Tutteo Limited

Who owns Flat? Flat is owned by Tutteo Limited, a private London company founded in 2015 by Pierre Rannou, Vincent Giersch, Corentin Gurtner, and Cyril Coutelier.

Is Tutteo a French company? The founders are French and the project began as a French student project, but Tutteo Limited is incorporated in England and headquartered in London, with a US subsidiary in Delaware.

What does Tutteo make? The Flat collaborative music notation editor, the Flat for Education classroom platform, and embeddable notation tools that integrate with Google and Microsoft products.

How many people use Flat? The Flat community passed five million users in 2020 and has continued to grow, concentrated in education.

The Flat project began in 2012 as a final-year student project by Pierre Rannou, Vincent Giersch, Corentin Gurtner, and Cyril Coutelier. The public beta launched in November 2014, and Tutteo Limited was incorporated in England and Wales in August 2015.

A seed round in 2015, led by angel investors Jean David Blanc of Allocine and Pierre Kosciusko-Morizet of PriceMinister, funded the first commercial push. That year also brought entry into the Google for Education partner program and integrations with Google Classroom and Drive, which seeded what became Flat for Education in 2016.

The company reached profitability in 2017 and has grown without further institutional fundraising, an unusual path in edtech. Community size passed five million users by 2020, and the team stayed deliberately small. The product line has since added embeddable notation and tablature tools for Google and Microsoft document suites, selling to schools, publishers, and platforms rather than only to individuals.

Tutteo is a small remote-first software company with minimal direct footprint. Its education pricing includes free tiers for schools in need, and the founders describe the mission as democratizing music composition.
