Amber Coster - Fractional COO

About Amber Coster - Fractional COO

I love the work you hate. You didn't start the company to spend your week in the operational weeds - untangling who owns what, chasing decisions that should already be made, holding the whole rhythm together on willpower. That's my work, and I love it. I'm a fractional COO for founder-led B2B tech. Not the consultant who diagnoses and disappears - I embed as your operational number two and stay for as long as you need one. I work two ways: Anchor — one company, two or three days a week. In you business, building the operating rhythm, getting the leadership team excited and owning their patch, handing you back your time. Advisory — a handful of founders I partner with more lightly. A sharp 90 minutes every fortnight to pressure-test the hard calls and keep you out of the weeds. As COO at Unmind I cut burn by 58% whilst improving engagement, culture and accountability. Before that I was the regional number two at AppDynamics, from a $100m valuation through IPO-readiness to Cisco's $3.7bn acquisition, and I built ClickUp's first senior EMEA leadership team through 233% growth. I keep the roster small, working with ambitious businesses, founders and CEOs who care about their people as well as their business. → If any of that lands, let's talk: ambercoster.co.uk
