Remote Native  /  AI-Native Modernization
Expansion engine

Modernize only where
the current stack
is taxing the business.

Not because a system is old. Where staying costs you: slower change, expensive integrations, manual work, key-person or supplier dependency, unreliable data, or automation that cannot get in. We analyze, document and modernize with AI-assisted methods while the old systems keep running through the 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.

04 / How this connects

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

Most Modernization engagements surface during Production Proof or Scale 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.

05 / 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.

Audit + roadmap

€15-25k
Fixed · 2-3 weeks
  • AI-assisted code archaeology of the existing stack.
  • Documentation generated from the running code, not reconstructed by hand from memory.
  • Architecture review · risk mapping · key-person dependencies.
  • Clear recommendation: migrate / stabilize / leave-be.
  • Cost frame + slice plan for the full migration.
Audit fully credited toward Stabilization or Migration engagements within 90 days.
Entry · Stabilization & Ops Takeover

Run the legacy. Build the new.

€ retainer
Monthly · scoped per engagement
  • Legacy support is covered while the replacement gets built in parallel.
  • Stabilization sprint · bug triage · documentation backfill.
  • SLA-backed operations · senior ownership plus specialist capacity assembled for the mandate.
  • Migration plan executed in parallel, your team stays focused.
  • Counts toward continued Scale engagement (€5k credit per month).
Single partner, single plan, the differentiator vs. classic system integrators.
Depth · AI-native rebuild

Stack + 3-4 workflows

from €150k
Scoped after the Audit · 4-9 months · slices billed monthly
  • Stack — the data layer, services, integrations, and ops plane the legacy runs on. Replaced once, underneath everything.
  • 3-4 workflows — the load-bearing operational workflows rebuilt slice-by-slice.
  • AI-native — each workflow rebuilt as a Level 03 AI operator, not a Level 01 copilot.
  • Slice cutover — production by month 06; legacy retires as slices land.
  • Capacity — Engineering, architecture and domain specialists assembled for the mandate. CFO-signable cost-out memo.
Stop any month: stack is yours, instrumented, operating. No exit fee.
06 / 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.

07 / 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 specialists 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: the new stack replaces an annual SaaS or managed-service contract. 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 Production Proof or Scale, the Audit slot is reserved. If you're approaching Modernization standalone, the Diagnostic tells you whether it's the right next move.
