Flex is building the AI-native private bank for business owners .
We’re re-architecting the entire financial system for entrepreneurs—from the first dollar a business earns to how that value compounds, moves, and is ultimately spent in real life. Banking, credit, payments, personal finance, and financial operations—rebuilt from the ground up as a single, intelligent system. Flex is the full financial home for ambitious owners.
Since launching publicly in September 2023 , Flex has scaled from zero to nine-figure annualized revenue , with a clear path to profitability by late 2026 . We move fast, ship relentlessly, and operate with extreme ownership.
Our customers are affluent business owners ($3–$200M in revenue) —the backbone of the economy and one of the most underserved segments in finance. They’re stuck with outdated banks and fragmented tools. We’re replacing all of it. The opportunity is massive: a ~$1T+ revenue market hiding in plain sight. Our ambition is to build a $100B+ company by delivering a product that is fundamentally better—not incrementally improved.
Flex has raised $100M+ in equity and $300M+ in debt.
Mission-critical problems : We build software that directly controls how money moves at scale.
High bar, low ego : Small teams, exceptional people, real ownership.
Speed over comfort : We prioritize execution, quality, clarity, and results.
Enduring impact : What we’re building will define how a generation of owners runs their businesses.
Team & Locations
We hire exceptional people who want to build hard things and see their work matter immediately. Roles are available in: San Francisco, Miami, New York, and fully remote.
Flex Fuels Ambition.
About The Role
Flex is hiring a General Manager to build and run its venture and private equity business. You own the sector end to end: the strategy for winning it, the relationships and partnerships that open it, the product priorities it needs, and the P&L it produces. You build on Flex ’s platform, balance sheet and teams, and you are responsible for making Flex the primary financial institution for venture and private equity.
The role is modeled on sector coverage at an investment bank. You decide which relationships matter, which partnerships can move hundreds of owners onto Flex at once, and what the product must deliver to win them. Flex ’s product, credit, risk and member experience teams execute and service alongside you. The role reports directly to the CEO.
Funds are the most efficient path to hundreds of owners at once. A sponsor that standardizes its portfolio on Flex , or a venture firm whose founders bank with Flex from their first wire, delivers in one decision what would otherwise take a hundred. The decision sits with general partners, fund CFOs, operating partners, fund administrators and fund-finance lenders. The General Manager owns those relationships.
What You'll Do
7 to 12 years in investment banking, private credit, private equity, venture, or a senior commercial seat inside venture and private equity. You have a demonstrable record of originating business, not servicing it.
An active network in venture and private equity. You can name the 50 people who matter and most of them would take your call this week.
Fluent in how funds and their portfolio companies move money: capital calls and distributions, portfolio treasury and credit, operating-partner priorities, and what a portfolio CFO requires to move a banking relationship.
Comfortable structuring partnerships, negotiating referral economics, and working through a term sheet without support.
You build your own models. Banker-level Excel and a working understanding of the unit economics of deposits, cards and credit.

How To Prepare
As part of the application, please be prepared to submit a one-pager along with your CV on how you would bring venture and private equity to Flex . It should cover:
The sector and its owners. Who they are, how many of them fall in Flex ’s range, how they make money and where their capital gets tied up.
What they need from a bank. The products and terms that would make owners in the sector move their primary relationship, and in what order.
The map. The 20 to 30 people and institutions that move the sector, and how many of them you know personally.
The first three partnerships. The programs that would put hundreds of owners on Flex at once, and why each counterparty would say yes.
The investment and the return. A light P&L for the sector: what Flex would need to put in over the first two years (people, product, partnership economics, marketing) and how that investment comes back, in the form of owners banking with Flex and the revenue they produce. We are looking for the shape of the business and the logic behind it.
The plan and the team. How you will build this out and what you will need to do it.
Treat it as a coverage pitch. Bring the map, the partnerships and the economics, and be ready to defend each one.
