How we support German small and medium-sized enterprises in overcoming technological challenges.
Callumi
The Technology Challenge
Municipalities manage their street lighting across separate, siloed tools – citizen reports, on-site repairs and billing drift apart.
Our High-End Engineering Solution
A multi-tenant, offline-capable field-service platform for street lighting: an interactive map and a seamless workflow from report to invoice.
Measurable B2B Result
A closed loop from citizen report to billing – offline-first in the field, web and iOS from a single codebase, with zero map licensing costs.
Meine Akte 2.0
The Technology Challenge
Law firms manage case files, deadlines and receivables in outdated, fragmented software – with error-prone, manual legal calculations.
Our High-End Engineering Solution
Development of a multi-tenant legal practice platform with a legally accurate receivables ledger, native e-invoicing and server-side AI.
Measurable B2B Result
A receivables ledger at market-leader level, proactive limitation-period warnings and end-to-end tenant isolation via Row-Level Security.
Technology Without Compromise
We rely on professional software engineering principles. For every project, we choose the right technology—instead of forcing every task into the same mold. That means: no off-the-shelf WordPress solutions, no plugins that will stop working tomorrow. We build durable core systems that fit your business—not the other way around.
