[Abstract @AbstractVC]

We’ve been quietly building Abstract for 9 years. Thank you to @patrick_oshag and @domcooke @joincolossus for giving us the opportunity to share our story.

We’re just getting started!

Samir Menon @blintzbase and I are thrilled to announce Sail @sailresearchco ! We build infrastructure for long-horizon agents: inference served at unbeatable prices-per-token for open models, plus sandboxes designed to run for days, weeks, or longer.

We've raised $80M, w/ our seed led by @Sequoia
and series A led by @KleinerPerkins. We're using this capital to build the most efficient infrastructure for long-horizon agents.

What makes agents so different? Unlike a human waiting at a keyboard (top priority: speed), agents need scale, reliability, and sustainable cost. Sail finds this efficiency everywhere in the stack: we carefully choose our chips, write custom inference engines, and run a global controller that fully utilizes every computer in our fleet. Tight integration from silicon to API lets Sail open up the cost / latency frontier to our customers - the most patient agents can now access 10x more intelligence per dollar.

We're excited to be working with great companies like
@parallelweb, @detaildotdev,@Jackandjillai, and @quadrillion_ai to deploy long-horizon agents with trillions of tokens.

Our team is thoughtful in our engineering craft and relentlessly ambitious in our pursuit of peak performance. We previously trained at companies like NVIDIA, OpenAI, Google, and so many trading firms. Now we're ready to do the work that will define our careers, in the most compute intensive market of all time.

Welcome to the era of abundant intelligence. We can't wait to build with you!

We’re excited to double down in @NewLimit’s $435M Series C.

NewLimit is one of the most ambitious companies we’ve ever backed. Excited to see what they accomplish over the next decade.

[Ramtin Naimi @ramtinnaimi]

Congrats to @SocketSecurity on their Series C at a $1B valuation.

Security is a winner-take-all market. The company that sees the most attacks builds the best detection, which attracts more customers, which in turn surfaces more attacks. Socket’s flywheel is operating at scale now.

We backed @feross before the market fully appreciated how large this category could become, and the pace at which enterprises have consolidated around Socket over the last year has surpassed every benchmark we track.

[Ramtin Naimi @ramtinnaimi]

Congrats to @faionur and the @thestatusai team on their launch!

Status is building a new kind of AI native entertainment platform. The engagement metrics are already some of the strongest we’ve seen in consumer AI, and it’s still early.

Proud to have led their round.

[Ramtin Naimi @ramtinnaimi]

Today we’re proud to announce that we’re leading Dust’s $40M round.

Most enterprise AI is still single-player. Dust is multiplayer, humans and agents collaborating together, with knowledge compounding across the organization.

300,000+ agents have already been deployed on the platform.

Dust isn’t just building AI tools. They’re building the infrastructure for AI-native companies.

Excited to partner with @gabhubert, @spolu , and the @DustHQ team.

[Ramtin Naimi @ramtinnaimi]

Congrats to @Vapi_AI on this latest raise. Great product and one of the hardest working teams I know. Proud to be one of their earliest backers!

[Ramtin Naimi @ramtinnaimi]

World class team achieving great results. We’re proud to have been early supporters.

[Ramtin Naimi @ramtinnaimi]

The @p0 team is ripping. Very excited to be involved. 🚀

[Ramtin Naimi @ramtinnaimi]

Congrats to @yoland_yan and the @ComfyUI team! They’re building something special.

[Ramtin Naimi @ramtinnaimi]

Excited about this one!

[Ramtin Naimi @ramtinnaimi]

Congrats to the @extradotemail team on their launch. Email should feel effortless, and Extra makes it actually enjoyable. A beautiful inbox built around your life, not just another place to sort messages. Thoughtful product, clean design, and a fresh take on something billions of people use every day. Excited to watch this one grow. 🚀

[Ramtin Naimi @ramtinnaimi]

Congrats to the @FactoryAI team on the raise. @matanSF is an unstoppable force, and this team is just getting started!

[Ramtin Naimi @ramtinnaimi]

Proud to be backing @SriViswan and @SycamoreLabs in their $65M Seed round. They’re building the operating system for AI agents, letting enterprises discover, deploy, and manage fleets of agents with real governance, observability, and control. A foundational layer for the AI native enterprise.

[Ramtin Naimi @ramtinnaimi]

Proud to be co-leading @doctronic Series B with Lightspeed and partnering with @mattpavelle, Adam Oskowitz, and their exceptional team. They’re building the AI-native front door to healthcare, pairing a 24/7 AI doctor with real clinicians to expand access and lower cost. A glimpse into what modern care delivery will look like at scale. https://t.co/mU9KcikpeD

[ComfyUI @ComfyUI]

Two massive updates for the ComfyUI ecosystem today:

1️⃣ App Mode: The power of the node graph, now behind an easy-to-use interface. Turn complex workflows into custom apps.
2️⃣ ComfyHub: A brand new home to discover, run, and share community workflows and apps instantly via URL. Try ComfyHub preview via https://t.co/kQxsxBs2bB

Create in App Mode. Share on ComfyHub.

210 days ago, @naturalpay was just a one-pager and a memo.

Today, we’re coming out of stealth.

Natural is the agentic payments platform powering frictionless money movement between agents, businesses, and consumers.

Wallets. Payments. Ledgering. Routing. Identity. Compliance. Credit. Observability. Risk.

Everything needed to move money. Engineered for agents and designed for humans.

These primitives give you the ability to transact without becoming a payments expert or stitching together a dozen fragmented tools.

Huge thanks to our team of 10 (soon to be 25), our early investors, and the supporters who believed in this vision from the start.

If you want to help shape how money moves over the coming decades, we’re hiring.

And if you’re building agents you should probably be moving money too. Reach out.

Read more about Natural and the products we’re launching in the blog below.

Huge congratulations to @WorkOS and @grinich on closing their $100M Series C at a $2B valuation.

They’ve redefined enterprise auth and user management, making it dramatically easier for developers to build secure, scalable applications. Today, they power companies like OpenAI, xAI, Anthropic, and Cursor, and have firmly established themselves as the category leader.

Proud to have co-led their Seed and excited for what’s ahead.
