We just raised a $60M Series B at a $1B valuation to build @daytonaio into the Agent Cloud. @FirstMarkCap led the round, with all key existing investors and angels doubling down. We're also thrilled to welcome the founders of some generational companies aboard, including @patrickc (Stripe), @tobi (Shopify), @AravSrinivas (Perplexity), @BrendanFoody (Mercor), @oliveur (Datadog), @adamdangelo (Quora) and @ericsyuan (Zoom) We're a 35-person team. But that's about to change; we're hiring across the board, and we'd love for you to join us.

RT @joshuacirjak: SF what’s goooooood 🤝🏼

RT @saralucijad: @daytonaio team at the @UseCorgi cafe today - filming something really cool 🤫

Wearing a suit in SF is insane. People stare at you. Even other founders. Everyone's like “why are you dressed like that?” I would wear a suit every day if I could. I actually do often when I’m in New York or other cities where it's generally acceptable. Feel great in it. Croatia is even worse. People show up in flip-flops and shorts. I feel like a misfit everywhere I go.

Compute Love ❤️

Thankful for all the coverage around our raise 🙏

Starting my day off right

Daytona is building a cloud for agents that's like giving every agent its own computer. It has attracted founders of Stripe, Perplextity, Datadog, Mercor and others as angels, it says.

Strange but highly probable outcome: Muse takes ChatGPT’s users but Gemini keeps its own lane.

RT @borna_perak: The goal is to win the market so decisively that even Bending Spoons won't want our competitors.

Proud angel 😇

RT @abdullababakre: defining a new category: phone-use an mcp/api that gives ai agents their own phones cloud phones. real androids. real iphones. tell your agent what to do, and it can operate a phone just like you do. today, ai agents face three fundamental problems and phoneuse solves them 🧵

We’ve raised an oversubscribed $30M Series A1 led by @walden_catalyst to build the Global Compute Grid. We’re turning fragmented GPU capacity into one unified platform where AI teams can access, manage, sell, and orchestrate compute. Our mission: make the world’s compute unified, productive and liquid.

Interfaces are not going away. Some people keep saying the future is pure chat. "No UI, just talk to it." If that were true: - no meeting would have a whiteboard - pitch decks wouldn’t exist - You wouldn’t look at your phone screen You always need to show things and interact visually: drawing lines, previewing, whatever. Those needs don’t disappear because AI got better.

RT @TechCrunch: General Compute is betting on inference chips from outside the Nvidia ecosystem.

Honored to have @fkpxls on the captable!

RT @axiommathai: The largest math proof in human history is now computer-verified. Today, Axiom announces a complete Lean auto-formalization of the Classification of Finite Simple Groups, the "periodic table of symmetry." About 15,000 pages, built by over 100 mathematicians across generations.

More Daytona @PaceCap If the Daytona team were an LLM, people would write papers on how to train them. It’s only fitting that so much RL is now running on their computers, when the founders themselves are RL machines.

Daytona Compute Conference is back! Super excited about this 😎

Agents aren’t exactly malicious. The problem is they don't have any fear or recourse. If you ask an agent with no guardrails to get you a million dollars, it’ll find the most direct path (that path might be a bank database) Run agents in sandboxes with their own credentials, their own machines, their own access rules. Then you can see what they’re doing while they’re doing it, not after the disaster through audit logs. And observability for agents should look exactly like what enterprises already run for employees. The infrastructure/systems already exist.

COMPUTE is back! Join us for the second edition of Daytona COMPUTE, February 3–4, 2027, at the iconic Chase Center in San Francisco! 🏀 AI infrastructure starts here. Early Bird tickets are now available:

Idk why people scrutinize companies selling data so much. If it's old data you’re not using, sell it. They’re going to learn this stuff either way. You might as well make something off it.

