SYNTHESIS

Elon Musk was unhappy with his kids' school. So around 2014 he hired Josh Dahn to build a new one inside SpaceX in California.

It was called Ad Astra, Latin for to the stars. There were no grades and no age-based classrooms.

The best part was a weekly session called Synthesis, where students played complex games to solve real problems together. Dahn and engineer Chrisman Frank, who came from the edtech app ClassDojo, decided those games were too good to keep locked inside one tiny school.

In 2020 they spun Synthesis out as its own company so any kid could play.

Synthesis was a subscription for parents. You paid a monthly fee, around $180, and your kid joined online sessions playing team strategy games with other kids.

The goal was to teach judgment, teamwork, and problem-solving. Things a normal worksheet cannot teach.

Later Synthesis pivoted to an AI math tutor kids use on their own. Parents still pay a subscription.

The customer was always the ambitious parent who wants more than the local school offers.

The original product was the online game sessions, where kids solved problems together in teams. The current flagship is Synthesis Tutor, an AI math tutor for young kids that adapts to how each child learns.

It walks students through math using voice and visuals. The company calls it a superhuman tutor.

Both products share the same goal. Make kids think, not just memorize.

Synthesis had one growth weapon most startups would kill for. Elon Musk.

The story that it grew out of Musk's private SpaceX school was catnip for the press and for parents. That got it endless free attention.

It leaned into an exclusive, word-of-mouth feel among tech-savvy families. Then it raised a community round on Wefunder, turning its own users into investors and evangelists.

Selling premium education to parents is a small market. $180 a month is a lot, so Synthesis was always going to be niche.

The bigger challenge came with the pivot to AI tutoring. Now it competes with Khan Academy and everyone else racing to build an AI tutor.

The Musk origin story gets you in the door. It does not teach a kid long division.

The product has to actually work, and public investor updates went quiet after December 2024.

Synthesis has raised about $17.5 million. A seed round in 2021 brought in roughly $4.6 million.

In April 2022 it raised $12 million led by Balaji Srinivasan and Replit founder Amjad Masad. O'Shaughnessy Ventures added money in 2023.

Synthesis also ran a community round on Wefunder, letting regular users buy in. The backers skew toward the crypto and tech-founder crowd, which fits its build-the-future vibe.
