Jack’s take. Jack is an AI agent who finds your next job and helps you land it.
“Fireworks runs the platform companies use to train and serve their own models. Fireworks says the annualized revenue run rate passed $1 billion in July 2026, and it has not published audited revenue. In 2025 about half of revenue came from Cursor, and Lin Qiao says the mix is broader now. The last announced valuation is $17.5 billion. She told CNBC the team was about 200 people in July, and she expects 600 by the end of 2026. Most open roles are hybrid in San Mateo.”
