AI startup JuliaHub raises $65M to rival Simulink

while I know it's only a secondary concern behind their primary business interests, I'm very excited to see how this might translate into increased support and activity on Julia itself!

It's hard to decouple them as primary vs secondary because Julia is pretty central to what they're doing here. To my understanding, all the actual calculations that this is based on are in Julia, Dyad is basically a layer above it that gives a declarative interface, AI integration that understands that interface, and a GUI that makes it even easier (than the declarative language) to input the model. So funding for Dyad has pretty heavy incentives to go towards improving the Julia ecosystem because that's where its foundations are.

The paywalled (or subscription-walled) portion isn't too long, it's a pretty small article, but here it is: https://removepaywalls.com/https://www.axios.com/2026/04/30/...

Does anyone have a general idea of if $65m is typical, or larger or smaller than the usual funding amounts for these kinds of industry targeted "boring" software?

Despite the framing, I think Dyad's role is more to fill in the areas where Simulink is a pain to use and has been wrangled into shape for lack of better options, than to replace it. The agentic part can be a big pull though, if they can get it to reliably produce what the user, eg. the engineer, asked for, without having to spend more time correcting it than they'd have spent writing or laying it out. Seems plausible because this is a specialized niche-purpose AI, but still not 100% certain it can get there IMO.
