How it all began

Erfahrungen bei den BIG4
2009 timeline

Experience with the BIG4

At the beginning there was the experience in a BIG4 company.
Recurring manual activities in the audit of SAP quickly revealed the necessity of an automated solution that "only" has to read out data and relate it to audit-specific data. Unfortunately one was alone with such innovative thoughts in a BIG4 society on far corridor.

Research: Virtual Accounting Worlds

Universities as a suitable place for innovations.
In 2010, it was possible to win a research project funded by the BMBF for 3 years, because research also requires resources and means. The Financial Process Mining Algorithm was developed at the University of Hamburg (Prof. Dr. Markus Nüttgens) and is still in use today.

Foundation: zapliance GmbH

Bringing research results to market maturity.
After the project, the question arose as to whether it should remain purely academic, or whether the findings should be transferred to a higher degree of maturity. It was agreed that the digitization of the revision was relevant and interesting, and had potential.

Collective Audit Intelligence (CAI)

Conclusions based on past audits.
From 2016, the CAI innovation project was supported by a grant from the Hamburgische Investitions- und Förderbank (IFB) as part of the PROFI innovation support programme (Programme for Innovation). The goal is a self-learning system that combines the knowledge of past audits into an artificial intelligence.

A glimpse into the future

The future of auditing will be decided in the tension field between automated analyses and the professional auditors interpreting them on the basis of their experience and professional knowledge. In the final analysis, the writing on the wall for the auditing profession reads: "Digitize or Die".

We are ready to go the way with you!
