Founder Feature: Marc Brown of ONOIN

In this episode of the Startup CPG Podcast, host Caitlin Bricker sits down with Marc Brown, founder of ONOIN — a line of shelf-stable, pre-chopped and flavored onions in 100% olive oil designed to save you time and tears in the kitchen. ONOIN comes in four flavors — original, garlic and herb, jalapeño lime, and ginger and lemongrass — and is designed to go on or in anything, from eggs to meatballs to savory oatmeal bowls.

Marc is a food scientist with a master's degree from Drexel University and a seriously stacked background: R&D and industrialization at Danone, Head of R&D as employee #8 at Clio Snacks, and R&D and contract manufacturing work at Hain Celestial. He came to founding ONOIN with a rare 360-degree view of the food industry — from bench science to co-manufacturer negotiations to retailer conversations — and shares hard-won lessons throughout this conversation.

Together, Caitlin and Marc dig into why chopped onions in a jar hadn't been done before (and why it should have been), the origin story of the ONOIN name (credit goes to his brother-in-law at a backyard grill), and what makes a co-manufacturer relationship truly work. Marc breaks down the three-part pricing transparency framework every brand should demand from their co-man — raw, pack, and toll — and explains why trust and belief in your vision are just as important as the contract.

They also get into the realities of early-stage distribution, how to build a velocity story with the right retail partners, and why knowing your product well enough to tell a buyer exactly why they need it on the shelf is non-negotiable.

Listen in as they cover:

• How a graduate school innovation exercise sparked the idea for ONOIN
• Why shelf-stable pre-chopped onions solve a problem that fresh never fully could
• The naming journey from "Yun" to ONOIN — and why the name works on shelf
• The three things every brand must demand from their co-manufacturer: raw, pack, and toll
• Red flags when vetting a co-man and why trust is the ultimate filter
• How Marc's background at Danone, Clio Snacks, and Hain Celestial shaped his approach to founding
• Building a velocity story with retailers who actually believe in your product
• Why knowing your product's ideal placement in store can change your whole sales conversation
• Reducing food waste — one of ONOIN's often-overlooked benefits

Whether you're a founder navigating co-manufacturer relationships, a food scientist thinking about making the jump to your own brand, or a buyer looking for the next smart pantry staple, this episode is for you.
