IoT company playbook.

A London IoT company shipping connected devices + cloud + mobile / web app as a single product (smart building, asset-tracking, industrial sensing, consumer smart-home). The win is reliable fleet telemetry + OTA updates at 1k–50k connected devices with strong unit economics (device gross margin + recurring connectivity / SaaS ARPU).

Overview

An IoT company is hardware + cloud + connectivity as one product — three cost stacks, three failure modes. The biggest lever is fleet-side gross margin: a £1.20 / device / month cellular cost across 20k devices is £288k / yr that must be passed through or absorbed. The second lever is the EU Cyber Resilience Act (CRA, enforced 2027) — any connected device sold in the EU must ship with security-by-design, vulnerability disclosure + 5-year patch commitment. UK-only sales escape CRA but most IoT buyers expect parity. This playbook covers operationalising a London IoT company from first PoC fleet through 1k–50k connected devices and £500k–£5m ARR.
