How to Get Your First Customers
From Y Combinator
Tactical, un-glamorous advice for landing your first customers by hand — no ads, no virality, just the moves that actually work early on.
What this video covers
Gustaf Alströmer explains why early-stage founders must handle sales personally rather than outsourcing to sales reps or relying on passive marketing. He breaks down the cold outreach process: writing concise 6–8 sentence plain-text emails, running founder-led demos, tracking pipeline conversion math, and insisting on upfront payment instead of free trials. While directed at venture-backed software startups selling to other tech businesses, the cold emailing tactics and funnel tracking rules translate directly to any B2B service or consulting business hunting for initial clients.
Best for: B2B service providers and software businesses seeking their first 10 paying clients; Founders doing hands-on, outbound prospecting; Not applicable to B2C brick-and-mortar retail businesses; Not applicable to businesses relying purely on inbound ad channels at scale

Key points
- 01:32 Startups only take off because founders manually recruit early users; growth does not happen automatically from product quality alone
- 04:32 Sales is one of the easiest skills for a startup founder to learn quickly
- 06:44 Cold outbound sales emails perform best when capped at 6 to 8 sentences
- 12:33 Approximately 95% of prospective buyers are not early adopters and should be filtered out early
- 14:04 If users are not paying money for your offering, they are not real customers and you do not have a viable business
- 14:58 Money-back guarantees and contract cancellation opt-outs convert B2B buyers better than unpaid trials
- 16:05 Securing 2 paying customers typically requires roughly 500 outbound outreach attempts
- 18:03 Closing 5 paying customers from a batch of only 10 leads is statistically unrealistic in cold outbound sales
