Meridian

The AI-powered modeling layer for Excel

[Calvin Zhang @calvincbzhang]

New paper from @scale_AI & @MeridianAgent: SpreadsheetArena 📄

We evaluated 16 LLMs on end-to-end spreadsheet generation via 4,300+ blind pairwise votes.

Crucially, we move beyond scalar Elo ratings to decompose the latent preference signal into functional, structural, and stylistic components. 🧵

Very excited for us @a16z to have led the seed round for @MeridianAgent alongside @thegp (@phineasb), with participation from @FPVventures and @QEDInvestors.

Meridian is building an IDE designed for finance to bring AI superpowers directly into spreadsheets. The product automates repeatable modeling workflows in a way that conforms to a firm’s templates and standards, with deterministic, reviewable outputs and full traceability back to source data. Instead of producing black-box answers, Meridian is designed for high-stakes environments where every number must be verifiable.

@jhnling and his cofounders were widely regarded as top operators out of @scale_AI. We consistently heard that they set a “high bar within a high bar” and were “unstoppable forces on the team”, and they’ve hired a fantastic team with backgrounds in both finance and AI to pursue the opportunity. They also move fast and are already working with a top investment bank, private equity firms, and high growth startups.

If you live in Excel, Meridian is built for you. Very excited to partner with this team, and congratulations on the launch! @Daisy4ai

Meet Meridian: Turn Hours in Excel into Minutes
If you work in Excel, Meridian is built for you.

Meridian works with companies like Decagon, OffDeal, a top investment bank, and other financial institutions. We’re an AI-powered workspace that automates Excel modeling work with full traceability back to source data.

We raised $17 million in seed funding, co-led by @a16z and @TheGP to bring @MeridianAgent to more finance teams.
