The biggest industry in the mid-market isn't software. It's construction.

Ask a strategy consultant to name the biggest industry in the Western mid-market and you will hear "software", "healthcare", maybe "business services". The correct answer is the one nobody says: construction. With 18,738 companies in Europe and 19,029 in the US — 37,767 in the $5–300M range under the narrow industry label alone, 63,900 counting the full construction & real-estate sector — it is the single largest industry on both continents. It is also the least covered, least digitised and most family-owned major market we track.

Three numbers that define the opportunity

• $292k revenue per employee. The median construction firm out-earns the median technology company ($159k) per head — asset intensity, not inefficiency, but it means these are real businesses with real budgets, not lifestyle operations.
• 18,290 website visits a year. The sector's median digital footprint is among the weakest we measure — a $30M contractor typically runs a website smaller than a neighbourhood restaurant's. Whoever sells digitisation into this sector is selling into greenfield.
• 16,922 family-owned firms against just 2,336 PE-backed ones in construction & real estate. The succession pipeline here is the deepest of any sector — and the least brokered.

Why the coverage gap exists

Construction is fragmented (no dominant logos to anchor coverage), local (few cross-border champions), and boring (no product launches, no keynotes). Analysts follow attention; attention follows venture capital; venture capital avoids project-based revenue. The result is a systematic blind spot over the largest pool of mid-market companies in the West.

For buyers of data, blind spots are the product. A construction-tech vendor, a building-products manufacturer, an insurer or a search fund working this sector competes against far fewer well-armed rivals than anyone selling into SaaS.
