The operating system for construction.
Spun handles invoicing, quotes, and Verifactu-ready compliance — so builders, plumbers, and electricians can focus on what they do best.
First, we run their back-office. Then we replace the services they pay €70–150/month for.

See Spun in action
A 90-second look
A regulatory deadline is opening the market
Spain's Verifactu mandate requires 300,000+ construction entities to adopt compliant invoicing before Jan 2027. It's not a trend — it's a law with a date. Spun is designed to adapt to the final Verifactu requirements.
The market
Built for the businesses nobody serves
construction entities in Spain alone
are micro-businesses — the exact profile Spun is built for
use no software today. Verifactu forces them to start

The thesis
The back-office is Ring 0
The operating system for construction comes after the habit is built.
The professional’s operating system
Quotes, invoicing, projects, collections, KPIs.
Starting price: €14.90/month — the anchor.
Professional ↔ client coordination
Connecting the professional to their end client.
Network effects begin at ≥500 active professionals.
Replacing the services they already pay for
Automated back-office services they currently outsource: accountancy, permit licenses, H&S compliance.
The ceiling: €100–300/month — what they already spend today.
