01 — Solutions
A complete IT engine, assembled around your business.
Each capability is delivered as an integrated practice, not a siloed service — software, infrastructure, and security working from the same blueprint.
Practice
Cloud & Infrastructure
Resilient cloud environments across AWS, Azure, and Google Cloud, automated end-to-end.
Practice
Cybersecurity
Continuous detection, hardened identities, and audit-ready governance.
Practice
Automation
Workflows that remove toil.
02 — Who we are
A senior engineering partner, not a vendor.
GRASS HOLDING GmbH is an independent technology company focused on durable software systems and long-horizon IT partnerships. We work alongside operations, product, and security teams to ship reliable digital infrastructure.
- Engineering-led delivery
- Documentation-first
- Security by default
- Predictable timelines
03 — Core services
Eight focused practices, one accountable team.
Custom Software
Bespoke platforms built around your operational model.
Web Development
Performant, accessible web experiences at any scale.
IT Consulting
Strategy, architecture, and modernization roadmaps.
Cloud Solutions
Resilient cloud environments across AWS, Azure, GCP.
Cybersecurity
Hardened identities, monitored systems, audit-ready.
Business Automation
Workflows that remove toil and reduce error rates.
Data Management
Pipelines, warehouses, and governance you can trust.
Technical Support
Long-term operational ownership and SLAs.
04 — Software
Software that holds up under real production load.
From the first architecture sketch to year-five maintenance, we treat every system as a product that has to live, scale, and stay secure long after launch.
Discovery & architecture
Domain modeling, technical strategy, build-vs-buy.
Implementation
Typed, tested, observable code shipped continuously.
Quality engineering
Automated tests, performance budgets, accessibility.
Long-term ownership
Versioning, upgrades, on-call rotations.
services/payments/router.ts
export const router = createRouter({
routes: [
{ path: "/charges", handler: charges },
{ path: "/refunds", handler: refunds },
{ path: "/webhooks", handler: webhooks },
],
middleware: [authz, traceId, rateLimit],
telemetry: { service: "payments", tier: "core" },
});
await router.listen({ port: 8080 });05 — Cloud & Infrastructure
Cloud environments designed to be quiet on call.
We codify infrastructure, treat deployments as routine, and instrument every service so issues are detected before users feel them.
AWS / Azure / GCP
Multi-cloud delivery
Reference architectures across providers with portable workloads.
IaC + GitOps
Declarative platforms
Terraform and Kubernetes pipelines auditable line-by-line.
SRE practice
Operational maturity
SLOs, error budgets, and runbooks documented from day one.
06 — Cybersecurity
Security treated as an engineering discipline.
From identity and access to detection and response, we build security into the systems we ship rather than bolting it on afterwards.
Identity & access
Federated SSO, least-privilege roles, hardware-backed keys.
Application security
Threat modeling, secure SDLC, dependency hygiene.
Cloud posture
Continuous configuration review and drift detection.
Monitoring & response
Telemetry pipelines, alert tuning, incident playbooks.
Compliance
ISO 27001, SOC 2, and GDPR-aligned controls.
07 — Business automation
Reclaim hours, weeks, and quarters of operational time.
We map repetitive workflows, replace fragile spreadsheets with reliable services, and integrate the tools your teams already depend on.
Process discovery
Quantified mapping of manual workflows.
Integration layer
APIs, queues, and connectors that talk to anything.
Internal tools
Custom dashboards for operations and finance.
AI assistance
LLM-powered helpers grounded in your own data.

Domains we work across.
Our engineers carry experience across regulated, data-heavy, and high-availability environments.
Financial services
Industrial & manufacturing
Healthcare & life sciences
Logistics & supply chain
Energy & utilities
Professional services
Retail & commerce
Public sector
