Amber Coster

Commercially minded COO with a track record of running B2B Tech businesses internally so founders can return to their zone
of genius. Experienced across hyper-growth, acquisition and integration, and organisational transformation at Series B onwards.

Known for bringing calm to chaos, connecting the dots, and building cultures where high performance and genuine care for people coexist. I’m a champion of redesigning how work gets done, not just doing more of it.

I lead AI transformation — evolving how organisations work so AI multiplies output and revenue, protects margin, and keeps and grows the right talent, where efficiency never comes at the cost of the culture

I partner with founders and executive teams to run the business internally, freeing them to focus on vision and product while I handle the operational engine.

Operational Transformation
Streamlining org structure, tools and processes for sustainable, efficient growth.

Culture & Change
Leading whole-org culture transformation using diagnostic tools like OCAI.

Scaling & M&A Integration
Building operational infrastructure for hyper-growth, regional expansion and post-acquisition integration.

AI-Led Efficiency
Evolving how organisations work so AI multiplies output and revenue without costing culture or talent.

Executive-level operational leadership without the full-time overhead — from fractional COO engagements to hands-on transformation work.

Having taken Unmind from Series B scrappiness to Series C operational maturity, built EMEA from scratch at ClickUp through
233% growth, and scaled AppDynamics’ region from 6 to 360 people through to a $3.7bn Cisco acquisition, I bring a proven
record of running businesses through hypergrowth and transformation. I bring calm to chaos, connecting the dots
and building cultures where high performance and genuine care for people coexist.
