How User Psychology Grew a Dating App to 17 Million Users With Almost No Marketing Budget ft. Colin Hodge

Colin shares the raw, behind-the-scenes reality of moving from a cushy engineering role at Microsoft to the high-stakes environment of a Silicon Valley accelerator. He discusses the pivotal "moment of liberation" when he admitted his initial startup idea was failing, a realization that cleared the path for him to co-found a viral sensation overnight.

The conversation dives deep into the intersection of technology and user psychology. Colin explains how understanding human behavior allowed him to scale a product to 17 million users and later lead growth for a live-streaming giant in Asia with over 100 million users. He breaks down why technical leaders must look beyond the code to understand the "psychological levers" of their customers, whether they are building B2C dating apps or complex B2B platforms.

Mark and Colin also explore the evolving role of the CTO in the age of AI. Colin argues that as AI makes the digital landscape noisier and more automated, the competitive advantage shifts to leaders who can empathize and connect with people. This episode is a masterclass in growth strategy, the psychology of negotiation, and why "judgment" is the most valuable asset a tech leader can bring to the boardroom.

Key Takeaways

  1. The Power of Admitting Failure: Admitting a product is failing is often the necessary liberation to clear the path for a high-growth idea.
  2. Psychology Over Code: Growth is driven by understanding the psychological levers of acquisition and retention rather than just adding features.
  3. The AI Human Advantage: As AI automates digital noise, the primary competitive edge for leaders shifts toward human empathy and judgment.
  4. Strategic Friction: Real growth involves framing user choices and occasionally adding "good friction" to nudge people toward higher-value actions.
  5. Team Empathy as a Lever: Success requires framing technical decisions with the team's emotions in mind to ensure smooth execution.
  6. Pricing Strategy as Growth: Behavioral triggers, like the "second cheapest bottle" effect, can be applied to tech products to increase revenue.

Mark Wormgoor

How do you decide which tech to bet on when AI is moving so fast?
And everyone expects you to have all the answers?

I work alongside leaders when technology decisions keep them up at night. Over the past 30 years, I’ve been in those moments myself - leading large global IT organizations, consulting for industry leaders, and advising executives and boards.

What I’ve learned is that the hardest part isn’t the technology itself. It’s setting the right direction, building teams that can execute, combined with rigorous execution.

Today, I lead Tairi. We work as a strategy, coaching and execution partner for leaders where technology is a real driver of business value, not just a supporting function.

As technology and AI continue to reshape businesses, my focus is simple: helping leaders make the right tech decisions - and execute on them.
