For growth investors

What growth-equity teams use Haydn for.

Monthly KPI work — from metric normalization to cohort watching to pipeline tracking — without the spreadsheet slog.

SaaS metrics, normalized

ARR, NRR, GRR, LTV/CAC, magic number, Rule of 40 — extracted from every portco's MRR waterfall or finance deck, on a consistent definition across the fund.

Cohort retention & expansion

Retention curves, NRR by cohort, expansion attribution — pulled from every monthly KPI pack, so you spot net-dollar degradation with the source quote cited, before the next board meeting.

Plan variance & burn

Revenue, burn and hiring reconciled to the operating model you underwrote — with variance flagged the moment a portco slips from plan. Burn multiple and months of runway, tied to the latest KPI pack.

Pipeline & bookings visibility

Quota attainment, pipeline coverage, ACV trends — pulled from every monthly sales update or board pack, so you catch a soft quarter before the CFO email lands.

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

Monthly KPI packs, MRR waterfalls, board decks, founder updates. Haydn parses every format — messy Excel and all — and extracts every metric, not just the headlines on the cover page.

  • PDFs, decks, spreadsheets
  • Messy formats handled
  • Audit trail per number
02

Standardize across the portfolio

Every portco defines ARR differently. Compose ARR, NRR and GRR from each company's own line items on a single fund-level definition — applied automatically, every month.

  • Formulas per company
  • Applied automatically
  • Like-for-like comparisons
03

Analyze with an AI that remembers

Ask anything across the portfolio in plain English. Cohort drift, plan variance, hiring commitments — answers come back in seconds, with every number cited to the exact line in the KPI pack.

  • Cited to source
  • Persistent memory
  • Contradictions flagged

Analyse

Haydn parses every KPI pack, normalizes ARR, NRR and GRR on a consistent fund-wide definition, and builds a live cohort and pipeline view for each company.

03

Act

Ask questions, review plan variance, track hiring and revenue commitments, and walk into the monthly check-in already knowing the answers.

An AI that reads every KPI pack, flags every drift, tracks every commitment.

Haydn sits on top of your portfolio's entire document history. Ask it anything — “Which companies have missed plan on ARR two months running?”, “What's driving the net retention dip at Apex?”, “Show me every hiring commitment Omega management has made this year.” — and get cited answers in seconds, with every claim traced back to the original KPI pack, board pack, or founder email.

  • Persistent memory
    Every monthly KPI pack, founder update and board deck you've ever received, instantly queryable.
  • Contradiction flags
    When a founder's ARR definition shifts between Q2 and Q3, Haydn surfaces the change — with both sources cited.
  • Commitment tracking
    Every hiring plan, revenue commitment and GTM promise tracked month-over-month.

Why Haydn

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

Today

Three portcos, three definitions of ARR — one uses committed MRR × 12, one excludes one-time, one blends services.

With Haydn

Haydn normalizes ARR, NRR and GRR on a single fund-level definition, with the board-pack quote cited next to each number.

Today

Monthly KPI packs arrive as a messy Excel — merged cells, hard-coded values, pivot-table exports — nothing a script can touch.

With Haydn

Haydn parses the Excel you already receive — no template, no portco onboarding, no new workflow for the founder.

Today

You walk into the monthly check-in hoping you remember what the founder promised last month.

With Haydn

Ask Haydn. Every commitment, every KPI, every cohort shift — from every pack — cited and ready.
