Darren McMurtrie

Co-Founder

Darren McMurtrie is co-founder and COO of Ensurva. He writes about the operational mess of scaling a company, specifically what breaks in operations and IT inside small to mid-sized businesses, and why vendor sprawl is usually a symptom of something bigger.

Before Ensurva, Darren co-founded Assembly Payments, now MX51 and Zai. The company scaled past $28B in transaction volume and raised over $100M in venture capital. As COO of Hapana, Darren grew headcount from 56 to 120+ staff across five countries and co-led a $17M funding round.

Both experiences showed the same pattern: vendor relationships multiplying faster than anyone could track them, with the operational cost showing up months or years later. Darren has sat in the seat where a team buys a tool without telling IT, where two departments pay separate vendors for the same job, and where a surprise renewal costs less in the invoice than in the scramble that follows it.

On the Ensurva blog, Darren writes for operations leaders mapping vendor ecosystems they didn't design, and for IT leaders who want to stop discovering vendor relationships by accident.

Writes about

  • Vendor sprawl and where it actually comes from
  • Operations at scale
  • Shadow IT and offboarding risk
  • Building systems that don't depend on one person's memory
