About Ramp Ramp is building the smart infrastructure for finance teams, embedded in the transaction flow of every dollar a business spends. We automate how over $200B in annualized spend flows in and out of 70,000+ companies: authorizing payments, flagging risk, categorizing spend, and closing books. The problems are high-stakes, data-dense, and unforgiving. We hire people with high agency and high urgency. We look for slope over intercept. We care less about where you trained and more about what you’ve built. At Ramp, everyone is a builder who owns problems end to end and makes consequential decisions that shape the outcome. The median Ramp customer saves 5% and grows revenue 16% in their first year – far in excess of businesses operating without Ramp. We believe every ambitious company deserves the same. If you want to build systems that directly shape how companies move and manage billions, Ramp is the place to do it. About the role Ramp already serves thousands of organizations in industries where financial operations work differently: construction companies that manage spend by job and cost code, nonprofits that report by fund and grant, and public-sector organizations accountable for every taxpayer dollar. We are hiring a Lead Product Marketing Manager, Verticals to turn those differences into a durable growth advantage. You will own Ramp's vertical GTM operating model, beginning with Construction / A&E and Nonprofits / Public Sector. You will decide where Ramp should invest, become the resident expert on how finance works in those markets, influence the product roadmap, and build the cross-product narratives and motions that help Ramp win. This is not a content-only, campaign-only, or sales-enablement role. You will own the full vertical business read: market choice, ICP, product readiness, positioning, pipeline, win rate, activation, adoption, attach, campaign performance, and the next product or GTM intervention.
