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 AI brain 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.
We've raised $7.5M from Floodgate (Lyft, X, Twitch) and The General Partnership, and demand is growing fast. We're hiring our first founding engineer to build the brain and the product every couple will trust with their most important decisions.
You'll be turning something emotionally fraught, legally complex, and deeply personal, a conversation most couples avoid entirely, into a product people actually trust and enjoy using. You'll design conversational AI that handles sensitive financial and emotional context with care, wire LLMs into real legal and financial workflows, and make outputs that have to be not just correct but have high credibility and trust to act on.
You'll own features end-to-end (architecture, frontend, backend, deployment), and your decisions will set the technical foundation for everything Neptune becomes.
You'll work directly with the founding team (former Google, Stripe, Palantir, Uber, Thirty Madison) and talk to real users every week, watching what you ship change how couples make their most consequential decisions. Work is organized around the problem it solves, not where it sits in the stack.
