We design & engineer
AI interfaces that stick
Jaw-dropping is the hook. Trust is the moat.
After 16 years, 300+ companies, and 3 unicorns, we know what makes users lean in—and stay.
What makes a product stick
Beautiful gets attention. Slop drives churn. Sticky earns a place in someone's life. If you wanna stick in 2026, your taste & style should lead to trust & outcomes. People don’t need more nicely designed features. They need results.
Trusted by teams designing what's next.
From vision to sticky product, together.
We're Anthony & Katie. We've Designed 300+ Sticky Products over the last 16 years.
Products people can't unsee. 3 AI unicorns. Value that's obvious on first contact.
Sticky products drop jaws and calm anxiety
The weight drops. Trust climbs. Users feel the product working before they learn how it works. Belief grows on top of relief.

“Setting up auth took us 10 minutes instead of 2 weeks. The SDK just works out of the box with zero configuration. Our team shipped the entire login flow before lunch. Best developer experience we've had.”
Sticky products reflect the audience's desires
The emotional geometry of switching — what pushes, what pulls, what finally makes change feel worth it.
Sticky products are more than boxes and arrows
We discuss how to shape your product to be more than the sum of its parts, then we help you ship it.
Sticky products have a no-brainer baby step
The baby step before the big commitment. Matched to the moment they're ready to move, resistance just melts.
Tomorrow arrived early
The right audience feels the future on first contact. Jaw-dropping interfaces where the value is impossible to walk away from.
The hole in tomorrow only your product fills
The incremental becomes the leap. The forgettable becomes the obvious choice.
Every round sharpens the product
Design anchored to the behavioral shift the product needs to create. Generative tools in service of outcomes, faster.

Products that became
hard to walk away from
Founders and product leaders who crystallized their vision and designed growth into their product.
Products that became
hard to walk away from
Hear from our community of builders, designers, and creators who trust us to power their projects.
“They're the best design team I've ever worked with.”
“Their process is a lot faster, more efficient, and has a higher likelihood of hitting the mark.”
“Just want to send you both a note to say I'm very impressed. I can see why everyone recommends you.”
“I've worked with agencies, I've worked with internal teams, I've worked with freelancers — this team goes above & beyond.”
“You guys are in the top 5% of designers I've ever worked in my life, and I've worked with the folks in Microsoft.”
“They really pushed and pulled on a new concept I was working on, helping my idea launch faster.”
How the crossing works
Design that ships. AI that earns trust. A bridge from where you are to where you could be.
AI that knows what the user actually needs
Responses shaped by what the user is trying to accomplish -- not just what they typed.
Figma ↔ Claude Code
Flows, states, edge cases, and tokens translated so design moves cleanly into implementation. Handoff becomes a conversation, not a translation project.
AI-Friendly Design System
Systems built for ambiguity, adaptive states, confidence signaling, and human override -- so AI feels trustworthy and native instead of bolted on.
Positioning that precedes the product
The right audience recognizes you before you explain yourself. Clarity that turns every conversation into a shortcut.
A category no one else is defending
Instead of fighting for inches in a crowded space, own the angle where you become the only option. The way Gamma did.
The value gap so clear it sells itself
When what you offer and what they need snap into focus, the product does the convincing. No pitch required.
