It's 9 p.m. on a Tuesday.
A 31-year-old backend engineer in Austin opens her laptop after putting her kid to bed. She's been writing Python for seven years. She knows her job. She doesn't know whether she can pass the system design loop at Stripe, and she's tired of pretending otherwise. She logs into Formation.
Within minutes she's in a video call with a staff engineer from Airbnb who is, politely, taking her load balancer apart. There's a benchmark score waiting at the end. There's a plan for next week. There's no syllabus, because the syllabus rewrites itself every time she finishes a problem. This is what Formation does, every night, for hundreds of engineers who have decided that ambition without a coach is a slow leak.
The mentorship gap nobody priced.
Tech likes to tell itself a clean story: write good code, get good jobs. Anyone who has ever stared at a whiteboard while a stranger from Google asks them to design Twitter knows the story is incomplete. Mid-career engineers - especially those without the Stanford rolodex or the FAANG-friend network - keep hitting the same ceiling. They can ship. They can review. They cannot, on demand, perform.
Conventional bootcamps were built for the wrong audience. They teach you to code, not to interview at your level. LeetCode is a treadmill with no coach. Big interview prep courses are static; your weaknesses are not. Somewhere between those options, a few hundred thousand experienced engineers have been quietly under-compensated for years - which is, ironically, the kind of inefficiency tech is supposed to fix.
Sophie Novati had seen this movie before.
Novati studied computer science at Carnegie Mellon and spent the back half of the 2010s as a staff software engineer at Facebook and Nextdoor. She mentored junior engineers. She watched smart people stall. She noticed that the people who advanced often had something the others didn't - not raw talent, but a senior engineer in their corner who would tell them, plainly, what to fix. She decided that mentorship was a system, not a favor.
Formation launched in 2019 on a fairly cheeky premise: the people grading you in interviews work at the companies you want to join, so why not have them coach you first? In 2021, Andreessen Horowitz led a $4 million seed round to find out if that premise scaled. A Series A followed in 2023, taking the total to roughly $9 million. The check sizes are modest by software standards. The bet is not - that career mobility, for engineers, is a product problem.
An interview gym, with a coach who actually reads your tape.
Formation's program is part assessment engine, part human network. The platform continuously benchmarks fellows across algorithms, data structures and system design, then rewrites their study plan based on what just broke. Mentors - working engineers from Meta, Google, Stripe, Airbnb and Dropbox - run mock interviews, code reviews and behavioral drills. Recent cohorts added an AI-fluency track, because the bar at top companies shifted under everyone's feet and Formation, refreshingly, said so out loud.
Pricing is structured to align incentives in a way that tech rarely manages: tuition has historically been a percentage of base salary, capped at $25,000. If the fellow doesn't level up, Formation doesn't really win. Skeptics on Glassdoor have called the price tag steep. Alumni call it a rounding error against the comp bump.
Adaptive Benchmarks
AI-driven assessments that re-rank your weaknesses every week and quietly file them under "homework".
Mentor Network
1:1 sessions with engineers from the companies you're trying to join. They have, in fact, been in that room.
Mock Loops
Coding, system design, behavioral - run end-to-end, on the clock, with feedback you can act on by Monday.
Career Coaching
Resume work, narrative coaching, negotiation. The non-technical lift most engineers refuse to do alone.
A short history of getting people hired.
Formation by the year
The receipts, since you asked.
Numbers in education-adjacent businesses are notoriously slippery. Formation's are at least specific. Hundreds of placements, traceable to real employers; comp increases that, if accurate, dwarf the tuition; press from outlets that don't run pieces on small startups for fun. The skeptic's job here is to ask whether the program selects for engineers who would have leveled up anyway. The honest answer is: probably some. Also, probably not all.
Where Formation alumni end up
Mentorship as infrastructure, not luck.
Formation talks a lot about access. It is, in fairness, easy to talk about and hard to deliver. The company's stated mission - personalize the path to a great engineering career, and put senior mentorship in reach of people who don't already have it - sounds inoffensive until you notice how few companies actually try. Most upskilling businesses sell content. Formation sells a relationship with a coach who has been in the room you're trying to enter. That is a different product, with a different unit economics conversation, and it is the more honest one.
The diversity language on the site is real but understated. The clearer signal is the program design: long, structured, mentor-heavy, comp-linked. It selects for engineers who want to be measured, and rewards the ones who keep showing up.
The thing AI didn't kill.
For a year or two the consensus said AI would make interview prep obsolete. Then the bar at the best companies went up, not down. System design got harder. AI fluency became its own loop. The people who were getting hired weren't memorizing more LeetCode - they were thinking more clearly, in front of strangers, on tight clocks. That is exactly what Formation trains. The product is, conveniently, indexed to whatever the bar happens to be this quarter.
There is a larger argument lurking here, which Formation only sometimes makes out loud: the bottleneck on tech careers is not talent and never really was. It is feedback. Most engineers are starved for it. Formation is, essentially, a feedback factory with a placement record.
9 p.m. on a Tuesday, again.
Six months later, the same Austin engineer logs in. The benchmark scores are different. The mentor is a different one. The job offer she opens on her phone is from Stripe. The base is up sixty thousand dollars. The signing bonus pays the tuition with room to spare. She closes the laptop and goes to bed at a perfectly normal hour.
This is not magic. It is, more boringly, what happens when a company decides career growth is a product and ships it with the same rigor it would ship anything else. Formation is six years into that bet. It still looks early.
