Founding Marketplace & Operations Lead

About Neptune

Neptune is building the concierge couples trust to navigate the biggest decisions of a life together. We pair emotionally intelligent AI with vetted legal and financial experts and transparent pricing, so both partners can make confident, fair decisions together and build a life—and lasting wealth—as a team.

At the center is a shared operating system for couples that remembers everything for you, so you never repeat yourself and every next decision starts from what we already know. Couples make billions of dollars in financial and legal decisions over a life together, and no one has built the trusted companion that carries the full picture across all of them. That's the category we're defining, and it's a rare moment to help build it from the ground up.

Our team comes from Stripe, Google, Palantir, and Uber. We’ve raised $7.5M from Floodgate (Lyft, X, Twitch) and The General Partnership, and demand is growing fast.

You will lead Neptune’s expert marketplace, owning expert recruitment, supply partnerships, and ongoing marketplace operations.

Working directly with the founders, you’ll help us enter new markets, build relationships with experts and partner organizations, and improve how our marketplace runs.

What success looks like: We have the right experts available to serve our customers, productive partnerships, and a reliable process for entering new markets. You know how the marketplace is performing and take action when something needs to change.
