Karl Nislow

Startup Finance & Ops Expert - CPG & Tech (Top 3%)

Hi, I'm Karl! I currently serve as a fractional Head of Finance and Chief of Staff (CoS) to a handful of startups in the Technology and Consumer Packaged Goods (CPG) industries.

My general approach is focused on scalability, high-touch analysis, and automation wherever possible. I'm known for breaking the traditional corporate mold by simultaneously improving your brand's health while also being someone you genuinely enjoy working with.

** I'm especially passionate about supporting purpose-driven brands. Many of the brands I work with are focused on health, wellness, and sustainability. In the top 3% of consultants via Toptal. **
