About River AI
Our Mission: Redefine how modern brands grow in the era of AI.
Founded in 2025 in Switzerland & Spain by a Forbes 30 Under 30 entrepreneur and an ex-Silicon Valley AI engineer, River is building AI-native growth infrastructure for modern businesses.
There's a massive gap between what AI can already do. Think of autonomous agents, intelligent orchestration, self-improving systems and how most companies still operate: fragmented tools, manual workflows, reactive decisions.
River closes that gap.
At the moment, we're a team of five with our first paying customers already live in a high-ticket niche (aesthetic medicine & plastic surgery).
Now we're looking for the person who'll take River from invisible to impossible to ignore.
Your Opportunity
* You won't be joining a marketing department.
* You will help build it.
* You will work directly with experienced founders to shape how River is perceived by customers, investors, and the market.
->
You'll own the story, the content, the launch, and the first layer of brand distribution.
If you're looking for a role where you can have REAL IMPACT and help build something from day one in an AI native Startup, this is it.

* Help launch River publicly and establish credibility in the market
* Build relationships with potential clients and industry leaders (likes, follows, comments, ...)
* Test and optimize paid campaigns (MetaAds)
* Track performance and report on key growth metrics
* Help shape River's website, positioning and messaging
* Bring ideas, challenge assumptions and push us forward :)
