She managed product for Call of Duty. Now she builds quests that teach kids fractions. The throughline was attention all along.
Open Moonlight today and you will not find a meditation timer or another habit tracker begging for your streak. You will find a quest. A child picks a topic - say, an introduction to fractions - and within two minutes a parent has spun up a personalized adventure, handed over a link, and walked away. The kid earns stars. The lesson adapts. The report writes itself. Siran Jiang calls the goal simple enough to fit on a sticker: "Making learning magical, one quest at a time."
That is the company now. The road to it is the strange part. Moonlight started life as a productivity and biohacking app - focus quests, avatars, leaderboards, a play-money economy of "crescent coins" - built on research borrowed from behavioral scientists, neuroscientists and psychologists. The thesis underneath never moved: attention is the skill that builds every other skill. The packaging did. What began as a tool to train grown-up focus became an AI platform aimed at the people who have the least focus and the most curiosity - children.
Jiang founded the company in 2023 and raised a $150K seed round that June, led by the Entrepreneurs Roundtable Accelerator. Thirty-odd people, one stubborn idea, and a founder whose resume reads less like a ladder and more like a dare.
Most founders pick a lane. Jiang collected them. Out of Columbia - where she double-majored in Finance and Spanish and graduated Magna Cum Laude with a prize-winning economics thesis - she went to Wall Street. Analyst at Evercore. Then the private equity side, as an associate at Warburg Pincus. The kind of opening chapter that usually decides the rest of the book.
She closed it. Los Angeles came next, and corporate strategy at MGM Studios, the home of James Bond. Then a sharp turn into gaming: product management for Call of Duty at Activision Blizzard, one of the largest entertainment franchises on earth. Add a stint as Chief of Staff at Indify and venture scouting at Creator Partners, hunting for ideas in the creator economy. Finance taught her rigor. Film taught her story. Games taught her how to make a person want to come back tomorrow. Moonlight needed all three.
In between, she did the thing ambitious people do when they are not sure which door to walk through: she got into Harvard Business School and Stanford GSB, and chose Stanford. The MBA, from 2021 to 2023, was where the idea finally had room to become a company.
"How my first job on Wall Street still holds me back as a tech founder."
The title of one of her own essays, written on Medium under the handle @siran_moon. It is a rare thing - a founder publicly auditing the habits she had to unlearn. Banking rewards precision and permission. Building rewards speed and nerve. She writes about the gap between them.
Strip away the brand names and a pattern shows up. Jiang is the daughter of generations of teachers - her own mother has taught for more than a decade. Before she ever ran a company, she ran a side practice that says everything about what she values: more than twelve years tutoring college applicants, with a reported 100% success rate getting them into their top choices.
Born in China, she moved through schools in Colorado and Texas before Columbia and Stanford. She speaks Mandarin. The teaching instinct kept surfacing - in essays asking "Is homework broken?", in the patience to walk a nervous teenager through three applications at once, in the decision to point an AI not at productivity hacks for adults but at curiosity in kids. Moonlight is, in the most literal sense, the family business gone digital.
A parent configures a learning quest in under two minutes, tuned to the child's age and interests.
Audio-only or fully interactive. The child earns stars and achievements as the AI adapts the lesson.
Parents get progress reports and performance analytics - learning made visible.

* Illustrative interpretation based on her public career history, not company-reported figures.
The wager behind Moonlight is that the real childhood battle is not screen time. It is focus - the muscle that lets a kid stay with one hard idea long enough to fall in love with it. If Jiang is right, the company that wins education will not be the one that delivers the most content. It will be the one that makes paying attention feel like the best game in the room. She has spent four industries learning how to do exactly that.
