Why we picked it

- 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.

Before you have any customer stories, your own founder story is the only pitch you have, and this piece shows you how to use it. It walks through defining who suffers most from the problem, framing the cost of that problem in money, and structuring a pitch that makes buying obvious. For a founder who has never sold, it turns the first ten conversations from awkward into deliberate.

Validation in B2B bleeds straight into early sales, and this answers the real questions founders hit when they start selling to first buyers. It covers who to target, how to run those first deals founder-led, and when a pilot is enough proof to keep going. Practical grounding for the messy stretch between 'a buyer said yes on a call' and 'a buyer signed.'

Steli Efti built Close by doing founder sales the hard way, and here he answers the blunt questions founders actually ask about early selling and pricing. His central point matters for your first ten: charge more than feels comfortable, because underpricing hides whether people really want it. Short, practical, and free of jargon.

- A cold email must instantly answer who you are and why you picked them.

This is the rare cold email piece written by someone who has actually sent thousands of them (Steli Efti built Close, a sales CRM, on the back of founder-led outreach). It gives you 15 real templates with the subject line, the body, and the reasoning for when to use each, so you can see the moving parts instead of copying blind. It is honest that a template is a starting point, not a magic phrase: the personalization you add is what earns the reply.
From
Close
by Steli Efti
- Keep it short and answer three questions fast: who are you, what do you want, and why this person specifically.
- End with one clear, low-friction call to action, and plan your follow-ups before you send the first email.
- Templates save time but only work once you layer in real, specific personalization; a copy-paste blast reads like one.

This breaks down how Superhuman ran one-to-one onboarding and what founders should copy when they have only a handful of users. It gives your first ten a reason to stay, not just sign up.
