The team

The people who will actually be on your account.

Every engagement is led by a controller who knows your business. You are not handed to whoever happens to be free that week, and you are not emailing a shared inbox.

Leadership

Jack Hau

Partner, CPA

Jack is a CPA whose background is technical accounting and helping companies through funding and IPO readiness. He is who we turn to when a transaction is unusual, a revenue arrangement is complicated, or an auditor is going to ask a hard question. Jack works with the controller team on the accounting positions that have to hold up under outside review.

Taryn Yee

Partner, CPA

Taryn is a CPA who works across operations and business development. She spends her time on how engagements actually run, from scoping new work through to keeping delivery consistent as the firm grows.

Andy Lau

Managing Partner

Andy runs the firm day to day. His career has been in building product platforms and leading business operations, work that comes down to making systems produce reliable results at scale. He brings the same emphasis here: how the work gets done matters as much as whether it got done.

The senior people who own your numbers month to month.
