Turn IdeasInto Products

Cortexys Product Development covers the full product lifecycle, from MVP design and built-in AI to stable back-office systems.

  1. Fast Launch

    MVP-first strategy

  2. AI Built-in

    AI integrated from day one

  3. Stable Operations

    Back-office & Admin

Core Services

Three core capabilities for rapid product launch and sustainable growth

Fast-track Building

Rapid Product Development

We build MVPs focused on core features in the shortest time, with market validation as the top priority. Lean methodology, zero waste.

  • MVP design & prioritization
  • 2–4 week sprint cycles
  • Lean development methodology
  • Fast market validation

AI Built-in from Day One

AI-Integrated Development

We integrate cutting-edge AI APIs (Claude, GPT, Gemini) as core product features — not bolted on later, but designed in from the start.

  • LLM API integration (Claude, GPT, Gemini)
  • AI-powered automation workflows
  • Smart search & recommendation
  • Generative AI content features

Solid Operations Infrastructure

Back-office & Admin Systems

We build robust admin systems for service operations — settlements, analytics, user management, and all the operational tooling you need.

  • Custom admin dashboard
  • Settlement & payment management
  • User role & permission control
  • Real-time analytics & monitoring

How we work

You see a working build every week.

  • Weekly Demos

    Every week you see a working build, not a status report. If direction drifts, we catch it within a week, not at delivery.

  • Full Handover

    Source code, infrastructure config, and deploy scripts are all yours. Our delivery standard: you can maintain and migrate it without us.

  • Admin Included

    We don't stop at the user-facing product. Every delivery includes a back office for content, inquiries, and analytics.

  • AI-First Design

    We don't bolt AI onto a finished product. Where RAG, agents, or computer vision belong is decided at the design stage, and the data model is shaped around it.

  • Deploy and Observe

    We deploy to self-hosted infrastructure or your cloud, with error tracking and health checks in place. cortexys.team itself runs this way: four subdomains, one codebase, and our own ops dashboard.

Frequently Asked Questions

How the work runs and what you receive, before you commission it.

  • How does development run?

    We work in 2 to 4 week sprints and show progress every week as a working build. If direction drifts, it is corrected within a week.

  • What do we receive at the end?

    All of the source code, infrastructure configuration and deployment scripts. Our delivery standard is that you can maintain and migrate the system without us. A back office for content, inquiries and analytics is delivered with it.

  • Do you handle deployment and operations too?

    We deploy to self-hosted infrastructure or your cloud and set up observability such as error tracking and health checks. cortexys.team itself runs this way, with four subdomains and our own ops dashboard.

  • Can you add AI features to a product that is already running?

    Yes. We integrate RAG and AI agent features into your existing product, working in your repository through your review process. Where needed, our AI division supports the work with model expertise such as sLLM optimization.

    See the AI division →
  • Can you build for on-premise or closed-network environments?

    Yes. When building internal business systems we meet security requirements such as on-premise and closed-network deployment. For enterprise projects we also integrate with existing systems such as LMS and ERP.

  • How is development priced?

    Pricing is agreed through consultation, based on the scale of the project, the team size and the development period. After reviewing your requirements, we lay out the feature scope and sprint schedule and then send a quote. For founders, the proposal is built around an MVP with only the features needed to test the idea, on minimal-cost infrastructure.
