What we build
AI-native products. Enterprise-grade engineering. One team.
Most vendors are either integrators who bolt a chatbot onto yesterday’s stack, or AI startups who have never shipped a payroll system. Tech Box is the team that does both — and uses AI to do it faster.
AI-enabled solutions
LLM copilots, document intelligence, forecasting and computer vision wired into your real workflows, with evaluation, guardrails and cost controls from day one.
ExploreMobile app development
Native iOS and Android or Flutter/React Native — offline-first, secure, store-compliant, and instrumented so you know what users do.
ExploreCloud & DevOps
Azure and AWS architecture, Kubernetes, IaC, CI/CD and observability. We cut cloud bills as often as we grow them.
ExploreLegacy modernization
VB6, classic ASP, WinForms, Access, old PHP — we untangle it, wrap it, and migrate it incrementally with zero big-bang risk.
ExploreDedicated teams
Senior engineers embedded in your process, your tools and your time zone. Scale up in two weeks, down in one.

Why Tech Box
Built for the projects that keep CTOs up at night.
Integration-heavy, regulated, legacy-entangled, AI-uncertain. We have a repeatable way through all four — and a global bench to do it at your pace.
- Senior-only teams. Every engineer on your project has 8+ years; your tech lead has 15+. No bait-and-switch after the sales call.
- Fixed milestones, visible progress. Weekly demos, a live staging environment from week two, and a burn-down you can read without us.
- Your hours, your tools. A dedicated US-hours delivery window, follow-the-sun coverage, daily written updates in your Slack, Jira or Azure DevOps.
- AI with evals, not vibes. Success metrics and an evaluation set before the first prompt; guardrails, logging and cost controls before launch.
- AI-augmented delivery. Every engineer works with AI coding agents inside a governed workflow — specs and architecture first, automated quality gates, senior review on every merge. Typically 30–50% faster to first release.
- Your IP, your repo, your cloud. We work in your GitHub/Azure DevOps and your subscriptions from day one. Walk away any time with everything.

How we work
From “is this even possible?” to production in four steps.
Technical consultation
45 free minutes with an architect — not a salesperson. You leave with an honest read on feasibility, risk and rough size.
Discovery sprint
One to two weeks: architecture, integration map, backlog, delivery plan and a clickable prototype. Yours to keep, even if you build elsewhere.
Build in milestones
Two-week sprints, weekly demos, staging from week two. AI-accelerated implementation with senior review on every merge.
Launch and evolve
Hardening, penetration test, observability, handover docs. Then a support retainer or a dedicated team to keep shipping.
Proven track record
Recent work, with the numbers that mattered.
AI dispatch engine for a 400-truck regional carrier
Replaced spreadsheet dispatching with an ML-ranked assignment engine and driver mobile app. Integrated with the existing TMS instead of replacing it.
38%more loads per dispatcher
11 wksto first production release
HIPAA-ready telehealth app for a home-care network
iOS/Android app for visit scheduling, secure video, e-signatures and offline visit notes syncing to the EHR.
4.8★App Store rating
52%less admin time per visit
Demand forecasting for a 120-store chain
Weekly SKU-level forecasts with explainable drivers, feeding replenishment. Ran shadow-mode for 8 weeks before the buyers trusted it — then they stopped overriding it.

Client reviews
What operators say after launch.
Rated 4.9/5 across 47 verified reviews on Clutch, Google and GoodFirms.
★★★★★
“Three vendors told us our TMS integration was impossible without a rip-and-replace. Tech Box shipped it in eleven weeks and our dispatchers stopped complaining about the software for the first time in a decade.”
★★★★★
“They understood HIPAA better than our previous agency. The offline mode in the nurse app alone saved us hundreds of hours a month.”
★★★★★
“The forecasting model is good, but what impressed me was the eight weeks of shadow mode they insisted on. They cared whether our buyers trusted it, not just whether it worked.”

FAQ
Questions we get on the first call.
What kind of projects does Tech Box take on?
AI-native products and copilots, custom web platforms, native and cross-platform mobile apps, cloud and DevOps engineering, and legacy system modernization. We specialise in complex, integration-heavy work — typically for SaaS companies, enterprises and regulated industries such as healthcare and financial services.
Where is your team and which time zones do you cover?
Tech Box is a distributed senior engineering team spanning North America, Europe and Asia-Pacific. Every client gets a dedicated US-hours delivery window, a named tech lead, and daily written updates, so your project keeps moving around the clock.
How do you scope work?
Every engagement starts with a free 45-minute technical consultation, followed by a short discovery sprint that produces an architecture, integration map, backlog and delivery plan. After that you choose fixed-scope milestones, flexible time-and-materials, or a dedicated team retainer.
Can you work with our existing systems instead of replacing them?
Yes — most of our projects integrate with or incrementally modernize existing platforms (ERPs, TMS, EHR, CRMs, legacy .NET/VB/PHP systems) using API façades and the strangler pattern, so there is no big-bang cutover.
How do you handle security and data protection?
Code review on every merge, dependency scanning, secrets management, least-privilege cloud IAM and penetration testing before launch. We sign NDAs and DPAs, follow GDPR, and have delivered HIPAA-aligned healthcare products. Your IP is yours from the first commit.
Do you build AI features responsibly?
We start with an evaluation set and success metrics before writing prompts, add guardrails and human-in-the-loop review where the stakes are high, log every model call, and make cost and latency visible from the first prototype.
How does AI change the way you deliver?
Every Tech Box engineer works with AI coding agents inside a governed workflow: architecture decisions and specs first, AI-accelerated implementation, automated quality gates, and senior human review on every merge. Clients see the speed; they never see the shortcuts.
Have a hard problem? Good.
Send us the thing the last three vendors couldn't finish. You get a scoped plan, a fixed first milestone, and a senior team — not a sales deck.
