SEGMENT, ALWAYS SEGMENT Most confounding business problems have the same root cause: you haven't segmented your customers. You look at the top-line number. It's flat, or weird, or inconsistent with what your gut tells you. You poke at it and you can't figure out why. The answer is almost always that you're staring at an average that's hiding two or three very different stories. A few places this shows up: 1. When your high-level metrics look wonky or divergent, break them out by segment. A flat retention curve often hides one cohort churning out violently and another expanding aggressively. A "meh" NPS usually has one segment of fanatics and one segment of detractors cancelling each other out. The average is a lie. The segments are the truth. 2. When your product is trying to be everything to everyone, you need to tailor it per segment. If your roadmap has SMB founders, mid-market IT buyers, and Fortune 500 procurement all fighting for features in the same backlog, that's three products in a trench coat pretending to be one. Pick the segment you're actually building for, and ship accordingly. 3. When your pricing or positioning feels wrong no matter where you set it, it's because one SKU or pitch is spanning segments with wildly different needs or willingness to pay. Enterprise will pay 10x what a startup will for the exact same thing. A single price point either leaves money on the table at the top or closes the door at the bottom. Segment the packaging. Segment the price. The pattern holds every time. Whenever a business problem is hard to reason about, break the population into segments and look again. Nine times out of ten, the fog lifts. Importantly, you don't need to use standard gender or demographic segments. You can build your own! (And AI is a superpower here). One of the best segmentations in real life was done by @davidweiden at TellMe Networks in the early 2000s. TellMe was selling phone automation software into financial services: a half-billion dollar market, and they had almost no traction. David built a custom segmentation framework called Rifle, which scored every prospect on five weighted criteria. Where the customer was in their buying cycle (engage before the RFP, not after). Whether their long-distance carrier was compatible with TellMe's deployment model. Three more criteria with explicit weightings, including negative scores that disqualified prospects outright. The whole company aligned on the scoring. Sales stopped chasing bad-fit accounts. Product stopped building features for customers who would never close. Marketing stopped spraying the market. Over two years, Rifle drove $20M in ARR inside the qualified segment and took TellMe from a loss to a profit. They literally would have failed without the segmentation. . Founders: when a metric confuses you, when your product feels scattered, when your sales pitch or pricing won't land, segment. Segment, always segment.
