Activity from announced rounds
Activity in this selectionmapleblock-8ea1edb8
Andreessen Horowitz, also known as a16z, is a venture investment firm. Its own investment announcements connect the firm to companies including Highstock.
Recorded funding activity
The recorded activity spans TypeSafe AI’s typed decisions for software workflows, Vesta’s AI-supported mortgage origination and Arena’s model evaluation. The history also links many other company financings under the firm’s name. Named programs such as Speedrun maintain their own activity pages rather than being treated as interchangeable with every firm-level investment.
