Interesting. AI will in effect increase both supply and demand for formal methods. You need them more, but you also have tools that make them cheaper. blog.janestreet.com/formal-m…

As well as incredible examples of entrepreneurship and innovation, it's worth remembering that the US Government was the first customer of both SpaceX and Palantir ( and in Palantir's case, one of the first investors too ). Both have been hugely positive for the US economy and their geopolitical position. There will be many positive announcements this week from my colleagues at DSIT on backing British AI start-ups, so it's worth remembering the size of the prize if we get it right. Government procurement isn't about picking winners, but supporting innovation and providing better public services. But back when SpaceX and Palantir were starting up and getting US Govt support - the UK couldn't have procured from a local start-up ( EU frameworks would have prevented them ) and even if we wanted too, the Govt didn't prioritise working with new technologies - but went with 'safe bets' with legacy companies for institutions like the NHS and Post Office....look where that got us. Thankfully, if belatedly, with the introduction of the BBB, NSSIF & the Procurement Act under the Conservatives, and expansion of the BBB and set-up of SovAI under this Government, I'm much more positive about our ability to start and scale similarly important, international winners going forward.

There are already 19,780 jobs live on the free jobs portal we just launched for start-ups based in the UK & Europe! There's no doubt AI is creating more jobs, but they will be different. In the era of the PC, and the internet, it was the people who jumped in and worked out how to get the best from these new technologies that benefitted the most - the same will be true in the AI era ( of people, as well as countries ). So do check out some of the roles in these mostly AI-first companies, great places to get experience or build an entrepreneurial career.

SaaS (per seat) revenue is better than transactional revenue. Usage based revenue is better than SaaS revenue. But transactional revenue = usage-based revenue. Am I the only VC who sees the contradiction here?

For over twenty years, @balderton has backed British & European entrepreneurs to build breakout technology companies. And there has never been a better time to do it. More people than ever are interested in founding companies, in joining start-ups, and in taking on some of the biggest challenges of our time with technology, from energy to health, defence to finance, building from here to win globally. And AI is making it easier than ever to get going. But there's a big gap with this positive movement, and the general coverage of the tech sector here, one which often suggests you can't or shouldn't try to start a business. Today we've launched a campaign to help change that. It is a public celebration of some of the founders driving the frontiers of tech, and a digital portal providing support to potential founders and access to 1,000s of open roles at start-ups. Yes there are challenges, and there always will be. But that didn't stop some of the founders that went before. We hope this helps nudge the conversation, and inspires a few more people to take the risk.

AI data centre electricity demand rose by 17% in 2025; nearly six times faster than overall global electricity growth. By 2030, AI-specific demand is projected to triple. There is no AI race without an energy race underneath it. China understands this clearly. They are building solar, wind, nuclear, coal, gas. All of it, simultaneously, at enormous scale. Meanwhile, much of the West still treats energy infrastructure as something to ration, delay, or optimise around scarcity. The countries that win in the AI era are the ones with the most power.

Why would any founder stay in the UK if you did this? Absolutely everything would push you to start, scale and list your business in the US. I don’t think Wes realises the biggest competitive advantage the UK has over California today is capital gains tax. Do this and say goodbye to any hope of reversing the stagnation.
Wes Streeting has this morning set out his tax plans - specifically bringing capital gains tax into line with income tax He says that the current system is unfair because it penalises work Higher or additional rate taxpayers will pay 24% on gains in the current financial year. Streeting said that the rates should mirror income tax bands - so 40% for higher rate taxpayers and 45% for additional rate taxpayers He says that the approach could raise £12billion a year Streeting said: “A member of my family is a cleaner in Lancashire. She pays a higher tax rate on her salary than her landlord pays for the growing value of the home she lives in. She slogs her guts out, he puts in far less effort, yet the state rewards him more than her. And we wonder why people are angry. “The system is penalising work. It’s not fair and it’s bad for our economy. We need a wealth tax that works. A pound made from simply owning assets should not be taxed less than a pound made from a hard day's work. We can do it in a way that is pro-growth, pro-entrepreneur and pro-work.”

