DevTools company playbook.
An early-stage London devtools company building developer-facing infrastructure, SDKs, CLIs, IDE plugins, observability or platform-engineering tooling. The win is reaching predictable PLG-driven MRR + first enterprise contracts while staying ISO 27001 + SOC 2 ready for the procurement gate.

Overview
A London devtools company at pre-seed → Series A typically has £0–£1.6m ARR, 4–14 staff and 14–28 months of runway. The category is brutal — winners reach scale by leaning into open-source distribution + PLG before enterprise, then add SSO / SAML / SOC 2 / VPC-deploy as the procurement gate. The biggest lever is OSS / free-tier funnel design — every signup must auto-instrument time-to-first-value < 5 minutes or activation collapses. The second lever is SOC 2 + ISO 27001 readiness — without them, you cannot close a single Fortune 500 / FTSE 100 logo. This playbook covers operationalising a London devtools company from incorporation through first £40k+ MRR + first enterprise SAML contract.
