Bio

Over the past 10+ years, I’ve grown a software studio from the ground up to 60+ people, delivering more than 60 digital products. I’ve faced the hard decisions that come with building and leading a company — hiring, firing, raising, surviving crises, and scaling. Along the way, I’ve invested in 11 startups and served as a trusted thinking partner to dozens of founders and execs. My strength lies in exposing what’s not being said — the flawed assumptions, contradictions, and blind spots that often derail progress. My background combines real-world startup scars with a deep curiosity about decision-making: systems thinking, cognitive biases, heuristics, and probability. I ask sharp questions, connect dots quickly, and help you untangle the complexity you’re too close to see. What you’ll get from a call: • Clearer thinking under uncertainty • Faster insight into what’s missing or misaligned • A candid, thoughtful sparring partner who’s been in the trenches

Expertise


  • Mindset coaching

    Decision-making starts with mindset. I’ll help you step back, challenge limiting beliefs, and spot unhelpful patterns. Whether it’s fear, ego, or doubt, we’ll clear mental roadblocks so you can lead with focus and confidence.

  • Product market fit

    I’ve built 60+ products and advised countless founders. I’ll help you ask the right questions, spot weak assumptions, and challenge your positioning. Together, we’ll sharpen your value proposition and test if you’re truly solving the right problem.

  • Technology and tools

    As a technical founder, I’ve led teams through dozens of product builds. I’ll help you assess your tech stack, spot inefficiencies, and choose the right tools — not just what’s trendy, but what actually supports your business goals and reduces complexity.

  • Venting frustration

    I’ve been through the founder rollercoaster myself. I know what it’s like to be stuck, overwhelmed, or doubting your own thinking. I create a safe space to vent, unpack what’s really going on, and turn frustration into clarity and action.
