From BitBalloon to Netlify
Mathias Biilmann and Christian Bach, both from Denmark, started Netlify in San Francisco in 2014 around BitBalloon, a tool for dropping a folder of static files into a browser and getting a live site. In 2015 they relaunched as Netlify, connected it to GitHub, GitLab and Bitbucket, and Biilmann coined 'Jamstack' to describe sites pre-built at deploy time and served from a CDN.
Workflow features that won developers
Every git push triggered an automatic build and an atomic deploy, and every pull request got its own Deploy Preview URL. Netlify Functions (2018) and Edge Functions (2022) added server-side code without separate cloud accounts.
Funding and acquisitions
Netlify raised about $212 million: a $12 million Series A led by Andreessen Horowitz (2017), a $30 million Series B led by Kleiner Perkins (2018), a $53 million Series C led by EQT Ventures (2020) and a $105 million Series D led by Bessemer Venture Partners at a $2 billion valuation (2021). It then bought FeaturePeek, OneGraph, Quirrel, Gatsby and Stackbit, and cut staff in late 2022 and mid-2023.
The $104,000 bill
In February 2024 a free-tier user received a roughly $104,000 bill after a traffic attack. The CEO said it would be waived, but the episode fuelled demands for hard spending caps.
The AI agent era
AI app builders changed Netlify's growth. Bolt.new users deployed 1 million sites between November 2024 and March 2025, and the developer count doubled from 5 million to 10 million by December 24, 2025. In 2026 Netlify launched prompt-to-production projects, 'Netlify for Agents' and a $20/month Pro plan with unlimited seats, saying about 40,000 people sign up each day. Netlify remains private and does not disclose revenue.
