How it works
Most automation freelancers execute a brief. We originate one. We look at how your business runs, identify where time and money are being lost, then design a system that fixes it — on infrastructure you control.
Operational audit
We map your current workflow — where leads come in, how they are qualified, what your team touches manually, and where the bottlenecks live.
System design
We propose a specific automation architecture: which tools, which integrations, which data flows. Scoped clearly before any build starts.
Build and deploy
We build on n8n and self-hosted infrastructure (Hetzner VPS, PostgreSQL, Caddy). Typically live within two weeks. Fully documented.
Monthly retainer
Ongoing maintenance, optimisation, monitoring, and iteration. You can cancel. You always own the system.

The Founder
One Sec Flow is led by Aidan, a London-based operator and automation specialist. The systems we sell are the systems we run internally — the same outreach stack, the same filtering pipelines, the same infrastructure discipline.
The differentiator is not the tooling. It is the ability to look at a business, identify the actual problem, and design a system that solves it — without creating a dependency on us to keep it running.
