The software your business actually runs on.

We build B2B CRM and operations software for companies that have outgrown generic tools. Engineered in Berlin, for Germany and beyond.

Four systems in production. None of them off the shelf.

Every screen behind this line is something we built and still run.

Generic software makes your team work around it.

Every workaround has a running cost: a spreadsheet somebody maintains by hand, a message thread standing in for a process, a number nobody quite trusts. Together they cost far more than the licence ever did.

We start by learning how your operation actually runs, then build the system that runs it. Your rules, your data, exportable in full whenever you ask for it.

  1. 01

    Discovery

    We map how the work moves today, including the parts nobody ever wrote down.

  2. 02

    Build

    Working software early, then in increments you can open and check for yourself.

  3. 03

    Migration

    Your data out of the old system, a period of parallel running, then a cutover that does not stop the business.

  4. 04

    Operate

    We stay on afterwards. The system keeps changing because your operation keeps changing.

Client buildLive

A custom CRM built to replace the platform a company depended on

Their entire book of business sat in a third-party system that kept clients on one page and their payments on another, and offered no way to get their own data back out. We are rebuilding it as one platform they own outright.

  • Clients and payments in a single list, ordered by what needs attention today rather than alphabetically
  • A retainer ledger and commission engine that accrues only on payments that actually cleared, and reverses when one is returned
  • Enrollment where the signature itself creates the record, the payment schedule and the attribution, with no back-office hand-off
  • Row-level access enforced in the data model, an audit trail that cannot be edited, and full data export on demand

What we build

B2B CRM and operations software

A system shaped around how your business already works: records, ledgers, approvals, roles, reporting. Built to be owned rather than rented, with your data exportable in full at any time.

Platform and web engineering

Web applications, customer portals, internal tools, and the integrations that connect them to what you already run. TypeScript and Next.js, deployed on infrastructure you control.

Tell us how your operation actually runs.

A first conversation is a conversation, not a pitch. If a custom build is the wrong answer for you, we will say so.
