JuliaHub raises $65M to challenge Simulink with AI-augmented engineering simulation
JuliaHub, a startup combining the Julia programming language with AI agents for complex system modeling, announced a $65 million Series B round led by Dorilton Capital, with participation from General Catalyst, AE Industrial Partners, and former Snowflake CEO Bob Muglia. Alongside the funding, it released Dyad 3.0, its platform for simulating systems like cars and aircraft, aiming to displace MathWorks' entrenched Simulink tool.
Why it matters: The funding signals a bet that AI agents and a modern language can crack the engineering simulation market, which has been dominated by Simulink for two decades. This represents a potential new cohort pattern — using agentic coding tools to update legacy technical computing workflows, similar to how AI coding assistants are reshaping software development. However, the incumbent's deep surface area and domain lock-in mean JuliaHub faces a long climb, requiring more than just capital to unseat an entrenched tool.
Bob Muglia, a veteran of Microsoft and former Snowflake CEO, acknowledges the challenge: "Simulink has been around for 20 years. It has a lot of surface area and we haven't covered it all yet." This mirrors the dynamic often seen in enterprise infrastructure transitions, where newcomers must achieve feature parity while offering a compelling new paradigm. The round's size — modest by AI standards — suggests a focused, capital-efficient approach rather than a scorched-earth assault.
