Abacum

Abacum is an AI-native Financial Planning & Analysis (FP&A) platform designed to automate data trust, model maintenance, and reporting. It connects actuals, assumptions, and plans in one governed workspace, enabling finance teams to provide trusted answers quickly while decisions are still being made. The platform uses a layered intelligence stack—Context Intelligence, Modelling Intelligence, and Narrative Intelligence—to handle data cleansing, anomaly detection, formula building, version control, variance analysis, and AI-generated summaries. With AI Spaces, users can generate dashboards from natural language prompts or pre-built templates, allowing stakeholders to self-serve reports without burdening finance. Abacum replaces disconnected spreadsheets and brittle models with a unified environment where scenarios stay comparable, owners stay aligned on one plan, and changes propagate without breaking the logic. It integrates with existing source systems and supports driver-based planning, multi-entity consolidation, and real-time collaboration. The result is a 10x faster reporting and forecasting cycle, with a typical reduction of 8 days in the close process. Companies like PostHog and others use Abacum to keep finance lean while scaling operations.
