in the age of agents, surely durable execution is a must.

but the money being raised - what is it for ? go to market ? sponsorship & I like that temporal sponsored Crystal Palace.

we've so many good durable execution engines.

this is the type of VC pollution that will cause companies to end up being acquired by an Italian silverware company (bending spoons).

Buying DRAM?

I’m in an interview loop with them. Hopefully that money is for building my wealth.

Can someone tell me why people prefer temporal over something like https://restate.dev?

AI workflows are a convenient fit for temporal, their platform is great for much more than just those. It’s an elegant and easy to use solution for a lot of workflow needs.

Those two don't really compare. Temporal has been around 3 years longer and is a much more heavyweight system. Temporal can support workflows that sleep for months at a time and still reliably finish.

I'm sure there is a place for restate.dev, but it isn't in the same place as Temporal.

Restate is directly inspired by Temporal.

> Our annualized revenue run rate is up more than 200% year over year, and net dollar retention's stayed above 200% since February. In August alone, the platform processed 1.9 trillion billable actions, up more than 350% year over year, while open source installs passed 43 million, up 134% since December 2025. We're now working with more than 4,300 paying customers, up 139% year over year, including OpenAI, Snap, NVIDIA, and JPMorgan Chase.

Congrats to Temporal! They'd just previously raised in February, https://temporal.io/blog/temporal-raises-usd300m-series-d-at...

Any absolute rev numbers?

Can someone shed some lights on what temporal does? Their blog says [1]

Durable Execution offers three key benefits:

    It improves application reliability by providing fault tolerance.
    It simplifies code by allowing it to focus on the goal instead of potential problems.
    It accelerates development by eliminating the need to write complex error-handling logic.
So... like exception handling? or something like erlang's let it crash mantra?

Why is it such a big deal? Genuine question, not trying to be snarky

It’s an async job runner that scales well. Yeah they advertise a lot of fancy features, but really what they are selling is basic infra. Companies could set the same thing up with an in-house team, but it’s pretty great to be able to click a button and start running workloads at thousands of RPS without needing to figure out the internals.
