Abacum is a financial planning and analysis platform built for mid-market and high-growth companies, particularly software and recurring-revenue businesses, that positions itself as AI-native rather than a spreadsheet replacement with AI bolted on. It integrates with hundreds of source systems, including ERPs, CRMs, HR and payroll tools, and data warehouses, to consolidate financial and operational data automatically, then supports three-statement modeling, driver-based forecasting, headcount and workforce planning, budgeting with department collaboration, and board and management reporting. Abacum emphasizes workflow: business partners in each department can review and adjust their own numbers within guardrails set by finance, reducing the back-and-forth of collecting inputs by email. Its AI layer generates report summaries, runs variance analysis, and offers recommendations, and the company states that customer financial data is not used to train its models or third-party language models. Abacum raised a Series B in 2025 to expand the platform and reported tripling revenue in the prior year. It is aimed at finance teams that want faster planning cycles and self-service for stakeholders without moving to a heavy enterprise system. Abacum is sold as a paid subscription priced by company size, modules, and integrations.
