If you're a founder raising VC it's important to take references from portfolio companies who are not (yet) breakout superstars. It's as important to learn from founders who hit sudden headwinds, needed a critical bridge round etc and find out how the VC was during hard times.

Agent infra is here!
Infrastructure is always a function of the workload. With agent adoption taking off since Dec'25, we are now seeing a new infra stack emerging.
Wrote down my & Tobias's thoughts on what's happening below!

Yesterday we announced Jules, a plug-in home battery starting at just £199. It uses the same premium LFP cells as everyone else, but features a Fuse-designed PCB, IoT, firmware, enclosure, and digital twin. We priced it at 5X cheaper per kWh of storage than the rest of the market (when bundled with our 5-year energy tariff). Here’s how:
We’re the energy company. Because we see a property’s live consumption and wholesale energy prices, we build vastly better forecasts. Every piece of hardware we ship is also a trading asset. It draws power when costs are low and supports the grid when it’s congested - automatically, without the customer lifting a finger. That trading profit subsidises the hardware cost and lowers consumer energy bills.
Jules is the first of many. Our hardware roadmap includes:
1. Big Jules: A larger battery for bigger homes, businesses, and the US market.
2. Fuse EV Charger.
3. Fuse Heat Pump: Heating and cooling designed for harsh winters and summer heatwaves.
Right now, we optimise single devices against raw energy costs. Next, we will deploy an in-house, transformer-based AI model for full portfolio co-optimisation. Think of it as a superhuman energy trader that dictates when to toggle utility-scale solar, gas, storage, home batteries, EVs, and HVAC, co-optimising everything against user consumption and market prices. Ultimately, this brings us one step closer to true energy abundance.
Two things we will never compromise on:
Design: These live in people’s homes and should look beautiful.
Hardware/Software Harmony: One app. One system. No more juggling five OEM apps that don’t talk to each other.
We’re hiring electrical, mechanical, and embedded hardware engineers. If you’ve spent years building hardware for companies that sell it once and forget it, come build hardware that gets smarter every day it’s plugged in.

Now that we've cracked Navier-Stokes and flying cars, there is only one true, super-human technological challenge left - lowering British electricity bills.
And Fuse seem to have cracked it! An affordable home battery & solar system which means lower bills and more energy independence at home, and at scale more capacity on the grid.
Hi there Jules, another impressive release from @alanchanguk , @charlesorr and the phenomenal team @fuseenergy.
Meet Jules by Fuse Energy.
An intelligent energy system for your home. Plug in and autopilot does the rest.
It learns your habits, stores power, trades the excess and continuously lowers your bills.

In the age of agents, systems of record have never mattered more. They’ve also never been less prepared for what’s coming.
Today, we’re announcing @attio's hybrid architecture, with the controls of application software at the scale of infrastructure.
To agents, Attio looks like a database, queryable in SQL - a language they're RL’d on. Unlike a database, the business logic, policies, and compliance sit behind the query.
This makes all of Attio’s data accessible by agents in the most powerful and flexible syntax. It gives GTM teams an order of magnitude more value from their time, with the full power of agents working across the entire customer lifecycle.
A new shape of software is here.

Well deserved recognition for @duvoai alongside the likes of Lawhive Wordsmith and Lio. Great to share this alongsie the $32M funding round from @balderton @IndexVentures @CredoVentures et al
We're honored to be named to the #Disruptors60 Class of 2026, curated by @GreenfieldVC at @TechCrunch Disrupt.
Our mission is raising the GDP of every employee, with one platform where people and AI agents run a company's operations together.
Thank you to our team, and to the customers and partners who helped us get here.
See the full class in the comments.

