About Jack Portman
I work with ecommerce brands and Amazon sellers who are investing in advertising but aren’t always sure how efficiently their budget is being used.Many teams I speak with are dealing with rising CPCs, inconsistent returns, or the challenge of scaling new products without increasing wasted spend.At Quartile, we help brands improve ad performance through a mix of AI-driven automation and hands-on Amazon expertise. On average, clients see over a 41% increase in ROAS.If you ever want to compare notes on your ad setup or see where there may be opportunities, I’m always happy to connect.
