Mintlify provides documentation and a knowledge layer intended for AI agents, positioning docs as operational infrastructure rather than static content. The company reports powering docs for more than 20,000 companies, including customers such as Microsoft, Anthropic, Coinbase, and PayPal, and reaching over 100 million people per year. Mintlify says that over 50% of traffic across its customer base is now from AI agents, which it uses to justify pivoting documentation toward agent-queryable, machine-readable knowledge. The firm frames its roadmap around building the “knowledge infrastructure” that keeps agent reasoning grounded and knowledge sources fresh and verifiable. The recent $45M Series B at a $500M valuation led by Andreessen Horowitz and Salesforce Ventures is intended to accelerate that work. No revenue, founding year, or location details were provided in the source material.

Mosaic builds AI-driven video editing agents and a platform called Canvas that aims to enable scalable, customizable video workflow automation. Canvas introduces a non-traditional interface designed for high-volume workflows, supports custom nodes for niche use cases, and integrates with existing media asset managers (MAMs) and non-linear editors (NLEs). The product is already in production with media and news customers and Mosaic highlights partnerships with TubeScience and News Corp; one customer reported tripling vertical video output during a pilot. Mosaic says Canvas can scale to handle volumes such as 8K videos per month and is positioned as infrastructure rather than a chat-based editor. The company plans to use its seed funding to add headcount in San Francisco and continue R&D on multimodal AI and agentic editing.
