Hi! I'm William Pietri. I am a developer, entrepreneur, leader, and writer. I have spent more than a decade studying and practicing various Agile software development methods, and am now very involved in the Lean Startup movement.

I live in San Francisco and I am looking for something interesting to spend the next few years on, most likely as a CTO, VP of Engineering, or technical co-founder. I'm looking for an ambitious, impact-focused outfit with good people. Got a suggestion? Get in touch!

Contacting me

The best way to contact me is via email. Try my first name at this domain. Also feel free to message me on Twitter. If you're looking to book something with me, check out my public calendar.

I am also available for by-the-minute consulting via Clarity.fm.

About me and my work

To learn more about me, a good place to start is my LinkedIn profile. I comment occasionally on Twitter, and even more occasionally post to a group blog on Agile methods.

I participate in various nerdy forums, including the Lean Startup Circle and Balanced Team mailing lists. In the past I have been active on Wikipedia (where I was voted an administrator), Stack Overflow (4 gold badges) and Quora (Top Writer 2012 and 2013).

Social networks

People use social networks many different ways. I wouldn't want people to think me rude if I turn down an invitation to connect, so here's how I use them. Twitter is my general connect-with-the-public tool. Feel free to follow or at-message me on Twitter; I pay close attention to that. I use LinkedIn to keep track of people I have worked with and know well enough to recommend to others. I use Facebook for close personal friends, the kind of relationships where we'd attend each other's weddings. And you are always welcome to email me.
