What we
Do best.
Custom XR Development
Full-cycle development of VR, AR, and Mixed Reality systems from architecture and prototype to production deployment. Whether it’s high-fidelity physics simulations, multiplayer LBVR arcade experiences, training tools, educational platforms, research projects, AI powered experiences or historical reconstructions, if it’s XR we’ve got you covered.
Prototype & Idea Validation
Not sure if your XR concept is technically feasible or worth the investment? We build a focused prototype that validates the core interaction before any full development commitment. Fast, scoped, and designed to give you the answer you are looking for.
Project Blueprint
A fixed-fee 1-2 week engagement that produces your full project plan before a single line of development is written. We run working sessions, map the architecture, define milestones with scope and pricing per stage, and deliver a complete proposal. You know exactly what you're getting and what it costs before committing to development.
XR Consultancy
Advisory and hands-on technical guidance for XR projects at any stage. Whether you're exploring a new idea, working through challenges in an existing build, or looking for a second opinion on technical decisions, we're here to help. Support can be purely advisory or more hands-on, depending on what you need, and is available as one-off sessions or multi-session packages.
What to expect when working with us
Simple Process.
Zero Surprises.
- 01
Free Discovery Call
A no-commitment call to understand what you're building and whether we're the right fit. We give you real technical feedback before anything is signed. No fee, no obligation.
- 02
MNDA & Project Blueprint
We sign an MNDA, then run a paid 1-2 week engagement to produce your full project plan: architecture, technology choices, milestone breakdown, timeline, and fixed pricing per stage. You know exactly what you're paying before development begins. Once approved, it becomes the contract for the entire build.
- 03
Milestone-based Development
Development runs in defined milestones, each with a fixed scope, fixed timeline, and fixed price agreed before work begins. The first milestone typically delivers a working prototype. Each subsequent milestone builds toward the final product. Changes outside defined scope are quoted and approved in writing before we touch them. That means no surprise invoices, no hidden costs, just complete transparency from start to finish.
- 04
QA Testing & Delivery
Before launch, we put the product through thorough quality assurance to catch issues, refine the experience, and ensure everything performs as expected. Once approved, we deliver the polished, production-ready version of the project.
- 05
Maintenance & Support
Post-launch, we offer a monthly retainer covering ongoing support: bug fixes, platform updates, store releases, and guaranteed response time. The retainer covers keeping things running, new features are always scoped as separate milestones. The arrangement is month-to-month, with no long-term commitment or lock-in.
Testimonials
What People Say
About Us.
“I worked with Kortex on a Multiplayer 3D Unity Game and I was impressed by all the hard work. In little time we had something running, and they definitely knew what they were doing. If I ever have another project similar I would gladly work with Kortex again.”
“Kortex is one of a kind. Extremely patient and so easy to work with. I will definitely recommend without reservation. I will hire them again.”
“Great company. I hired them again to do the rest of the work and they did a great job. Good Work. Good Dedication. Good understanding of the Needs with Just the required amount of Communication. Thanks. Will Look Forward to contunue to work together again.”
“Good job done”
“Working with Kortex was an absolute pleasure! Throughout the project they communicated very quickly and effectively and were flexible in their approach. Were extremely helpful in suggesting options for us. Would absolutely work with Kortex again.”
FAQ
You got questions?
We have answers.
How does your pricing work?
We use three models depending on the phase. The Project Blueprint is a fixed fee for the planning engagement. Development is milestone-based and each milestone has a fixed scope, fixed price, and fixed timeline agreed before work starts. Post-launch maintenance runs on a monthly retainer. The rule is simple: if it's new, it's a milestone. If it's keeping something running, it's a retainer.
What is the Project Blueprint and why is it paid?
A 1-2 week engagement before any development commitment. We run working sessions, map the full technical architecture, break the project into milestones, and deliver a complete proposal with timeline and fixed pricing per stage. By the time the Blueprint is done, you know exactly what you're building, how long it takes, and what it costs. No surprises down the line.
What's the difference between a milestone and a retainer?
Milestones fund output a defined deliverable at a fixed price. Retainers fund availability: ongoing support, bug fixes, and guaranteed response time for a monthly fee. If it's new, it's a milestone. If it's keeping something running, it's a retainer.
What happens if I want to change something mid-project?
Changes outside the defined scope of a milestone are quoted as a separate line item before we touch them. Nothing gets built until the change is agreed in writing. This protects both sides from scope drift and eliminates invoice surprises.
Can you just consult without taking on full development?
Yes. XR Consultancy is a standalone service available as hourly sessions or multi-session bundles. Architecture reviews, technology selection, second opinions on builds in progress, hands-on technical guidance. No development commitment required.
What types of XR projects do you take on?
VR, AR, and mixed reality projects across entertainment, research, training, defense, and cultural use cases. If it involves XR and needs to work reliably with real users, it's in our wheelhouse.
Do you build for specific headsets only?
No. We take an OpenXR-first approach and have shipped across Meta Quest, Pico, XREAL, and mobile AR (Android/iOS). We deliberately avoid locking clients into a single vendor ecosystem.
Do you work with international clients?
Absolutely. We've worked with clients in the US, Ghana, France, and across Europe. Most collaboration is async-friendly and we're comfortable across time zones.
