Products built to ship, scale,
and keep growing.

Integrated engineering for Web, Mobile, SaaS platforms, and marketplaces. From first commit to production.

What we build

Every product type. One team.

We have built across every major product category. Domain knowledge that stops you making expensive architectural mistakes early on.

Web and Mobile App

Design through deployment and ongoing scale. One team, end to end.

Custom Web Applications

Data-heavy dashboards, portals, and workflow platforms built for performance at any scale.

Cross-Platform Mobile Apps

iOS and Android with React Native. Native Swift and Kotlin when platform features demand it.

SaaS Products

Multi-tenant platforms with auth, billing, RBAC, and architecture that scales without rebuilding.

Marketplaces and Platforms

Two-sided marketplaces with payment splits, vendor management, and search built for discovery.

MVPs

Scoped aggressively, shipped in 6–8 weeks. Real enough for user feedback, clean enough to build on.

UX and UI Design

Design in sprints, not bolted on after. Figma prototypes and component libraries included by default.

Why Carbonteq

You need a product. Most agencies hand you code.

Most dev shops

How it
typically goes

  • Junior developers assigned after sales hands off
  • You see a demo at the end, not progress along the way
  • Architecture optimized for delivery speed, not long-term scale
  • Handover is a repo dump with no documentation
  • No relationship after launch unless you open a new contract
Carbonteq

How we
actually work

  • The same team that scoped your project builds it, from first sprint to launch.
  • Working demos every two weeks so you can course-correct early
  • Architecture reviewed against your 3-year growth plan, not just v1
  • Full documentation and onboarding session as standard
  • Most clients move to a retainer after launch. We plan for that from day one.

FAQs

Common Questions

1Do you take on projects where an existing codebase needs to be continued?

Yes. We start with a codebase audit to understand what we are working with and give you an honest assessment before committing to a timeline. We will not pretend something is in better shape than it is.

2Who owns the code and IP at the end of the project?

You own everything we build for you. Full stop. All IP transfers to you upon payment. We work under NDAs as standard and retain no rights to your codebase after the engagement ends.

3Can you handle design, or do we need to bring our own designer?

We have in-house UX and UI designers who work within engineering sprints. If you have an existing brand or design team, we work within it. If you are starting from scratch, we handle the full process including Figma prototypes and a production design system.
