Welcome! I’m David Parrottino, an operator and growth marketer who’s managed over $100M in ad spend and generated $500M+ in revenue for some of the fastest-growing DTC brands online.

I specialize in scaling 7–8 figure e-commerce brands using Meta and Google Ads, with a focus on cost-controlled buying, creative iteration, and contribution-margin-driven decision making.

Over the last decade, I’ve:

Built and scaled my own brand (Kingsfield Fitness) from the ground up to 7 figures in two years

Consulted for leading brands in the ecommerce space. 

Co-founded Ecom Finance & Marketing, a boutique agency where we combine Fractional CMO + Fractional CFO services to help founders align paid media, inventory planning, and cash flow forecasting for sustainable scale

This channel documents everything I’ve learned from spending tens of millions on ads, and what I’m learning right now.
