Enterprise-Grade Software,
Built to Fit your Business.

Secure, high-performance web and mobile applications. From internal ops tools to customer-facing platforms. MVP to mature product. Built by senior engineers who own the outcome.

Step 1 of 5

YOUR DISCOVERY OUTCOME

Hoyack will come to the discovery call with an MVP scope sized for first paying customers, plus a quarterly engagement roadmap ready for the call.

Positioning

Off-The-Shelf got you 70% of the Way. The Other 30% is the Business.

The SaaS you bought handles the generic parts. It doesn’t know your workflow, your customers, or the rules you’ve built around both. The team works around it instead of in it. Custom software closes that gap, on your terms, with your data.

The off-the-shelf reality

“We’ll just configure it. We’ll just integrate it. We’ll just train the team to use it the right way.”

Six months in, half the team is exporting to spreadsheets and the other half is paying for a feature nobody uses.

What we build

Software designed around your workflow, not the other way around. Owned by you. Deployed where you need it. Maintained by a team that ships in weeks, not quarters.

You get the speed of a startup product team with the discipline of an enterprise engineering org.

What we deliver

Four Disciplines. One Team that Owns All of Them.

Most shops hand you off across vendors for design, backend, infrastructure, and QA. We bundle the four into one team that ships together and keeps shipping after launch.

Responsive, User-Centric Design

Interfaces shaped by how your team actually works, not by what looks good in a Figma demo.

  • UX research with real users, not stakeholder workshops
  • Component libraries that scale across products
  • Mobile-first design where mobile actually matters
  • Accessibility baked in, not retrofitted

Backend with Enterprise-Grade Scalability

APIs and data layers that hold up under load and survive the team that built them.

  • Node, Python, Go, .NET, JVM, whatever fits
  • Postgres, MongoDB, vector stores, event streams
  • API design that downstream teams can actually consume
  • Observability and tracing from day one

Cloud-Native and Hybrid Deployments

AWS, GCP, Azure, on-prem, or all of the above. We architect for where you actually run.

  • Kubernetes, ECS, serverless, bare metal as needed
  • Infrastructure as code, not console clicks
  • Multi-region and disaster recovery patterns
  • Hybrid for regulated workloads

Full QA Automation and Testing Coverage

Tests written by the people who built the feature. CI that fails loudly. Releases that don’t wake anyone up.

  • Unit, integration, and end-to-end coverage
  • Performance and load testing for production paths
  • Security testing on every release
  • Synthetic monitoring after deploy

How we work

Five Stages. Each One Ships Something Real.

No six-month discovery phase before code touches production. We work in tight cycles, shipping a working slice of the product as early as week two so the team can see and react to it.

01

Discovery

One week of deep work with your team. Map the workflow, the constraints, the systems we’re talking to.

02

Design

Working prototypes, not slide decks. Tested with real users before the first line of production code.

03

Build

Two-week sprints with shipped output every cycle. Stakeholders see and use the product as it grows.

04

Deploy

Production rollout with monitoring, alerting, and rollback ready before anyone clicks ship.

05

Iterate

Post-launch support, feature work, or full handoff. We don’t disappear when v1 hits.

The stack

Modern, Proven, Boring. The Way you Want It.

We pick the tools that fit your team and your constraints, not whatever is trending on Hacker News this week. Every choice has a working production system behind it.

What we typically reach for

The List isn’t Exhaustive. The Principle is: Pick the Simplest Tool that Holds Up at your Scale.

When you’d hire us

Common Reasons Clients Pick Up the Phone

MVP / new product

You have a strong idea and need it shipped before the funding window closes.

We’ve taken pre-revenue concepts to first paying customer in 12 to 16 weeks, with the architecture to grow into v2.

Legacy modernization

You have a system that works, mostly. The team that built it is gone.

We migrate from on-prem monoliths, .NET Framework, AS/400, and “the spreadsheet that runs the business” into modern, supportable platforms.

Internal ops

The team is running the business in spreadsheets, Airtable, and seventeen Slack channels.

We replace the patchwork with a real internal tool that fits your operations and pays for itself in saved hours.

Customer platforms

Your customer-facing product needs the speed and polish of a venture-backed competitor.

We ship customer portals, mobile apps, and web platforms with the design and performance to compete with anyone in your category.

Bring Us the Problem.
We’ll Come Back With the Build Plan.

One discovery call. We listen, ask sharp questions, and follow up with a scoped proposal in writing. No twelve-page sales deck, no offshore bait-and-switch.
