What Bluebook does

Bluebook is building AI agents for accounting firms to accelerate research, reconciliations and monthly closings. We allow professionals to serve 200 clients instead of just 20. With research time cut by 30% accountants can provide more strategic advice to help their clients thrive. The 30 leading firms in the Nordics already use Bluebook. The accounting industry faces a perfect storm: a massive CPA retirement wave (75% in the coming 15 years), increasing complexity from globalization and new regulations, and private equity consolidation driving productivity demands. LLMs enables software that can understand context, adapt to new scenarios, and handle complex accounting tasks with human-like reasoning - capabilities that traditional rule-based software lacks.
