Win the tender. The work pushes to your SIM.
A SIM-card-first job network for UK trades and contractors. We win government and private tenders. Jobs ping straight to crews running a EN/ABEL Trade SIM. Tenders pay up front — trades paid on signed completion.
From tender to paid in four steps.

Every trade pain point, mapped to a capability and a verifiable source.
Nothing here is marketing fluff. Each row cites either a UK regulator/government source or an internal repo file. See the appendix for the full source list.
| Pain point | Capability | How it solves it | Refs |
|---|---|---|---|
| Lost signal on big sites, basements, steel-frame builds. | DDRR auto-switch across four UK carriers. DDRR · Refresh | Detect weak RSRP → defer non-critical traffic → refresh to strongest carrier → reconnect with forward secrecy. | [1][9][12] |
| Job dispatch must reach the right trade in the right postcode in seconds. | ENIGMA-signed dispatch over multi-network SIM. ENIGMA · Encryption | Sealed payload, geofenced match, 30-second accept window, fall-through to next-best trade. Cannot be spoofed by aggregators. | [13][6] |
| Proof-of-work disputes — did the plasterer actually finish? | ENIGMA Audit pillar with hash-chained evidence. ENIGMA · Audit | Each photo upload sealed into the audit log with row_hash / prev_hash. Tamper-evident in court. | [11][13] |
| Cash-flow gap between tender award and trade payment. | Tender paid up-front; trade paid on signed completion. | Payout state machine fires only on a sealed completion event. No 60-day waits. | [5][8] |
| Mobile bills £200–£300/month per site worker. | Multi-network Trade SIM at £50/month. | One SIM, four UK networks, DDRR picks the best. Sub-£50 vs typical site-staff bills. | [2] |
| Storms, incidents, carrier outages take crews offline. | ENIGMA mesh — every Trade SIM is a node. ENIGMA · Resilience | Off-grid routing across long-range radio, BLE and TCP fallback. Crews stay reachable when the carrier is down. | [7][10] |
| MOD / sensitive sites need no-address comms. | ENIGMA Identity + Encryption. ENIGMA · Identity | No persistent address, ephemeral keys, bearer-agnostic — exceeds typical operator security posture. | [13] |
| Sub-contractor onboarding, MDM, lost devices. | EN/ABEL MDM + DDRR managed config. | Android fleet today, iOS once ABM enrolled. Wipe, lock, rotate, all from the contractor dashboard. | [12][9] |
| Tender discovery latency — first-mover wins. | Live Contracts Finder + Find a Tender feed. | Server-fn polls the gov portals on a schedule; trades get a ping the moment a relevant notice goes live. | [3][4] |
Run your sub-contractor fleet on one mesh.
MDM-managed Trade SIMs across your sub-contractor base. ENIGMA-signed proof-of-work uploads, sealed in an audit chain that holds up in court. DDRR keeps crews online inside basements, steel-frame builds, and during storms.
