Outbound Engine: Bill Stathopoulos on Scaling B2B Startups, Cold Email Mastery & Building with Purpose

Start. Scale. Exit. by Sintesys

Episode Summary:

In this episode of Start. Scale. Exit., Ivan Galvez sits down with Bill Stathopoulos, CEO of SalesCaptain, Clay London, Club Lead, Top Lemlist Partner, and a go-to expert for building B2B outbound systems that work. Bill shares how he took a startup from just $200/month in revenue to over $1M using cold email, laser-focused ICPs, and scalable outbound frameworks.

Together, they dig into the architecture of great outbound: what founders get wrong, how to build campaigns that convert, and why most early-stage companies don’t fail from a lack of effort, but from poor targeting and messaging. Bill also opens up about how childhood Lego-building turned into a lifelong obsession with scalable systems, team building, and long-term thinking.

If you’re a founder or GTM leader looking to replace founder-led selling, scale your sales motion, or unlock outbound at a whole new level—this conversation is packed with tactical insight and grounded inspiration.

🔑 Key Takeaways:

• How Bill scaled a startup from $200 to $1M+ in revenue using outbound only
• Why great outbound = targeting × messaging × deliverability
• The mistake most founders make when they send cold emails
• How AI and automation tools like Clay are reshaping outbound
• The truth about “done-for-you” outbound—and why frameworks matter more than tools
• What it takes to scale sales without scaling burnout
• The critical role of early systems in reducing founder dependency
• Why outbound start before your product is even ready
• The power of personal purpose in long-term startup building
• How to build, test, and scale outbound like a product

💡 Golden Nugget:

“Outbound isn’t about being louder—it’s about being more precise. You don’t need more leads. You need the right ones, with the right message, at the right time.”
