Justin Fineberg built a 500,000+ follower audience on TikTok and Instagram before launching Cassidy, an AI automation platform for non-technical users. By consistently creating content about AI and technology, he turned inbound interest into his initial customer base and market validation. In this episode of BUILDERS, Justin breaks down how he leveraged short-form video to identify product opportunities, the mechanics of maintaining authentic audience relationships while monetizing, and how to transition from social-led distribution to scalable B2B SaaS go-to-market.

Topics Discussed:

Leveraging ChatGPT's launch as an inflection point to ride mainstream AI interest
Converting consultant requests into product insights and early customer signals
The platform mechanics of TikTok vs Instagram for B2B content
Transitioning from 100% social-sourced revenue to multi-channel B2B sales
Building repeatable content systems that survive founder time constraints
Testing product messaging and features through content before formal launch

GTM Lessons For B2B Founders:

Timing content focus with market inflection points compounds growth
Inbound consulting requests are product requirement documents in disguise
Content systems must be friction-free or they'll die under operational load
Good content transcends platform-specific algorithm hacking
Social distribution creates unfair launch advantages, not permanent moats
