I’m thrilled to share that we have just closed two new funds: the $225M seed-focused Uncork VIII and the $75M opportunity fund, Uncork Plus IV. And today, we’re also celebrating @uncorkcap 21st anniversary. It’s been a long—at times tumultuous—but always incredible journey to reach the firm’s “adulthood” and I couldn’t be prouder of the team we’ve built and the portfolio of founders we’ve had the privilege of backing over the years. After co-managing Uncork with @bandrew in recent years, I’ve asked him to take on the role of sole Managing Partner as we prepared to raise these new funds. I’ve had an absolute blast leading Uncork for 21 years—helping shape the seed industry alongside my fellow “OG’s”—but the time feels right for me to step back from day-to-day management. I’ll continue working closely with our portfolio founders, sourcing new opportunities with my Partners, and investing in the next generation of frontier and deep tech entrepreneurs. I’ll also be carving out space for some long-overdue bucket list travel, quality family time, and launching a small wine project in Walla Walla, WA. Please join me in congratulating Andy as he leads Uncork into its next phase. We couldn’t ask for a better steward of the firm’s future. LFG!

Today marks Uncork Capital's 21st 🎂 That would usually be reason enough to celebrate but I'm also delighted to announce that we've raised $300M in new funds to back the founders building the next generation of category-defining companies 🚀 medium.com/uncorkcapital/…

For years, the AI industry has been obsessed with extraction. Turning documents into data. And it worked - extraction got really good! But extraction was never the hard part... The hard part is everything that comes after. The business logic. The exception handling. The human review loops. The schema enforcement. The production API. The monitoring. The drift detection. That's where every AI project stalls. That changes today with Bem's new Forge product 👀
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 🚀 Read more about why we're excited - link in comments!
Mirai@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 @marcinzukowski @matiii @gokulr @scooterbraun @krishnanvijay @benparr @MattPRD @adityajami and others. More on it at our blog trymirai.com/blog/mirai-rai…

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! 🚀 geekwire.com/2026/cloud-and…

For too long, GTM has been divided into specialists, creating a soul-crushing web of dependencies. But, speed is everything and dependencies are the enemy of growth. Enough is enough. Mutiny is killing all dependencies, once and for all. Now everyone can become a GTM athlete, creating highest quality (and on-brand) content.
Jaleh Rezaei@jalehr

The era of the specialist is over. Full-stack GTM athletes are taking over. For too long, GTM has been divided into specialists, creating a soul-crushing web of dependencies: - Sales needs a custom business case to close a deal, but Marketing is slammed. - Marketing has a winning campaign idea, but design and engineering can’t prioritize it. - CRO has 5 ideas for increasing sales productivity, but no GTM engineers to execute. In GTM, speed is everything and dependencies are the enemy. That's why we're giving GTM teams the full-stack capabilities they need to close revenue. Welcome to the era of the GTM Athlete. These are people who don't ask permission or wait in queues. They can do whatever is needed to take deals from cold to closed—research accounts, launch ads, create a business case, generate tailored follow-ups, and close deals. Sales rep brainstorms with their champion how to convince the CISO. 30 mins later sends them a polished business case with security architecture and ROI. By lunch time, she launches ads to the entire buying committee. The next day, the rep presents a custom deck to key decision makers and gets verbal commitment. No more begging. No more waiting. No more losing. Our vision is to build the AI Swiss Army knife that turns specialists into GTM athletes. Today we are launching a critical capability that enables this vision: an AI agent that can create anything customer facing. You can now create executive business cases, deal follow-ups, landing pages, ABM campaigns and more, all by yourself. Unlike other AI tools, our agent plugs into your brand and data to create materials that actually look and sound like you. Sign up on our website. We're letting people off the waitlist every day, with 30 days of unlimited AI usage. I’d love to hear your feedback.

When I first led @Gamma's seed round in 2021, ChatGPT didn't exist. Waymo wasn't yet publicly available. Humans wrote the vast majority of code. Fast forward to late 2025 when I invested a second time with @uncorkcap, the world had transformed, and Gamma's progress massively accelerated ($0 ➡️ $100M!), but so many things remained the same.

Okay so, we just found that over 50 papers published at @Neurips 2025 have AI hallucinations I don't think people realize how bad the slop is right now It's not just that researchers from @GoogleDeepMind, @Meta, @MIT, @Cambridge_Uni are using AI - they allowed LLMs to generate hallucinations in their papers and didn't notice at all. It's insane that these made it through peer review👇

Super excited to have joined my old friend @mikeeisenberg on the Invested podcast for a wide-ranging conversation (listen here: bit.ly/4alK2ew). Michael and I go way (way) back, and it was a blast to reminisce about the early days of seed investing—and how the market has evolved over the past 20+ years since I started the firm and raised one of the first seed funds in history. Thanks to Michael and the team at @aleph for the invitation. Take a listen!

Introducing Anything Max: Vibe Coding that's leaps above Lovable and Bolt We've raised money at a $100M valuation and built what we believe is the future of vibe coding. We asked 100 vibe coders to build their apps side by side on Lovable, Bolt, and Anything Max and they rated Anything Max the winner across all 3 categories - accuracy, design, and 'overall'. Here's why: • Full-stack control: Max can test backend hooks, branch database states, and debug issues, because Anything owns the full infrastructure. • Max can load up your app in its own browser and click on all buttons like a human tester to find all edge case bugs, then trace the bug across the stack - could be a frontend, backend, or a database issue (only we can do this, read #1) and autonomously fix it with 97% accuracy. Lovable and Bolt build prototypes, but Max users are building production-ready apps and already charging money for them. Blake built a gut biome app to $10K run rate Anthony built a referral tool to $20k in revenue Yuri built a suite of apps doing $40K Build your app with Max: createanything.com/max -------------------------------------------- We're hosting a $100K Hackathon to help people grow their app to $10K MRR. - We'll teach you everything we know about growing to 1M users. - You'll have 30 days to build a real product in public and get paying customers for it. If you do it well, you can start the New Year with a functioning business. Retweet and comment “LFG”, and we’ll send you a $100 discount code and the link to participate

Congrats team! This milestone reflects the dedication of your talented team and the many developers, maintainers, and early adopters who have indelibly shaped the language and ecosystem. For the uninitiated, Unison is a functional programming language built around one big idea: let's identify a definition by its actual contents, not just by the human-friendly name that also referred to older versions of the definition. You can do so much more while doing much, much less.
Unison | @unison-lang.org on bsky@unisonweb

🎉 Unison 1.0 has landed! After years of engineering, design, and community collaboration, we’re excited to announce this milestone! Spread the word! unison-lang.org/unison-1-0/

Excited to share that @GammaApp has raised a $68M Series B at a $2.1B valuation, led by @sarahdingwang @a16z with participation from @uncorkcap! It’s been a privilege to have been part of the Gamma story since leading their seed round with $0 in revenue and a handful of users in 2021.
