At the start, a founder personally thanks every customer who converts. They reply to the review, ask what almost stopped the purchase, remember the order by name. By the time the same company has ten thousand customers, that same interaction has become a templated email and a support macro - and somewhere between those two points, the founder decided the shift was a sign of progress rather than a mistake.
The switch happens for operational reasons that don’t hold up strategically
Nobody sits down and decides to stop caring about individual customers. It happens because the systems built for scale - automated onboarding flows, ticket queues, standardized support scripts - are genuinely necessary once volume passes what any founder can handle personally. The problem is that those systems get applied uniformly, backward across the whole customer base, including the cohort that predates the need for them. A founder who once knew customer forty by name now treats that same customer identically to customer forty thousand, not because the relationship changed, but because the tooling did.
What the first hundred actually are
Customer ten thousand bought after reading reviews, comparing options, and seeing a case study that answered their objections before they raised them. Customer one bought with none of that reassurance available - no reviews existed yet, no case study, no comparison to a competitor’s known failure mode. That customer extended a kind of trust the company will never again be able to purchase at that price, because the proof that makes trust cheap now didn’t exist yet when they said yes.
That is precisely the asset a founder chases from an investor: capital committed before the evidence is complete, on the strength of the pitch and the person making it. Founders court investors accordingly - personal calls, regular updates, real gratitude. The first hundred customers gave something structurally similar and, in most companies, get none of the corresponding treatment once the growth curve takes off.
Where the neglect actually shows up
It rarely looks like neglect from the inside. It looks like a post-purchase email sequence that reads identically whether it’s customer three or customer thirty thousand. It looks like a founder who used to personally message new customers and quietly stopped once a support team existed to “handle” it. It looks like referral and review requests going out on a fixed day-fourteen schedule to everyone, instead of to the cohort that has actual standing to speak credibly about what the company was like before it worked.
What to actually do about it
Keep the list. Not a segment in the CRM - an actual, small, founder-visible list of the first hundred or so customers, maintained deliberately past the point where it stops being operationally necessary. Check in with that list periodically, not to sell them anything, but the way a founder checks in with an early investor: what’s working, what would you tell someone considering us, what haven’t we asked you that we should have. Ask that cohort for referrals and case studies only after that relationship exists, not on the same automated timer as everyone else. The next ten thousand customers will be convinced largely by what this first hundred say. Which one gets the personal attention should follow from that math, not from who is easiest to reach.
