Case Study: The Riverside Company streamlines early-stage underwriting with Mosaic

The Riverside Company cuts underwriting model build time to 15 minutes with Mosaic

The Riverside Company, a premier New York-based private equity firm, faced a challenge where its deal teams spent hours manually rebuilding legacy Excel models for each new investment opportunity. This process, which took between two to eight hours per model, limited comparability across deals and diverted time from higher-value analysis. The firm partnered with vendor Mosaic to transform its methodology into a repeatable operating framework.

Mosaic provided a standardized modeling environment that allowed Riverside's teams to generate initial underwriting models in approximately 15 minutes instead of several hours. This solution saved significant time, improved comparability across opportunities, and built a connected body of institutional knowledge. The measurable impact includes over 350,000 hours saved across firms using Mosaic and the creation of a more scalable underwriting process.
