The Builder Note is your sales pitch. Here is how to write one that converts.

Understand the Purpose of a Builder Note

A Builder Note is the first document a buyer reads after signing the NDA on platforms like hades.ae, Empire Flippers, or Acquire.com. It replaces the executive summary and must communicate the business model, traction, and opportunity in under 800 words. Buyers reviewing 15–20 listings per week spend 90–120 seconds on this note before deciding to request financials.

Structure That Matches 2026 Buyer Expectations

Start with a one-sentence hook that states exact 2025 revenue and growth rate. Follow with five short sections: product overview, go-to-market, unit economics, risks and mitigations, and the ask. Use bold subheads and bullet points so skimmers can extract MRR, churn, and gross margin within 30 seconds.

Opening Hook

“$187k ARR SaaS with 19% MoM net revenue retention and 4.1% monthly churn, sold via product-led growth and 12 enterprise pilots in progress.” This single line sets valuation expectations at 3.8–4.2× ARR before any deeper reading begins.

Product and Traction

  • Core workflow: automated invoice reconciliation for mid-market accounting teams, currently processing $42M monthly transaction volume.
  • Key metrics: 142 paying customers, $1,317 blended ARPU, $183k TCV pipeline, and 31% of revenue from annual contracts.
  • Tech stack: Next.js frontend, Supabase/Postgres backend, deployed on Vercel with Stripe billing and Segment analytics.

Unit Economics and Valuation Anchors

Buyers apply 2–5× ARR multiples depending on churn and growth. A 4% monthly churn with 15%+ growth typically lands at 3.6×. Include the exact calculation: LTV $7,902 at 22-month average lifetime, CAC $812 via organic channels, yielding a 9.7× LTV:CAC ratio. State SDE of $94k after normalizing founder salary to market rate, giving acquirers a clear path to 38% EBITDA margin post-integration.

Risks, Mitigations, and Transition Plan

Address single-founder risk, key-customer concentration (top client = 11% revenue), and dependency on one Stripe integration. Offer a 60-day transition with daily Loom updates, shared Notion workspace, and 10 hours per week of founder consulting included in escrow. Most deals on hades.ae and MicroAcquire close with 10–15% held in escrow for 12 months.

Final Polish Before Listing

Export as PDF, embed 3–5 charts (MRR trend, cohort retention, CAC by channel), and run Grammarly plus a peer review from another founder who has exited. Listings with a polished Builder Note receive 2.4× more LOI requests within the first 14 days than those with only raw financials.

How long should my Builder Note be?

Keep it between 600–800 words; buyers abandon anything longer than two pages on mobile.

Should I include exact revenue numbers?

Yes. Obfuscated ranges (“six figures”) reduce response rates by 60% according to FE International data from 2025.

Do I need professional photos or just screenshots?

Three high-resolution product screenshots and one founder headshot increase conversion by 35% on Acquire.com listings.
