Interview: Sam Parr on how to grow on Twitter, selling a company, and the best social media platforms to choose

Sam Parr built The Hustle from a small email experiment into a 2-million-subscriber newsletter that HubSpot bought. The magic? Relentless audience focus and smart content distribution.

Marketing Analysis

Sam didn’t try to be everywhere. He used Twitter to grow his personal brand, then funneled that awareness into the newsletter. Once readers were hooked, The Hustle used a clean, consistent email format that felt more like a friend’s update than a corporate blast.

Why It Works

• Focused on one channel before expanding
• Built trust with authentic, opinionated writing
• Created repeat engagement with consistent, predictable formats
• Leveraged the founder’s personal brand for growth

Examples

• Morning Brew grew from 50 to 4M+ subscribers using the same formula
• HubSpot bought The Hustle for its hyper-engaged audience
• James Clear turned a newsletter into a 10M-copy bestseller
• Ali Abdaal used consistent YouTube content to grow a 4M+ following
