Today is my last day leading @Codecademy after 12 years. @ryanbubinski and I went from a prototype we hacked together in 3 weeks… To a business with more than 50m users that we sold for $500m+. Here are a few things we learned turning a breakout product into a great company:

For @Codecademy 's first 4yrs, we were in the 📰 every wk. Those weeks, we made $0. The past 4 years, we've been out of the headlines. Now, we've raised $40m, our first raise in ~4yrs. How'd we go from the center of the hype cycle to the brink of bankruptcy and back? Read on...

Most startups die of self-inflicted wounds, not because of their competitors. Keep your head down and focus less on competitors and more on product market fit. Hire the right people and remember that the user is your customer, and your investors and journalists aren't.

Ignoring the hype: I find this one hard myself. Every day, one of your competitors is in the news or goes viral on Twitter. Don't pay attention. Your Twitter followers don't pay the bills. If someone *really* wants something you've built, they'll pay you for it.

We started @Codecademy in 2011. With software eating the world and few ways to learn to create it, we saw a huge opportunity. In YC, we built Codecademy as "the easiest way to learn to code." We posted it to HN as a Hail Mary before Demo Day and got 200,000 signups in 3 days.

We were off: the press loved it, we were on every 30 Under 30 list, won awards, and more. As a founder, all of this felt great...until we had to raise 💵 to stay alive. All the press clippings didn't add up to enough $ to demonstrate we'd built something people would pay for.

To go from a viral product to a lasting company, we had to focus on: - People: pay with passion when you can’t afford anything else. - Perseverance: this is your only edge at a startup. - Profitability: it’s hard to run a company if you run out of money! Let’s dig in…

As a first time CEO, I thought I needed to know everything, but our team said “we know you don’t have all the answers. We’re here to help you find them.” It’s OK not to know something, but it’s not OK to pretend you do. Your job is to hire people who know the things you don’t

Growing the team marks a transition from “building the machine” yourself to the CEO’s eventual job: “building the machine that builds the machine.” (per @jerrycolonna ) While we start companies to build products and write code, the job becomes all about the people very quickly

All startup problems are people problems. With every stumble, I resisted fixing it myself. Could I coach the team to do so? If not, it was time to find someone else. It’s counterintuitive to not do it yourself, but it’s the CEO’s job to fix the machine, not the problems

Founders turn into CEOs when they go from doing the thing they’re good at to *managing* people doing the things they haven’t done. Learning to do this means meeting a *lot* of great executives and asking them how they do their jobs, even if you aren’t interviewing them

Getting profitable gave us freedom. We saw competitors raise $100m+ at high valuations. We wondered if we were silly for building a *business* that made more than it spent and for raising less $ than we could have. Many of those companies are out of business or struggling today
