Product engineering for difficult systems that need a clear path to delivery.

Turn the stuck system into a clear next step

Share the system, business goal, constraints, budget range, and timeline. You will receive a fit decision and the next useful step.

Response
Usually within one business day.

Good fit

  • You need a working product slice, internal tool, AI workflow, or technical rescue.
  • There is a clear owner who can answer product and business questions.
  • You can share enough system context to map constraints and trade-offs honestly.
  • You value direct senior engineering ownership over a large handoff process.

Probably not a fit

  • You only need commodity implementation with no product judgment.
  • The project depends on unapproved customer data or secret material.
  • The ask requires public claims that cannot be verified.
  • The budget cannot support the Diagnostic entry point.

What to include

A useful brief makes the goal, constraints, budget, and timing clear enough to decide whether there is a fit.

Budget range

  • Diagnostic at USD 350
  • Build Sprint from USD 2,500
  • Product Partnership custom quote
  • Not sure yet

Timing

  • Diagnostic in 3 business days
  • Sprint in 1-3 weeks
  • Partnership roadmap
  • Exploring timing

Choose the level of commitment that matches the decision in front of you. Pricing follows scope and deliverables, not time sheets.

  • Fixed fee: USD 350

    3 business days

    AI & Product Diagnostic

    USD 350 fixed. In 3 business days, receive a prioritized technical and product implementation path.

    Best for
    Founders and operators who need clarity before committing to a build.

    Included

    • Discovery, Analysis, and Delivery across 3 business days.
    • A decision package with architecture, roadmap, recommended stack, implementation phases, budget, and timeline.
    • Use it to decide whether to build, pause, or change direction before a larger commitment.

    Best entry point when the problem is valuable but the path is still unclear.

  • Starting at: USD 2,500

    1-3 weeks

    Build Sprint

    Starting at USD 2,500, generally 1-3 weeks to deliver a usable slice with a defined scope.

    Best for
    Teams ready to ship a vertical slice, internal workflow, or AI-enabled product path.

    Included

    • A focused scope tied to one usable product or workflow slice.
    • Product, architecture, and implementation decisions stay connected through delivery.
    • Start after a Diagnostic or when the target and constraints are already clear.

    Designed for momentum when the product decision and constraints are understood.

  • Custom quote

    Product Partnership

    Custom quote for systems that need ongoing product and engineering decisions.

    Best for
    Ongoing product and engineering ownership when the system needs sustained decisions.

    Included

    • Custom roadmap, cadence, and delivery shape.
    • Useful for operations software, AI systems, and platforms that need ongoing decisions.
    • Quoted from scope, risk, and expected ownership.

    Best when GreyX needs to stay close to product decisions beyond one sprint.
