About Unusual

Unusual helps brands discover and change how AI models talk about them.

People are increasingly using AI to make big buying decisions in their life – but brands have no control or visibility into what AI is telling their customers. Unusual puts control back in brands’ hands.

We work with fast-growing companies including Reducto, Monarch, and more, and our team has experience from MIT, Princeton, and SpaceX.

Under the hood, Unusual surveys models with thousands of targeted probing questions to understand how they form their opinions. We examine the sources they pull from, and find patterns in their reasoning that let us create content and PR engineered to change those models' minds.

A typical Unusual customer sees more than a 40% increase in traffic from AI models within a month of going live. Our customers have used Unusual to shift models' perception of their brand from "niche" to "enterprise-platform", from "scrappy" to "customer-obsessed", and from "good for startups" to "a solid bet for the middle market".

The Role

Skills: Python, TypeScript, AWS, experience with LLM applications, Docker. Being a hacker – enjoying getting stuff done independently.

Scope: You’ll work with the founders to understand customer needs and product bottlenecks, and translate those into an engineering roadmap for the team to chase down. It’s an early stage company, so you’ll be wearing many hats.

Why work at Unusual?

  • You have a chance to help define an entire new technical field and market. We're essentially doing applied psychology on LLMs. We think that's pretty cool, and extremely valuable.
  • We're riding a huge tailwind. While many AI companies may be threatened by a bubble, we think the usage of tools like ChatGPT is only going to increase. The need for our product is only going to get greater.
  • We aim to be the premium solution in the space -- we pull no punches when it comes to making the product smarter and better, and pricing accordingly. As an engineer, this means you can do your best technical work at Unusual.

Culture and Values

  • Character comes first. We only work with people we deeply trust and respect. We think this makes work more fun, freeing, and effective.
  • We try to remain down to earth and in touch with customer's real pains. Everyone at Unusual works in the customer service department.
  • We do whatever it takes. When we know what we must do, we don't take shortcuts or shy away from huge ugly challenges. That means we work pretty hard, and occasionally have to do some big sprints.
