Product Engineering

AI-native products and the platforms that run them. Twistag designs, builds and runs them with one senior team, from the first sprint to the last release.

What changes for the business

Ten years, the same engineering bar. Twistag has shipped more than fifty products with senior people on every team and one owner for design, code and operation, so what launches keeps improving after release.

What Twistag builds

Three parts of one working system. Most engagements combine all three.

01 · AI-native product strategy

From concept to a product people use.

New AI-native products and features, scoped around one measurable outcome and tested with real users before the full build.

Discovery and conceptUsers, jobs to be done and the number the product must move.
Prototype in daysClickable prototypes tested with real users.
Conversational surfacesChat-led and voice-led product experiences.
Copilot featuresAI assistance built into existing products.

02 · Custom software development

Web, mobile and APIs built to last.

Full-stack products and internal tools, designed and engineered by the same senior team, on an architecture that stays easy to change.

APIs and servicesAPI design and microservices on AWS or Google Cloud.

03 · Agentic platforms & operation centres

The place where people run their agents.

Agents need a place where people review, approve and correct their work. Twistag builds the orchestration layer and the operation centre around it.

Operation centre UIHuman review, approvals and oversight in one place.
Exceptions and auditException handling and audit trails for regulated work.

Quality and delivery

Senior people, one bar for quality.

Every product is built by a senior team that designs, engineers and runs what it ships. Tests, reviews and documentation are part of the work from the first sprint.

  • Senior teams

    Designers and engineers with years of shipped products behind them.

  • Design and code in sync

    One design system shared between Figma and the codebase.

  • Automated tests

    Unit, integration and end-to-end tests on every change.

  • Accessible by default

    WCAG 2.2 AA as the standard for every interface.

  • Performance budgets

    Speed targets checked before every release.

  • ISO 27001 practice

    Delivery follows ISO 27001 controls, with evidence ready for audits and procurement.

Approach

Every product earns its next release.

Discovery and prototyping are small and fixed in time. The full build starts once real users have backed the idea.

  1. Discover

    Users, jobs to be done and the number the product must move, agreed with leadership.

    2–4 weeks
  2. Prototype and test

    A clickable prototype in front of real users within days, refined until the evidence says build.

    2–4 weeks
  3. Build and launch

    The first release in real users’ hands, measured against that number.

    8–12 weeks
  4. Grow and hand over

    Releases every sprint from real usage, then the code, design system and know-how handed over.

Questions

About Product Engineering.

What does a product build cost?

Cost follows scope: the platforms involved, the integrations, how much design and research is needed and how long the team stays. Discovery takes two to four weeks; a first release usually follows within a few months. A proposal arrives within a week of the first call, with scope, milestones, team and cost.

How soon can work start?

A thirty-minute call, a written proposal within a week, and a discovery sprint of two to four weeks that confirms scope before full delivery starts.

Who owns what is built?

The client owns everything: source code, design files, infrastructure as code, prompts, models and documentation, handed over in full with training for the team.

Does the company need an AI strategy or a data platform first?

No. Twistag works with companies at any stage. Where the data is not ready, data modelling comes first and is scoped as part of the plan.

How does Twistag work with the internal team?

Inside the client’s own repositories, CI, cloud accounts and environments. Twistag can deliver the whole product or join existing squads.

Can the internal team run the product afterwards?

Yes. Build, train and transfer is one of Twistag’s operating principles: engineers pair during the build, every system is documented, and handover walkthroughs happen before the engagement ends.
