Transition Ventures

🌍 For founders building a legacy that matters 🌍

[Transition Ventures @TransitionVC]

We grabbed a mic and asked our Physical AI hackers the questions on everyone’s mind 🧐

Our favourite mic-drop moment: “an idiot in motion outpaces someone smart but doesn’t move fast enough”. As for five-year plans, from the front page of Forbes to ringing the bell for an IPO - the room was not lacking ambition.

So fun co-hosting with Reasoning Project, @NEA and @microagi. @sama or @elonmusk - who would you pick? 👇

Congratulations to @OLIXComputing on today's $312m Series B announcement.

We've been lucky to work with @jamesdacombe and the team at Olix since their first venture round, and we are thrilled to deepen the partnership as part of this round.

Olix is building a truly generational company, and they’re hiring across the UK and US https://t.co/So09HfGTEZ.

We are excited to announce OLIX's $312m Series B.

OLIX's mission is to build the infrastructure for frontier AI. Instead of forcing a single chip to do everything, we build specialised silicon and an optical network to connect it, unrolling models across racks like an assembly line. A different answer to the industry's supply chain constraints, built on components available at scale today.

Alongside the round, we have appointed Professor Nick McKeown to our board of directors. Nick is one of the defining figures of modern networking and co-invented software-defined networking, OpenFlow and P4. He is Professor Emeritus of Computer Science and Electrical Engineering at Stanford University and winner of the 2025 Marconi Prize. He co-founded several companies, including Nicira, acquired by VMware, and Barefoot Networks, acquired by Intel, where he went on to lead the company's networking business.

We have also appointed Matt Briers as Chief Financial Officer. Matt was the CFO of Wise for nine years, joining in 2015 from Google when the company had around 500,000 customers and was loss-making through taking it public in a 2021 direct listing on the London Stock Exchange. Wise’s direct listing was the first by a technology company in London and the exchange's largest technology listing, valuing Wise at £8.75 billion, approximately $12 billion. He built the finance function that carried Wise from private company to the public markets while it remained profitable throughout.

Congratulations @reinpk and the rest of the team at Revoy! We're excited to be a part of the journey 🚀

[Peter Reinhardt @reinpk]

Announcing @Revoy’s $27M Series A

Diesel is expensive. But long-haul EV semis are even more expensive! Today we’re launching the United States’ first hybrid electric, cost-competitive long-haul freight network.

You don’t see it on your credit card statement, but the average American spends $1,270/year on long-haul freight. Diesel prices at the pump are outrageous today: rising on both international price shocks and increasing domestic shale oil costs. And pure EV semis are somehow even more expensive to operate. We need a better solution, and Ian Rust @semiautonomy figured it out. Revoy’s unique powered converter dolly lets us drop diesel usage by 95% and efficiently replace it with low-cost electricity.

After two years of demonstrations and iterative improvements, we’re now taking the unique Revoy vehicle that we design and manufacture, and launching our hybrid-electric freight network with a select set of carriers. Shippers can reduce diesel consumption immediately on Revoy’s network without having to convince legacy carriers to convert their fleets, and without any investment in new infrastructure or equipment.

We’re starting in the Pacific Northwest, with additional lanes planned.

With its second fund, London-based @TransitionVC is building on its initial focus on early-stage climate tech to back #AI infrastructure, energy, robotics and industrial systems.

We have raised over $150m to back the founders building what comes next.

The AI buildout and geopolitical pressures have made it undeniable that progress within planetary boundaries runs on atoms: energy, materials, infrastructure. The polluting, extractive, wasteful systems of the old world are giving way, and the companies rebuilding the physical world are scaling faster than ever.

@OLIXComputing is going after compute energy bottlenecks and just hit a $1bn valuation. @UpwayShop has put 200,000 refurbished e-bikes on the road, growing revenue 30x. @Seneca_Systems is fighting wildfires with autonomous drones, and raised a $60m first round.

The most ambitious founders want to build a company that matters, one that drives human progress for generations to come. They mold atoms, not just bits. Full-stack by necessity, principled by design, built to outlast them. The work is harder than traditional software, but the prize is exponentially bigger: reinventing the foundations of human prosperity.

We built Transition for these founders. Fund II lets us back more, from day one.

If you're building a legacy that matters, let’s chat!

We face an urgent shortage of reliable, high-density, base load power driven by electrification and the boom in demand for AI compute. Nuclear is one of the few clean, scalable options, but decades of complexity and regulatory friction have prevented meaningful deployment ⚡️

@Applied_Atomics solves this by developing and operating vertically integrated small modular nuclear plants, using proven light-water reactor technology to deliver clean electricity directly to hyperscalers and industrial sites.

Very excited for Transition Ventures to co-lead their latest $8.3m funding round and join Ben Kellie, Paul Keutelian and the Applied Atomics team on this journey!

We met @kunalsinha a couple years back when he was leading Glencore’s global recycling business. It quickly became clear that nobody had a better understanding of how the metals industry works, and how we can change it. When Kunal teamed up with Prof. Xiao Su and Dr. Johannes Elbert to start Valor, we knew we had to partner with them from day one.

Critical minerals sit at the heart of electrification, AI infrastructure and advanced manufacturing. But the way we refine them today is incredibly inefficient and polluting - and existing refining capacity is heavily centered in China. For Europe and the US, this has created a growing strategic vulnerability.

Valor is building a completely new approach to refining. Their novel electrochemical process can recover valuable metals such as gold, copper and rare earth elements from mixed feedstocks with 90% lower emissions and resource use, making it possible to build a new generation of cleaner and more flexible refining plants.

We are incredibly excited for the journey ahead with Kunal, Xiao, Johannes and our friends at Zero Infinity Partners!

[David Helgason @davidhelgason]

Extremely proud of being part of the @OLIXComputing journey with @jamesdacombe.

Keep an eye out of this quiet kid... I am certain that James will turn out to be one of the greatest founders of this generation.

Today, I'm excited to share the launch of @Seneca_Systems. Seneca's mission is end the wildfire threat across 500 million acres in the US and allied nations by 2035.

115 million Americans live with fire risk. Fire costs our nation ~$1 trillion annually. It destroys our most precious wild spaces and natural capital. And for those of us who call the American West our home, this is personal.

We must face this head on. It is time that we bring firefighters the next-generation tools that heroes deserve. Seneca is building the modern fire arsenal for the highest risk period in our history.

Our first product is an autonomous, AI-powered, rapid response fire suppression drone system.

We are proud to be backed with $60 million led by @caffeinatedcap and @convectivecap with participation from @firstround , @TransitionVC, @DCVC, @offlineventures, and others.

There is no question that fire risk is growing. But we must innovate to be resilient. This is not a battle we can lose.

Many thanks to the amazing Seneca team. Proud to be in the fight with you all. @nhfoley @billclerico @adrianaoun @johnclarkemills, @DrLoriMM, Chief Rick Balentine.

[Transition Ventures @TransitionVC]

It is really hot outside..... 🔥🥵

Read @mona_alsubaei's post about the need for personal cooling

[Mona @mona_alsubaei]

Read our post about personal cooling and adaptation @TransitionVC 🧊🔥

https://t.co/j6To2F28IL

I went to Hajj in June—a spiritual experience of a lifetime. But it was so hot. It has been so hot everywhere lately. Even the Olympics are feeling it.

Cooling spaces with AC isn’t efficient and isn't enough; we need to focus on cooling people first.

Personal cooling tech is essential, especially for outdoor workers and vulnerable groups. I’d love to connect with founders, doctors, scientists, and engineers working on this!
