Fractional CTO services, MVP development, data migration & automation, legacy code modernization, and more, built by a US-based senior team that works directly with B2B companies between 10 and 250 employees.
🔹 Small enough to stay hands-on.
🔹 Experienced enough to get it right.
🔹 Domestic enough that you can actually get someone on the phone.
Services include:
CTO Audit: A fixed-scope technical assessment of your codebase, architecture, and team, so you know exactly what's slowing you down before you commit to anything bigger. Flat rate of $2,500, no commitment to continue.
Fractional CTO Services: C-level technical strategy at roughly 20% of a full-time hire's cost.
MVP Development: One workflow. One result. Fixed price. We scope, build, and ship a production MVP on your real data, not a sandbox demo.
AI Agents & Agent OS: Connect every system you run, normalize data into a shared layer, surface signals before they become problems, and let your team steer agent behavior through natural conversation.
Legacy Code Modernization: We upgrade aging codebases incrementally without a full rewrite, including security patching, technical debt reduction, and architecture improvements. Your releases get less scary, your developers stop dreading the codebase, and your roadmap starts moving again without the business disruption of starting from scratch.
Data Migration & Automation: Move sensitive data, like SSNs and bank details, securely off aging platforms, prune what's outdated, and automate the repeatable work around it.

What makes us different isn't a methodology or a tech stack. It's how we show up: low ego, high accountability, and a genuine interest in the outcome, not just the deliverable.
