How do I write cold emails and LinkedIn messages that founders actually get replies to?

The short answer

A cold message gets replied to when it is obviously written for one specific person about their specific situation, not blasted to a list. Keep it short, lead with a reason you are reaching out to them, make the ask tiny (a quick reaction, not a 30-minute demo), and cut every word about yourself you can. Personalization at scale is a myth for founders, so send fewer, sharper messages to people you actually researched.

Why we picked it This is the canonical short talk on winning your first users when you have no audience and no sales team. Alstromer (YC partner, former head of growth at Airbnb) makes the case that early on you do things that do not scale: you go where your users already gather, reach out directly, and talk to them one at a time. For a solo technical founder that is a relief, because it is closer to helping people in a community than to cold-call selling.

How to Get Your First Customers (Startup School)

On Y Combinator (YouTube) by Gustaf Alstromer About 25 minutes

  • Do things that do not scale at the start: hand-find your first users in the communities and forums where they already hang out.
  • The founder should be the one doing early sales, because nobody understands the product and the problem better than you.
  • Charge early and watch who actually says yes; a real customer is a much stronger signal than a free sign-up.

Why we picked it Jen Abel has coached over 300 early-stage founders through their first sales, so this is grounded in what actually happens when an operator turns founder and has to open the first conversations. The core move here reframes your worry: treat those first outreaches as research, not pitches, which is precisely how you tap your old network without it feeling like you are cashing in on the relationship. Audio, video, and a full transcript are all on the page, so pick whichever way you learn.

The ultimate guide to founder-led sales | Jen Abel (JJELLYFISH)

On Lenny's Podcast by Lenny Rachitsky with Jen Abel About 1 hour 16 minutes

  • Treat early sales conversations as customer discovery: you are learning whether the problem is real, which lets a former colleague engage without feeling sold to.
  • There is a repeatable structure to first calls, demos, and follow-ups, so warmth from your network is the opener, not the whole plan.
  • Founder-led selling is expected at this stage; your industry context is an asset when you lead with the problem instead of the product.

Why we picked it Welsh shows the exact two-step process he used to build a million-dollar pipeline from cold DMs: find people already talking about your problem, then send a short message that offers something before it asks for anything. It is a working template, not a theory of outreach, and it maps directly onto our answer's point about a tiny ask.

Why we picked it Braun's four-sentence formula (proof you did your homework, the specific problem you think they have, a sliver of social proof, a humble ask) is the clearest short structure we found for turning research into a message instead of a pitch.
