About

Your team doubled. Execution slowed down. Decisions still go through you. You hired smart people. You might have even brought in an HR specialist. But the way your team works together hasn't kept up with how fast the business has grown. That's not a people problem. That's a culture problem. And it's yours to solve. I'm a Fractional Head of People who works with founders who put their People first and want the culture to match. I design the operating system that shapes how your team actually works together: purpose, vision, values, decision making frameworks and the people processes that turn all of it into behaviours. The goal is a thriving team and a business that runs without you in every detail within 12 months. 19 years working with high growth startups, 20 years leadership experience. 20+ countries, multiple industries. Seed to Series C. I've built every people system from scratch, multiple times and I know what breaks when you try to scale without the right culture foundations. Here's what changes when founders stop being the bottleneck and build a culture that works: - Nium: Scaled from 3 to 9, built a culture of responsibility and ownership. No full time People support needed. - Chassis Autonomy: Cut ramp up from months to weeks. Turnover at 6.6% vs. 30.8% industry average. - Formalize: Established People Operations from 50 to 100, ahead of hiring a full time People team. - Nivoda: Doubled to 500, saved £250k/year, automated admin, cut onboarding by 22 hours/week. You can't scale without chaos, but you can definitely scale with less chaos. I'm not for everyone. If you think people are the problem rather than the product of the system you've built, I'm not interested. If you want someone to "clean up People problems" while you keep leading the same way, I'm not the right partner. If you're willing to look at how your leadership shapes your culture and you want a team where people thrive because the foundations are right, then we should talk.

Chief People Officer

Apr 2025Present · 1 yr 1 mo · United Kingdom · Remote

  • Hiring is eating your time and as a People Leader, you have precious little of it.
  • I know, I was there.
  • Sourcing, CV screening, intro calls, all the admin that comes with it.
  • And yet, the candidates we interviewed were just OK.
  • I changed channels, outreach approach, search terms… In my search to improve the quality of candidates, I looked back over the hiring managers feedback and noticed a thread: candidates didn’t demonstrate they had the right skills for the roles they had applied for.
  • 💡What if I found a way to test the skills first?
  • I looked around, took a few webinars and turned our recruitment process on its head: testing the skills first.
  • 🎯The results?
  • Improved time to hire by 2 weeks (1.5 months to 1)
  • Saved over 10h a week
  • Improved diversity across the team by over 20%
  • Prioritising skills gave us access to better candidates, saved time and was the starting point for better business outcomes.
  • And now? @MythicHire makes sure that you can too.
