PLG + sales-assist hybrid activation model
Combine zero-friction self-serve signup with automated, milestone-triggered personal outreach to convert the most active free users at 30-50% rates.
Why this can grow a startup
Pure product-led growth leaves money on the table for products with higher ACV, while pure sales-led is too expensive at early stage. The hybrid model uses product usage data to time human outreach precisely — when a user hits a key milestone (first project created, team member invited, usage threshold), a short personal email or 15-minute call offer converts at 30-50%. This costs nothing in sales headcount because it targets only the top 10% most active free users, not everyone.
Company example
Common among B2B SaaS with ACV above $50/month (Postiv, Loom, Notion early growth)

When to use it
Use this when Email, Referrals is relevant to 0-100, 100-1K and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
Founder checklist
- Read postiv.ai and identify what is directly supported.
- Choose one channel context: Email, Referrals.
- Define the test around 50% rates.
- Set an owner, evidence window, and stop condition before launch.
