Treeline Raises Series A from Andreessen Horowitz to Build AI-Native Replacement for Legacy Corporate IT

Treeline, a startup developing an artificial intelligence and software-first alternative to legacy corporate IT infrastructure, has raised a Series A funding round led by Andreessen Horowitz, according to Fortune. The company, founded by Peter Doyle, is building enterprise software that replaces traditional IT management layers with AI-driven systems capable of handling device provisioning, access management, and support workflows without the complexity of legacy platforms from vendors like ServiceNow, Microsoft, and Salesforce. The pitch targets the substantial budget that large organizations spend maintaining and customizing enterprise software stacks that were designed before the current generation of AI capabilities existed. Treeline argues that rebuilding these systems from scratch with AI at the core eliminates years of accumulated technical debt and reduces the headcount required for IT operations. Andreessen Horowitz has made several investments in AI-first enterprise software companies that are attempting to displace incumbent vendors. The firm has argued publicly that AI enables startups to compress enterprise sales cycles by demonstrating faster implementation and lower total cost of ownership compared to established players. Treeline did not disclose the size of the Series A. The company is targeting mid-market and enterprise customers with complex IT environments who are frustrated by the cost and pace of customizing existing platforms. The company enters a competitive market. Startups including Rippling, Okta, and newer entrants have been chasing the same IT consolidation opportunity for years, though Treeline's founders argue that the current AI capabilities represent a genuinely new architecture rather than an incremental improvement.
