Key takeaways

  • Stalled revenue is usually a mis-matched motion, not a product problem — fix the motion first.
  • Choose by economics: ACV < $1k + <1-week cycle → PLG; ACV > $10k + >1-month cycle → SLG.
  • Watch NRR, not just ARR. NRR < 100% is a leaking bucket no amount of new logos fixes.
  • Don't pour paid acquisition in before PMF — you burn cash 10× faster than you learn.

What this is

"People like it but revenue isn't growing" is rarely one problem. It's usually a mis-matched motion — a PLG product run with an SLG playbook, or vice versa. This playbook diagnoses the motion by ACV and sales cycle, then walks the 5-stage path from $0 to $10M ARR across 8 documented case studies.

The 5-stage path from $0 to $10M ARR

  1. 1

    Pre-PMF · $0–$100k

    Run 10–30 user interviews and confirm the must-have before anything else. Do not buy traffic yet — you'll burn cash faster than you learn.

  2. 2

    Early PMF · $100k–$1M

    Invest in 1–2 channels deeply rather than spraying. Find the one repeatable acquisition motion and double down before adding a second.

  3. 3

    Growth · $1M–$5M

    Add affiliate and integration partners; if PLG, layer in sales-assist for the larger accounts that self-serve can't close alone.

  4. 4

    Scale · $5M–$10M

    Stand up an enterprise team, earn compliance (SOC 2), and accelerate channel partnerships. Split contracts into startup / mid-market / enterprise tiers.

  5. 5

    Ecosystem · $10M+

    Open a platform and distribute through investors and agencies. Growth now compounds through partners, not just direct sales.

PLG vs SLG — pick your motion

Don't copy a logo's playbook — match the motion to your deal economics. Decide by ACV and sales-cycle length:

FAQ

What's the best growth motion for an AI SaaS in 2026 — PLG or SLG?

It depends on ACV and sales cycle. Under $5k ACV with a <30-day cycle → start PLG. Above $20k ACV or a >60-day cycle → you need SLG earlier than you think. The playbook has a decision tree with specific thresholds.

When should I hire my first SDR?

Not before you've closed 20 deals yourself as a founder. If you haven't personally sold it, an SDR can't sell it either. The playbook covers the exact signals to look for first.

How do I build an affiliate channel without it becoming a spam network?

Partner quality > partner quantity. The playbook covers how HeyGen and Deel vetted affiliate partners, set commission structures, and designed co-marketing that drives real revenue.

What's the single most-missed B2B metric?

NRR (net revenue retention). Teams obsess over new ARR while NRR quietly sits below 100% — a leaking bucket. The playbook treats NRR as the primary health metric above raw ARR.
