Eighteen months ago, roughly 8% of start-ups were making it from Seed to Series A. Today, that number has collapsed to just 2%.
This isn’t a marginal dip; it’s a structural break.
Across the UK start-up ecosystem, founders are spending longer in rounds, burning more runway, and struggling to convert early traction into conviction-grade growth. The result is a growing bottleneck at Seed stage – one that’s stalling innovation, slowing job creation, and quietly eroding confidence in the next generation of high-growth companies.
At first glance, the explanation feels obvious: tighter capital, cautious investors and macro uncertainty.
Our ‘Bridging the Gap’ Report data suggests that funding conditions are only part of the story, and the real problem runs much deeper and sits within execution.
The hardest jump in the start-up journey just got harder
Pre-Seed and Seed are still relatively forgiving stages – early traction, founder energy, and a compelling vision can carry a business surprisingly far.
But the jump from Seed to Series A is a different story.
Series A investors aren’t backing potential anymore; they’re underwriting proof. Proof that growth is repeatable, that the business can scale beyond founder heroics and proof that capital will be deployed efficiently, not experimentally.
In our research with over 100 start-up and scale-up leaders, one pattern kept surfacing: Many start-ups believe they’re progressing, but the timelines tell a different story.
Almost a quarter of founders told us they’d been in their current funding round for over two years. That level of stagnation post-Seed is a massive red flag and signals not just investor hesitancy, but deeper questions around readiness to scale.
From “growth at all costs” to “execution under the microscope”
For years, start-ups were rewarded for speed, targeting multiple ICPs, running parallel GTM motions and aggressively hiring to achieve big top-line numbers. All for the sake of growth at all costs.
In 2026, that playbook no longer works. Today’s investors are asking harder questions much earlier:
- Who exactly is this business winning with, and why?
- Can growth happen without the founder closing every deal?
- Are CAC, retention, and payback improving or quietly deteriorating?
- Is this a system, or a set of heroic efforts holding things together?
Based on our research, execution risk has replaced funding access as the primary gating factor.
Founders are facing higher investor expectations, slower buyer decision-making, more competition (especially from AI-native start-ups) and pressure to demonstrate capital efficiency far earlier than ever before.
The bar hasn’t just moved, it’s moved forward in the journey.
Why start-ups are stalling, even when the product is good
When we asked founders what was blocking their funding progression, economic conditions topped the list. That’s understandable, and very real, but once you look beyond the headline answers, a different picture emerges.
The most persistent blockers weren’t ambition or ideas. They were execution gaps hiding in plain sight, such as:
- GTM ownership that never evolved beyond the CEO
- Hiring commercial leaders too early, too late, or without a clear mandate
- Over-reliance on one or two early customers to “prove” Product-Market Fit
- Strategy without operational structure – big goals, vague execution
- Metrics that told a revenue story, but not a repeatable one
In other words, the foundations weren’t strong enough to support scale. This is why many start-ups feel close to Series A, but never quite get there. The signals founders believe are compelling often aren’t the signals investors are looking for.
Graduation is no longer about traction; it’s about readiness
The uncomfortable truth is this: Early traction might get you noticed, but execution maturity gets you funded.
Graduation today requires more than revenue growth. It requires clear GTM ownership beyond the founder, evidence of repeatable customer acquisition and metrics that demonstrate efficiency, not just momentum.
Start-ups that fail to make this shift don’t necessarily fail outright. Many survive, and some even grow, but they will stall and get stuck between stages and will find themselves waiting for the market to change, instead of adapting to it.
The good news is that this crisis is fixable. Yes, the collapse in graduation rates is serious, but it isn’t inevitable.
Once you stop optimising for headlines and start building for durability and focus on the metrics that actually matter, you will break the pattern.
