Today we are releasing Laguna S 2.1.
At 118B total parameters, with 8B active per token, it does the work of models several times its size on agentic coding. It is remarkably persistent across long-horizon tasks. And it is small enough to run on a single NVIDIA DGX Spark.
It is far more capable than anything we have created before, and I think it redefines what a model in its weight class can do.
Laguna S 2.1 is an important model for Poolside. What it represents is even more important.
If, five years ago, I had read a book that said that by 2030 everything economically valuable, scientifically interesting, and personally meaningful would be built on intelligence contracted from three or four companies, I would have called it dystopian science fiction.
We are at a fork in the road of what kind of world we can have.
I believe intelligence should and will become a commodity. The question is whether that intelligence comes from three companies, or from many people who can build it, own it, and shape it.
The open ecosystem will not win by being the best in its own category. No one cares who is king of the open-source kingdom. People want the best intelligence for the task they are trying to do, with the right balance of quality, speed, cost, and control.
If we want a different future, open models have to be on par with, or better than, their closed equivalents.
Laguna S 2.1 is a meaningful step in that direction: capable enough to compete far above its weight class, efficient enough to run on hardware you can own, and open-weight so anyone can build on it.
Open-weighting our models is the contribution we can make today toward a world where intelligence can be built and owned by many. And we will keep doing it.
I am very proud of this team’s work. A big shout out to everyone at Poolside who made this possible, from infrastructure and data to architecture, pretraining, post-training, evaluations, and inference.
Laguna S 2.1 is available today under the OpenMDW-1.1 license, with weights on Hugging Face and access through OpenRouter and our API.
We are building toward a future where the most capable intelligence in the world can be owned and shaped by anyone. Laguna S 2.1 is one step. We are going to keep building until that future exists.

Today we're releasing Laguna S 2.1, our most capable model to date.
It's a 118B total parameter Mixture-of-Experts model with 8B activated per token, a context window of up to 1M tokens, and thinking and no-thinking modes.
Capable enough to hold its own against models many times its size. Small enough to run on a single @NVIDIAAI DGX Spark.
Laguna S 2.1 is fully open under OpenMDW-1.1, with weights available today on @huggingface

We're excited to announce Ciridae's $20M Seed, led by Accel, with participation from a16z, General Catalyst, Sunflower, Backcountry, and our friends and family.
Jack (@weissenberger_j) and I met years ago through our then-girlfriends, now wives, and have been hacking on projects together ever since. He was building AI for enterprises at Apple and Tenyx. I was at a16z, watching the same businesses try to adopt it and fail. We compared notes and realized the options for enterprises were not only bad for the business but bad for the operators! We looked at each other and said, “I think we can do this better…”
Since then, working with startups, governments, and PE-backed businesses, we have made every mistake worth making, and only now feel like we're beginning to solve the real problem of enterprise-wide AI Transformation.
This “real economy”, the businesses that keep this country running, have been under-appreciated by Silicon Valley and under-transformed by New York. Yet these are the businesses with the most to gain from AI and the least equipped to capture it.
The world does not move itself.
Ciridae is the AI Transformation Firm for the real economy. We embed with businesses that move the physical world. The distributors, construction, logistics, home services, staffing, and more, and rebuild their core operations as AI-native operating systems. End to end. One accountable partner. In weeks through our platform.
As the models become intelligent enough to accomplish most knowledge work, the economy’s bottleneck is now Transformation, the work of integrating intelligent software into a business and rewiring the business so AI runs the operation and people run the AI.
We believe AI Transformation is a new problem that requires a new business. New team, new technologies, and new business model. Not a Frankenstein's monster of transformation in parts.
In 2025, we hit high-seven figures in revenue, grew profitably, worked with governments with Trillions in GDP and PE Funds totalling Trillions in AUM.
@Accel and @ChristineEsser backed us to scale the team, deepen the platform, and bring AI Transformation to more of the businesses that need it most.
If you lead or back a business that wants AI to be the reason you win, reach out.
If you want exposure to real problems, with real ownership, and work alongside the highest-merit team you can find, reach out.
One business at a time. More to do. Onwards.

🚨 NEW EPISODE FOR EUROPE'S MOST AMBITIOUS STARTUPS 🇪🇺
And this might easily be the best video we have done so far! The company, their product and the team is just insane.
The goal of this company is to make money out of thin air – literally. No joke.
TLDR: Heavy machinery, in the middle of London, easily one of the most cracked team is met in a while, and their first test site? A military base.
What's crazy to me is that they are so heads down that nobody knows them yet… but still they already raised GBP 10M+ from the founders of stripe (@patrickc @collision), @natfriedman, @HarryStebbings, @pinverrr, @taavet and @pluralplatform and many more.
The Company is RIVAN – @Rivanindustries
Their product? Getting the CO2 out of the air and combine it with H2 from water -> to create gas, which they directly pump into the network grid to make money.
The same kind of gas we currently have to pay Russia for… we fight wars for… just without drilling into the ground and releasing CO2, but "mining the sky" instead!
This kind of tech is still in early stages – and tons of hypotheses have to be validated – but in the next five years the math can work out and if there's a team to figure this out, it's this one.
I took my camera and visited @harveyhodd and his team in their warehouse office in London and joined him to their first test site on a military base. I am a big fan of this guy. Intensity, obsession, technical competence. And the whole team is like this.
In the video you will see how everything works… every machine… but also how they keep urgency in the team… how they pay people to move closer to the office… why they are already running a military base only a few months in… how this can even ever work economically… and how the hell do you avoid everything blowing up – literally.

Max pain across tech right now, no end in sight. I wrote about how not to drive your startup off a cliff

"Wednesday will mark 238 days without a tech IPO worth more than $50M, surpassing the previous records set in the aftermath of the 2008 financial crisis and the early 2000s dotcom crash, according to research by Morgan Stanley’s technology equity capital markets team" via @FT

Increasingly becoming convinced that now is a great time to tackle a meaningful problem with 2-3 people, raise $500k - $1.5M at a fair valuation, and do some heads down building. Seed funds are open for business, talent is looking for work, and no shortage of problems to solve.

As startups grow there is extremely strong pull into what I call the death spiral of bullshit.
More people -> more teams -> more buy-in required -> more meetings -> being persuasive rewarded more than building -> builders leave -> nothing gets done

As a founder & investor I've done >1000 reference calls
They can be *the* most valuable data for hiring & investing. I can hire/invest based just on references (no interview/pitch needed 😎)
But most "references" are a waste of time

We've done c. 12 pre-seed investments to date (mostly UK / France). Ping [email protected] or @pinverrr who's point on this. Go @stride_vc :-)
Which UK investors will invest in a true angel/pre-seed round (e.g, pre-product, raising 250k)? These are often the hardest rounds to raise.
-@kirst Octopus 1st check
-@passioncapital
-@seedcamp
-Alma angels
Who else? Please share ideas to help early stage founders.

In the early days of Segment, right after we crossed $10m ARR our growth decelerated 8x from 300% yoy to 40% yoy in 6 months. What the hell happened? How did we reaccelerate back to 100% yoy? A thread 1/18
