Senior engineers. A long-term commitment to your software.
We build and maintain operational software for businesses and consultancy partners in the UK, Switzerland, and beyond. Our team combines hands-on development with technical leadership, from the first engagement through ongoing improvements and support.

E2 Innovativ Informatik GmbH is registered in Zug, Switzerland, and signs contracts and invoices clients and consultancy partners. The founders provide operational oversight and management from South Africa.
E2 subcontracts development to UME, the South African engineering business founded by Martin and Natalie Ernst, who are also part owners of E2. The delivery team comprises three senior developers. Allocation and start dates are agreed for each engagement.
Our founders and team built and supported the Xexec rewards platform from 2008 to 2025. This is the founders' delivery experience, rather than E2's corporate history.
Delivery Principles
Clarity
We agree scope, assumptions, responsibilities, and acceptance criteria early, then flag changes to timing and budget as they emerge.
Reliability
We design and build systems to support real operations, with maintainability and day-to-day dependability treated as core delivery requirements.
Accountability
A named E2 lead, weekly progress updates, and shared team knowledge keep delivery and ongoing support connected.
The People Behind E2
E2 is run by Martin Ernst and Natalie Ernst from South Africa through a Swiss-registered company based in Zug.
