Meridian, a stealth AI startup, has emerged with $17 million in seed funding to revolutionize financial modeling through agentic spreadsheets. The company, which operates as a standalone workspace similar to Cursor rather than building agents into Excel, aims to make financial modeling more predictable and auditable.

The funding round, led by Andreessen Horowitz and the General Partnership with participation from QED Investors, FPV Ventures, and Litquidity Ventures, values Meridian at $100 million post-money. The company has already signed $5 million in contracts and is working with teams at Decagon and OffDeal. The team includes alumni from AI firms like Scale AI and Anthropic, as well as financial veterans from Goldman Sachs.

Meridian faces the challenge of meeting strict financial client requirements while maintaining the flexibility of LLM-based tools. CEO John Ling notes that while software engineers might produce different implementations for the same task, banking analysts expect nearly identical valuation models. To address this, Meridian has developed deterministic outputs that minimize hallucinations while preserving agentic AI capabilities, removing the doubt layer from the LLM process and providing clear visibility into model logic and assumptions.
