Early access to Xypher Engine, with a direct channel to shape what the platform becomes.
Early access to Xypher Engine while it is actively being built. This means using the platform before it reaches general availability, across the engineering lifecycle phases that are available at the time you join.
A direct feedback channel to the Stellanex engineering team. Not a support ticket queue: a structured feedback system where what you report informs what gets built next and how the engineering workflow is structured.
Access to changelogs and release notes covering every change made to the platform. You will know what changed, why, and how to evaluate whether it addresses what you reported.
The founding cohort position. Design Partners who join during early access are the engineers the platform is built around. That influence does not transfer to later cohorts.
Free during early access. No pricing applies while the platform is pre-release.
Use the platform before general availability, on a real engineering project.
Structured feedback that informs what gets built next, not a support queue.
Every change, every release, with context on what changed and why.
The engineers who shape the platform in its earliest phase. This position does not transfer.
No pricing applies while the platform is pre-release.
Active use on a real engineering project. The feedback that matters for a development platform comes from engineers who encounter its limitations while trying to accomplish actual engineering work, not from evaluators running test scenarios. If your goal is evaluation before commitment, the Design Partner program is not the right fit.
Structured, honest feedback through the feedback system. The platform is going to have gaps, edge cases that do not work as expected, and workflows that need to be redesigned. Identifying and reporting those accurately is the most useful thing a Design Partner can do.
Responsiveness when the Stellanex team needs clarification. Bug reports and feature requests sometimes require follow-up to reproduce or understand the engineering context. Being available for a brief back-and-forth is part of the program.
Nothing else. This is not a beta testing agreement, a co-development contract, or a commitment to purchase. It is a working engineering relationship.
Nothing else.
Engineers and teams who build intelligent machines across the full development lifecycle: design, simulation, programming, hardware integration, and deployment. The platform is built for engineers who encounter the fragmentation of that lifecycle directly, not for teams working within a single discipline.
The Design Partner program is specifically suited for:
Engineers who build the whole machine themselves. Individual engineers or small teams spanning multiple disciplines who need the engineering workflow to be continuous across all of them.
Organizations running real development programs. Teams with active projects where the engineering infrastructure gap is a real constraint, not a hypothetical.
Engineers who can commit to honest, structured feedback. The program is not useful to either party if the engineering relationship is surface-level.
The program is not suited for enterprise procurement evaluation, academic coursework, or individual curiosity without an active engineering project.
Free during early access. No pricing applies while the platform is pre-release. Pricing for Pro and Team tiers will be announced when the platform reaches general availability. Design Partners are not automatically committed to any paid tier.
No service level agreement. Xypher Engine is pre-release software. It is actively being built. Capabilities will change. Some things will break. The platform is not suitable for production deployment during early access.
Engineering data is not preserved across major changes. Work done in the platform during early access is for evaluation and feedback purposes. Do not use the early access environment for engineering work where data loss would be consequential.
Full program terms are in the Terms of Use.
Applications are reviewed by the Stellanex engineering team. Acceptance is based on fit with the program's engineering requirements: active project, full-lifecycle development work, capacity to provide structured feedback.
