Abacum is the leading Business Planning solution for finance teams to drive performance. By automating reporting, enabling collaboration, and simplifying planning and forecasting, we help finance teams shift from number crunching to driving strategic decisions.
Founded in 2020 by two former CFOs, we've grown into a general team of 100+ people across 30+ nationalities. Headquartered in New York, we have offices in Toronto and Barcelona. We're trusted by industry leaders such as Dish Networks, Strava, BetterUp, Kajabi, JG Wentworth, Abridge, Cortex, and hundreds more.
