One founder, one CSV, and the first real segments Carriage Coffee ever had
The setup
Carriage Coffee Co. is a four-person roaster that ships beans to people who care a little too much about their pour-over. Marcus founded it, roasts most of the coffee, and, because there’s no budget for a marketer, writes every email himself at 6am before the roaster heats up.
The problem
His whole list got the same email. New customer who bought one bag last week? Same email. The subscriber who’s been on auto-ship for two years? Same email. Marcus knew it was lazy, but the alternative felt like a project he didn’t have time for: hire someone, learn SQL, or pay for a “customer data platform” that cost more than his cold brew line made in a quarter.
“I had a hunch there were maybe three or four kinds of customers in there,” he said. “I just had no way to prove it or act on it without it eating a whole month.”
The turning point
He’d assumed segmentation was a paid, technical thing. It wasn’t. He signed up for Divisio’s free tier, dropped in his customer CSV, and ran pattern detection.
The honest question with any clustering is always how many segments? Marcus had no idea, so he let the elbow chart answer it. The curve bent hard at five and flattened after, so five it was. Divisio found them and laid out the heatmap summary, each segment as a row, colored by how far it sat from the average customer.
The hunch was right, and then some. Five clear groups: brand-new one-bag buyers, steady monthly subscribers, big-basket gifters who showed up at the holidays, lapsed regulars who’d gone quiet, and a small core of high-frequency superfans.
How he did it
- Signed up for the free tier, no credit card.
- Dropped his customer CSV straight in.
- Ran pattern detection and used the elbow chart to land on five segments.
- Read the heatmap summary to see what made each segment different.
- Renamed the segments in plain English and sketched an email for the three that mattered most.
The payoff
Marcus didn’t try to run five campaigns. He ran three. A “start here” sequence for new one-bag buyers, a “you’ve been gone a while, here’s 15% back” note for the lapsed regulars, and an early-access drop for the superfans before anything went public.
The lapsed note alone won back a chunk of customers he’d written off, and the superfan early-access turned into his best-selling limited roast of the year because the right 400 people heard about it first. Total spend on the tooling: zero.
“I thought ‘customer segmentation’ was a thing other companies could afford. Turns out I did it before the roaster finished warming up, on the free plan, and it changed how I email people.”

Feature spotlight: Pattern detection (Free)
The classic that everything else builds on. Pick the number of segments, or let the elbow chart suggest it, and Divisio finds the patterns hiding in your data, then lays them out in a heatmap summary so you can see what makes each group tick. It’s on the free tier because every marketer deserves a first real look at their customers, no budget required.
