Nikki Post joins Cowbell to lead Professional Lines

by | Nov 9, 2026 | Corporate

Every business that gives advice, writes or signs off on someone else’s work carries a quiet risk: one day, a client may say it went wrong and send the bill. Professional liability is the cover that answers that call. Today, Cowbell welcomes Nikki Post as Product Leader, Professional Lines, to make sure our answer is a good one.

What Nikki will lead

Nikki will head up Cowbell’s professional liability portfolio – covering product strategy, coverage design, and pricing, working with our underwriting, claims, and distribution teams. Her brief is simple to say and harder to do: build professional lines products that brokers can place quickly, and policyholders can actually understand.

Why now

Cyber and professional liability are increasingly hard to separate. A software bug, a missed patch, or a misconfigured cloud server can trigger both a data breach and a claim that a service failed. Nikki’s role is to take that thinking further across professional lines, using the same data and AI-driven underwriting that powers our cyber products.

Nikki’s background

Nikki brings more than 13 years of underwriting and product experience across professional liability and cyber. She joins from Twin Maples Specialty, where, as Head of Professional Liability & Cyber, she led product, underwriting, and distribution across miscellaneous professional liability (MPL), architects and engineers (A&E), contractors professional, cyber, and Tech E&O. Her work there included modernizing policy language and building cover for new professional classes.

Before that, she spent five years at At-Bay as Vice President, Southeast. She built an eight-person underwriting team from the ground up and turned a small regional cyber and Tech E&O portfolio into one of the company’s largest.

Earlier, at Hiscox, she managed a professional liability portfolio and was the go-to expert on allied healthcare and A&E risks. She started her career on Zurich North America’s underwriting training program, writing international construction programs. Nikki holds an MSc in International Relations from the London School of Economics.

“Professional liability must evolve alongside the businesses it protects. As technology and AI reshape how companies operate, new exposures are emerging that require a more modern approach to coverage,” said Trent Cooksley, co-founder and COO of Cowbell. “Nikki brings extensive experience building cyber and Tech E&O portfolios, modernizing professional liability coverage, and understanding what brokers need. We’re excited to have her on board as we expand our professional lines capabilities.”
