The wallet you trust with your keys is made by specific people at a specific company on specific money. All of that is public, and we have gathered it in one place — with links, so that every statement can be checked against something other than our word.
Legally the app is published by Rainbow Studio, Inc. — that is how the company is listed in the App Store. The product is a self-custody wallet: the keys are created on your device and the company does not have them. That is not a marketing claim but a property of the architecture, and it can be checked: the app's source code is fully open, which for wallets is the exception rather than the rule.
Before Rainbow the same team made Balance, a personal finance app and one of the first to try to show blockchain accounts in plain language. It did not take off, but it set the approach that later became Rainbow's defining trait: clarity first, features second.
The core of the Balance team founded a new company with a narrower task — a mobile Ethereum wallet an ordinary person could use. The first public version appeared in the App Store the same year.
The lead investor was Seven Seven Six, the fund of Reddit co-founder Alexis Ohanian. The round also included Thirty-Five Ventures (the fund of basketball player Kevin Durant and Rich Kleiman), Dom Hofmann's Bloom Investment Holdings, and Y Combinator. The round had actually closed back in October 2021 and was announced in February 2022.
On 5 February 2026 the Rainbow Foundation distributed 150 million RNBW to people who had accumulated points in the app. From that day the wallet had a token of its own — and with it everything we take apart on this site.
All three are still on the project, and that shows not on an "about us" page but in the code: their accounts are among the most active in the app's repository.
Started doing contract design work for Microsoft while still at school and joined Stripe at seventeen. Before Rainbow he was among the founders of Balance. On his GitHub profile he describes himself as "a designer who codes a little" — which is not false modesty: he has over four hundred commits in the app.
A software engineer by training. Before crypto she wrote trading tools for equity derivatives and recommendation algorithms for eBay. The most active contributor to the Rainbow repository: more than two thousand three hundred commits, twice as many as anyone else.
Worked on computer design and websites from an early age, dropped out of college to work as an engineer at several consumer-facing startups. Second by commit count in the repository. The most public of the three: he keeps a Farcaster account where he regularly comments on both the token and the product.
A list of founders says little about a product. A list of the people who actually land changes says much more. It is open, and here is the top of it by commit count in the app's main repository.
| Who | Commits | Known for, from their open profile |
|---|---|---|
| Jin Chung | 2,302 | co-founder, chief technology officer |
| Michael Demarais | 1,290 | co-founder |
| Bruno Barbieri | 828 | engineer, on the project since its early years |
| Skylar Barrera | 745 | engineer |
| Michał Osadnik | 622 | researcher, contributor to open-source projects |
| Christian Baroni | 452 | co-founder, chief executive |
| Matthew Wall | 310 | engineer |
| Wojciech Stanisz | 289 | engineer, Software Mansion |
What stands out here. Several people on the list work at Software Mansion, a Polish development studio known for its React Native libraries. So part of the work is done by a contractor, not only by in-house staff. That is normal practice, but worth knowing: it explains why names keep appearing in the repository that are on no list of employees.
The data was obtained by querying GitHub's public interface while this page was being prepared. What the team is changing in the code today is in the live feed on the Pulse page.
The token was issued not by the company but by a separate entity, the Rainbow Foundation. That split is typical: the product company and the token's steward are legally not the same person. For a holder the practical meaning is that their obligations differ, and promises from one side do not bind the other.
What can be checked beyond statements: the movement of tokens between the project's addresses is fully visible on the blockchain. Who refills the reward reserve, how much was bought on the market and how much came from the treasury — all of it is laid out on the Flows diagram, with addresses and amounts.
At the time of the 2022 round, more than twenty hires were reported. There is no current figure in open sources, and we are not going to invent one.
Rainbow is a private company and publishes no accounts. The 0.85% swap fee is known, the swap volume is not.
The cap table after the 2022 round was never disclosed. The participants in the round are known, their stakes are not.
Allocations in the staking contract are signed by one address — that much is visible in the contract itself. Who controls it does not follow from the blockchain.
Details about the founders and their backgrounds come from public material about the company and from their own GitHub profiles. The funding round comes from TechCrunch, Decrypt and The Block reports of February 2022. Commit counts, the app rating and the publisher were taken by direct queries to GitHub and Apple while this page was being prepared. The full list of checked links with dates is on the Sources page.
