We raised $550M at an $8.8B valuation.
A cap table tells you how a company intends to build. We built this round around investors with a long time horizon: established long-term holders, plus institutions that work with law firms and in-house legal teams every day and have a close view of where legal work is heading.
@Atreidesmgmt / @GavinSBaker led. @BaronCapital, @CapitalGroup, @Fidelity, @GladeBrookCap and @jpmorgan are new. Every major existing investor is in again.
Short-horizon money asks for growth at any price. Long-horizon money asks whether the business holds up. We’d rather deliver on the second question. ARR is past $200M, and the next $100M took us less than six months. Gross margin is healthy and the cost structure gets stronger as we scale. Patient investors let us keep it that way, because nobody is asking us to trade one for the other.
Thank you to every investor who joined, and to the customers and team who bet on us.
Adding a picture from when we signed the term sheet.
Back to work. LFG!

Excited and honored to be speaking at the @CFTC Frontier Forum next week! Looking forward to talking about compute and more broadly about how SI is rapidly changing our financial markets.
Super intelligence is poised to transform our financial markets.
Through the @CFTC's inaugural Frontier Forum, we are bringing together leaders at the intersection of technology and finance to explore the opportunities and risks of super intelligence and help shape the next frontier of American financial innovation.
Read more about our first Frontier Forum on October 28:

Thrilled to double down at @daytonaio: @ivanburazin, @JukicVedran and team are building one of the iconic companies of the AI era. We're grateful that they let us lead the Series B, after leading the Series A earlier this year.
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.

Tom was years ahead of the curve building infrastructure for companies to seamlessly support arbitrary transaction types and funds flow
Very cool to see that work coming to fruition and enabling the agentic economy
Fragment is automating commerce.
We think there are millions of businesses that haven't been invented yet. Not because folks lack imagination, but because it's too hard to build the financial systems that run them. Fragment removes that constraint.
Today, people run companies. With Fragment, they'll run on their own.

an agent's workflows are seldom the same; the next step an agent takes is not determined until the last one's been taken.
@neckelthomas and the Fragment team has taken a first principles approach to financial systems for agents...and making serious progress...

One thing I learned at Stripe is that moving money is only part of the problem. Knowing where it came from, where it went, and why is just as important.
As agents start making financial decisions and moving money autonomously, that infrastructure becomes more critical.
Excited to see Fragment building the financial primitives for this next era of commerce. Congrats to @neckelthomas and the team on the $12M raise!

I came to compute from credit, and the first thing I saw was how it gets paid for. An AI company signs a three-year contract and puts 20 to 30% down, out of the money it just raised. The fastest-growing industry in the world has been funding its most important input with its most expensive capital.
Today we announced a $250M prepayment facility with K8. Buyers finance the deposit against the contract instead of paying it from equity, and every draw is verified by us before it funds. Oil producers have borrowed against forward sales for decades. Compute couldn't, because there was no standard contract and no price to mark it against. Now there is. This is the first structure, not the last. There is a lot more coming from the @liquidcompute team, and the industry is going to look different for it.
Everyone wants to trade compute. Not many want to do the hard work of financing it. We do, because financing is where every real market starts, and we're building the rest of it: the index to price compute, the venue to trade it, and the exchange to hedge it.
If you buy compute and are tired of paying deposits from equity, or you allocate capital and want in on GPU-backed lending, whether asset-based or through this facility as it grows, reach out. Our inbox is open.
Liquid Compute and K8 announce a $250M prepayment facility to help compute buyers fund prepayment capacity commitments.
This facility makes compute financeable the way every other commodity already is, and we are already finalizing our first deployments with a few large inference clouds.
We're proud to build this with K8 as we bring the discipline of commodity finance to compute.
Adam Nelson retweeted
Almost every AI company or inference cloud we talk to has the same problem: they raise a round, sign a handful of large compute contracts, and a big chunk of the money goes straight into a deposit before a single GPU is turned on. Equity is the most expensive capital a startup has, and it's being spent on a bill that comes due in months. No other commodity has been so reliant on a single source of funding.
Today that changes. Alongside K8, we've launched a $250M prepayment facility that lets AI companies and inference clouds finance their compute deposits against the contract instead of paying them out of their round. The operator still gets paid upfront. The buyer keeps its equity for research, hiring and product.
It's the first financial product we've built on top of our physical exchange, and it won't be the last. Thank you to the K8 team for underwriting something that hadn't been done before.

Buying compute is often a lot more than just agreement on commercials between a neocloud and AI company. We wanted to offer a simple general overview of how compute actually gets built and how financing is the biggest bottleneck.

I’m excited to share that today @liquidcompute emerges from stealth with a $15 million seed round. We are announcing pending applications before the CFTC for Designated Contract Market (DCM) and Derivatives Clearing Organization (DCO) status to build the first regulated orderbook to trade both cash and physically settled contracts on compute.
The reality of compute is that it is heterogeneous and cannot be stored, functioning much like electricity rather than oil. Our approach focuses on developing a highly efficient short-term market to underpin a cash-settled derivatives layer, operating similarly to PJM or ERCOT sitting below liquid derivatives markets.
Over recent months, I’m also happy to announce that Liquid Compute has collaborated with leading financial firms like Susquehanna International Group, @BGCGroupInc and @wintermute_t to facilitate liquid OTC trading for AI startups, neocloud providers, and lenders.
This round was co-led by @chemistry and @FirstMarkCap , with participation from K8 Cap, Night Capital, @ufo_holdings, @TrueBridgeCP, Brainchild Holdings (@kalvepuri), @ycombinator, and angels such as Dmitry Balyasny, @taro_f , @JdotJdotF, Ethan Lin and others from companies like CoreWeave, Jane Street, OpenAI

Introducing Finality: Chargebacks for Stablecoins
Trillions of dollars are transacted today without a way to dispute a single payment.
Finality is the first to give enterprises dispute resolution to their customers without reversing blockchain transactions.
We're inviting payment providers, LPs, and arbitrators to help shape the network ahead of broader access.

EXCLUSIVE: Henry AI has raised a $16.5M Series A led by FirstMark.
Used by 150 commercial real estate brokerages to generate decks, the NYC startup is launching a new product, Henry Deal, to automate underwriting.

Damien Lewke (@abcbyDamien) is the epitome of founder market fit. Couldn’t be more excited to be working with him and the wildly talented team at @nebulocksec.
AI has rewritten the attacker playbook. The gap between an amateur hacker and a nation-state has alarmingly compressed, and the most dangerous attacks now look completely routine: stolen credentials, valid tokens, and sessions that slip past every tool trained to known-bad signatures. Nebulock flips the model: Vespyr, its autonomous threat hunting agent, works continuously across identity, endpoint, and cloud telemetry to hunt for how adversaries actually behave, already running 300M+ investigations and surfacing 4,000+ high-confidence findings that existing tooling missed, often within hours, in environments running best of breed detection / prevention tooling. What's in front of this team is even bigger: they’re building the foundational security analytics stack, baselined on every identity, endpoint, and resource, with agents that get smarter as the collective intelligence grows.
Join the hunt 🎯
