PLG with sales-assist triggers
Combine a frictionless self-serve free tier with automated, milestone-based personal outreach to top active users at exactly the right moment to convert.
Why this can grow a startup
Pure product-led growth leaves money on the table for products above $50/month ACV. By tracking usage milestones (first project created, team member invited, free tier limit hit) and triggering a personal email from a real human at those moments, you reach users when they are most engaged and most likely to upgrade. The hybrid model feels helpful rather than pushy because the outreach is timed to genuine product engagement, not arbitrary cadences.
Company example

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.
