RSMsoft is a small, senior team that designs, builds, and operates production software for founders and operators. No PM layer, no offshore relay — a brief goes to the same person who writes the first pull request and stays to maintain it.
Six practices, one team. We take on a handful of engagements each quarter — this is what we do well enough to put our name on.
Durable services, readable code, honest failure modes. Boring, well-understood tools that keep running in production.
Admin panels, operator dashboards, and back-office UIs for the teams that actually run the business after launch.
Web apps built like infrastructure — fast, accessible, and honest about state. Designed with the team, not after it.
Money movement you can explain to an auditor. Webhook-safe, idempotent, reconcilable — the unglamorous work done well.
You shouldn't need to read a new YAML file to ship a fix on a Tuesday. Infra we can both operate — and a runbook you can read.
LLM features that are cheap, observable, and grounded in your data — with an eval harness you can actually trust.
Weekly demos, fixed scope, fixed fee. A signed scope with a ship date — and a short list of things we've explicitly agreed not to build.
A 60-minute call. You describe the problem. We push back where we disagree and write it up the same week.
A signed scope with a fixed fee, a ship date, and a short list of things we've explicitly agreed to not build.
A senior engineer, weekly Friday demos, every commit reviewed, every decision in writing. No PM layer.
We stay. An optional monthly retainer to own on-call, paging, and the small fixes nobody wants to do.
We're not a body-shop, not a platform, not a certified-partner-of-somebody. Just engineers who ship the code they promise.
The engineer who hears the brief writes the first pull request — and stays to maintain it. No handoff, no broken telephone.
A signed scope, a ship date, and a short list of things we've agreed not to build. No surprise invoices. No meter running.
Launches are easy. Running in production is the work. A monthly retainer covers the real code — not sprint theatre.

Custom AI solutions for the enterprise — deployed anywhere, at any scale. Bring-your-own-model serving, managed multi-cloud deployments, and turnkey integration into the data platforms teams already run.
AI-native email security fabric for the Fortune 500 — BEC, account takeover and brand impersonation that legacy Secure Email Gateways can't see. API-native deploy in twenty minutes, post-delivery remediation, built for the SOC.
Turn-key lead program for US real-estate agents and investors, with an exclusive research layer that does the heavy lifting before the first call.
Infer gender and nationality from a first name at scale — a developer-grade JSON API plus CSV and XLSX batch processing, with six corpora under continuous observation.
National real-estate mentoring platform — off-market deal discovery, investor education, and a content stack that's served thousands of students.
Briefs are read by a human — usually me. One paragraph is enough. If we're not the right team, we'll say so.
We're a small team in Denver with an engineering desk abroad. Replies within one business day.
One paragraph is enough. What are you building, what's the constraint, and what does success look like in 90 days?
