Denise Mathews - Executive Assistant | Early Stage Startup Ops

About Me

I'm a multi-talented, surprisingly technical former "HR for startups" professional who excels at Marketing and fixing inefficient processes.

My expertise spans end-to-end executive operations (calendar management, investor relations coordination), building internal tools and websites, quickly learning code to automate workflows, and creative execution (marketing content writing and video editing). I excel in fast-paced, ambiguous environments where I can identify inefficiencies, build solutions, and work closely with leaders to build the foundations of highly successful companies.

Ideal roles:

First Non-Eng hire (Ops, Marketing, Sales Ops, Exec Support)
Fractional HR & Ops support for portfolio companies
