This week on the startup to scaleup journey:
- Your best investor pitch is the one you'll never hear
Ask a DeepTech founder at Seed or Series A what they are most anxious about before a raise, and almost all of them point at the technology. Is the demonstration robust enough. Will the data survive a technical partner's scrutiny. Can we prove, beyond argument, that the science does what we say it does. So the weeks before a round pour into exactly that: the demo, the data room, the technical appendix that answers the question they are certain decides everything.
But they are answering the stated question, not the real one. Yes, the science matters. But an experienced early-stage investor is not, at the very beginning of this conversation, trying to satisfy themselves that the tech works. They have provisionally granted it, because backing that kind of bet is the entire reason their fund exists. What they are testing, first and hardest, is whether anyone will actually need the thing you are building once it does.
And they do not test that by asking you. They test it by asking your early adopters, in conversations you are not in, cannot hear, and cannot stage-manage. You will have pitched. It will have gone well, or seemed to. Then, after your meeting and well before any term sheet, the most consequential conversation of your raise takes place in a room you have just left...
This week on the startup to scaleup journey:
- DeepTech's long timelines, and the excuse they become
Every DeepTech founder learns to explain the timeline. The science is hard, the build is long, and the mainstream market may be years away. You get good at saying this, because it is true, and because the founders who cannot hold their nerve through extended timelines rarely make it. Patience, you are told, is the DeepTech virtue.
The founders who get caught out are not the impatient ones. They are the ones who let that patience become embedded in the company culture.
Because "our timelines are long" slowly becomes the answer to everything. The senior hire that should have taken three weeks drifts into its third month. The first real customer conversation waits until the product feels ready, and the product never quite feels ready. The raise starts late, because there is always one more result worth having in hand first. None of that is the science. It has simply borrowed the same excuse. And while you are being patient about the things that were never fixed, a competitor who saw you prove the market exists is moving faster on every one of them.
That is the trap. Your timeline is really two clocks running at once. One is the external clock: the physics, the regulatory approval, the slow build of market adoption, everything whose speed is set by someone other than you and that no amount of your urgency will move. The other is the internal clock: the decisions you make, the people you hire, the customers you prioritise, the round you run, everything whose speed is yours to set.
Most founders run the internal clock far slower than they think, mistaking a habit for a constraint. The trick is to run the internal clock much faster than feels natural, not only out of competitive necessity, but to be ready for that tipping point moment when the external clock suddenly accelerates...

- The founder skill investors test, but never name
What is an investor buying when they back your DeepTech startup through the early growth rounds?
Not the technology. By the time a company is raising these rounds, the technology is table stakes, proven enough to be interesting, unproven enough to be a bet. What they are really underwriting is a founder who can scale with the business. And scaling means one hard discipline above all others: steadily letting go of the hands-on work that carried the company to this point. Over the coming rounds the company now needs the founder to transition to a new role - a very different role to that needed at the start.
This is the companion question to one we asked in an earlier issue, which looked at the engineer-to-CEO transition from the inside, as an identity shift the founder has to live through. This week we are on the other side of the table. Because the same transition you experience as a private struggle, your investor is watching as a commercial signal. And they are reading it long before you think the test has started...

- Your company was revalued this quarter, and nobody told you
Ask a founder what their company is worth and they will tell you the price of their last round.
It is the number on the announcement. It is the number in the board pack. It is the number they carry around in their head, unchanged, until the next round moves it.
There is a problem with that. Somewhere in an office you have never visited, someone has already changed it.
And not just once. At every reporting date since the money landed, one or more of your investors has arrived at a fresh number for your company and sent it to people you have never met. You were not consulted. You were not told. In most cases you have no right to be.
This is not some subversive move by your investors. It is an accounting obligation and it is entirely routine. But it produces an asymmetry founders rarely think about. The people on the other side of your next negotiation have been quietly forming and recording a view of your value since the last round. You have been working from a figure you put out in a press release.
This critical metric, nearly always kept secret, is what conditions investor behaviour as the company progresses...
This week on the startup to scaleup journey:
- Venture debt: the loan instrument for founders who don't need it
Venture debt is having a moment, and the pitch is a seductive one.
Capital without dilution. Additional runway without another six months of investor meetings. To a founder just told the round will take longer and price lower than hoped, it sounds less like a financial instrument than a way out of a problem.
The market appears to agree. 2026 has produced some of the highest UK venture debt loan values since 2023, according to NatWest's analysis of PitchBook data. So the instinct is understandable. If debt is flowing, and debt does not dilute, why is anyone still selling equity?
Here is the question almost nobody asks first. When a lender advances several million pounds to a company with no profits, no hard assets and no certainty of surviving the next few years, what are they holding as security?
Not your technology. Not your revenue.
They are holding your investors.
Venture debt is not an alternative to equity. It is a bet on equity, and on the people already on your cap table writing another cheque. Everything follows from that: who can borrow, what the money can buy, and what happens when things go wrong.
Which is why the same data holds a second figure, far less widely quoted. For every 13 UK venture capital deals this year, roughly one venture debt deal was done.
The money is growing while the number of borrowers stays small. That is not a market opening up. It is a market concentrating around a particular kind of company.
The question is whether you are that kind of company, and the answer has remarkably little to do with how good your business is...

- The most expensive word in your pitch deck
Somewhere in the UK this week, a founder building something genuinely hard - a quantum computer, a new semiconductor process, a fusion reactor - is rewriting their pitch deck to sound more like an AI company.
You can hardly blame them. AI took 74% of all venture capital invested in the UK in the first half of 2026, some $12.6 billion of $17 billion, per Dealroom. Across Europe, PitchBook's Q2 European Venture Report puts AI at 60.2% of deal value, up from 37.8% last year. Numbers like these exert a gravitational pull on positioning. If three-quarters of the money is flowing to one theme, surely the rational move is to stand in the flow?
So, the temptation whispers: add the word. Reframe the roadmap. Let the algorithms take top billing and move the engineering to slide nine.
Our argument this week is that this instinct, understandable as it is, now points in exactly the wrong direction. The AI label has quietly repriced. What once functioned as a fast pass into investor meetings now routes you into the most scrutinised queue in venture. And beneath the headline, the data shows capital rotating hard into engineering-led sectors that carry no AI badge at all.
The founders reading the 74% as an instruction are misreading it. Here is what the number actually says...
