Custom software
Web and business applications, APIs, integrations and internal tools built around your actual processes — with the rigour of bespoke software.
Engineering & sovereign cloud
Engineering & CloudYour applications deserve engineering built to last.
We design, develop and operate your custom software, SaaS platforms and cloud infrastructure — with a senior engineering team involved from design through to operations.
01
What we do
Four areas, one technical team — from initial scoping to production on-call.
Cloud & hosting
Kubernetes clusters, CI/CD and monitoring operated with Infomaniak in Switzerland. Data sovereignty, resilience and on-call support.
Technical advisory
Architecture audits, stack selection, MVP scoping and CTO reinforcement for your product and IT teams.
Data & automation
Data pipelines, ETL, reporting and AI integration into your existing tools — without a full rebuild.
02
Sovereign infrastructure in Switzerland
Your workloads run on Infomaniak infrastructure — an independent Swiss cloud operator. Rehzzo designs the architecture and handles operations.
Infrastructure operator
Infomaniak provides datacenters, networking and IaaS/PaaS services in Switzerland. Rehzzo deploys and operates your environments on this foundation.
- Datacenters 100% located in Switzerland
- ISO and Swiss Hosting certified operator
- B Corp company and ICANN-accredited registrar
- Ethical cloud, independent of US hyperscalers
03
Our approach
No empty sprints or surprise rebuilds. Three phases that reflect how a well-run project actually works.
Scope & architect
Audit, functional scoping, technical choices and roadmap — before writing the first line of code.
Design & deliver
Iterative development, code reviews, testing and progressive deployments through to production.
Operate & evolve
Monitoring, maintenance, functional evolution and continuous optimisation of your stack.
Experience
10+ years
Of software engineering and hosting for demanding business projects.
04
What changes with Rehzzo
Three concrete commitments — from initial scoping to overnight on-call.
Digital sovereignty
Data hosted in Switzerland with Infomaniak, outside the scope of the CLOUD Act.
Technical resilience
Architectures designed to absorb failures and traffic spikes without lasting interruption.
Proximity & expertise
A senior engineering team that stays after go-live — not anonymous support.
05
In production
Three projects, three different sectors — one level of technical rigour.
Hyspose, Sejourna and Aureus illustrate how we work: a technical team that designs, builds and operates the product in production — not just the initial delivery.
