Managing human capital is one of the most complex challenges in modern business: constantly shifting priorities, evolving skills, and siloed systems make optimization nearly impossible.
Mosaic is the first AI resource manager built to continuously plan and optimize how people and agent resources are utilized across an organization. The category is expanding rapidly, with 20–25% CAGR today and adjacent automation markets growing 40%+ annually.
Mosaic forecasts workload, revenue, and headcount, simulates staffing scenarios, and automatically adapts plans as reality changes- creating a self-optimizing workforce system at enterprise scale.
Mosaic ranked #813 on the 2026 Inc. 5000 Fastest Growing Companies in America ($454 in 2025, #226 in 2024, #23 in New York, #25 in software). Now, we're scaling to serve large enterprises that demand intelligent workforce orchestration at scale.
