Write the memo before the deck
A clear memo forces the founder to explain the customer, market structure, wedge, traction and open questions in plain language. It exposes weak logic before design polish hides it.
Most seed founders start with a pitch deck. The deck is visual, it feels like progress and it produces something that can be shared. But a deck is a presentation tool, not a thinking tool. When you write a deck, you are making decisions about layout, font and slide order before you have made decisions about what you actually believe. The memo flips this sequence. It asks you to write out the argument in full: who the customer is, why they need this, what you have built, what you have learned and what you still do not know.
The discipline of plain language is unforgiving. Jargon survives in decks because it sounds authoritative. In a memo, jargon is exposed. If you cannot explain your wedge without resorting to buzzwords, the wedge is not yet clear enough. If you cannot articulate the next milestone without hedging, the plan is not yet concrete enough. The memo does not need to be long. Two pages of clear prose are worth more than a polished deck that relies on enthusiasm to bridge gaps in the argument.
Write the memo. Let it sit. Then read it as if you were the investor seeing this company for the first time. The gaps you notice are the gaps the investor will notice too.
The wedge and the market
A sharp wedge into a narrow segment is more credible than a large TAM. Investors at seed stage are not looking for a company that addresses a trillion-dollar market from day one. They are looking for a company that can dominate a small market first and then expand.
The best wedges are specific enough that the founder can describe the exact user, the exact problem and the exact moment that the product becomes indispensable. Marketplace platforms like Gumtree, which started with a narrow expat community in London needing flatshares and second-hand goods, demonstrate the principle: the starting point was narrow enough to concentrate supply and demand, build trust through shared community identity and create repeat behaviour before expanding to a broader market. The initial community was not a limitation. It was the mechanism that made the marketplace work when density was hardest to achieve.
When a founder presents a TAM slide as their opening argument, the investor's instinct is to ask: how do you win the whole market? The answer is almost always unclear at seed stage. When a founder presents a wedge, the investor's instinct is to ask: can you win this segment? That question is answerable. And if you can win a small segment, you have a credible foundation for expansion. If you cannot win even a narrow segment, the size of the market is irrelevant.
Seed readiness means being able to articulate the wedge clearly, explain why it works and describe the logical path from that wedge to a broader market.
Choose the right proof
Different companies need different proof. A marketplace may need liquidity density, a fintech may need trust and risk evidence, and B2B software may need workflow urgency and retention. Choosing the wrong metric to showcase is as damaging as having no metrics at all.
The mistake founders make is presenting the metrics that look best rather than the metrics that matter most. GMV looks impressive for a marketplace, but if match rates are low and repeat transactions are rare, GMV is noise. User growth looks impressive for a fintech, but if activation rates are low and churn is high, growth is just spending money to acquire users who leave. ARR looks impressive for a B2B SaaS company, but if it is concentrated in three customers who are not expanding, ARR is fragility disguised as traction.
Instead, match the proof to the type of company. For a marketplace, prove liquidity: time to first match, search failure rate, repeat transaction rate, supplier return rate. For a fintech, prove trust: activation rate, transaction frequency, retention over time, risk indicators. For B2B software, prove workflow urgency: how much time does the product save, how quickly do users adopt it, do they expand usage after the initial purchase, do they renew.
The right proof is the one that answers the question: does this product work for its intended user? If you cannot answer that question with data, you are not yet ready for seed. If you can, the rest of the narrative follows naturally.
Make the unresolved work explicit
Good seed investors do not expect everything to be solved. They do expect the founder to know which assumptions matter most and what the next six months must prove.
The instinct when fundraising is to present the strongest possible version of the company. But seed investors see hundreds of pitches, and they can tell the difference between a founder who has thought carefully about what they do not know and a founder who is hoping the investor will not ask. The former inspires confidence. The latter raises concern.
Being explicit about unresolved work does several things. It shows that you have actually thought about the business, not just the product. It demonstrates intellectual honesty, which is one of the strongest signals a founder can give. And it creates a framework for the next conversation: if you say that the next six months need to prove X, Y and Z, the investor can evaluate whether those are the right things to prove and can track your progress against your own milestones.
Do not bury the open questions. State them. Explain what you are doing to resolve them. Show that you have a hypothesis and a timeline. An investor who trusts that you will figure out the unknowns is more likely to invest than an investor who suspects you are ignoring them.
The fundraising narrative
Translating messy early learning into an investor story is a skill, and it is different from the skill of building a product. The narrative is not a sales pitch. It is a structured argument that connects what you have observed, what you have built, what you have learned and what you intend to do next.
The structure that works best at seed stage is: insight, wedge, evidence, sequence, ambition. Insight is what you have seen that others have missed. Wedge is the specific, narrow starting point where you can prove the insight. Evidence is the data that shows the wedge is working. Sequence is the logical path from here to the next stage. Ambition is the large outcome that becomes credible if the sequence is executed well.
Each of these elements needs to be concrete. An insight like "marketplaces are hard to build" is a truism, not an insight. An insight like "expat communities create enough implicit trust to bootstrap a classifieds marketplace before product-level trust features exist" is specific enough to be testable. A wedge like "B2B software for small businesses" is too broad. A wedge like "scheduling software for independent childcare providers" is narrow enough to dominate. Evidence like "we have users" is vague. Evidence like "seventy per cent of providers who complete onboarding post a schedule in the first week and forty per cent are still active after ninety days" is the kind of signal that makes an investor lean in.
The narrative does not need to be perfect. It needs to be honest, specific and sequenced. If you can walk an investor through the chain from insight to ambition and back it up with evidence, the round becomes much easier to close.
Connect ambition to sequence
The large outcome should be credible because the first wedge is precise. Seed readiness is the ability to show how a small, sharp start can compound into category infrastructure.
Many founders struggle with this because the instinct is to present the large ambition as if it is obvious. It is not obvious. The question an investor is asking is not whether the market is big. It is whether this specific team, starting from this specific point, with this specific advantage, can build something that becomes hard to displace.
The pattern seen in successful marketplaces is instructive. The starting point is a narrow community with a specific need, and the ambition is to become the default platform for a much broader market. The sequence that connects them is: prove the model in one community, expand to adjacent communities, expand across categories within those communities, replicate the model geographically, and monetise the liquidity that emerges. Each step is credible because the previous step has been proven. The large ambition is not a leap of faith. It is the logical endpoint of a series of executable steps.
Seed readiness means being able to draw this line. Not perfectly, not with certainty, but with enough logic and evidence that an investor can see how the first six months lead to the next milestone, how that milestone opens the next market and how the compounding effect of execution can build something that matters. The founder who can do this is not just pitching a product. They are demonstrating the strategic thinking that turns a small start into a large outcome.
