About Flex: AI-native private banking for owners

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 They’re stuck with outdated banks and fragmented tools.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 building its lifecycle marketing function from the ground up. We're looking for someone who can own both the strategy and the technical infrastructure behind how we engage prospects and customers across the credit application journey, banking, AP automation, and our broader product suite.

This is a builder's role: you'll be the first dedicated owner of lifecycle marketing at Flex, working directly with RevOps, Engineering, and Data to design the systems, not just the campaigns, that will power retention, activation, and growth as we scale. You'll partner closely with the Director of Revenue Operations and Head of Revenue to shape lifecycle strategy, while also being hands-on in Braze, Segment, and our data infrastructure — there's no team to hand this off to yet, so you're doing the thinking and the building.

Flex doesn't have a dedicated product marketing team today, so this role also owns messaging — not just the systems that deliver it. You'll need to be comfortable using AI tools to accelerate copy drafting, and working directly with Product, Legal, and Compliance to shape and approve messaging for a regulated fintech audience, rather than relying on a product marketing team to hand you finished copy.

Because lifecycle touches so much of the customer journey, this role also needs to partner closely with Product to establish clear lines of ownership — what communications live in-product versus in lifecycle channels, and why.
