Hi!

I’m Jonah Probell.

You can reach me at (first name)@probell.com

Professionally

My resume is available on LinkedIn.

I am a professional angel investor and patent strategist.

I have worked for 7 startups and small companies, two that I co-founded. My companies have been sued for patent infringement and lost, sued and won, and avoided being sued. I built a small patent portfolio that was sold for $50M and a large one that supported late-stage financing at valuations of more than 100x revenue.

I am currently looking for deals in AI, biotech, and SaaS types of business. But I will invest in any company that looks like it has an unusually good chance of an unusually good return. In the past, I have done engineering, sales, and marketing in the semiconductor, chip design, signal processing, and video codec worlds before moving to inventing and patenting in natural language and AI software.

As an investor, I offer patenting help to portfolio companies and some others. That can include harvesting inventions and performing due diligence on patentability and market value.

Personally

I seek to broaden my horizons. I often learn everything that I can about something new. Wikipedia is my favorite web site. I enjoy technical writing and teaching because that's the best way to learn a subject thoroughly.

I love that I have diverse friends and acquaintances. I view strangers as friends that I have yet to meet. I enjoy helping others. I will take either side for the sake of a good debate.

I enjoy cycling. I tend a fine garden. I watch live theater but not television. I like cloudy weather and wind. I am selective about what organizations I join.

I love to travel, have spent time in most US states and many nations of the world, and have a friend in each one. Though I wander, I spend most of my time in Silicon Valley. I am also licensed ham radio operator N1QLO.

I enjoy trying new languages, but I know only one fluently. Lately, I am studying Mandarin and reading traditional Chinese characters. I speak and write with impeccable English grammar. I enjoy limericks, wordplay, thoughtful sayings, and general trivia. I like studying maps and have a good sense of direction. I drive a stick shift and can back up a trailer.

If your name is Probell, please let me know, especially if you are interested in having an email address ending in @probell.com. Otherwise, just enjoy this site.
