Who exactly: segmentation and the beachhead market
The single necessary and sufficient condition for a business is a paying customer.
Not a product. Not a team. Not funding. A paying customer. So the first question is not what to build. It is who, exactly, will pay, and who among them will pay first.
Focus on end users, actual humans who will use the product, not vague companies. A company does not feel pain. A payroll specialist at a 40-person firm who redoes the same spreadsheet every month feels pain.
Two traps
The first trap is we sell to everyone. It sounds like ambition. It is the absence of a decision, and it makes every later step impossible: you cannot interview everyone, you cannot write a landing page for everyone, you cannot price for everyone.
The second trap is fun with spreadsheets. Founders build a beautiful segmentation matrix from desk research and never talk to a single person in any of the segments. The matrix is a list of hypotheses. Interviews are how you find out which row is real.
What makes a segment a market
A market segment is a group of customers who buy the same product, buy it the same way, and influence each other. If they do not talk to each other, word of mouth cannot work and you pay full price for every customer forever. If the three conditions are not met, you have not found a market yet. You have found a demographic. Keep segmenting.
- They buy the same product.
- They buy it the same way, through the same channel, with the same decision process.
- They influence each other. Word of mouth is possible.
Why a beachhead
A beachhead is a small market segment you can dominate first, then expand from. Amazon started with people buying books online. Facebook started with Harvard students. LinkedIn started with Bay Area conference attendees. None of those were the end goal. All of them were the place to win first.
The test I use: would you genuinely want to spend the next three years serving these customers every day? If the answer is no, pick another beachhead. You will be talking to them a lot.
How big should it be
Beachhead TAM is the annual revenue you would earn at 100% share of the beachhead. Too big and you cannot compete. Too small and it cannot fund the next step. A top-down estimate is enough for now: number of end users multiplied by annual revenue per user. Write the sources down. You will be asked.
FOUND's beachhead, and the two we did not pick
Candidate segments: recruiters at agencies, HR teams at scale-ups, and senior product managers looking for a next role. The founders knew agencies best. We picked the product managers anyway: they talked to each other constantly, they had a sharp, urgent job to be done, and Zurich was small enough to reach them in weeks. The beachhead was product managers in Zurich, 5+ years experience, seeking a leadership role.
From 500 product managers in the segment, our first ads and landing page reached 360 and fully vetted 100. A good ad-to-landing conversion is 5 to 10%. Ours was 11%, and that number came from the beachhead being narrow, not from clever copy.
Segmentation matrix and beachhead
Fill three segments. Use secondary research to fill the rows, then mark what is a guess. Then choose one and check the three conditions. Google and AI are fine for the rows. They are not fine for the choice.
| Segment name | End user (a specific human) | What they do today | Why they would buy | Do they talk to each other? | |
