About Build Accounting

Expert support whenever you need it.

Brett Rosenstein is the Managing CPA of Build Accounting. With 15 years of experience in the accounting and startup industry, Brett is a highly skilled Certified Public Accountant dedicated to helping startups navigate the complexities of accounting and taxes.

Build Accounting’s mission is to provide personal support to startup founders. We understand that as startup founders, you are not accountants. For this reason, we take care of everything on the accounting and tax side, so you don’t need to worry. However, if anything does come up, we are just one call, text, or email away.

One other focus is our responsiveness. After listening to hundreds of startup founders, we hear the same story over and over. Most accountants don’t respond to questions or aren’t proactive planners. For this reason, we differentiate ourselves by responding to each client as soon as possible. As a startup founder you deserve to have an answer in minutes, hours, or days, not weeks.
