Yaron Marcus


With over a decade of online marketing experience under his belt, Yaron has developed an expertise in many facets of the business. Having run large, successful campaigns across numerous industries and verticals, he possesses an abundance of  practical knowledge and a unique perspective on digital marketing; all of which he applies in working with clients to ensure their success. Prior to Sellside Media, Yaron served as the Director of Marketing at MediaBoost, where he helped grow the company from obscurity, to one of Israel’s leading performance marketing companies. The company’s Israel division was ultimately acquired by Los Angeles based Centerfield Media, which he joined as Vice President. When not pacing the halls of his office while speaking on the phone, or drawing graphs on a whiteboard, Yaron enjoys crashing drones and hiking with his wife and three boys.

Tara Horn


As our Director of Client Services, Tara is the driving force behind our mission to boost growth for our clients through results-driven strategies. She applies her vast understanding of online marketing strategy, design, product development, user behavior, conversion optimization and data analysis to each client. She’s made an art of breaking down complex marketing terms to easily understandable information for her clients. Tara’s background in online marketing and project management serve her well in her role as the person responsible for making the magic happen for the clients she serves. When not creating ads or meeting with clients, Tara spends her time playing baseball with her kids and eating peanut butter with a spoon.

Eric Landa


As our Director of Disruption, Eric knows how to grab people’s attention. When a client needs to spice things up with their ads or landing pages, Eric gets the job done. He’s the creative force behind the skyrocketing click-through and conversion rates on many of our campaigns. He’s also a numbers guy, pouring over campaign stats late into the night (when his wife lets). His years of media buying and affiliate management experience have made him a master negotiator when it comes to structuring great media deals for his clients. When he’s not walking across town to save 5% on deli meat, Eric can be found on the basketball court or with his family at the bottom of a 3 child pile-on.

Miriam Marcus

miriam marcus

Miriam handles the company’s accounting and financial matters. Her experience includes management roles in finance and operations across a variety of industries. It’s been suggested that her speed is the result of a caffeine addiction, though credible sources have verified that it is in fact natural. Miriam dashes around the office, keeping our finances in order and helping our clients keep track of their ad budgets. When she’s not using accounting jargon or schlepping around binders of receipts, Miriam enjoys working out (not that anyone enjoys it, but she tries) and taking her boys on local adventures.
