Book Discovery Week
About · Two founders · One studio

A small studio. Two operators. Built for SMBs that prefer working systems over working keynotes.

Hi-Ai is a two-founder studio split between Valencia and Berlin. One of us comes from a decade of automating SMB workflows. The other comes from cloud security and compliance. Most AI work needs both, and most agencies have neither.

We started Hi-Ai because the automation conversation in 2019 was already broken — full of demoware, light on operators. By 2026 the AI conversation is the same shape, just with bigger budgets attached. We are not interested in either pitch deck. We ship working systems for businesses that have to live with the result.

01The founders

Stefan Reichenbach

Stefan Reichenbach

Co-founder · Automation architecture & operator engagement

Valencia, ES

Ten years building workflow automations for small and medium businesses across Spain and Germany — from order management for logistics SMBs in Hamburg to client intake systems for legal firms in Valencia. Started Hi-Ai in 2019 to do the work properly: scoped, priced, exit-able. Every brief on this site reaches him directly.

  • Workflow design across sales, ops, support, and finance

Stefan Stoll

Co-founder · Cloud security, IAM & compliance

Berlin, DE

Cloud security and AI integration consultant. Came up through cyber-analytics and defence work at Fernao Magellan, then cloud security engagements at Paradox Networks and Axians IT-Service. Bachelor thesis on LLM-powered knowledge transfer at a leading German cybersecurity firm. The reason your compliance team will sign off on what we build.

  • Cloud security — Zero Trust, M365 + GCP hardening, identity and access
  • GDPR-compliant AI tooling and data residency design
  • Endpoint protection, email security, anti-phishing
  • German, English, Spanish (B1)

02Who does what

The studio splits along two lanes. Engagements involving customer data, regulated workflows, or anything touching identity / access run jointly.

Reichenbach lane

Discovery Week, workflow scoping, operator interviews, integration design, MVP build, change management. Anything that touches the daily working life of the team using the system.

Stoll lane

Cloud-security review, identity/access, GDPR + DPA scaffolding, secrets management, audit-trail design, vendor risk. Anything that touches what your auditor or DPO will ask about.
