Round Ready Academy — Lesson 3 of 11
Most founders at £1M+ ARR have built more than they realise, and documented less than they need to. This lesson is the candid version of that observation: the specific places where founders overweight what diligence does not reward, and under-document what it does.
You can read this lesson cold. You will get more out of it if you have already run the Round Readiness Diagnostic, because the diagnostic output will tell you which of the blind spots below you are currently carrying.
Diligence teams do not punish you for gaps they can see; they punish you for gaps they have to infer. A known weakness, documented and explained, is usually priced fairly. An unknown weakness, discovered by the partner, is usually priced conservatively — which is another way of saying "priced low".
The most common overweighting at £1M+ ARR is the belief that the product itself is the defensible asset. It is rarely the single most defensible asset, and it is almost never the one diligence spends the most time on.
Products get copied. Features get cloned. The genuinely defensible things are almost always organisational: the cohort data you have been collecting for three years, the customer relationships that generate expansion without a sales motion, the team composition that took you five hiring mistakes to arrive at, the culture that produces shipping cadence a competitor cannot replicate.
Founders who lead with "our product does X better" tend to lose the price argument. Founders who lead with "here is the compounding asset base that produces the product" tend to win it.
This is the single biggest diligence gap we see at Series A. Most founders have built more organisational capital than they have written down.
The fix is rarely "build new processes". It is "document the processes that already exist". Most Series A companies have a sales process; very few have it written down with stage definitions, conversion benchmarks, and qualification criteria. Most have an onboarding ritual; very few have a 30-60-90 plan by role. Most have a decision-making pattern; very few have it described in one page.
Two weeks of unglamorous documentation work, done honestly, can move a Series A pre-money materially. Diligence teams reward companies that can point at the page.
Revenue concentration is not a narrative problem to be spun. It is a diligence metric that will be calculated whether or not you present it. Every partner will ask for revenue by top-10 customer. Every partner will notice if the top-3 is more than 40% of ARR.
The right move is to get there first. Present the concentration figure, frame it honestly, and explain what you are doing to widen the base. "Our top-3 is 38% and declining — three quarters ago it was 52%, and the trajectory is driven by the following segment expansion" is a credible narrative. "We have great customers" is not.
A vertical SaaS at £2.1M ARR with 41% top-3 concentration presented this upfront in its first Series A meeting, with a cohort trajectory showing concentration falling 5 percentage points per quarter since the hire of a second AE. The partner memo later noted "founders demonstrated honest engagement with the concentration risk and a credible dilution path." The round closed in the top half of the sector range.
Not every piece of software is IP. Not every bit of proprietary tooling is protectable. Founders sometimes claim patent-worthy innovation where what they have is a well-executed but unprotected implementation.
The honest question is: would a competent engineering team, given six to nine months, be able to build a functional equivalent? If the answer is yes, it is not IP — it is execution advantage, which is still valuable but priced differently.
Three genuine categories of IP at Series A:
Everything else is technology capability, which belongs to Driver 4 (Technology and Innovation) and should be described that way. Lesson 10 covers in depth what specifically counts as collateral for IP-backed lending — a stricter test again.
Founders often lead with top-line growth and bury the retention numbers. Investors do the opposite. At Series A and B, retention is the first cohort-level metric they will ask about, and the answer is the single biggest determinant of whether the round prices at the top or the bottom of the range.
Three things to have ready, per segment:
| Metric | Why it matters | Series A bar | Series B bar |
|---|---|---|---|
| Gross logo retention | Churn signal; tests product-market fit depth | 85%+ | 90%+ |
| Net revenue retention | Expansion signal; tests land-and-expand motion | 100%+ best cohort | 120%+ average |
| Cohort payback curve | Capital efficiency signal; tests LTV/CAC claim | <24 months | <18 months |
If you cannot produce these per segment, for at least your last three cohorts, you are not ready for the Series A diligence deck. This is one of the single highest-leverage pieces of pre-round preparation.
The team slide is often a logo-free headshot collage, lightly captioned. Investors read it as an asset register of human capital. Every hire has a story: where they came from, what they left behind, what specific thing they were hired to do, and whether they have done it.
Diligence will ask about attrition — especially of senior hires in the last 18 months — and about key-person exposure. The right preparation is to have the answer before the question lands. If two senior hires have left, have the explanation ready. If one engineer is the single point of failure on a core system, have the redundancy plan ready.
Culture is the driver most dismissed as soft and most under-evidenced. It is also the driver that, when a diligence team sees it evidenced well, produces the clearest "this team is different" conclusion.
Evidencing culture is concrete. Glassdoor scores, eNPS, retention of early hires, documented operating rituals (weekly metrics reviews, shipping cadence, customer-contact norms), public commitments that have been kept. A well-evidenced culture slide in the diligence pack changes how a partner writes the IC memo.
The last blind spot is the most common: founders arrive at first partner meetings under-using the assets they have already built. A three-year customer cohort dataset is in the CRM — but has never been summarised. A strong NPS programme produces monthly reports — but the results are not in the deck. A Regulatory and Compliance position took 18 months to earn — but is mentioned in one bullet.
The exercise of building a Value Drivers Register is, at heart, an exercise in surfacing what you already have. Most Series A founders who run the full Opagio Method find they have more defensible assets than they had documented — and the round closes above the starting range because the diligence pack reflects that.
The common thread across these eight blind spots is not that founders are unprepared — it is that founders are prepared for the wrong kind of conversation. Decks are built for storytelling; diligence is built for inspection. The fix is not to build a better deck; it is to build a parallel evidence bundle organised by driver.
The Round Readiness Diagnostic is the fastest way to see, in twenty minutes, which of the twelve drivers your current evidence bundle under-documents.
A composite example of what "evidence-ready" looks like at £1.8M ARR, heading into first partner conversations:
None of this is glamorous. All of it materially changes how the IC memo gets written.
The fastest way to find out which of these eight blind spots is most relevant to your business is to run the Round Readiness Diagnostic. It scores you across the twelve drivers, surfaces which of the gaps above are present in your current evidence base, and tells you which of Lessons 4 through 11 is the highest-leverage next read.
Run the Round Readiness Diagnostic to surface which of the eight blind spots above is currently costing you the most in a diligence conversation. For readers who want to go deeper on individual drivers first, the Value Drivers Academy covers Customer Capital, Organisational Capital, Human Capital, and the other nine drivers in depth. Glossary entries include Organisational Capital, Human Capital, and Net Revenue Retention.
