Engagement Playbook →

The five ways we take on, build, and operate infrastructure for clients.

Customers →

Per-customer spaces: their services, decisions, and dependency map. One folder per customer.

Internal →

Propel's own space — internal services, ADRs, and the engineering operating model.

Pattern Library →

Reusable Propel IP with maturity and the tech-adoption matrix across spaces.

Architecture Decisions →

Why we made significant technical decisions — internal log; customer ADRs live in their spaces.

Observability & Logging →

How we monitor infrastructure and protect client logs — uptime, metrics, traces, PII, residency.

Launch

We build a best-practice foundation in your accounts, then hand you the keys.

Accounts: YoursWe: BuildAfter: You run it

See how it works →

Launch & Manage

We build it and run it for you, under an SLA, while your devs ship on top.

Accounts: YoursWe: Build + runAfter: Fully managed

See how it works →

Takeover

Already on cloud? We take over operating it, then stabilise and improve.
