Founding Marketer

About Us:

a0.dev is an AI platform that turns app ideas into real, revenue-generating mobile apps. Users enter their idea and our AI designs, codes, tests, and ships it to the App Store, handling everything from infrastructure to deployment in one place. We were one of the first AI mobile app builders in the market and have helped over 300k people bring their ideas to life. We’re a small, well-funded, in-person team in San Francisco backed by Y Combinator and other top investors. We believe the future is one where anyone can invest in their ideas regardless of technical experience, and we’re building a platform that helps people not just create apps, but launch them, market them, monetize them, and turn their ideas into real businesses that reach millions of users.

The Role

We’re looking for a Founding Marketer to help scale a0.dev and lead the launch of our next product. You’ll work directly with the CEO to bring something new to market, shape how we position it, and get it in front of the right people. This is a generalist role spanning product, performance, and brand marketing, where you’ll take our early traction and turn it into real growth by creating content, running campaigns, talking to users, and driving distribution wherever it works.

You’ll be deeply involved in the early days of this new product, helping us find product-market fit through rapid iteration, tight feedback loops, and constant experimentation. We’re a small team moving quickly, and this role will help build the foundation for how marketing works at a0.dev as we grow from serving hundreds of thousands of users to tens of millions. You’ll have real ownership and play a key role in scaling the company and defining how we reach and impact a global audience.

What You’ll Do:

• Build and execute a plan to launch and scale our next product
