Plano, TX · Custom Software + AI

Custom software for Plano — built the AI-native way.

We pair senior engineers with an AI-accelerated delivery model to design, build, and ship custom software far faster than a traditional shop — without the fragile, unreviewed code that gives AI a bad name.

Senior-only engineering · AI-accelerated delivery · you own 100% of the code

AI changed the economics of custom software. We rebuilt our process around it.

Plano anchors the corporate-HQ heart of north DFW — home to Toyota Motor North America, JPMorgan's Plano campus, Liberty Mutual, Frito-Lay, and a deep enterprise SaaS and fintech bench. Senior hires are six figures, months out, and picked over by Fortune-500 employers and the venture-backed challengers around them. AI changes the math, but only when senior people own the parts AI gets wrong.

AI is genuinely good at the repetitive 70% of software work: scaffolding, boilerplate, CRUD, first-draft UI, test stubs, glue code. It is dangerously unreliable at the other 30%: architecture, security, edge cases, and knowing when its own output is wrong. Teams that ship raw AI code learn this in production.

We build for Plano operators — fintech and payments platforms scaling toward compliance, enterprise SaaS shipping into Fortune-500 buyers, insurance and claims platforms, internal corporate tools, and modernization of decades-old enterprise stacks. Our model: AI handles scaffolding and the repetitive 70%; a senior engineer owns architecture, security review, and signs off on every change.

Show, don't tell

AI writes the first draft. A senior engineer signs off.

Every change runs through review for security, tests, and architecture before it ships — that review is the product.

On a Plano enterprise build, the failure modes are batch-job edge cases, SSO claim assumptions, and SLA tail latency on legacy integrations. Senior review catches them before procurement or month-end does.

What we build for Plano companies.

Fintech

Fintech & payments platforms

Customer-facing apps, ledgers, and risk pipelines for regulated, data-heavy products.

Product

SaaS platforms

Multi-tenant products with auth, billing, and dashboards — MVP to scale.

Insurance

Insurance & claims platforms

Underwriting tools, claims automation, and broker portals for carriers and InsurTechs.

Modernize

Modernization

Move legacy systems onto a modern, maintainable stack — incrementally, no big-bang.

AI

AI applications

Copilots, RAG, search, and agents grounded in your data, with guardrails and evals.

Internal

Internal tools & copilots

Operations tooling that replaces the spreadsheet-and-tribal-knowledge workflow.

Senior, on-shore, AI-accelerated

A senior team that moves at AI speed.

You work with senior engineers who own architecture and quality — not a junior pool with raw AI output bolted on. We communicate in Central Time and integrate with your tools and cadence.

Plano's senior engineering pool is concentrated around Toyota NA, JPMorgan, Liberty Mutual, and the broader Legacy West and corporate-HQ ecosystem — three-to-six months to hire and quietly poached by remote coastal roles. An AI-native team gets you shipping this week, flexes monthly, and doesn't need a Legacy West office.

Common questions from Plano teams.

Do you work with Plano companies?
Yes — we serve Plano, Dallas, Irving, and Garland companies with senior, on-shore engineers in Central Time. Most collaboration is remote-first, with on-site available for kickoffs and key milestones.
Can you integrate with our SSO, ERP, and CRM?
Yes. We've built into Azure AD/Entra, Okta, SAP, NetSuite, Salesforce, and a long list of more obscure enterprise integrations. We treat your existing identity and system-of-record as the source of truth, not something to work around.
Is AI-built software production-ready?
Yes — when a senior engineer reviews every output, adds tests, and hardens it. The horror stories come from shipping raw AI code unsupervised. We don't, and we support what we ship.
Will we own the code?
100%, from day one. We deliver to a repository you control — no proprietary platform, no lock-in.
How fast can we start?
Usually within days. A short scoping call defines the build, the timeline, and a fixed quote.
Can you work with our existing team?
Yes — we augment in-house teams, review their work, and set standards, or run the build end to end. We flex to how you work.
