Artificial Intelligence is not magic. The technology is only
useful if it’s easy to understand.
The best AI products won’t be built from boxed solutions. Developers need
custom models and transparent tools, not just cloud services.
AI software needs better developer and user experience. This requires
hybrid skill sets and radical attention to detail.
If you ship it, you should own it. We believe in taking responsibility
for our software, and letting you do the same.
Technology should be accessible. We want to provide the most value with
open-source software. That’s why we’ve built spaCy
and our other tools and libraries.
We’re not your typical startup. We’re bootstrapped, independent and put
stability over moonshots.
In August 2021, we
sold 5% of Explosion to SignalFire for
$6 million. Employees are given a stake in Explosion using a
virtual share bonus program.
