About Mechanical Advantage

Mechanical Advantage builds Fulcrum, a workforce of AI agents you hire to run your business. You ask, in plain English, and they do the actual work, around the clock, on a computer you own.

The name is the idea. A lever and a fulcrum let one person move a load no person could lift alone. That is what we want for the owner-operator: the leverage of a whole team, in the hands of one.

Why Fulcrum Exists

Most small businesses are run by one person who is the bottleneck for everything: the invoicing, the follow-ups, the weekly email, the numbers, the hundred small jobs that pile up after hours. Hiring help rarely pencils out. And the AI everyone keeps recommending feels like it was built for big companies and tech people, not for them.

It doesn’t have to be. The same kind of AI workforce a large company can stand up is now within reach of a single owner, if something sits above the agents and keeps the work coherent. That something is Fulcrum. You hand off one annoying job, then another, and over time the system that runs your business builds itself.

Our Principles

  • A workforce, not a chatbot. Fulcrum is a team of specialized agents that do real work, not a single assistant you have to babysit. Humans do what only humans should; agents run the rest.
  • Runs on your own hardware. No SaaS dashboard, no cloud execution. Fulcrum runs on a computer you own, ideally a small, always-on mini PC. Your customer list, your numbers, and your decisions stay on your machine, under your roof.
  • Built for the non-technical owner. No code, no setup wizards, no jargon. You ask in plain English. If you’d like a hand getting started, we’ll set it up with you.
  • You’re always in control of cost. A simple monthly price, plus the cost of the AI that does your work, shown to you in plain dollars, in real time, with no surprises.

Our Team

We practice what we sell. Mechanical Advantage is a one-person Human Workforce and a small AI Workforce running on machines we own, each a quiet, always-on mini PC doing real work.

David Weiss

Founder

David founded Mechanical Advantage to give one person the leverage of a whole team. He has run businesses of nearly every size, from his family's manufacturing companies as a teenager, to engineering and product roles at Microsoft, to CEO, CTO, and VP of Product seats across startups and small and mid-size companies. Fulcrum is the tool he wished he'd had as a solo operator.