The UK is already seeing the benefits of being an AI hub. But we’re not doing a good enough job of explaining the opportunity ahead. I wrote for @thetimes today on being an ambitious nation again - and the need to fight the AI doomers. We had similar opportunities in the internet era, but failed to seize on them. We can’t miss again.

Great to see @OpenAI double-down again on the UK with the acquisition of Tomoro to build out their $4B deployment company. Founded in Edinburgh & London with a presence in Manchester and Glasgow, worth checking out their open positions as I imagine they're about to expand alot!

17 investments in 3 months. All Fund III 💙 @e2mindset Conviction built over the past year All under @arinozkula's watch Launched our €100M Fund III in January. Most funds take a breath after raising. We didn’t. Some call it spray and pray. Not sure which part is doing the work. 9 bridging to SF (all AI) 5 Turkish mobile gaming 3 outside thesis because great founders don’t always fit neatly into one Looks chaotic from the outside. Feels obvious from here. Opening our SF office soon (South Park) Punching above our weight. Trying to become the default bridge between this region and SF.

I really hate this post, mostly because I think it’s true and a sad commentary on the current state of market. Herd behavior overwhelmingly driving decisions.

It's pretty insane how different running a company has been over the last three months. Claude code CLI is now the command interface for everything. Everything is connected and accessible via MCPs. Software is bespoke and instant. This moment feels far far more important than the world waking up to gpt3.5.

What excuse are OpenAI going to find to block this?
anthropic fucking killed it with this. so many people will start using claude. new feature lets you import your *entire* memory from chatGPT, Gemini etc into Claude so it *instantly* knows everything about you. no more reminding claude who you are. the best fucking part is it takes literally 60s: - copy and paste the below prompt into your alternative AI (eg chatgpt) - paste answer into claude’s “memory” settings and… you’re done. - Claude immediately picks up from the last conversation you had with it in chatgpt! the opportunity cost to switch to anthropic just went to zero - their app is currently #1 in the app store

Huge congrats to @wayve_ai on some big technical & commercial milestones. As Alex sets out - this is the boldest approach of any autonomous software lab. It’s not going to be easy, but being contrarian & right is what Alex does. Started in the UK, winning everywhere.
Another major milestone in @wayve_ai's history. Proud to say we’ve secured $1.5 billion Series D investment at $8.6 billion valuation. We started a decade ago with a contrarian technical thesis: that self-driving is an AI problem, and Embodied AI will enable autonomy to scale without rules, HD-maps and using mass-produced hardware. Now we're entering commercialisation, we're taking a contrarian commercial strategy too, selecting the business model with the largest opportunity to scale. We're not selling our own cars, which limits scale to one brand. We're not operating our own fleets, which limits autonomy to city-by-city expansion. We're licensing autonomy to any vehicle, anywhere. This new business model is only possible now because we've built a general purpose AI driver, which is flexible to work with any vehicle architecture and proven to drive all around the world. This unlocks a high margin software licensing model, which we're now excited to be deploying with global partners with the strength of this new funding round. Thank you to our new and returning financial investors for backing our vision all the way: @EclipseVentures, @balderton, @SoftBank, @OTPPinfo, @BaillieGifford, @BritishBBank, @IcehouseVenture and @Schroders among other global institutional investors. We're deepening our partnerships with @Microsoft and @nvidia to build and deploy Embodied AI at global scale, and with @Uber, who are announcing supervised robotaxi trials in 10 cities around the world, starting with London this year. To top it off, three top-10 global automakers across Europe, Japan and USA are backing and believing in our technology for consumer vehicles and robotaxis: @MercedesBenz, @Nissan and @Stellantis. I’ve always believed that our end-to-end AI approach would lead the way in autonomy. This latest investment and the endorsement that comes with it make me believe that the industry is also now converging on that idea too. What's next? We have a busy next few years of commercial delivery: supervised robotaxi trials around the world in 2026 and consumer vehicle sales from 2027. Thank you to the incredible Wayve team for making this all possible. Check out all details here: wayve.ai/press/series-d/
