First Customers (GTM)

What are the biggest mistakes founders make trying to land their first customers that I should avoid?

A starting point

The classic traps: building in secret for months then launching to crickets, pitching features instead of listening for the problem, and chasing volume when you have not closed a single deal by hand. Founders also over-value polite interest and under-value the awkward work of asking someone to actually pay. Start with the reverse of each mistake: talk to people early, sell before you finish building, and treat the first no as information, not rejection.

Why we picked it Eisenmann studied a large set of real startup post-mortems, so this talk turns 'no market need' from a cliche into concrete, memorable patterns you can actually watch out for. He is honest that the most common killer is building something before confirming enough people want it, which is exactly the trap that sinks the first-customer stage. Use it to recognize the shape of the mistakes early, while they are still cheap to fix.

Why Startups Fail (with Tom Eisenmann, Harvard Business School)

On YouTube (Harvard Innovation Labs) by Tom Eisenmann, Harvard Business School

The most common reason startups die is not competition or tech: it is building something without confirming real demand first.
Early false positives (friends, a few eager users) fool founders into scaling a product the wider market does not actually want.
Post-mortems repeat: the patterns are predictable, so you can spot them in your own venture before you have burned the runway.

Why we picked it This is the plainest, most credible list of the traps that keep founders from their first customers, written by the people who have watched thousands of startups try. It names the exact failure modes you are asking about: not knowing where your first users will come from, not talking to users, and prioritizing press and hiring over getting the product in front of real people. Treat it as a checklist of what to not do, not a formula for success.

Biggest mistakes first-time founders make

From Y Combinator Startup Library by Y Combinator (Michael Seibel)

The founders who struggle usually have no concrete answer for where their first users will actually come from, so decide that before you build.
Talking to users is the work, not a distraction from it: skipping real conversations is how you build something nobody asked for.
Chasing press, hiring, and polish before you have paying users is a way to feel busy while avoiding the hard part.

The Mom Test

From momtestbook.com by Rob Fitzpatrick ~130 pages

Talk about their life, not your idea.
Ask about specifics in the past, not opinions about the future.
'That's so cool, I'd totally buy it' is a compliment, not data, dig for commitment and evidence.
