For CTOs, CIOs & Engineering Leaders

Targeted Mandate — 4 to 12 weeks

When the project must ship
and your team can't get there alone.

You walk away with the project shipped, the work in your team's hands, and a clean exit at the end of the mandate — no retainer that lingers.

The same practitioners who would author your architecture are available to operationalize it. Mandates from 4 to 12 weeks. Senior-only. Scope locked at commissioning.

Targeted Mandates. Construction frameworks. Diagnostic services. One standard. We build systems we won't diagnose. We diagnose systems we didn't build.

Four terms that scope the engagement.

Duration.

Four to twelve weeks, scoped to the bottleneck.

Practitioners.

Senior-only. No analyst backbench, no body shop.

Scope.

Locked at commissioning. No retainer expansion mid-mandate.

Exit.

The engagement closes when the bottleneck ships — not when the calendar runs out.

Five decisions you walk away ready to defend.

01

Rewrite vs. Refactor — the committed-capital decision

The canonical growth-stage architectural question. Five diagnostic tests decide it unambiguously. A five-day Risk Scan produces the answer before the board meeting forces the commitment.

02

Post-Incident — the first 90 days

After a serious production incident, six decisions must be made within 90 days. Delay compounds. An independent review establishes whether the incident was isolated or structural — and what to change before the next one.

Diagnostic Services →
03

LLM Platform — from pilot to production

Most LLM pilots succeed technically and fail operationally. The failure is almost always at the system boundary, not at the model level. MindCore-framed reviews diagnose the boundary before the rollout exposes it.

04

Scale Transition — 200 to 2,000 engineers

Four architectural and organizational transitions break most companies between Series C and post-IPO. Each is predictable in advance and invisible in quarterly reports. A diagnostic engagement surfaces them before they become incidents.

05

Pre-Commit Review — before the platform decision

Before the migration, the rewrite, the platform build. An independent review that answers: is the plan architecturally sound, or is the team solving for the wrong constraint?

Two ways to commission a system that holds under load.

What earlier mandates kept running in production.

Four things you cannot commission from a Big 4, an MBB, or a generalist firm.

A finding or a built system — not a pitch.

Eligere does not sell implementation work at organizations it has diagnosed, and does not pivot a Diagnostic into a multi-quarter retainer. The recommendation is never steered by the services we would then sell. What you get is a finding or a built system — not a pitch.

The same engineer from Brief to delivery.

The engineer who wrote the Brief is the engineer doing the work — whether the engagement is a Diagnostic review or a Construction mandate. Twenty-five years of production systems experience shows up in every session, not once in the kickoff, then replaced by juniors.

An engagement scoped to the decision, not the retainer.

Quick-Read in three days, Risk Scan in a week, Protocol in fifteen, when the question is review. IronCore and MindCore mandates scoped to the system, when the question is build. Engagement length is matched to the decision the work must inform — not to a billing structure.

Judgment you can verify before you commission.

The Briefs archive is the record of what we believe and how we reason. You can read the doctrine before commissioning the engagement — and know exactly whose judgment you are commissioning.
