Expansion engine

Legacy systems replaced —
at a fraction
of the cost and time.

Your legacy systems get analyzed, documented, and modernized with AI-assisted methods — while operations of the old systems continue uninterrupted during migration. One partner, one plan, no double team. AI Operating System path when legacy systems block AI adoption.

02 / Deliverables

What rebuilds.

A modernized stack is the artefact. A live workflow on top of it is the proof.

03 / Process

Four phases.
The stack ships in slices, not at the end.

No 9-month replatform that lands in one cutover. Each slice runs in shadow against the old stack first.

Phase 01 · M1Diagnose

Workflow + stack audit. Methodology applied. Slice plan locked.

Phase 02 · M2–M4Build slice 01

Data + workflow planes for one workflow. Shadow mode against legacy.

Phase 03 · M4–M6Production cutover

Switch traffic. Legacy retires. Cost-out starts compounding.

Phase 04 · M6–M9Compound

Slices 02–04 land on the same plane. Each is faster + cheaper than the last.

03.5 / How this connects

Modernization is the expansion engine of the AI Operating System path.

Most Modernization engagements surface during Plan 2 or Plan 3 of the unified path — when legacy systems block AI adoption. It runs in parallel with the build, or as a follow-on after the OS is live.

During Plan 2Integration blocks the workflow.Audit triggered · Stabilization sprint to unblock
During Plan 3Legacy systems block the OS.Migration runs in parallel · slice-by-slice cutover
After Plan 3OS live, legacy remains.Follow-on engagement · the AI-native stack catches up

04 / Investment

Two entry points. One depth tier when you commit.

Most engagements start with the Audit — a clear recommendation, migration plan, and cost frame in 2–3 weeks. Stabilization keeps the legacy running while the AI-native rebuild begins.

05 / Why us

Why this isn't a replatform.

Replatforms fail because they ship at the end. This ships every slice.

Shadow-first, always.

Every slice runs in shadow against the legacy system before traffic switches. Cutovers are anti-climactic on purpose.

Model-agnostic by construction.

The data + workflow planes are written so swapping models or providers is a config change, not a project.

Supervisor-ready, not supervisor-friendly.

BaFin, FINMA, sectoral regulators — your filing pack is a deliverable, not an afterthought. Supervisory language built in.

You can stop and own it.

If after M06 you don't want slices 02–04, you walk with a working stack and a live workflow. No vendor handcuffs.

06 / FAQ

Questions CTOs ask before signing.

How do you avoid the classic replatform death spiral?

No 9-month replatform. The slice plan means your production cutover happens in month 06 — on a narrow workflow — and the rest compounds on a stack that's already live.

What if our existing engineering team needs to lead it?

Then they should. Our pod can run alongside as senior reviewers and pair-ship instead of leading. Pricing flexes downward; KPIs and guarantees don't.

Are you tied to a specific cloud or model provider?

No. Proven across AWS, Azure, GCP, Hetzner, OVH, on-prem, and air-gapped environments. The data + workflow planes are built so provider swaps are a configuration change, not a project.

Can we use this as a managed-service exit ramp?

Yes — that's a common pattern. Several engagements have replaced 7-figure annual SaaS / managed-service contracts with the new stack. The cost-out memo accounts for it.

What about audit, security, pen-test?

The governance plane is the deliverable here. You get a bundled DPIA, model registry, audit log spec, pen-test scope, and supervisory filing kit. Your auditors get a single binder.

Next step

Start with the Audit.
A clear recommendation in 2–3 weeks.

If you're already in Plan 2 or Plan 3, the Audit slot is reserved. If you're approaching Modernization standalone, the Diagnostic tells you whether it's the right next move.
