Atominvest
“Can a modular, AI-native operating system replace the fragmented spreadsheet-and-fund-admin stack that runs private markets?”

The story
Atominvest is a UK-based vertical SaaS company (Atominvest Software Ltd, No. 12967871) building an operating system for private markets firms — investor management (fundraising, onboarding, e-subscriptions, portal, reporting) and portfolio management (data ingestion, analytics, valuations, ESG, fund accounting). Positioning has evolved toward AI-native workflows, evidenced by an MCP layer for LLM-powered portfolio queries. It is a workflow/data SaaS rather than an embedded finance platform — it does not hold or move client money and does not appear to embed payments, cards, lending, or BaaS.
