Chicago, IL · Custom Software + AI

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

We pair senior engineers with an AI-accelerated delivery model to ship custom software for Chicago's fintech, logistics, and B2B operators — without the fragile output 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.

Chicago is the deepest fintech, trading, logistics, and B2B SaaS market in the Midwest, anchored by financial-services giants and a strong middle-market software scene from the Loop out through River North and West Loop. Senior hires are six figures, months out, and almost always picked over. The old build-from-scratch model can't keep up. AI changes the math, but only when senior people own the parts AI gets wrong.

On a Chicago trading, fintech, or logistics build, the repetitive 70% — schemas, dashboards, scaffolding, glue — is exactly where AI moves fastest. The 30% that punishes you in production is order-of-operations on a busy order book, time-zone bugs in nightly batches that touch CT, ET, and UTC at once, supervision logging that has to survive a FINRA exam, and supply-chain integrations that fail silently on a partial shipment. Raw AI output gets those wrong without flinching.

We build for Chicago operators — trading-firm internal tools, fintech platforms scaling for compliance, logistics dashboards that cover the rail-and-truck spine of the country, and B2B SaaS rolling out to manufacturers across the Midwest. 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 Chicago trading or logistics build, the failure modes are race conditions under load, timezone drift, and missing supervision trails. Senior review catches them before FINRA or a missed shipment does.

What we build for Chicago companies.

Fintech

Fintech & payments platforms

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

Logistics

Supply-chain & ops platforms

Routing, dispatch, inventory, and visibility tools that replace clipboards and spreadsheets.

Insurance

Insurance & claims platforms

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

Product

SaaS platforms

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

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 in Central Time who own architecture and quality — same business hours as your Loop, River North, or West Loop team — not a junior pool with raw AI output bolted on. We integrate with your existing tools and on-call.

Chicago's senior engineering pool is split across a handful of large employers and a quiet pull from coastal remote roles. Hiring takes months. An AI-native team gets you shipping inside a week, flexes monthly, and doesn't ask for a Loop office lease.

Common questions from Chicago teams.

Do you work with Chicago companies?
Yes — we serve Chicago, Milwaukee, and Indianapolis companies with senior, on-shore engineers in Central Time. Most collaboration is remote-first, with on-site available for kickoffs and key milestones.
Do you work with regulated finance and trading teams?
Yes. We've shipped into SOC 2-audited environments, can architect with FINRA/CFTC supervision concerns in mind, and design data flows that survive audit. We're builders, not certifiers — but we build code that survives your certifier's questions.
Can you integrate with our OMS / EMS / market-data feeds?
Yes. We've built into FIX-adjacent flows, market-data subscriptions, and bespoke broker APIs. We treat market events the way they should be treated: ordered, replayable, and supervised — not as a CRUD endpoint.
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.
