What we build

Three lines of work, one team behind all of them.

Most engagements start with one and grow into the others. You are never handed to a different group when the phase changes.

Custom software development

Platforms and internal tools built for how your business actually works.

  • Enterprise platforms and internal tooling
  • Full lifecycle, discovery through production
  • Built to be maintained, not just shipped

  • Incremental migration instead of a rewrite
  • Integration with existing and legacy systems
  • Architecture that removes the bottleneck

Tell us what you are dealing with. In two weeks you will have a plan for it.

How we work

It starts with two weeks and a written plan.

Every engagement begins the same way. We map what you run, find what is actually blocking the business, and hand you a sequence. You own it whether or not we build.

The Two-Week Discovery

Fixed fee of $7,500, credited in full against the build if you go ahead. Two weeks, and you leave with a plan you could hand to anyone.

  • A map of your current architecture and its limits
  • The constraint that is actually costing you
  • What to build first, and why that order
  • A written plan, yours to keep

Credited against the build. Yours either way.

Regulated environments

We work as a Business Associate under HIPAA and sign your BAA before any access.

Read our security practices
  1. Phase 1

    Discovery

    Two weeks to find out what is actually wrong.

    • Current architecture and its limits
    • Where the business is actually blocked
    • Automation worth the effort
  2. Phase 2

    Architecture

    A plan specific enough to hand to anyone.

    • Target architecture with trade-offs written down
    • Roadmap tied to business outcomes
    • The smallest slice that proves it
  3. Phase 3

    Build

    Working software in front of users, in increments.

    • Development against the agreed architecture
    • Integration with existing and legacy systems
    • Automation and AI where they earn their place
  4. Phase 4

    Operate

    It keeps working after we hand it over.

    • Monitoring and performance in production
    • Iteration driven by real usage
    • Handover to your team

Selected work

What we were brought in to fix

A sample across company sizes and sectors.

Enterprise software company

B2B SaaS

Platform rebuild

Challenge

A core platform had outgrown its architecture. Every release had become risky.

What we built

Rebuilt around a modular architecture, migrated in slices so the product never went dark.

Outcome

  • Releases went from an event to a routine
  • Risk carried by the test suite, not by people

Multi-channel retailer

Retail

Data & ETL

Challenge

Sales, inventory, and fulfilment data never agreed. Reporting was assembled by hand.

What we built

Built pipelines that consolidate the operational systems into one source of truth.

Outcome

  • Every channel reads the same numbers
  • Buying decisions made against today, not last week

Industrial manufacturer

Manufacturing

Automation

Challenge

Back-office work depended on people moving information between systems.

What we built

Automated the handoffs, keeping people on the decisions that need judgment.

Outcome

  • Nobody retypes data between systems anymore
  • The team spends its day on exceptions, not transfers

Financial services firm

Financial services

AI in production

Challenge

Analysts read documents by hand to find what the business needed quickly.

What we built

Built document processing into the existing workflow, with analysts reviewing what the model flagged.

Outcome

  • Analysts read what was flagged, not everything
  • Every automated decision leaves an audit trail

Your system is not a template. Neither is the plan for it.

Why ZIONN

The difference shows up in month six.

A small senior team, working to international engineering standards, accountable for what happens after launch.

Full lifecycle ownership

The engineers who scoped your project are the ones who build and run it.

  • Discovery through operation in one team
  • No requirements lost in a handoff
  • Accountable for the outcome
One team, end to end

Architecture-first

Six months in, you can still find out why something was built that way.

  • Trade-offs documented, not assumed
  • Designed for your team to maintain
  • Technical debt taken on knowingly
Decisions on the record

AI where it earns its place

AI that survives contact with your real data and your real workflow.

  • Inside existing workflows, not alongside
  • Data orchestration as the foundation
  • Human review where judgment matters
Integrated, not experimental

Nothing locks you in

Stop after any phase and you still own something that works.

  • Stop after any phase with something usable
  • Code and documentation any team can pick up
  • HIPAA engagements under a signed BAA
No lock-in
  • Full lifecycle ownership
  • Architecture-first
  • AI in production
  • Nothing locks you in
