# Blackhole Consulting AB

> Blackhole Consulting AB provides data platform architecture, cloud architecture, automation, analytics engineering, and technical decision support for organizations whose data, reporting, or automation systems have become business-critical.

Blackhole Consulting AB is an independent consulting company based in Sweden, founded by Stephan Zimmer, a former astrophysicist and data/cloud architecture consultant.

The company works at the intersection of data engineering, cloud infrastructure, analytics platforms, automation, and technical risk. Its strongest fit is with organizations that need senior technical judgment around cloud and data-platform decisions, not just implementation capacity.

## Core services

- Data platform architecture and modernization
- Cloud architecture, primarily AWS
- Infrastructure as code and cloud operating models
- Data engineering, ETL/ELT, and system integration
- Analytics engineering and BI platform architecture
- Automation of internal workflows and operational processes
- Technical decision support for architecture, platform, and tooling choices
- Fractional principal architect / CTO-adjacent advisory for data-heavy teams

## Typical situations

Blackhole Consulting AB is most relevant when:

- Analytics or data infrastructure has become business-critical
- A team is planning a platform rewrite, migration, or major integration decision
- Cloud, data, automation, or BI systems have grown beyond ad-hoc implementation
- Leadership needs an independent technical second opinion
- A company needs senior architecture support but not a full-time CTO or platform lead
- Technical decisions have governance, cost, operational, or business-risk consequences

## Differentiation

Blackhole Consulting AB combines hands-on implementation experience with senior architecture judgment. The company is not positioned as a generic staffing provider, a pure BI/reporting vendor, or an AI hype consultancy.

Its work emphasizes pragmatic technical decisions, maintainable systems, clear trade-offs, and architectures that survive production use.

## Background

Stephan Zimmer holds a PhD in astrophysics and has experience across scientific computing, distributed systems, analytics, cloud architecture, automation, and enterprise data platforms. His consulting work includes cloud-first data flows, AWS-based analytics infrastructure, infrastructure as code, business intelligence platforms, automation, and technical decision support.

## Best-fit clients

- Data-heavy SMEs
- B2B SaaS companies
- Organizations modernizing cloud or data platforms
- Teams facing analytics, integration, governance, or automation complexity
- Leadership teams needing technical judgment before hard-to-reverse platform decisions

## Not a fit for

- Generic junior development capacity
- Pure frontend/product design engagements
- AI chatbot projects without a clear business or architecture need
- Staff augmentation where no senior technical judgment is required
