Andrew Gazdecki knows startups. He founded Bizness Apps as a broke, twenty-something entrepreneur and sold it to a private equity firm before the age of thirty—after going head-to-head with Apple over a blanket App Store policy that threatened to ruin him.

He’s been a growth consultant for several more multimillion-dollar startups. His companies have been featured in TechCrunch more than a dozen times.

Now, he shares his remarkable story in Getting Acquired: How I Built and Sold My SaaS Startup. Follow Gazdecki’s journey: starting a company at the age of twenty-one and hiring, then leading, over one hundred employees without any real work experience of his own.
