Private Software Partners · Est. MMXXVI
Severn Group is a closely held software partnership. We advise founders and established firms on the systems they cannot afford to get wrong, then build them quietly, end to end.
We take a small number of engagements each year. Each is held to the standard of a long-standing client relationship: considered, confidential, and built to last.
The Practice
The foundational decisions about data, infrastructure, and the shape of the system, made deliberately, before a line of code commits you to them.
Software written for your business and no other. Built by a senior team, owned entirely by you, with no dependency on us once it is delivered.
Quiet diligence on the things that carry risk: review, hardening, and the documentation that lets you sleep before an audit.
A retained seat at the table. Technical counsel for boards and founders who want a steady hand to consult before the decision, not after.
Approach
The people you meet are the people who build. No layers, no hand-offs to a junior bench.
We will tell you when not to build something. The cheapest engineering is the work you are talked out of.
Every engagement ends with you owning the system outright: the code, the keys, and the understanding to run it.
The Engagement
A private conversation about the firm, the problem, and whether we are the right hands for it. Under NDA from the first meeting.
Scope, fee, and schedule agreed plainly before work begins. No open-ended billing, no surprises in the third month.
Built by senior hands, delivered with documentation, and handed over in full: yours to own, run, and extend.
The Principal
Managing Partner
James founded Severn Group on a simple conviction: that serious firms deserve the same discretion from their software partner as they expect from their solicitor or their bank.
He leads every engagement personally, from the first conversation to the final handover, and remains the single point of accountability throughout.
