Complement, Don’t Replace: How Kidbrooke Helps German Insurers Launch for 2027

How German life insurers can build a credible, digital-native pension projection capability for the Altersvorsorgedepot, without replacing the systems already keeping the business running.

This is the third and final post in our series on Germany’s pension reform and what it means for life insurers. In the first post, we set out why the Altersvorsorgedepot creates both a competitive threat and a genuine opportunity for incumbents. In the second, we went into why the challenge is architectural, not just a communications problem, and what a single, channel-consistent analytics engine actually needs to do. This article answers the question we hear most often from product and technology leaders: How do we get there without breaking what is already working?

It is a legitimate concern. Policy administration systems, actuarial engines, and regulatory reporting tools represent years of investment and are deeply embedded in operational processes. A platform change that touches them carries delivery risk, regulatory risk, and the real possibility of disrupting live business while trying to improve future business.

The answer, but also the reason many insurers get stuck when they look at the vendor landscape, is that the framing is wrong. One point to note is that this is not a replacement programme but rather a layer, and Kidbrooke sits above existing systems, not instead of them.

An API-first layer above existing infrastructure

The KidbrookeONE platform integrates via API into existing policy admin systems, execution layers, and data sources, consuming what is there, rather than replacing it. The stochastic simulation engine that powers pension projections, gap analysis, and scenario-based illustrations is exposed as a set of API endpoints that any channel can call. Nothing gets removed, or needs to be rebuilt. The existing infrastructure continues to run the business, and KidbrookeONE adds the analytical layer that the business is currently missing.

This architecture also directly solves the channel consistency problem described in our previous post. Because all channels call the same API, they get the same numbers. The customer portal, the adviser tool, and the regulatory disclosure document all draw from the same engine, the same assumptions, and the same scenario set. When the Altersvorsorgedepot regulatory parameters evolve, as they will in the months after launch, there is one place to update them, and every channel inherits the change without a patching exercise across multiple systems.

Modular adoption, not a big-bang programme

KidbrookeONE comprises of twelve independently deployable modules; covering onboarding and KYC, advice and forecasting, portfolio analytics, product configuration, payments, reconciliation, and more. The critical point for a German insurer targeting January 2027 is that they do not need all twelve modules but one entry point, scoped tightly to the problem at hand.

The most natural starting point is the Forecasting and Advice capability: the stochastic projection engine, the gap analysis functionality, and the customer-facing presentation layer. This can be integrated into an existing portal or customer journey without touching the underlying policy admin or execution infrastructure. For most German insurers, the specific capability that is missing is the ability to show a customer what their Leibrente, a guaranteed lifetime income, will actually deliver in monthly income terms, across a range of market scenarios, and how that compares to simply drawing down their savings. That is the comparison that makes the insurance proposition tangible and sellable. It spans both the accumulation and payout phases, runs thousands of economic scenarios, and returns probability-based percentile outputs that meet BaFin’s Kundennutzen standard. It is what the Altersvorsorgedepot environment demands, and it is the module that makes the insurer’s proposition visibly competitive with the neobroker experience.

Additional modules; product configuration, admin portal, reconciliation and reporting, can be added incrementally as the value compounds and requirements grow. This is the difference between a programme that can be scoped, priced, and delivered within a realistic timeframe, and one that requires multi-year transformation before any customer sees a result. No rip-and-replace, or big-bang programme, just start with one capability, prove it and then expand from there.

What delivery actually looks like

The most relevant proof point for German insurers is Skandia, the Swedish life insurer and one of the Nordics’ largest pension providers. Skandia built a fully digital pension advisory journey on KidbrookeONE in four months. That was going from concept to a live platform within one quarter. The journey covered risk profiling, probabilistic retirement projections, goal feasibility, and an adviser proposal tool, all powered by the same analytics engine and drawing consistent numbers across every channel.

That timeline is not held out as a guarantee. Every implementation has its own complexity, integration points, and regulatory context. But it establishes what is achievable when the analytics engine is already built, the APIs are already documented, and the integration pattern is already understood. For a German insurer with a January 2027 target, a scoped proof of concept; one product, one customer journey, projection and gap analysis capability integrated into an existing portal, is a realistic deliverable within that window, provided the decision is made in the near term.

The competitive argument for moving now

The case for acting now is not only about compliance. Neobrokers including Trade Republic and Scalable Capital are already preparing day-one launches, with digital-native experiences that are interactive, visual, and probability-based. Those experiences will set the benchmark customers carry into every subsequent conversation with an insurer’s adviser or portal. An insurer that launches in January 2027 with a compliant but static proposition will be competing against that benchmark from day one.

Life insurers have genuine advantages that challengers will take years to replicate: customer relationships built over decades, distribution networks, actuarial depth, and the regulatory credibility that comes with a long track record. The gap that needs closing is the digital experience layer, and specifically the ability to show a customer, clearly and interactively, what their pension is likely to deliver, and what they can do to improve the outcome. That is the gap the Altersvorsorgedepot exposes, and KidbrookeONE is built to close.

The window to do this well, to build something insurers are genuinely proud of, rather than something shipped under pressure, is open now. The German life insurers who take the first step in 2026 will launch with confidence.
