YellowPad: Transforming Legal Workflows with Artificial Intelligence

Caro is the single source of truth for headcount that aligns finance, recruiting, and hiring leaders. As companies scale, the cost of the team (headcount) becomes their greatest expense (75%+ of spend for tech companies). Consequently, finance teams need to be vigilant about monitoring these costs. However, recruiting teams and hiring leaders are incentivized to hire quickly to ensure teams are sufficiently staffed so that they can deliver on their goals. This creates a tension between hiring velocity and spend management - a problem that exists in every company, resulting in hundreds of spreadsheets to reconcile data between the different teams and their different systems involved. Caro is backed by tier 1 investors: Accel and Lightspeed. We're proud to be trusted by leading tech companies like Affirm, Discord, and Intercom.
