AI-native apps + agents · $5K pilot / $10K standard

AI-native apps and agents,
shipped from spec.

FullSpec turns messy business workflows into production apps, embedded agents, human approval loops, and operating systems your team can actually use.

What FullSpec builds

Apps are the surface. Agents are the operating layer.

We do not bolt a chatbot onto a dashboard. We design the app, the agent roles, the approval loop, and the data trail as one system.

01 · AI-native apps

Interfaces where people work

Dashboards, portals, mobile workflows, internal tools, data products, and customer-facing apps built around the real job.

Workflow UIData modelIntegrationsProduction deploy
02 · Agent systems

Agents where work moves

Slack agents, email agents, research agents, revenue agents, support triage, and operator copilots with clear permissions.

03 · Transformation

Operating systems for AI delivery

Dedicated teams for companies with AI mandates: roadmap, context engine, delivery cadence, governance, and executive reporting.

Agent workers

Every serious AI workflow needs the same backbone: context, UI, tools, approval, logging, and ownership.

Two paths

Have the system built. Or build it yourself.

Same methodology. Same spec engine. Apps where humans work, agents where work moves, and specs that keep both aligned.

The 5-day playbook

Monday spec. Friday system.

Same flow every time. No discovery theater, no requirement docs nobody reads, no agent demos without the app and approval path.

  1. Day 01 · Monday

    Spec

    Discovery call. Workflow → app surface, agent roles, data model, and UX brief.

  2. Day 02 · Tuesday

    Plan + UX

    Architecture brief, screens, approval loops, agent tools. You review before code.

  3. Day 03 · Wednesday

    Build

    AI agents code and draft workflows against the spec while a senior engineer drives.

  4. Day 04 · Thursday

    Test + Guard

    Automated tests, accessibility, security review. We don't ship anything red.

  5. Day 05 · Friday

    Ship

    App, agents, repo, specs, and runbook handed over. 30-day support starts.

Why we can ship in 5 days

We use our own engine.

Every Studio engagement runs on the FullSpec Method. Each phase produces a contextual document for the app, the agent workflow, the data model, and the human approval path. AI agents execute against it. Senior engineers drive.

No estimates. No scope creep. No 6-week kickoff. Just serious workflow transformation, compressed into a scoped build.

How we earn trust

Proof beats hype.

We are keeping the proof layer honest while the first public pilot builds are underway. Example scopes live on the work page.

Locked scope before code
Every Studio build starts with a Monday spec both sides approve: user flows, data model, integrations, acceptance criteria, and explicit cuts.
No open-ended discovery
Artifacts you can inspect
You leave with the repo plus the spec docs: idea, spec, plan, UX, build, test, guard, ship, and sell. The source of truth is yours.
Repo + 9 spec docs
Public proof as pilots ship
The first public case studies will include the scope, walkthrough, stack, and outcome. Until then, we are not presenting testimonials as proof.
Pilot case studies in progress

We're not an agency.

Agencies sell hours. We ship operating software: the app, the agent workflow, the approval path, and the handoff docs.
