We just crossed $500M ARR and welcomed new investors to @ElevenLabs: BlackRock, Wellington, Nvidia, Santander, Jamie Foxx, Eva Longoria and more.

Natural, human-like communication will be critical to broad AI adoption - and these new investors help us accelerate that work.

"UK AI companies in the last quarter raised six billion pounds...3x what we did last year, more than the whole of... continental Europe combined".

@Jameswise, Chairman of the £500M @UKSovereignAI Fund I on the UK's AI future:

"We're working with some of the leading UK based and international venture funds and those relationships will be incredibly valuable for crowding in more money over time".

"Should you need the hundred million pound round, the billion pound round or even the ten billion pound round... all the other public finance bodies we've got are looking at you from day one".

"The UK needs a huge amount of capital to compete in AI. Luckily, we're going in the right direction... there is probably nowhere outside the US and China you can raise billion pound seed rounds like we're seeing here outside of the UK".

From James's appearance in April.

@lottsnomad This looks really awesome!

BREAKING: Sequoia and Lightspeed co-lead Europe's largest seed funding round with $1.1B at $5.1B post for ex-Deepmind David Silver's Ineffable Intelligence.

David is committing to giving away 100% of the money he makes from his Ineffable equity via Founders Pledge - the biggest pledge in their history and it is likely to amount to multiple billions.

King’s Cross has evolved into a true AI cluster. It's home to:

> Google DeepMind
> Meta’s AI teams
> Synthesia
> Wayve
> Isomorphic Labs
> Now OpenAI’s first permanent UK office (88,500 sq ft, capacity for 500+ people, opening 2027 - London will be OpenAI’s largest research hub outside the US) and
> Anthropic’s new 158,000 sq ft space (capacity for ~800 people, quadrupling its current London headcount).
> Scale AI also recently expanded here.

The Silicon Valley of Europe.

Introducing GPT-5.5

A new class of intelligence for real work and powering agents, built to understand complex goals, use tools, check its work, and carry more tasks through to completion. It marks a new way of getting computer work done.

Now available in ChatGPT and Codex.

[OpenAI Developers @OpenAIDevs]

Codex is now used by more than 4 million people every week.

That’s a lot of work getting done.

Thanks for building with us.

[Tibo @thsottiaux]

Happy Tuesday. Codex has hit 4M active users, adding over 1M users in less than two weeks. To celebrate we will reset the rate limits again in a few hours. Enjoy!

UK based Rivan Industries just raised a $34,000,000 Series A to scale Europe's largest synthetic gas plant.

CEO & Founder Harvey Hodd (@harveyhodd) discusses the growing viability of synthetic fuels to create a sustainable Earth:

"If we're to make life sustainable on Earth, we need to capture gigatons of carbon. To do that, we need a profitable mechanism".

"20% of the world's energy you can't electrify. So, we're going to have to create trillions of dollars of synthetic fuels at some point and we're going to have to do so very, very cheaply".

"The thing that's changed over the last few years that makes that a viable reality is that energy cost or electricity cost has plummeted".

"Suddenly for the first time in history you can get very, very, very cheap electrons you can use them for very energy intensive processes... anything where a large percentage of overall cost base is energy".

I'm now a Thiel Fellow!

Growing up in NYC, I became obsessed with geography and later Africa. I started my first company in Africa at 15.

Now, I've moved to Nigeria to build Africa's super-app. I wake up excited to work tirelessly on a single thing. More fun than college.

[Sovereign AI @UKSovereignAI]

This time, with AI, we're acting differently...

[Spiros Margaris @SpirosMargaris]

The UK is investing to secure its position in AI.

A new sovereign fund aims to support domestic startups and reduce reliance on foreign technology.

It reflects a broader trend. AI is becoming a matter of national strategy, not just innovation.

[Sovereign AI @UKSovereignAI]

We were delighted to celebrate the launch of Sovereign AI alongside the Office for Investment at the @LSEplc

Thank you to everyone who joined us - founders, investors, and ecosystem partners - to mark the moment.

Bring back the bell!🔔

[Matt Clifford @matthewclifford]

Tech sovereignty is so much bigger than AI. Congratulations to @harveyhodd and Rivan Industries - building synthetic natural gas right here in the UK!

(They're hiring for some excellent roles)

The UK is having its AI moment and nobody was tracking the founders building it.

So we built a directory.

Thread 🧵

AI Founders UK is the UK's first curated directory of AI founders.

https://t.co/ccFQ2MPiEL

170 verified founders. 107 companies. £13.5B raised.

We also publish a weekly newsletter every Tuesday.

Founder stories, funding moves, ecosystem signals, and opportunities for UK AI builders.
