The product

Ingest. Standardize. Analyze.

Every board pack, compliance report, and management account becomes a structured, queryable view of your portfolio.

01

Ingest every document

Board packs, management accounts, compliance reports, earnings transcripts — PDFs, decks, spreadsheets, emails. Drop them in or have portcos send them through. Expect unstructured, messy data — our AI makes sense of it.

  • Extracts every metric, not just headline KPIs
  • Handles messy formats, detects multipliers (e.g. 000s), and extrapolates data (e.g. monthly from quarterly)
  • Audit trail on every number — flags conflicts when sources disagree

Standardize across your portfolio

Every portco reports differently. Compose any metric from each company's own line items using formulas — then compare like-for-like across the portfolio.

  • Formulas, not just label mapping
  • Custom per company, applied automatically
  • Like-for-like across portcos and quarters

Why Haydn

No more spreadsheets. No more chasing. No more surprises at committee.

Today

Chasing portcos and borrowers for data is a quarterly slog. Reminder emails, half-filled Notion forms, copy-paste into your monitoring tool, off-the-shelf AI that chokes on board packs.

With Haydn

Haydn parses every board pack or compliance pack on arrival — numbers and narrative into a structured format — and also supports custom data templates. Your team gets hours back per company, per quarter.

Today

Qualitative and quantitative data live in different places. Board packs in Drive, transcripts in email, KPIs in a spreadsheet — nothing talks to each other.

With Haydn

One source of truth across Drive, Gmail, Outlook, and your CRM. Financials and founder commentary in the same answer.

Today

Partners walk into committee hoping they remember what management said last time.

With Haydn

Ask Haydn. Every commitment, every KPI, every side-comment from every board pack — cited and ready.

See what your portfolio actually looks like.
