In their words

In addition to being the CEO or the founder, you need to be the chief survival officer and do everything you can to survive until you find a lucky break where things come together, have an inflection point, and go after the next lucky break, repeatedly.

It's simple to do a startup: find a problem that people are willing to pay you for, and rinse and repeat. Very, very simple — but of course not easy.

This is my inverse Russian roulette pin, and what it means is the odds of your startup surviving 10 years is worse than inverse Russian roulette. Prove me wrong.

Quick answers

What was it like when Eldon Sprickerhoff started eSentire in 2001?

Cybersecurity was a blue ocean — only a handful of companies existed, not even that many in Canada. There was no YC or YouTube, he had no business acumen, and he learned by making mistakes. The catch with a blue ocean, he says, is that nobody knows why they should buy you, because there's nothing to compare you to.

Why did he write his book, Committed?

As an EIR and core mentor at the Rogers Cybersecure Catalyst accelerator, nine of every ten questions founders asked him were business questions, not tech — and he has no MBA, just a tech background and a Waterloo degree. He wrote the recurring answers down as an FAQ that grew to 55,000 words and became Committed, covering as many of his own mistakes as he could remember. He started writing in summer 2022, before ChatGPT was released.

What does he warn founders about venture debt?

A debt instrument doesn't dilute you, but venture-debt paperwork can carry a personal guarantee, and the common assurance that no one ever calls it is not the case — he says one group specializing in venture debt has been calling guarantees in over the last five years. If the company goes out of business, you and your co-founder are jointly and severally responsible for the debt, so do not go offside on your covenants.
