In 15th-century Venice, a 125-pound sack of black pepper purchased in Calcutta for $3,000 resold for $120,000 — a 2,700% markup. Nutmeg cleared 600x its cost at origin. Modern cocaine, by comparison, moves at roughly 13x.
Venice didn't grow a single peppercorn. It controlled the space between the people who produced spice and the people who wanted it. That positioning alone built one of the wealthiest empires in European history.
Columbus, da Gama, the Dutch East India Company (the world's first publicly traded company) all trace back to the same bet: whoever can deliver the product directly to the buyer, without the gatekeeper, captures the margin. Not a new product. A shorter route to someone already paying too much. That's the oldest startup idea in the world, and it still works.
Every industry has its Venice — a gatekeeper charging 27x for proximity, not production.
Right now, there's one inside the American café industry. Starbucks ships cold foam, protein add-ons, and layered pours across 16,000 locations while 94,000 independent cafés watch from the sideline. Not because they lack talent — because nobody's packaging the innovation for them. Add-ins alone clear over $1 billion a year for Starbucks, and the supply chain to independents doesn't exist.
Today's business idea is the shorter route: a ready-to-use hojicha cold foam base that turns 2026's breakout flavor trend into a ten-second add-on any barista can pour. One café moving 40 foamed drinks a day at a $1.25 upcharge nets roughly $1,500/month in new margin, on an ingredient that costs the operator about $0.20 a serving. Supplier-side gross margins: 55–70%.

Cold foam is a billion-dollar menu mechanic at Starbucks, but independent cafés lack the R&D to execute it. A ready-to-use hojicha foam base is a high-margin foodservice business idea built on converging trends.
