I recently dug into a conversation with Marco Zappacosta, co-founder and CEO of Thumbtack, who has spent the last 13 years building the company into a billion-dollar business — and it’s his first and only job after graduating college. As someone who lives at the intersection of product management leadership and company-building, I was struck by how deliberately he navigates the deluge of advice that comes with being a first-time founder.
What resonated most was the way he differentiates between moments that demand a return to first principles and those that benefit from a tested playbook. In my own practice, I’ve found that product strategy and organizational design often require first-principles thinking, while operational cadence and execution rituals tend to scale best with proven patterns. The key is recognizing which game you’re playing — invention versus optimization — and applying the right mental models to filter input without losing velocity.
Marco’s approach to parsing counsel as a first-time CEO is refreshingly pragmatic. Rather than treating advice as binary, he triangulates from multiple data points, looks for invariants, and pressure-tests assumptions against the company’s unique context. I use a similar lens: anchor on the problem, map potential solutions to risk/return, and calibrate decisions with base rates where possible. It’s a disciplined way to turn a mountain of opinion into actionable signal — especially when stakes are high.
He also connects this discipline to stakeholder management, particularly in how he runs Thumbtack’s board so quarterly meetings become a critical resource, not just a time suck — and why he shares the board deck with the entire company. I’ve found this level of transparency to be a force multiplier: it aligns teams on priorities, elevates product roadmapping and sprint planning, and empowers leaders to make trade-offs with clarity. When the narrative is shared, accountability scales.
Marco candidly reflects on Thumbtack’s COVID-related layoff last year, and what he specifically did as CEO to ensure the folks who remained still had confidence in the company and his leadership moving forward. In hard moments like these, consistent communication, explicit prioritization, and a clear framework for decision-making matter more than ever. Trust is built by showing your work — why choices were made, what changes now, and how success will be measured.
Finally, he opens up his playbook for choosing what to spend his time on as a busy CEO with only so many hours in the day — and perhaps more importantly, how he stays accountable for these priorities. I’ve learned to pair outcome-oriented OKRs with a ruthless weekly schedule audit: if the calendar doesn’t reflect the strategy, the strategy won’t happen. This discipline creates focus, accelerates learning loops, and keeps leaders from becoming the bottleneck.
For builders at any growth stage, there’s a powerful takeaway here: cultivate a repeatable way to distill advice, clarify when to use first principles versus a playbook, operationalize board relationships as strategic assets, and turn time into your sharpest instrument. The result is a more resilient company — and a leadership practice that compounds.
