NBS: The Unseen Backbone of UK Construction
How a 336-person company manages $135M revenue in a niche B2B market
While the world obsesses over flashy PropTech startups, NBS (formerly the National Building Specification) quietly powers the technical backbone of the UK construction industry. With 414,000 monthly visitors and $135.7M in revenue, this isn't a startup—it's an entrenched infrastructure play serving architects, engineers, and manufacturers.
"NBS doesn't just sell software—they own the specification language that architects use to describe buildings."
The Specification Monopoly
NBS isn't competing with Autodesk or Procore—they're the layer beneath. When an architect specifies 'NBS Chorus' or 'NBS Source,' they're using a de facto industry standard. The 61% organic search traffic proves their moat: people aren't just buying software, they're searching for the industry lexicon itself. The 'nbs' keyword alone drives 89,220 monthly searches—more than many SaaS companies' entire keyword portfolios.
The BIM Library Flywheel
Their keyword strategy reveals a brilliant product-led growth engine: 'nbs bim library' (810 monthly searches), 'nbs source' (1,270), and 'nbs chorus' (620) aren't just search terms—they're entry points. Each library search pulls manufacturers deeper into the ecosystem, creating a network effect where more manufacturers = more specs = more architects. The Trustpilot rating of 2.6/5 suggests friction in this model, but the traffic numbers show the utility outweighs the pain.
The tech stack tells a story of pragmatic evolution. jQuery and Bootstrap suggest legacy systems, but the presence of PWA and Tailwind CSS indicates modernization efforts. They're not rebuilding from scratch—they're incrementally improving a cash-generating machine. The 33% direct traffic is particularly telling: when architects need specifications, they don't browse—they go straight to NBS.
- Traffic concentration: 62.8% from 'undefined' countries (likely UK-dominated) suggests massive domestic dominance with limited global expansion
- Revenue per visitor: ~$39 annually (assuming uniform distribution) indicates high-value B2B conversions
- Employee efficiency: $404K revenue per employee—exceptional for a B2B SaaS platform serving a traditional industry
NBS is infrastructure, not software
While competitors fight for feature parity, NBS owns the language of construction. The 2.6/5 rating proves they're indispensable despite friction—true monopoly behavior. For investors, this is a boring, cash-generating machine. For founders, it's a masterclass in building unsexy, unassailable moats.

Fantastic support
Both Katie Wilson and Daniel Muckle are a real testament to this company, they have provided us with an outstanding level of support throughout the last 18 to 24 months assisting us in bringing everything up to date and showcasing the platform and how it can assist our specification and marketing needs. With no task too big or small, they have both supported us in bringing our user area and supporting documents up to scratch and improved our quantity of specifications by almost double. Huge thank you to them both
