Craft and Beauty: Discovering the Value of Form in Function | Stripe Sessions

1. What Is "Craft and Beauty"?

Katie Dill opens her presentation by pointing out that many people dismiss "Craft and Beauty" as merely a "nice-to-have." However, she emphasizes it as an "essential element," not a mere add-on. Using the early Model T as an example, she explains that while basic functionality alone was sufficient back then, today's cars rely on details like leather, stitching, and the sound of a closing door to differentiate between "premium" and "ordinary."

"Craft and beauty isn't a nice-to-have, it's a must-have."

One of the reasons Katie joined Stripe was that "craft" was one of Stripe's operating principles. Stripe doesn't simply pursue beauty — it values craft and quality as the foundation of user experience in building financial infrastructure.

2. Misconceptions About Quality and Beauty

Katie addresses several "misconceptions" about quality and beauty in her presentation.

1) The Misconception That "Beauty Is in the Eye of the Beholder"

Katie argues that beauty is not entirely subjective. For instance, blue is frequently cited as the most beautiful color, and circles are considered the most beautiful shape. This demonstrates that a certain degree of objectivity exists in how people perceive beauty.

Using a Mondrian painting experiment as an example, she explains that 85% of audiences worldwide could distinguish genuine works from fakes. This was because Mondrian meticulously worked to find "objectively more beautiful" compositions.

"Does it really matter what the layout's like, or the color, or the type choices? Yes, there probably is an objectively more beautiful solution that your users will appreciate more."

2) Is Beauty Merely Skin Deep?

Quoting Steve Jobs, Katie emphasizes that design is not just about "how it looks" but about "how it works." Beauty is not merely a visual element — it contributes to enhancing usability and engagement. Through Stripe's email design improvement case study, she shows that visual improvements and linguistic refinement increased product conversion rates by 20%.

"Things that are beautiful are perceived to work better. It's called the aesthetic-usability effect."

3. The Multi-Layered Structure of Product Quality

Katie compares product quality to the structure of a house, explaining that quality operates at multiple levels.

1. Foundation Layer: Basic structures like API design and infrastructure. A weak foundation affects the entire structure.
2. Structural Layer: Flow and organization, such as information architecture.
3. Functional Layer: Elements users directly experience, like buttons and interaction patterns.
4. Cosmetic Layer: Visual elements like typography and color.

"Craft and beauty matters at every level because they're all connected."

Katie mentions that her own house has a window leak problem, emphasizing that "if the foundation is weak, it will eventually show on the surface."

4. Stripe's Quality Culture: Friction Logging

Stripe improves quality through a method called "Friction Logging." Engineers, product managers, and designers use the product as actual users to discover "friction" in the usage experience. This helps them internalize why quality matters at every step and drives improvement.

"It becomes loud and clear how much the quality matters at every step of the way, and that it is not just on the surface."

5. The Correlation Between Beauty and Growth

Katie argues that "beauty and functionality are not at odds." Through Stripe's payment process improvement case study, she demonstrates that improving user experience led to an 11.9% increase in revenue. This was because detailed improvements — streamlined design, dynamic payment methods, one-click checkout — positively impacted both users and the business.

"Craft and beauty can drive growth."

6. Perspectives from Linear and Figma

Linear's Karri Saarinen and Figma's Yuhki Yamashita share their perspectives, resonating with Katie's presentation.

1) Karri Saarinen (Linear)

Karri distinguishes between "Craft" and "Beauty," explaining that Craft is a "mindset and activity" while Beauty is the "output." He emphasizes that quality requires not just technical ability but also "the right direction and ideas."

"If people are not raving about your product, you probably don't have a good product."

2) Yuhki Yamashita (Figma)

Yuhki explains that Figma's obsession with performance and frame rate laid the foundation for user experience. He emphasizes that a "cultural commitment to quality" is essential for product success.

"If you need an OKR to convince someone to care about quality, you probably have the wrong team."

7. Three Action Items for Quality

Finally, Katie asks Karri and Yuhki for three pieces of advice on improving "Craft and Beauty."

1. Share the belief in quality: Leaders must believe in the importance of quality and share this belief with the team.
2. Create space: Give teams the room to do deep, thoughtful work.
3. Embrace immeasurability: Pursue quality even when it can't always be quantified.

"Quality doesn't happen on its own. Someone needs to put the thoughtfulness and work in it."

8. Conclusion

Katie closes by reemphasizing that "Craft and Beauty" is not just about appearances — it is the core of user experience and business growth. Stripe, Linear, and Figma all internalize quality as culture, delivering value to both users and the business through it.

"Well-crafted beautiful things are more functional, and beautiful things support growth. It's not a nice-to-have — it's a must-have."
