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.

We're inviting payment providers, LPs, and arbitrators to help shape the network ahead of broader access.

Welp we're at this stage of my AI adoption curve...

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. "We're at the forefront of what I call the hard part of AI."

Nearly every large financial institution has an innovation team experimenting with stablecoins.  Nearly every F500 CFO is stablecoin curious. But enterprises are still transacting nearly zero volume. That gap is why we co-led Velocity's $38M Series A alongside our friends and Rain co-investors at Dragonfly. Velocity’s founder Eric Queathem spent nearly a decade at Worldpay leading global strategy and growth. He speaks CFO natively. Our references on him were remarkable in their consistency: top-1% mind, tireless operator, and exactly the person to build the team to 10x stablecoin adoption firstmark.com/story/from-300…

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 🎯 @sullivan @rak_garg @dannguyenhuu
