About Stacked Drive

Stacked Drive is the playbook of one solopreneur shipping real production sites. No agency case studies, no theory — every tool reviewed, every workflow documented, every tradeoff named comes from sites that are live, paying customers, and pulling their weight.

The Playbook bundles ~25 tool reviews and 6 workflow recipes, drawn from 17+ production sites spanning content, services, and SaaS. If you've drowned in tutorials, comparison tables, and "best-of" lists that pretend everything is great, this is the antidote: opinionated, accountable, battle-tested.

Who I am

I'm Denny Guhlmann, an indie operator based in Chemnitz, Germany. I build, write, and ship — and I document what works (and what doesn't) so other solopreneurs don't have to repeat the same expensive lessons.
