This guide covers how to present research to investors the way founders actually need it: with the framework, the common mistakes, and the evidence to back the work.
Most founders present research to investors in a way that inadvertently signals they have not done it carefully. The signals are subtle: round numbers with no methodology, competitor tables that list features without mentioning switching costs, and market size figures from research firms with no bottoms-up corroboration. Investors who have run their own diligence on the space will notice. Investors who have not will notice the absence of specificity.
Research presented well demonstrates analytical rigor, intellectual honesty, and awareness of what you do not know. Those three qualities are more valuable to an investor than a confident narrative that turns out to be built on optimistic assumptions.
Present market size with methodology, not just a number
The standard market size slide shows a TAM figure cited from a research report and a percentage that, if captured, would produce a large company. This format tells the investor nothing except that you found a large TAM and know how to run a simple percentage calculation.
Replace the research firm citation with a bottoms-up estimate. Show the buyer count (sourced from Census Bureau or LinkedIn data), the price per buyer (sourced from your customer interviews), and the implied market size. Show the SAM as a subset of the TAM with specific filters applied (geography, company size, industry). Show the SOM as your Year 3 or Year 5 revenue target, calculated as a penetration rate of the SAM.
This format demonstrates that you understand the structure of the market rather than the size of the category. Investors can challenge individual assumptions in a bottoms-up model. They cannot challenge a research firm headline without doing their own research, which means the conversation stays at the level of methodology rather than conclusion.
Acknowledge competitive threats honestly
The most common investor objection during the competitive analysis discussion is: "What happens if Salesforce adds this feature?" Most founders deflect this question rather than engaging with it. "We have a two-year head start" or "They are not focused on our segment" are deflections that signal the founder has not thought carefully about the scenario.
An honest answer engages the scenario: "If Salesforce adds this feature in 18 months, we lose the segment of buyers who are evaluating both Salesforce and us for their CRM. That segment is approximately 30 percent of our pipeline today. The remaining 70 percent are buyers who are not in the Salesforce ecosystem and are specifically looking for a point solution. Our defensibility strategy is to own that 70 percent deeply before the ecosystem players prioritize it."
This answer is more credible than a deflection because it names the threat, quantifies its impact, and describes a strategy for surviving it. Investors are not looking for a startup with no competitive threats. They are looking for a founder who understands the competitive landscape clearly enough to navigate it.
Present customer findings as evidence, not testimonials
Customer testimonials ("our customers love the product" or "our beta users said it is 10x better than what they were using before") are not evidence. They are marketing. Evidence is specific, behavioral, and sourced.
"Five of our first eight customers reported in structured interviews that the current solution fails in a specific way that costs their teams approximately 8 hours per month in manual correction work. At median salary for the role ($78,000 annually according to BLS 2024 data), that is $240 of unproductive labor per month per customer. Our product eliminates that failure mode." This is evidence. It is specific, it is sourced, and it is quantified.
The format of evidence presentation signals whether a founder approaches the business analytically or anecdotally. Analytical founders find patterns in customer data and express them quantitatively. Anecdotal founders collect positive quotes and present them as representative.
State your key assumptions and the evidence for each
The most credible section of any research-heavy investor presentation is a slide that says: "Here are the three assumptions our model depends on, the evidence we have for each one, and our confidence level in that evidence."
This format is counterintuitive. Most founders hide uncertain assumptions. Stating them explicitly seems like inviting scrutiny. In practice, it does the opposite. Investors who see a founder clearly articulate the two or three things that could make the model wrong, with honest evidence levels, trust the rest of the presentation more. The implicit message is: this founder is not trying to sell me. They are trying to tell me the truth about the business.
If you cannot state your three highest-risk assumptions and the evidence for each, that is itself a signal: there are assumptions in the model you have not yet tested.
A worked example: the research slide that earns a follow-up
The slide is 30 seconds of talking. It has three lines and one chart. Line one: "We interviewed 38 outpatient mental health practice managers across our two beachhead states between February and April. 27 had spreadsheet workflows for scheduling, 11 used SimplePractice, and the average dissatisfaction score on the existing tool was 6.2 out of 10." Line two: "We benchmarked 9 comparable vertical SaaS pricing pages and 4 horizontal incumbents; the $1,500 to $3,500 ACV band corresponds to practices of our target size; we priced at $2,400 ACV midpoint." Line three: "The riskiest assumption is that practices will switch from SimplePractice for the workflow advantage; the kill criterion is fewer than 4 of the next 25 demos converting to paid trial within 14 days." One chart: the 38-interview synthesis showing the top 3 workflow pains with frequency counts. That is the slide. The investor asks "how did you reach those 38?" The answer is the next slide.
The contrast is the slide that does not earn a follow-up: "We did extensive customer research and found strong demand." No numbers, no method, no kill criterion. The investor moves on because there is nothing to push on.
What investors check after the slide
The first check is sample composition. A founder who interviewed 38 friends-of-friends is not in the same league as a founder who interviewed 38 from a cold list with a defined screen. The follow-up is almost always "Tell me how you found them." A clean answer names a sourcing method: a community membership directory, a state licensing board lookup, a cold-list from a procured database. The narrowness of the screen is the signal.
The second check is what the founder believes. After 38 interviews, the founder should have updated at least one assumption from the original brief. If nothing changed, either the brief was already perfect (unlikely) or the interviews were confirmation exercises. The right answer to "what surprised you?" reveals the actual learning. The Lean Startup tradition calls this validated learning: research that changes a belief is more useful than research that confirms one.
The third check is the kill criterion follow-through. The slide named a threshold. The investor will ask "What if you hit it?" The acceptable answers are limited: re-pitch the wedge, change the price band, narrow the ICP, or stop. Founders who say "we’ll iterate based on signal" are signaling that the kill criterion was decorative. Founders who say "the next test would be X with a Y threshold" are signaling that they have already thought about the second decision.
The structural alternative: a one-page memo
Decks lose the argument at the seams. A one-page memo holds the argument together because the reader sees the whole shape at once. Bill Gurley’s pieces on memos and Bezos’s six-page memo culture point to the same observation: the format forces clarity. For pitch follow-ups, a single page of structured prose with three exhibits beats a 20-slide deck in almost every case. First Round Review’s pitch-deck archive is full of decks that read like memos: structured headings, numbers in the body, exhibits in the appendix.
The work that produces a defensible memo is the same work that produces a defensible slide: stating the evidence, the method, and the threshold at which the answer changes. Verdikt’s methodology ships every verdict in exactly this shape. The cover page is the memo. The exhibits are the citations. The reader sees the recommendation, the kill criterion, and the source-tier mix in 30 seconds, and the entire defense is one click away. That is what "research that earns a follow-up" actually looks like at the document level.
