Want advice on launching a startup?

Join a Wall Street Journal Spreecast video chat at 3 pm EST Friday to get your startup questions answered by a diverse group of mentors – successful founders, investors and entrepreneurship educators. You’ll get advice and insights about the best practices and common pitfalls of starting a company.

This week’s chat features The Accelerators contributors Steve Blank, an eight-time serial entrepreneur; David Tisch, managing partner of BoxGroup, a seed-stage angel-capital firm; and guest mentor Dan Porter, former chief executive of OMGPOP, a social and mobile gaming company that was acquired by Zynga Inc. in March. In addition to taking questions from viewers, they’ll cover topics such as the art of business-plan writing, the startup funding debate and other startup essentials.

To join the conversation — and RSVP for a reminder to join the chat — simply follow this link and sign in with your Twitter or Facebook account.  Then, you can post questions or chat with us and even come on screen and let us know what you think.

Highlights of the mentors’ insights this week:

Steve Blank: No business plan survives first contact with customers.

David Tisch: The most valuable thing to spend time on before starting the company is the market, not the idea.
