SPEC-DRIVEN DEVELOPMENT · AI PLATFORM · SOFTWARE LIFECYCLE

From requirement to production, with AI that doesn't improvise.

Our AI platform supports the entire software lifecycle with Spec‑Driven Development: every feature starts from a verifiable specification, and agents running low-entropy models turn it into traceable code, tests and documentation. Higher-quality releases, in far less time.

SPEC-DRIVEN DEVELOPMENT · LOW-ENTROPY AI

Specification first. Code second.

In Spec‑Driven Development (SDD) every feature begins with a verifiable specification: what it must do, which acceptance criteria it must meet and under which constraints. That specification is versioned with the code and is the project's single source of truth.

Our AI platform turns it into code, tests and documentation using low-entropy models — bounded, predictable and traceable — and verifies every release against it. Your team spends its time deciding what to build; the platform spends its time building it right.

THE SDD LIFECYCLE

Six phases, one source of truth.

  1. 1

    Specify

    Team + business

    Requirements, acceptance criteria and constraints in a specification versioned alongside the code: the single source of truth.

  2. 2

    Design

    Team + agent

    A technical plan derived from the spec — architecture, API contracts and data model — reviewed before building.

  3. 3

    Plan

    Agent · team reviews

    The spec is broken down into small, verifiable tasks, each linked to the criteria it satisfies.

  4. 4

    Implement

    Agents

    Agents generate code, tests and documentation from the spec and the repository context.

  5. 5

    Verify

    Automated + human review

    Every change is checked against the acceptance criteria, with security analysis and human review as the final check.

  6. 6

    Deploy & evolve

    Pipeline + team

    Continuous integration and delivery. Every change starts in the spec; the rest is regenerated and verified again.

A business change doesn't start in the code: it starts in the specification. Code, tests and documentation are updated and verified against it again.

LOW-ENTROPY MODELS

AI that doesn't improvise: same specification, same result — no scatter, no rework.

Spread of results for the same requestA free-form prompt produces widely scattered results; a specification with bounded context concentrates them around the expected behavior.Specified behaviorSpec + bounded contextFree-form promptPossible results for the same request
THE AI PLATFORM

An AI platform that serves your software lifecycle.

Engineering agents for every phase — specification, design, implementation, testing, review and documentation — working on your repositories and standards, deployed on your infrastructure: cloud, private cloud or on-premise. The platform executes; your team decides and oversees.

Deployed on your infrastructure · under your brand · overseen by INNTECI
SECURITY & GOVERNANCE

Security isn't a feature. It's the starting point.

No credentials in the agent

Each agent has its own identity, separate from the user's, with permissions scoped to every call.

Full traceability

A tamper-proof record written by the infrastructure that executed, not by the model: evidence an auditor can accept.

Data never leaves the perimeter

Hosted, private cloud or 100% on-premise with open models. Compatible with banking secrecy.

Bounded cost, no shadow AI

Budgets per team, workflow and agent. A governed, audited system instead of company data in personal accounts.

How we oversee it: INNTECI defines the controls and audits compliance using frameworks aligned with the EU AI Act (Regulation (EU) 2024/1689) and ISO/IEC 42001. The platform produces the evidence; our AI Governance team reviews it at the frequency your risk level requires.
THE OUTCOME

Higher-quality releases, far more efficient.

QUALITY

Fewer defects in production

Every release is verified against the acceptance criteria before it reaches human review.

EFFICIENCY

Less rework

Ambiguity is resolved in the specification, not in the third iteration of the code.

TRACEABILITY

From requirement to deployment

Every change points to the criterion that justifies it: audit-ready evidence.

MAINTAINABILITY

Documentation that never goes stale

Spec, code, tests and documentation evolve together, in the same repository.

WHERE WE APPLY IT

From new products to legacy systems.

PRODUCT

New digital products

From idea to first production release, with the specification as the guide from day one.

LEGACY

Legacy code modernization

We specify the system's current behavior and renew the code piece by piece, without a big-bang core migration.

INTEGRATION

APIs and integrations

Contracts as specification: services, clients and contract tests generated consistently.

MAIN FOCUS

Regulated environments: banking and insurance

Requirement–code–test traceability, data inside the perimeter and human oversight on every release.

On critical systems we start in shadow mode: agents work alongside the team until their value is proven.

BUSINESS LINES

Five business lines, one method.

All of them share the same method — the SDD lifecycle, measured quality and human oversight — and each covers the phases where it adds the most value.

Digital product development

Consistent, usable and scalable experiences.

We design and build digital products end to end with Spec‑Driven Development: user research, design systems that keep every channel consistent, and architectures ready to grow without being rewritten.

  • Spec‑Driven Development
  • Product discovery
  • UX/UI and design systems
  • Web and mobile development
  • Cloud architecture
  • QA and CI/CD
LIFECYCLE PHASES COVERED

Cybersecurity

Security built into the lifecycle, not bolted on at the end.

Security requirements are part of the specification: threat modeling during design, automated analysis on every change and penetration testing before every significant release.

  • DevSecOps
  • Vulnerability assessment
  • Penetration testing
  • Compliance: ISO 27001, DORA, NIS2
  • Business continuity
LIFECYCLE PHASES COVERED

Business consulting

Specialists in business verticals and new solutions.

We know how banking, insurance and financial services really operate. We turn that knowledge into precise specifications, product roadmaps and specialist teams that work as part of yours.

  • Banking and financial services
  • Insurance
  • Product strategy and roadmap
  • Specialist teams and PMO
  • Process optimization

  • Customer support
  • Service level agreements
  • Progressive automation
LIFECYCLE PHASES COVERED

Agentic Automation & AI Governance

The platform that turns specifications into verified software.

Our AI platform and its engineering agents, together with the control frameworks — AI Act, ISO/IEC 42001 — that keep them operating within the defined course. Every automation comes with its oversight.

  • Engineering agents
  • Low-entropy models
  • Legacy code modernization
  • AI governance and compliance

ABOUT US

Efficiency and quality don't compete. They are the same method.

INNTECI was founded in 2010 on one conviction: software gets expensive when quality arrives late. Today that conviction has a method and a tool: Spec‑Driven Development and an AI platform that verifies every release against its specification.

We work from Spain, Costa Rica, Mexico and Panama with teams that become part of yours: short cycles, frequent releases and full visibility of progress. More than 1,275 projects later, the principle hasn't changed.

The specification leads

Requirements and acceptance criteria written before the code and versioned with it.

Verifiable quality

Tests, security and code review on every change, not in a final phase.

Secure by default

Controls inside the pipeline instead of last-minute audits.

Human oversight

AI executes; decisions and the final review always belong to people.