Excited to announce @balderton leading a $32M round in @duvoai . Getting AI agents to work reliably across the enterprise remains incredibly difficult. Duvo's unique ability is in how it uses AI to capture how work actually happens, then automate these processes in the same integrated system. This is only possible with the deep operational experience of the founder Tomáš who previously founded three companies including Rohlik, the leading online grocer. tech.eu/2026/10/14/from-rohl…

We've raised $32M in Series A funding to become the one platform enterprises run their operations on. 🚀
Led by @balderton, with participation from @IndexVentures, @northzoneVC and @CredoVentures, this brings our total funding to $48M and fuels our global expansion.
McKinsey sizes the long-term potential of generative AI at $4.4 trillion a year in added productivity. Most of it sits in the same place: every enterprise has hidden money trapped in broken processes, disconnected systems and manual work.
We're building the Enterprise Execution OS to release it. One platform where people and AI agents run operations together. We map how work actually happens, improve it, and automate it across existing systems. In weeks, not years.
And we've already delivered over $100M in annualized impact across dozens of enterprises.
Our mission is simple: raise the GDP of every employee. Unlock every business's working intelligence and empower people to create more value.
A huge thank you to our customers, investors, partners and the entire Duvo team who got us here.
The next chapter starts now. And we're just getting started. 🌎

@UnsettledGreg who is now CTO at Fuse joined us from a top hedge fund before Fuse, who had a 6 month non-compete, during that time he was not allowed to work at any official capacity, he got so bored he built a VR app that made a grand total of $600 in revenue.
If Greg was allowed to join earlier, Fuse would have been much more valuable today, energy costs would be even lower, and we would have been 1 step closer to energy abundance.
This is a great initiative by the UK government that makes the labour market more competitive, reducing the friction to build in Britain.

With this, we at @PointNineCap are the only firm left that stubbornly refuses to raise a larger fund. 😄🤔
(Not trying to put us into the same league as @usv and @benchmark with this comment!)
A thesis should take you somewhere new.
Ours began with the possibilities of the open internet. Today, it reaches across AI, energy, financial markets, and the physical world.
We’re evolving USV alongside it, with $900M in new funds to lead more rounds, back founders for longer, and support the scale of their ambitions.
@mignano on the next chapter of USV.

Jane Street about to become the world’s leading seed fund.
Quant firms are hiring idea guys, not quants
I've been skeptical about the whole - software is commoditized, ideas are the moat argument
But I've seen first hand the best quant and technical firms in the world hire thinkers, liberal arts grads, and generalists
I predict the trend accelerates

Law was one of the most obvious early verticals for LLMs: expensive labor, lots of text, document-heavy workflows, and customers paying $000s per seat.
GPT-4 (2023) was an inflection point for legal AI, & Harvey and Legora have shown how big that category can become.
That inflection point took longer for accounting, looks like it happened around o3 (2025).
AI has advanced enough now that accounting should be a great vertical for agents. The work seems particularly well-suited to AI: they use checklists, outputs are verifiable, and work is done by juniors and reviewed by seniors. That maps almost perfectly to AI doing the work and humans reviewing exceptions.
Per the research below (great work!), 18 months ago the best models were still below the average accountant on these tasks, but today the newest models outperform junior accountants.
There’s still a lot of work to do. Long-horizon, end-to-end accounting workflows are far from solved, and will be a massive unlock... but the trajectory is very clear.

Revealed: Nu Holdings has ended talks about a takeover of Monzo, the British neobank, which would have valued it in the region of £8bn-£10bn, just days after my report of discussions between the two companies triggered a sell-off in the New York-listed digital lender’s shares.

A lot in here I agree with:
- The public discussion seems to be mostly on AI hypotheticals. But there are serious and present opportunities and challenges facing the UK today.
- AI capabilities are hard power in the same way our military, energy and infrastructure are, and should be treated as such.
- While Brits should have access to the best services in the world wherever they’re built, we must have more of these capabilities here at home as well to ensure resilience and leverage.
The @UKSovereignAI Unit was set-up with much of this in mind - kind of David to give us a mention, but we’re only a small part of the solution.

Some quick ( and free! ) wins here for the Government to look at to support British researchers and engineers.

The case for generalist VCs...
In the AI-doomer argument, broad multidisciplinary thinkers like @sapinker have suggested the "kill-us-all" scenarios are preposterous. The AI researchers, that are most negatively outspoken, say that their voice should count more, because they are closest to AI and know what it can do.
Everyone watching this debate should read about Tetlock's work (see below). The generalists (foxes) and much better predictors than the specialists (hedgehogs) who are to close to the problem to accurately predict broader implications.
So "no points" for the "we know more" argument. In fact, it works against you.
