Why we picked it
A grounded take on the real risk sitting under your question: when one customer is half your revenue, losing them can halve the company. Lemkin is honest that concentration is dangerous but survivable, using examples like Twilio and Palantir's top-heavy revenue. Read it to size the stakes calmly instead of either panicking or ignoring them.
Why we picked it
A balanced look at the evidence: deep expertise speeds decisions and credibility, but a large share of billion dollar founders had little relevant background. It helps you weigh your specific situation instead of assuming you are unqualified. Read it to decide honestly whether to build now or spend time closing the gap first.

Why we picked it
Jason Lemkin is the investor on the other end of the email, walking through two real cold emails he actually funded and explaining exactly what made them work.
