Wealth arrived faster than the infrastructure to manage it.
A generation is earning and building wealth on their own — and the systems built to support that are still catching up.
Too complex for DIY software. Not yet at the stage that justifies a family office. A filing-only relationship can leave planning and coordination to you.
So We Built the Infrastructure Ourselves.
Built for the gap in between.
Not TurboTax with a nicer interface
Software files what already happened. It doesn’t think ahead.
Not a traditional CPA firm
A filing-only relationship can leave planning and coordination to you. Butter helps you plan before decisions are made.
Not a wealth manager or family office
Butter focuses on personal tax preparation and proactive planning, and can work alongside your existing financial advisor.
Butter sits here — built for people who've outgrown one and don't need the other yet.
Five Things That Shape Every Decision We Make With You.
The gap in between
An entire generation is earning faster than the systems built to support it. You’re not behind — the infrastructure is.
A coordination problem, not a tax problem
Brokers, bankers and CPAs often focus on their own piece. A filing-only relationship can leave planning and coordination to you. Butter looks at the whole picture.
April is too late
By the time you file, the decision’s already made. Real planning happens months before the return, not during it.
“Fine” is expensive
You’d fire a trainer or a barber the moment they became just fine. The person guarding your biggest financial decisions gets a pass — because fine feels safe. It isn’t.
Tech does the mechanics. Humans own the strategy.

Meet JZ Zhang, Founder of Butter
JZ began her career on Wall Street, where she saw firsthand how quickly financial lives evolve as careers and wealth grow — and how often the services supporting them fail to keep pace.
She went on to build consumer technology businesses and serve as COO of Charm, a developer tools startup backed by Google's AI fund, Gradient Ventures, where she gained early exposure to large language models and their potential to transform traditional services.
She founded Butter around a simple belief: as your financial life advances, your tax relationship should advance with it. By combining modern technology with experienced tax professionals, Butter brings a more proactive, personal approach to managing taxes.
