U.S. retail vacancy sits at 4.8% while 7,900 stores are closing in 2026. The best boxes are gone before they're listed. Here's the gap no one has filled.
A small biotech just filed a patent on a caffeine-free Excedrin alternative — pointing at a broader gap: OTC categories worth billions, built on decades-old formulations.
Google's aerial imagery launch targets enterprise planners. The actual opportunity is a weekly ranked lead report for local roofers — built on permits, parcels, and storm events.
Austin bounces 85% of ADU permit applications for fixable reasons. PermitFlow and Archistar serve the city side. The builder-facing, drawing-level QA gap is still open.
Quest and Labcorp already run billions in lab work. The gap isn't more testing — it's a $29 plain-English report for the PDF sitting in someone's inbox.
The government just reauthorized SBIR with a new $30M award tier and caps on volume filers — and the workflow layer between technical founders and federal funding still doesn't exist as a real product.
AI-fabricated claim photos are hitting carrier queues at scale — and 99% of insurers say they've already seen manipulated evidence. The mid-market has a gap, and a focused intake layer can fill it.
TikTok Shop hit $23B in U.S. sales. Category buyers at Target, Kroger, and Walmart are still scouting with spreadsheets. The software gap is real.
America's 58,000 independent vet clinics are still running legacy software — Avimark, Cornerstone — while Digitail raises $23M and ScribbleVet gets acquired. The wedge is wide open.
The global secondhand apparel market hits $393B by 2030, and superfakes are better than ever. Resale solved transactions. Nobody has solved portable trust for the seller side.

New Jersey's March 2026 legal notice law created a mandatory compliance workflow for 1,000+ public entities — and no dedicated SaaS product exists to serve it.
Deepfake voice fraud hit $1.1 billion in 2025. Small CPA firms are the softest targets — and no one has packaged the identity verification layer they actually need.
NYC's January 2026 DOB NOW update inserted condo and co-op boards into the renovation permit workflow — creating a mandatory bottleneck that no vertical SaaS has addressed.

AI agents degrade fast in long, messy conversations — forgetting constraints, contradicting themselves, losing the thread. A new B2B SaaS opportunity is emerging around conversational reliability testing, and no one owns it yet.
AI can draft code and memos but still chokes on messy freight invoices and insurance loss runs. A vertical document verification SaaS — built around trust, not extraction — is a wide-open B2B startup idea.
