Flush — Built for founders. Not accountants.

Built for people QuickBooks forgot

Your income doesn't look like a salary.
Your tools shouldn't assume it does.

⚡

Fractional executives

You bill 4 to 8 clients on different cycles. Some retainers, some project-based, some equity. Your income is real but it's never predictable.

Which month can I actually pay myself?

Which options am I about to lose?

Why did tax season blindside me again?

🚀

Startup founders and CEOs

You're building while managing personal finances across entities, equity positions, angel deals, and a bank account that looks different every month.

What does my 90-day runway actually look like?

What am I worth if this company exits?

Am I leaving tax money on the table?

🏛

Independent consultants

Your biggest client pauses and your whole financial picture changes. You need a tool that thinks in probabilities, not spreadsheets.

What if my biggest client pauses next month?

Am I invoicing everything I should be?

When should I take a distribution vs leave it?

Tax intelligence

Your transactions know more about
your taxes than you do.

Early users

Built by a founder who lived every
one of these problems.

"Flush takes invoicing and cash flow uncertainty off my mind and adds productivity time to my day. A game changer for me and my business."

Rick Rusch

R2 Branding

"Flush is dramatically easier than QuickBooks for the way I run my business. I invoice my customers every month in just a few minutes instead of fighting with accounting software for hours. It's clean, intuitive, and finally feels like a tool built for founders instead of accountants."

Kristin Stanford

Artist

"Flush is the first tool that lets me track my options and hold founders accountable for the equity commitments they've made. Something I've never been able to do reliably until now."

Your data is yours

Built with privacy at the foundation,
not bolted on after the fact.

A lot of people ask if we can see their financial data. The honest answer is no, and here is why that is true by design.

🏦

Bank connections via Plaid

Your bank credentials never touch Flush. Plaid, the same infrastructure used by Venmo, Coinbase, and most major fintech apps, handles authentication and passes back read-only transaction data.

🔒

Your data is invisible to everyone else

Every query in the database is scoped to your account using Row Level Security. Not even the Flush team can run a query that returns your data. Your numbers are yours only.

💳

Payments via Stripe

Card details never touch Flush servers. All payment processing runs through Stripe, which is PCI Level 1 certified and used by millions of businesses worldwide.
