Your Site Is Going All-Electric.
The Only Question Is:
With a Plan – or With Costly Lessons?
Frank Hummel built a company with 100+ employees and sold it to STRABAG/Züblin. Today he supports leadership teams with energy transformation, site optimization and strategic decisions – through sparring at eye level, not traditional consulting.
How We Work Together.
Three steps – from the first conversation to orchestrated implementation. You decide at every step whether and how to proceed.
Initial Consultation
30 min – Phone or Teams
We clarify where you stand, what you’re planning, and whether we’re a good fit. No obligation, no sales pressure – just an open conversation at eye level.

Entrepreneurship Since 1993
I founded HUMMEL Systemhaus and scaled it to over 100 employees. Expanded in 2016 to a full-service provider with ICT and REVOLUTION E, strategically sold to a leading European construction group in 2020. Three more years as CEO and division head in the corporation, exit end of 2023. HSG is my entrepreneurial platform – the place where experience, infrastructure and execution power come together.
Today I support leadership teams and decision-makers on questions of transformation, future-readiness and entrepreneurial development – not from theory, but because I’ve lived through these situations myself.
