselves—this is what truly means to vote with your wallet.

That number, 105 million... Jane Street is using it themselves, and that's the detail most worth noting. Real-money players never lie. Wait, is there actually liquidity starting to flow into infrastructure now? Need to dig into the financing terms carefully. Patrick Collison participated... Top players from traditional finance + co-founder of a payments giant. That's an interesting combo. The market efficiency of distributed testing is still in a rupture phase. Need to think about what this round of funding signals. A $105 million lead investment—Jane Street's investment logic has always been data-driven, which means they've already run their models.
