IoT Software Development Company in London, built to ship.

You cannot recall the firmware

Over-the-air update has to work before the first unit ships, including staged rollout, rollback and what happens when power is lost mid-flash. A fleet without reliable OTA is a fleet you can never fix. We track more than thirty thousand vehicles, and the update path was designed before the telemetry was.

Disconnection is the normal state, not the error state

A device in a basement, a tunnel or a dead cell is offline routinely. It buffers locally, it reconciles on reconnect, and the server distinguishes a device that is quiet from a device that is gone. Treating every gap as an alert produces alarms nobody reads.

Time-series volume breaks ordinary databases

Thousands of devices reporting every few seconds becomes billions of rows quickly. Retention, downsampling and what a query actually needs at each age of the data are design decisions taken before the first row lands, not after storage costs surprise someone.

Provisioning and identity at scale

Every device needs a credential, a rotation path, and a way to be revoked when it is stolen or decommissioned. Shared secrets across a fleet are the failure that turns one compromised unit into all of them.

Working overlap

3.5 hours a day

Five and a half hours behind Surat in winter, four and a half in summer. The overlap is our afternoon and their morning, roughly 14:00 to 17:30 IST. That is enough for a daily call and not enough for continuous pairing, so the working agreement has to be written down rather than assumed.

The law that applies

the UK GDPR and the Data Protection Act 2018

The UK holds an EU adequacy decision, so EU-to-UK transfer is straightforward, but transfers onward to India need their own basis. In practice that means standard contractual clauses and a transfer risk assessment, and it is far cheaper to put those in place at contract signature than at go-live.

Where the data can live

AWS eu-west-2, Azure UK South and Google europe-west2 all sit in London. Since Brexit the region choice carries a second meaning: EU customer data in a London region is a transfer, not a domestic hop, and a client with European users will ask which region before they ask about the roadmap.

Sectors that dominate

Financial services and the fintech layer around it dominate, with insurance and the Lloyd's market, legal technology, and media close behind. A striking share of software buying here is by a regulated entity even when the product itself is not regulated.

The mistake we see most

The supplier assurance process is routinely longer than the build. A security questionnaire, evidence of insurance and often a penetration test report arrive before contract, and teams that scheduled the project from the kick-off date rather than from the assurance start date are late before they write a line. Ask for the questionnaire in week one.
