About My High Tech Startup blog (

These writings are meant to provide some information (and
occasionally an insight or two) to individuals involved in the
entrepreneurial world. Entrepreneurs, investors, techies, inventors,
lawyers, accountants, futurists, bankers, candlestick makers, lovers,
fighters, Olympians and anyone else who stumbles across this page
wondering where to find Seattle on a map may find this useful. The blog
will cover topics ranging from legal issues faced by startups to trends
in venture capital to a sense of the Seattle entrepreneurial community
to my own personal interests in technologies or life. If there is
something that you’d like to see or a question you’d like me to try and
answer, just let me know. I’ll do my best.

You’ll see some great cartoon images here on the site.  Thanks to Kansas City artist Travis Fox who drew the images you see here and provided the images in the book.

What Every Engineer Should Know About Starting a High Tech Business Venture

That’s the title of a book I’ve written (yes, it is a bit long, but it is part of a series… so
think “Starting a High Tech Business Venture” for short. This website
also contains previews of chapters of the book, documents you can
download that are referenced in the book, and information I would have
liked to cover, but there just wasn’t enough room. I may be biased, but
I think the book is a good resource and hopefully, in conjunction with
this website, becomes an even better one.

    How impressive can an attorney be? Eric seems to set the top of the gauge. Incredibly resourceful, communicative, and engaging, Eric is wise beyond his years. Eric's knowledge of business is one that develops from being engulfed in an idea, taking it all the way from conception to completion. I strongly suggest that any client contact Eric with their business creation or joint venture questions - he will guide you the right way.
