Tobiko Data, the creator of popular open source projects SQLGlot and SQLMesh, has raised a $4.5 million seed funding round from Unusual Ventures and a $17.3 million Series A led by Theory Ventures with participation from 20Sales, Fivetran CEO George Fraser, Census CEO Boris Jabes, and MotherDuck CEO Jordan Tigani. Tomasz Tunguz, Founder of Theory Ventures, will join the Board as part of the investment. This brings the company’s total funding raised to $21.8 million.

Tobiko plans to use the funds to continue investing in SQLMesh and SQLGlot, in addition to its managed cloud and enterprise version, available today. SQLMesh allows data scientists and analysts to build data pipelines in SQL (with less involvement from a data engineer), automating the manual toil that typically comes with wrangling data to build pipelines. SQLGlot, a key component of SQLMesh, is an open source SQL parser, transpiler, and translator that currently supports 24 different SQL dialects.

Tobiko was founded by brothers Tyson and Toby Mao, and Iaroslav Zeigerman, industry veterans who have led data initiatives at Airbnb, Netflix, and Apple. Toby was previously senior staff engineer at Airbnb, where he led XP and Minerva, Airbnb’s metric platform; before that, he led the XP platform at Netflix, where he met Iaroslav, who was a senior software engineer on Netflix’s data team. Most recently, Iaroslav led AI/ML data engineering at Apple.

“Data transformation as it exists today is fundamentally broken. Other transformation products today don’t understand SQL; instead, they blindly execute scripts with no comprehension of the underlying changes,” said Tyson Mao, CEO and co-founder. “Not to mention that a single change in a query can affect billions of rows of data, and companies spend millions every year on unnecessary rebuilds of the warehouse when only a small precise change is needed. Tobiko eliminates redundant computations, which can become extremely costly.”
