The 2026 reality

AI helps you sketch. We help you ship.

A buyer can ask ChatGPT for a stack, a wireframe, and a budget in 20 minutes. What AI can't do (yet) is the part that decides whether your software actually works in production.

What AI does well

Sketches, drafts, prototypes

  • Lovable, v0.dev, Bolt: usable MVP in days
  • Cursor + Claude Code: features in minutes
  • ChatGPT: first-pass tech recommendations
  • AI-generated wireframes and copy
What we do

Production systems that hold up

  • Pass WCAG 2.2 AA + Section 508 audits
  • Integrate with the 14 systems you already run
  • Survive 100x traffic spikes without downtime
  • Earn a state procurement officer's approval
  • Maintain across 5 years of platform drift

AI-fluent. Policy-aware. Production-grade.

We use AI dev tools where they help us ship faster, and we ship without them when your policy says we should. Your contract sets the rules. We follow them. Read our AI policy →

Common questions

Frequently asked, briefly answered

What kind of projects does OST take on?
Custom software for organizations that face real consequences when software fails: K-12 districts, government agencies, nonprofits, and growing mid-market businesses. Project work and multi-year retainers, depending on what you need.
Are you SAM-registered? Do you bid on government RFPs?
Yes. SAM-registered, woman-led firm. Capability Statement available on request. Site itself meets WCAG 2.2 AA + Section 508, the procurement bar. Past performance includes K-12 (national charter network, 270+ schools), higher ed (Wesleyan College, University of Hong Kong, Kingswood School), and civic-tech.
Do you still work on Joomla, Magento 1, or Drupal 7?
Yes. Most agencies abandoned these stacks. We didn't. Our Bridge Engineering practice keeps your existing platform performing, secure, and ready for whenever you decide to migrate, on your timeline.
How does working with OST actually work?
Our process depends on what you're trying to do. New project from scratch follows one path. Inherited or existing system goes through a different one. Modernization, AI integration, ongoing retainer, and government RFP delivery each have their own steps. See our full process →