RT @ivanburazin: We have a few Mac minis left over from our Daytona event in San Francisco. Thought we'd give 3 away to people building something cool. To enter: 1. Follow @daytonaio 2. Reply with what you'd build with a Mac mini and tag 2 people who'd build something cool with one. We'll randomly pick 3 winners and announce them on October 30th. Winners will be contacted directly via DM. Good luck! No purchase necessary. US residents 18+. Rules below.

None of these security incidents are a “they deserved it / had it coming” situation. We’re all next. And if you’re a competitor using this moment to poach customers, remember this is going to happen to you too. Sooner than you'd imagine. And then everyone’s going to remember the shade you're throwing at others right now. Have some empathy.

RT @pramanyaguda: Be honest: who here actually needs a Mac mini? Tell me why in the DMs.

Looks like a new Daytona use case. Luv it!

RT @joshuacirjak: A few new faces here, so figured I’d introduce myself. I’m Joshua, 27, Croatian-Canadian 🇭🇷🇨🇦 → Created videos for Adidas, Prada, Jägermeister, Samsung, Intersport to name a few 💻 → Lead videographer at Ultra Europe 📹 → Started IUTD Studios & built a transparent 35mm film camera, now sold in 60+ stores worldwide ✴️ → Recently joined @daytonaio to take care of brand & creative 🧪 → Built an audience of 100k+ on TikTok 📈 → Currently somewhere between Croatia & San Francisco 🇭🇷 I like turning crazy ideas into real things. Excited to share BTS with you here!!

I’m literally fine tuning models by using grokbot (@bot) and renting GPUs from @daytonaio what a time to be alive

When you bring in C-suite execs at your startup, you’re hiring them and their entourage. Their team accompanies them and so does their Rolodex. The person gives you access to relationships they’ve built over a decade and prospects they can call on day one. The risk is proportional too. If you have to fire them, a large chunk of the people under them leave too. Because they’re there for that person, not for you.

The only place to get a @daytonaio drink!

I love the new vibes coming from the @daytonaio team 😎

RT @pzakin: Two core beliefs driving our latest investment in Daytona: 1. @ivanburazin and @JukicVedran are sensationally talented founders; hard to overstate the talent, guts and grit behind their rapid growth. 2. We are intensely bullish on future demand for sandbox compute. Even beyond the prevailing use cases (background agents, RL, CI), I expect that emerging patterns of autonomy (autoresearch, simulation, "explorer" agents in non-verifiable domains etc...) will be voracious consumers of sandbox compute. A longer treatment co-written with @kevinyzhang on the fundraise and how we're thinking about the category.

I'm somehow related to all three Croatian unicorns now. - Infobip (the first one) acquired one of my companies and I worked there for almost 3 years. - The founder of Rimac Automobili (owns Bugatti and made one of the fastest road-going electric supercars) Mate Rimac is a dear friend - I also luckily co-founded Daytona (the latest entrant to the club)

RT @KaranVaidya6: Agents have a trust problem. Today’s models can do most work. What they need is the right boundaries. In traditional software, those were set at build time. With agents, they have to be set and enforced at runtime. Today we’re introducing Composio Firewall, the runtime boundary for agents. Millions of users and developers already use Composio as the runtime for their agents - giving agents tools, auth, and sandboxed execution. Now with our agent firewall every action an agent takes is evaluated using Jev and custom SLMs tuned by Composio based on real-world usage data. The firewall strengthens that existing boundary in both directions, checking the actions agents take and the information coming back to them through Composio. The advantage of the runtime boundary is that Composio Firewall verifies that the agent respects user intent and the boundaries set by the developer and user. Additionally, this provides the safety layer required to protect the user against malicious prompt injection as well as other attacks. Composio Firewall is live now for all Composio developers. Check it out at

If you look carefully, you'd find security holes in your infrastructure every day. Some are yours. Some are in the underlying layers. The only solution is to invest heavily to find them before someone else does. - HackerOne-type programs - Bounties - AI/humans jamming tokens at your codebase constantly

Excited to be back on etn. Joining the live stream shortly to chat about our fundraise and more
