Auto telematics for US insurance underwriting and claims: data view (April 2026)
Structured data view of auto telematics vendors serving US P&C insurance. Category splits into three: smartphone-based driving-behaviour platforms (Cambridge Mobile Telematics, Arity, Zendrive), OBD / in-vehicle hardware (Octo Telematics, Azuga), and commercial-fleet-focused solutions (Lytx, Samsara, Geotab).
Cambridge Mobile Telematics (CMT) leads smartphone-based UBI at US tier-1 carriers.
Arity is Allstate's subsidiary with broad carrier partnerships.
Zendrive is the challenger.
Lytx and Samsara serve commercial fleet.
Octo Telematics dominates European OBD-based UBI with US presence.
Which to pick
| Scenario | Recommended |
|---|---|
| US personal lines auto UBI (smartphone-based) | Cambridge Mobile Telematics |
| Carrier already integrated with Allstate Arity | Arity |
| OBD / hardware-based telematics | Octo Telematics or Azuga |
| Commercial / fleet safety | Lytx or Samsara |
| Challenger smartphone SDK | Zendrive |
Ranking criteria
- Named US carrier deployments
- Smartphone SDK vs OBD / hardware model
- Active driver count / miles-driven at scale
- Ownership stability
- Commercial fleet vs personal lines positioning
Most widely deployed smartphone-based UBI platform at US tier-1 carriers. Named carriers: Liberty Mutual, State Farm, Nationwide, Farmers, MAPFRE.

Graph facts
Relationship statistics computed across the Phidea entity graph (tools, carriers, owners, integrations). These facts require cross-referencing multiple primary sources; they are not retrievable from any single vendor press release or analyst report.
- Ownership profile
3 of 5 vendors are PE-held or corporate-subsidiary (Arity = Allstate, Azuga = Bridgestone, Octo = PE). 2 are VC-held independent (CMT late-stage, Zendrive). Samsara is public but fleet-operations-first, not insurance-first.
- Tech-model split
Smartphone-SDK-first vs OBD-hardware-first is the category fault line. US personal lines UBI has shifted almost entirely to smartphone-SDK; OBD is more prevalent in European and commercial-fleet contexts.
- Crash-detection + claims FNOL integration
Most telematics vendors now market crash-detection + FNOL automation as a primary claims-integration feature. Adoption at US carriers' claims organisations is more recent than at underwriting.
