$177k one month after launch. My new stealth company is even growing faster than Cal AI. We’re looking to bring on a Head of Email Marketing to build out lifecycle marketing funnels. If interested, DM Me.

Twitter timeline yesterday: "Cal AI banned from app store" Twitter timeline today: "Cal AI back on app store" If you guys spent the amount of time you talk about Cal AI building your own companies, maybe you would see some results 😂

Working on a new project. This time I'm getting into hardware. I'm looking for an embedded systems engineer to design custom PCBs and work hands-on across hardware prototyping. Generous salary and equity. DM me.

Say what you want about Cal AI, but you can’t say we don’t push boundaries. The same risk-tolerate, fast-paced culture that may set us back a few days is the exact superpower that caused us to reach $50M ARR in 1.5 years. They will love you as an underdog and hate you as a victor.

Silicon Valley wants you to think this and that’s why you are going to focus on building your product for years before hitting the market. And then once you finally do, you realize all the time was wasted and no one wants it. Paid forms of marketing are key in all companies that aren’t inherently social and therefore do not have k-factor flywheels. Very surprised to hear this from one of the foremost investors in Uber, because Uber relied on paid marketing via incentives!

It's really interesting how so few people truly understand how distribution works. There is no magic sauce. If it's a sole-user experience, you just need to learn how CAC : LTV works and then how to operate social media platforms on both the organic and paid side. If it's a social experience, you need to learn how k-factor works (much harder). Stop doing stupid shit like throwing flyers out of airplanes.

There are two kinds of founders: Those who start with a bold idea and learn the business skills along the way, and those who already have the business instincts and are simply hunting for the right idea. Zach Yadegari is the latter. He’s been building all kinds of apps for years, from websites that let students access blocked games during school to alarm clocks that play motivational soundbites. When he met Henry Langmac at coding camp at 10, and they joined forces, that pace only accelerated. “We were going to just keep releasing new apps until we found one that really stood out and felt like it had real potential,” Yadegari says. “Then we’d double down and go all-in.” That app was Cal AI, an AI-powered calorie tracker and a 2026 Under 30 company. This week, the cofounders announced they sold the app to MyFitnessPal after scaling it to $30 million in revenue last year.

I wouldn’t have ever imagined how far Cal AI would come. Our North Star goal when starting the company was just to hit $50k / mo, and even that I felt was ambitious. Everything that has happened has been surreal. There were so many ups and downs, sleepless nights, and periods of uncertainty where I felt like everything was burning down, but through it all we kept pushing forward.

Cal AI has been acquired by MyFitnessPal 🚨 Henry and I started Cal AI as 17-year old high school students with one mission: make calorie tracking easier with AI. In just 18 months, we’ve helped millions of people lose millions of pounds. And we broke $50m in ARR along the way. We are at an incredible inflection point in history where ANYBODY can build a product that can improve lives and make millions. As founders, we get a lot of praise. The truth is that this would not have been possible without our incredible 30+ person team. We are so proud of what this team has accomplished, and are thankful to everyone that has been instrumental in Cal AI’s development and success. Cal AI will continue as a separate app from MyFitnessPal. The combined team will share resources to continue helping people achieve their fitness goals!

The school system really needs to change and it’s up to the entrepreneurs to do it. It doesn’t make sense that students should learn outdated information that is completely thrown out the window when they get their first job. Curriculums should be ever adapting. The latest innovations, such as AI, need to be immediately implemented. Each school should have a “CIO.” ALSO We need to really teach students to think from first principles when solving problems, NOT to memorize a list of solutions. I’m constantly APPALLED by the lack of critical thinking by other college students. I have to press into them for an ounce of logic in thought. These students aren’t dumb, they just aren’t taught how to assess problems. This should be one of the paramount problems we focus on as a society. If we fix education, future generations will fix EVERYTHING ELSE.
