PLG Works For Infrastructure
Product-led growth (self-serve signup, usage-based expansion) will work for developer infrastructure products like SmartBoxes and Nomos Cloud.
The Assumption
We’re betting that developers will:
- Sign up and try SmartBoxes/Nomos without talking to sales
- Expand usage organically based on value received
- Convert to paid through product experience, not sales calls
- Refer colleagues based on product quality
The alternative hypothesis: developer infrastructure requires enterprise sales from day one. If true, our low-cost acquisition strategy fails and we need a different GTM (sales team, higher prices, longer cycles).
Evidence
PLG success in developer tools:
- Vercel, Netlify, Supabase all grew through self-serve signups
- Stripe famously built on developer word-of-mouth
- GitHub, GitLab grew bottom-up before enterprise sales
- Tailwind CSS, Prisma built massive communities before monetising
PLG-friendly signals in our market:
- Developers try tools before committing
- AI developers especially experimental—always trying new things
- Low switching costs mean easy adoption
- Credit-based pricing (PAYG) aligns with PLG model
Counter-signals:
- Infrastructure decisions often require security review
- Enterprises may block unapproved tools
- Some developers need permission to expense tools
- High-value deals may still require sales touch
Counter-Evidence
What would prove this wrong:
- All deals require sales touch to close
- Self-serve churn exceeds 20% monthly
- CAC payback exceeds 18 months
- Free tier users never convert
Warning signs:
- Signups don’t convert to active usage
- Users sign up, try once, disappear
- Enterprise prospects say “we need to talk to sales”
- Conversion rate under 2%
Impact If Wrong
Products affected: SmartBoxes and Nomos Cloud primarily
GTM impact:
- Would need to hire sales earlier than planned
- Would need higher prices to cover sales CAC
- Would shift focus to enterprise from SMB/indie developers
- Would slow growth rate significantly
Unit economics impact:
- PLG CAC: ~$50 (content + free tier costs)
- Sales-led CAC: ~$500+ (sales time + demos + trials)
- Need to 10x prices if sales-led, which shrinks addressable market
Runway impact:
- Sales-led requires upfront investment before revenue
- Longer payback period strains cash flow
Testing Plan
Key metrics to track:
- Self-serve signup rate: Target >100/month by month 6
- Trial-to-paid conversion: Target >5%
- Expansion revenue: Target >100% net revenue retention
- Time-to-value: Target under 10 minutes to first successful run
Experiments:
- Publish technical content, track signups from content
- Optimise onboarding for time-to-first-success
- Test different credit packages to find conversion sweet spot
- A/B test self-serve vs. “request demo” buttons
Timeline: Validate within first 3 months of public beta
Kill criteria: If fewer than 50 self-serve signups in first 3 months of beta AND conversion under 2%, consider sales-led pivot.
