Tallia raises €4 million seed to bring AI research and review to tax firms

London-based Tallia, formerly Revax, raised a €4 million ($4.5 million) seed round co-led by Outward VC and ICAEW to expand its AI research and drafting platform for tax and accountancy firms. The platform uses a custom retrieval system to tie AI answers to legislation, regulatory guidance and case law, and adds review workflows for senior staff. Tallia says it produces a fully cited first draft in about 30 seconds and saves teams five hours per fee earner each week.
