Growth Hacking Strategy for SaaS Startups (How to Acquire 100K Users)

TL;DR

Getting to 100,000 users isn't about luck or a single viral moment --- it's about engineering growth systematically. TK Kader unpacks the growth hacking strategies that successful SaaS startups use to scale from zero to six-figure user bases without burning through their runway. He covers the full growth stack: viral acquisition loops that turn users into your best marketing channel, onboarding optimization that reduces time-to-value and cuts churn at the source, and low-cost acquisition channels like content marketing, communities, and strategic integrations. TK also explains how to run structured growth experiments using the ICE (Impact, Confidence, Ease) framework so you're not just trying random tactics. The video includes real examples from SaaS companies that scaled efficiently, along with the mistakes that killed growth for others. Whether you're pre-product-market fit or scaling past $1M ARR, the principles here apply anywhere you need to accelerate user acquisition without a big marketing budget.
