replace the email waitlist with calls
get on a call with every early user, hand-pick the first 50 and build what they ask for. a call gets you the attention an email no longer does.
the play
Stop waiting for an email to activate people. Get every early user on a call, one to one or in small groups. Set them up on the spot and write down what they ask for. Then build that.
what happened
| company | the hands-on move | result |
|---|---|---|
| Superhuman | every new user had to do a 30-minute 1:1 video onboarding to get in. early calls ran much longer | its product-market fit score, the share of users who’d be “very disappointed” without it, went from 22% to 58% as it focused on its keenest users and built what they asked for |
| Airbnb | Brian Chesky and Joe Gebbia went door to door to their New York hosts and photographed the homes themselves | revenue doubled after the better photos |
The 58% matters because of Sean Ellis’s benchmark: product-market fit needs at least 40% of users saying they’d be “very disappointed” without the product.
At YC they call the Stripe version of this the “Collison installation”, Paul Graham wrote. When someone agreed to try Stripe, the founders would say “Right then, give me your laptop” and set them up on the spot.
why it works
| lever | what it does |
|---|---|
| the call lands | a calendar invite with a person on the other end gets attended |
| you see where they get stuck | half an hour watching a user beats a month of dashboards |
| setup on the spot | the user leaves the call already using it, with their data in |
| you hear the requests first-hand | the features that 25 of your first 50 ask for are the roadmap |
| it doesn’t have to scale yet | Superhuman went from founders doing calls to dedicated onboarding specialists later |
from my calls
instead of moving to more hands off channels… you should move to more hands on channels of onboarding.
just manually identify 50 people who love using this feed.
A team lost most of its email waitlist. Their invites landed in Gmail’s “updates” tab and the codes that did get through were being resold. Their plan was more automation. I told them to go the other way:
| move | detail |
|---|---|
| group onboarding calls | two or three a week. invite people in, set them up live |
| hand-pick the first 50 | the people who actually love the feed, chosen by you |
| build what 25 of the 50 ask for | half your best users asking for the same thing is a signal |
| an hour each with the top 10 | sit with your ten best users one to one |
there is no way you can land emails in inbox. it’s incredibly hard these days.
cost vs payoff
| what | |
|---|---|
| cost | founder hours. every user is a call |
| cost | slower top-of-funnel growth while you do it |
| payoff | users who leave the call set up and active |
| payoff | a roadmap written by your best users |
| payoff | Superhuman’s PMF score went from 22% to 58% while it built what its keenest users asked for |
how to steal it
| crypto app | consumer app | |
|---|---|---|
| the call | a group call or Telegram voice chat where you walk people through wallet setup and the first trade or deposit | a 1:1 or small group video call to set up the account and first use |
| who gets in | hand-picked from the waitlist, onchain history or your community | hand-picked from the waitlist by fit |
| what to capture | where they get stuck, what they ask for, who they’d invite | where they get stuck, what they ask for |
| the cadence | two or three group calls a week | same |
| measure | activation on the call, week-one retention, requests per user | same |
Run it like this:
- Kill the “we’ll email you when you’re in” step. Send a call link instead.
- Pick the first 50 by hand.
- Write down every request. Build what half of them ask for.
- Spend an hour each with your top 10.
- Hire someone to run the calls only once you know what a good call looks like.
watch-outs
| watch-out | what to do |
|---|---|
| it eats founder time | cap it. group calls two or three times a week, 1:1 only for the top 10 |
| invite codes get resold | tie the code to a call slot or a named person |
| building for the loudest user | count requests. build what half of the 50 ask for |
| no plan to stop | decide what self-serve onboarding looks like once the calls stop teaching you anything new |
