SaaS Product Validation: 3 Products, 1 Winner

Bart Lorang and his co-founders had a problem most founders would love to have - too many ideas. They were finding product-market fit signals in one product while chasing two others. The SaaS product validation lesson was hiding in plain sight. Rainmaker, a simple Google contacts tool, kept getting customers while the founders ignored it. In this episode, Bart shares how validating SaaS idea after SaaS idea taught him that the best product is the one customers already chose.

The founders built three products simultaneously, spreading resources too thin. SaaS product validation finally happened when they accepted that only Rainmaker had real customer demand. They killed two products, doubled down on the one with SaaS idea validation from paying users, and turned it into FullContact - which raised $25M+ and grew to 300+ employees.

Bart Lorang is the co-founder and CEO of FullContact, a SaaS product that transforms partial contact information into complete profiles and more useful customer data.

🔑 Key Lessons

• 🎯 SaaS product validation means following customer signals: Bart built three products but only one had paying customers. The market was already telling him which product had finding product-market fit - he just needed to listen.
• 📉 Chasing new ideas kills momentum on what works: FullContact's founders spent months building new products while ignoring Rainmaker, the one tool customers wanted. Shiny object syndrome nearly cost them everything.
• 🚀 Marketplaces give early-stage SaaS free distribution: Launching Rainmaker in Google's marketplace gave FullContact instant access to people searching for contact tools, bypassing the cold-start problem entirely.
• 🧠 SaaS product validation often means killing your other ideas: The team shut down two products they were excited about to commit fully to the one with real traction. Focus requires sacrifice.
• 💰 Scratch-your-own-itch ideas can scale to $25M+ in funding: Bart's original insight came from watching his wife organize contacts. That personal frustration became a $25M-funded identity resolution platform.
• 🔄 Pivot from consumer to enterprise when the data shows demand: FullContact started as a simple Google contacts tool and evolved into an enterprise identity resolution platform as they discovered bigger market opportunities.
