Our philosophy

Focus on your product. We'll perfect how every user experiences it.

If you're working with us, you're world-class at something, and it's probably not web design. We optimize, monitor, and identify the gaps in your digital experiences so you can stay focused on delivering the products and services that make your business great. Let us make you world-class here too while you work your wheelhouse.

When someone comes to your site or opens your app, they'll browse, discover, and fall in love with what you make in whatever way is most interesting, engaging, and resonant to them. Not the way that worked in last quarter's redesign. Not the way your median user prefers. Their way, learned from how they actually behave, tested honestly, and improved every week.

Our personal motivation

All software is fundamentally inaccessible to some portion of its audience today. It's too expensive to run the experiments needed to fully understand your entire customer base and too expensive to build and maintain multiple high-quality experiences for different user groups. So companies build for a few target users instead of crafting great experiences for every unique group.

We believe simple, accessible user-level personalization should be available to all businesses. Language models finally make the economics work: when generating and validating a new candidate experience costs nearly nothing, every user group becomes worth designing for.

We got here through accessibility. It's the founding story, and it left us one conviction we build on every day: interfaces built to fit the people who need them aren't a niche. They're simply better interfaces. Personalization done right is accessibility at scale.

So we lower the friction, lift the engagement, and keep your technology from ever getting between your product and your users. One interface at a time, that makes all of the world's technology more accessible, empowering, and engaging for everyone.

A retiree in Mobile and a teenager in Connecticut can move through your store in exactly the same way.
On paper they're different customers. In your product they behave like the same person, and behavior is the only thing we build on.

Our commitments

Your brand stays yours

Experiments live inside guardrails you declare. Fixed elements stay fixed; brand rules are enforced mechanically, not by hope. Nothing unvetted ever reaches a user.

Non-demographic by design

We don't care who your users are or what their ad profiles say they buy. We care how they actually interact, because there are other people like them, and we can tailor each experience around interfaces already polished on their peers. And when someone fits no cluster we know, they don't get mislabeled. They seed a new one.

Winning recommendations, not endless dashboards

Monty-UX never raises an issue without a clear fix in hand. Every flag arrives with a proposed treatment your team can review, approve, and ship.

Grounded in formal proofs

We don't just claim it works. The core results, including a proof (via Blackwell's theorem) that personalization lower-bounds revenue, are written up in a formal whitepaper and shared with design partners. Request it.

Sound like your kind of philosophy?

We're partnering with a small set of teams who care this much about their users.
