Uncork Capital

Uncork is a seed-stage venture firm investing in founder potential long before it’s obvious. We invest in companies that push industries forward.

Since launching in 2015, @LaunchDarkly has been synonymous with enterprise-grade feature management (50 trillion feature evals per day, serving many of the most exciting companies in the world).

Today they're announcing AgentControl, the first product as they become the runtime control platform teams trust to move quickly with AI. While staying in control of code (and agents) in production, of course. Very excited for LD's next chapter! 🚀

Venture is hard to break into because there’s no clear path - just signals, networks, and guesswork.

Delighted to welcome James, Andreas and the Unkey team to the Uncork portfolio! APIs remain the backbone of the modern internet but until now the tooling to build and deploy them remained entrenched in the stone age. No more - Unkey is the way that every ambitious technology company will serve APIs, tokens, and whatever comes next 🚀

@amperoshealth raises a $16M Series A led by Bessemer. Excited to see the team hit this milestone!

I sat down with @mmiernowski to talk about his journey, customer relationships, and knowing when it was time to raise the A.

New site. New brand. New chapter.

Unkey Deploy is in public beta. Git push, ship to production on real servers.

No cold starts, no serverless limits. Free until we ship GA.

Ship APIs, not infrastructure.

We raised $72M from Sequoia/YC and hit 8-figures in ARR. Then we shut it all down & rebuilt the company from scratch.

Today we’re launching the new Mutiny: the first AI agent for GTM teams to create anything customer-facing, in minutes.

Gerri 2.0 is live! Our AI agent for contract negotiation. Contract review is a team sport, but every tool out there is built for one lawyer working alone. Gerri fixes that.

We launched Uncork's new brand yesterday and two of the core tenets are investing before it's obvious and sticking around for the long-term. I like to think we do that with every portfolio company but Coder's journey exemplifies that even more than most.

We are the only VC to have invested in every single round - long before it was obvious, through the messy middle, and after it began to inflect. This is what we do and I couldn't be prouder to be an ongoing part of their eight year overnight success story. Onwards! 🚀

We're excited to announce a $90M Series C led by @KKR_Co with participation from QRT, @uncorkcap and other existing investors! Learn more: https://t.co/tTb2tqZ5MS

[Andy McLoughlin @Bandrew]

Venture firms rebrand for all kinds of reasons. Sometimes it's genuine evolution - the identity finally catches up with who the firm has become. Sometimes it's camouflage - a way of looking like a different kind of firm than the one the last few years revealed. And sometimes it's just that the old website was embarrassing and someone finally had enough.

Ours is mostly the first, none of the second, and just a touch of the last :)

Today we're launching a new brand and a redesigned website. The logo is refreshed. The palette is cleaner. The typography is sharper. And the site actually reflects how we think in 2026.

Today, we're launching AI Vision.

The first AI slop detector that exposes content as you scroll.

[bem @bem_hq]

AI got great at reading documents.

But reading was never the hard part.

The hard part: turning extracted data into a running operation.

Today we shipped Forge. It closes that gap.

Describe your operation. Drop your data. Deploy. 🧵

Delighted to announce @uncorkcap's investment in Mirai (@trymirai), the platform to make on-device inference seamless, fast and multi-platform (Apple silicon today, Android soon).

Mirai’s co-founders, @Darkolorin and @dmitrshvets, independently built Reface and Prisma: early on-device AI products used monthly by hundreds of millions of people globally 🚀

Today, @trymirai is announcing a $10M seed round led by @uncorkcap , with participation from an incredible group of angels including @dps, @FrancoisChauba1, @marcinzukowski, @matiii , @gokulr, @scooterbraun @krishnanvijay , @benparr, @MattPRD, @adityajami and others.

This funding accelerates our mission to make on-device AI inference accessible to every developer, turning what requires specialized systems teams today into something that integrates in a few lines of code.

Every modern phone and laptop has AI silicon, but most developers can't access it.
@trymirai removes that barrier.

With this round, we're focusing on working with model makers to bring their models on-device across text, voice, and vision.
As cloud inference costs become unsustainable for real-time workloads, on-device execution offers better economics, eliminating per-inference costs while improving latency.

Models running on-device are becoming a new capability layer where developers can build system-level experiences independently. Inference becomes the programmable layer.

We're building the infrastructure layer that enables that future.
There's so much more to build, and we're just getting started.

Excited to have Uncork Capital and this incredible group of investors and angels joining us on the journey.

[Mirai Labs @trymirai]

We raised $10M led by @uncorkcap to make on-device AI inference accessible to developers building on Apple Silicon.

We're using the funds to expand model coverage across text, voice, and vision, working directly with model makers to bring their models on-device where latency, cost, and privacy favor local execution over cloud.

Our proprietary inference engine is up to 37% faster than Apple's MLX with up to 59% faster prefill.
Developers integrate it in a few lines of code without needing specialized systems expertise.

The runtime supports hybrid deployments, routing inference between device and cloud seamlessly.

Models running on-device are becoming a new capability layer where developers can build system-level experiences independently.

We're building the infrastructure that enables that future.

The round includes participation from an incredible group of angels including @dps @FrancoisChauba1

I'm excited to announce @uncorkcap's investment in @DuckbillHQ, leading their $7.75M seed round.

Over the last decade, Duckbill has become the go-to consultancy for the "nine figure club", i.e. the world's largest spenders on cloud infrastructure (including names like Delta Airlines, Ticketmaster, Epic Games, NewRelic, Washington Post).

Co-founders @mikejulian and @QuinnyPig are now productizing their encyclopedic knowledge and strongly-held views into a platform for every business consumer of cloud infra (AWS, Azure, GCP), SaaS (Datadog, Snowflake), and AI tokens (Anthropic, OpenAI).

Their contrarian pitch: the cloud cost management sector, commonly known in the industry as FinOps, is fixated on making bills smaller, when the real problem is that nobody can predict what the costs will be next month. Unsurprisingly (not), CFOs love predictability.

For any seed investment I ask the following questions: is the market large, is the market growing, and do the founders have an unfair advantage. The answer for all of these is a resounding yes (Corey's legendary podcast, "This Week in AWS", provides reach and authority that any CMO will kill for.)

Welcome Mike and Corey to the portfolio, and a big yay for another Uncork and @heavybit co-investment! 🚀
