Michael Penner
Every verdict on The Shelf Signal is his call: Real, Niche or Fad, dated, with the reasoning kept on the record.
Mike Penner is an operator. Through Exklusive Solutions he works as a contracted COO and CTO for premium and experimental grocery, hospitality and retail businesses, mostly in the start-up and growth phase, bridging technology, operations and finance.
That is the lens on every trend here. He has merchandised, priced and sold the categories the site judges, so a verdict asks the questions a store asks: would we carry it if it weren’t trending, does it earn its facing at the department’s margin, and will shoppers buy it again.
He is the author of The Truth Behind Premium Grocery (coming 2027), written from the store’s side of the table: how a premium grocer decides which brands come in, how they are priced, kept and dropped. The site’s playbooks and shelf price calculator are adapted from it.
Some of the businesses he works with are premium grocers. They appear on the site only through public information; no client data or products are used, and verdicts are about trends, not retailers.
