Google, Microsoft, Amazon, and Oracle have all adopted our open protocol for how AI agents talk to user-facing apps.

Today we announced $27M Series A to keep building it - and much more.

Led by Glilot Capital, NfX, and SignalFire.

@MikeRyanDev @codetv_dev @jlengstorf @joelhooks The trifecta!

[Mike Ryan @MikeRyanDev]

Love being on the @codetv_dev set. I’ve got something fun I’m cooking up with @jlengstorf and @joelhooks for frontend developers.

[Sam Julien @samjulien]

Early access for Slack & Teams in @CopilotKit is live now btw 👀👀👀

[Sam Julien @samjulien]

More of our customers and partners are asking for gen UI in non-browser surfaces. Think asking for agents to give you diagrams/visuals/other interactive elements in:

- Slack
- Teams
- VS Code (and all its forks)

Interesting signal & we are working to be the leader here.

[Sam Julien @samjulien]

Could not agree more

Both my floor and my ceiling have been determined by my skill and experience this far

[Matt Pocock @mattpocockuk]

@DanielSmidstrup Your skill level acts as a ceiling for the agent

So every skill you gain multiplies your output

Never been a better time to git gud

[Sam Julien @samjulien]

Early release is here, give me your feedback pleeeease https://t.co/GkFmdrwJ3b

[Sam Julien @samjulien]

My O’Reilly book manuscript is done and we are entering production!! 🎉

[Sam Julien @samjulien]

Merged my first PR to the A2UI docs! 🎉

Updated and corrected a few things about how @CopilotKit and AG-UI work with A2UI.

Having a blast partnering with Google on this protocol work!

[Sam Julien @samjulien]

@joelhooks Ooo love it!

[Atai Barkai @ataiiam]

Daytona 🤝 CopilotKit

🎉 Excited to release our new cookbook

In our first guide, your @CopilotKit Built-in Agent can run code inside a Daytona sandbox and return the result to your chat.

Shoutout to @ivanburazin, @ivanda_mislav and the Daytona team for making this happen alongside Mark Fogle, @tyler_cpk and @sofiiiiiasz.

Looking forward to more collaborations 🪁

[Uli 🪁 @ulidabess]

Daytona and @CopilotKit have been cooking 🧑‍🍳

You can now give your built-in agent a computer

We worked together to ship a tool that lets your agent execute code in a @daytonaio sandbox, and then returns the output in the chat.

Cookbook 👉 https://t.co/jFFdR3yjZw

Thrilled to partner with @ivanburazin and team.

More cookbooks and recipes coming soon 👀

[Sam Julien @samjulien]

@ulidabess @CopilotKit @daytonaio Big fan of @ivanburazin and @daytonaio from my work at WRITER, so great to see us teaming up with that team! 💪

[Sam Julien @samjulien]

@ceeoreo_ Yeah it’s very fun!

[Sam Julien @samjulien]

Building AI product requires many tradeoffs:

- UX vs AX (hopefully aligned)
- Cost vs speed
- Determinism vs non-determinism
- Latency vs accuracy

It’s a lot of fun but very tricky

[Sam Julien @samjulien]

@joelhooks “clean”
“load-bearing”
“directionally”
“my read”

so many 🪦
