AI Services
We build AI that goes into production and stays there.
Four areas, all of them running today for real users.
01 Model Evaluation and AI Governance
We build AI you can answer for. Every system we deliver comes with human approval on the decisions that matter, a record of what the AI said and where the answer came from, role based access, and a running measure of what each task costs.
What sits under it
The dual model review in our own bid system, where two frontier models analyze the same document independently and a human reads anything they disagree on. Role based access, escalation rules, audit trails and source traceability in the AI assistants we build for education and government. Accessibility to Section 508 and WCAG standards treated as a requirement, not a later phase.
02 Domain Specific Agent Systems
Generic AI knows the internet. Useful AI knows your admissions calendar, your product catalog, your filing rules. We build AI systems that learn how your organization actually works and plug into the systems you already run.
What sits under it
AI assistants for schools, colleges and public agencies, answering across web chat, SMS, email, WhatsApp, Instagram and student portals in more than 90 languages. AI powered search and assistants built into ecommerce catalogs. The multi agent system that runs our own bidding operation from screening through submission checks.
03 AI Automation
Work that used to take a person an hour should take a few seconds. We automate the repetitive parts of your operation with AI, and we keep a person in the loop wherever the output matters.
What sits under it
A two way document engine for a real estate investment platform that turns offering memoranda into structured property listings and builds documents back out of listing data. Product listing generation for a power sports retailer, where a few basic fields become a full listing with description, image, SEO title and metadata.
04 Agentic AI Optimization
Most teams are paying two or three times what they need to for AI. We go through your prompts, your caching, your model routing and your retry logic, and we bring the bill down without giving up quality.
What sits under it
Prompt and response caching, batch processing for work that is not urgent, routing simple requests to cheaper models and hard ones to stronger models, cutting token waste, and fixing retry storms. Typical savings run 50 to 60 percent. Our own systems are built the same way, with cost logged on every run.
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 →
