New Product Builds

A greenfield product, AI-native from the first commit.

A greenfield product taken from envisioning through release and maintenance, blue-sky and value-focused, with AI native to the work from day one rather than added once it is already late.

A new product or surface that should be value-focused and AI-native from the first commit.

Is this you?

We need the new product line — but every engineer we have is consumed running the current one.

That sentence is the problem this engagement exists to solve — one problem, solved end to end, not a program that promises everything.

How it usually shows up

  • A validated opportunity waiting on capacity that never frees up
  • A board narrative that needs a new line shipping this year
  • The current platform can't carry the new bet

The engagement

What we do.

New Product Builds is the greenfield engagement: blue-sky, value-focused, and AI-native from day one. A senior-led team runs our process and writes the production code, with your engineers building alongside us in the open.

We take the product from envisioning through release and into maintenance, and because your team helped build it, the patterns, the code, and the way of working all stay with them.

The shift

The second product shouldn't inherit the first one's drag. Greenfield is the one chance to be AI-native from the first commit — we don't waste it.

What’s included

What you keep.

Named deliverables, not a statement of intent. Every one is built with your team so it stays useful after we leave.

  1. Nº 01

    Envisioning

    We shape the product and the first releases around the value they need to create, not a feature checklist.

  2. Nº 02

    Spec-driven build

    Living, machine-readable specs are the system of record, so a second engineer or a coding agent can build straight from intent.

  3. Nº 03

    AI-native platform

    Agent-ready environments and orchestrated coding agents from the first commit, with governance in the platform.

  4. Nº 04

    Release and maintenance

    We ship to production on your stack and stay through early maintenance so the product is genuinely yours to run.

Spec-driven development

One artifact, two kinds of builders.

A prompt disappears the moment it's answered. A spec stays: engineers and coding agents build from it, quality gates verify against it, and what ships updates it. That's what makes speed safe.

  1. Nº 01

    Intent

    The value the product must create: the brief, the goals, the constraints.

  2. Nº 02

    The spec

    Living, machine-readable, in source control. Behavior, constraints, and definition of done become the system of record.

  3. Nº 03

    Build

    EngineersAI agents

    Both build from the same spec, with no retelling and no drift.

  4. Nº 04

    Quality gates

    Tests, evals, and review verify the work against the spec, not against memory.

  5. Nº 05

    Ship

    A production increment traceable back to the intent it came from.

What ships feeds back: learnings update the spec, not just the code, so the system of record never goes stale.

The team model

Your engineers join our team.

This is the mechanism behind “the capability stays” — not a handoff meeting at the end, but how the team is shaped from day one. Every engagement runs on it.

  1. Nº 01

    Day one

    Sigao teamYour engineers

    A senior-led Sigao team arrives with the process and the platform. Your engineers don't get displaced — they get invited in.

  2. Nº 02

    In flight

    One team · one process

    Your engineers join our team — not the other way around. One Engagement Lead owns scope and quality, and everything is built in the open on your stack.

  3. Nº 03

    After handoff

    Your team runs it · we leave

    Because your people co-built the work, they keep running it. The specs, patterns, and operating rhythm stay. The lift outlasts the engagement.

The approach

How we run it.

  1. Nº 01

    Envision

    Define the product, the value, and the shape of the first releases.

  2. Nº 02

    Spec

    Turn intent into living specs that humans and agents can both build from.

  3. Nº 03

    Build

    Ship to production on your stack with your engineers building alongside us.

  4. Nº 04

    Release and maintain

    Launch, harden, and hand off a product your team already knows how to run.

    Easter Seals Greater Houston

    A custom care platform that replaced manual paperwork

    Challenge
    Easter Seals Greater Houston, a nonprofit supporting individuals with disabilities, was burdened by manual paperwork and limited visibility into client data — capping efficiency and the quality of service it could deliver.
    Approach
    Designed a custom digital solution: a web-based application portal (Angular) for families and respite-care tracking, plus a centralized admin portal (Dynamics 365) for staff to manage data, automate workflows, and generate reports.
    Outcome
    Streamlined care documentation, automated workflows, and real-time reporting — improving operational efficiency and enabling faster, higher-impact service delivery at scale.
