I'm an entrepreneur and industrialist. I invent tools, and I build the companies and the factories that make them.
I've started companies in power tools, material handling, consumer products and AI. We never raised venture capital. Each company grew on its own sales into a profitable business, and together they have brought in hundreds of millions of dollars over the past decade and sold millions of units.
We build what we design in our own factories in China and Vietnam, which employ hundreds of people directly, and we sell it all over the world.
Companies
Nemo Power Tools
Nemo makes cordless power tools that work underwater. They were the first of their kind, and divers, marine crews and pool builders use them all over the world. Popular Mechanics once tested the drill and the grinder in a bathtub.
GRABO
The idea for GRABO came to me on a climbing trip. I wanted something that could grab onto a rough rock wall. It turned into a handheld vacuum lifter with its own battery-powered pump. Unlike a suction cup, it holds on to textured stone, wood and drywall, not just glass.
Today GRABO is a $100 million brand with 150 employees. We sell it around the world under the GRABO name, and we license it to some of the world's biggest power tool brands and build it for them.
VACDRILL
A cordless drill that holds itself to the wall. It grips concrete, brick, stone and glass by vacuum, then drives a rotary hammer to the same depth every time, perfectly straight, with no one holding it.
Showing it at a trade show.
Other inventions
Lifewand is my invention for clearing the airway of someone who is choking. Anyone can use it, and it saves lives all over the world.
PaPro is a life-saving powered respirator that enriches the air with oxygen. I designed and manufactured it during COVID, and we sold and donated it by the container to several countries in Central America.
D-Dart is a one-handed automatic dart blaster. It was a best seller at Target two years in a row.
GizmoMaker
Israel's leading physical product development firm. I founded it while I was still a student at the Technion. It runs the GizmoMaker Inventors Un-Conference, where hundreds of inventors, makers and investors meet to show prototypes and trade ideas, and it is a hub for innovators.
Other companies
- Mecbit, a leading innovator in 3D printing software and a hub for prototypes. It was my first exit, acquired in 2013.
- AlphaBell, a research lab working on AI that improves AI.

Factories
Engineering, assembly, testing and shipping all happen under one roof, so the people who design a product work a few steps from the people who build it.




Team
None of this happens without the team: engineers, assemblers, testers, buyers, and the people in logistics, sales and support.
USA
Our American company is in Las Vegas. The team there handles sales, marketing, customer support and warranty, runs the warehouse, and gives products a second quality check after they arrive from the factory.
Some things I've learned
- Start with a market small enough to own.
- A product a few thousand professionals can't work without is worth more than one that millions think is nice. Win there first, then expand.
- Look for the problems an industry has stopped noticing.
- Old industries are full of them. They stay unsolved because they look boring, not because they are hard.
- The invention is the easy part.
- What competitors can't copy is the stack behind it: the factory, the suppliers, the dealers, the patents and the people. Each one gets built to solve a problem the last one created.
- Early adopters are not the market.
- They forgive rough edges. Everyone after them wants a complete product, a dealer nearby and spare parts in stock. Most hardware companies die in the gap between the two.
- Distribution is half the product.
- A great product people can't find is a hobby.
- Make it yourself.
- Owning the factory is slow to start and fast forever after. You learn what things really cost and where they fail, and you can change a product in a week instead of a quarter.
- Own the outcome.
- A late container or a bad batch is my fault until I've fixed whatever let it happen. Blaming a supplier gives away the only lever I have.
- Explain the why, then let people decide.
- A team that understands the goal makes better calls on the floor than I can make from an office.
- Grow on what you earn.
- A profitable company sets its own pace. Nobody else gets a vote on how long you have.
- A patent buys time, not safety.
- Use the head start to get far enough ahead that copying you isn't worth it.
Now
Lately I run more and more of the companies, and of my own life, through AI agents. They keep the books, file patents, chase shipments, deal with vendors and answer customers, and they write most of the software we use internally. I talked about it in Running my entire life with 200B tokens.
SoMa ProtoLab
ProtoLab is a four-floor loft building in SoMa that I bought so my friends and I would have a place in San Francisco to meet and work. We run events and meetups on robotics, compute, AI and whatever else is interesting, and people come to cowork, show their prototypes and trade ideas.
Patents
I hold more than 60 patents in the US, Europe, China and Israel, most of them on the sealing and vacuum technology behind our products. They are listed on Google Patents, Justia and InventorBook.
Investments
I've invested in Netlify, Stackbit, Flytrex, Bzigo, Bottomless, Numina Studio, Zellify and Cloud Compiler, and I like helping hardware founders get from prototype to production.

About
I studied mechanical engineering at the Technion and have been building hardware ever since. When I'm not working, I fly paramotors and build things in my workshop.
