At SpeedCurve, we focus on measuring the interplay between design & performance to help you deliver a great, enjoyable and fast experience to your users.
Measuring web performance started 15 years ago with metrics like page load time and total download size. But today's websites and browsers have changed a lot since then. Ajax, lazyloading, preloading, async-loading, custom fonts, and responsive design mean today's websites are more complex. It's been shown that those old metrics no longer correlate to a good user experience.
SpeedCurve's goal is to deliver metrics that give true insight into what users are experiencing. Led by Mark Zeman, a teacher, director & leader in the world of design, and Steve Souders, pioneer of the web performance movement, SpeedCurve is innovating new metrics for tracking how design and code changes affect what users see and how quickly they see it. This combination of focusing on design & performance is highlighted by dashboards that include:
We help developers, designers and managers demonstrate to the wider organization how fast (or not) the user experience is and how you compare to the competition, enabling you and your team to make better informed decisions.
Mark comes from a design background but has always been just as passionate about the code. He has spent 20 years crafting websites and mobile apps in a variety of roles, including running his own design studio, lecturing at New Zealand's best design school and leading teams to deliver some on New Zealand's largest websites as a creative director in a digital agency.
He is a prominent thought leader in the performance community and popular on the conference circuit where he evangelises the role of design in improving engagement with performance issues. Here is Mark's latest Velocity Conference talk on better performance through better design.
Steve is a pioneer in the world of web performance. Before SpeedCurve, he held positions as Chief Performance Yahoo!, Google's Head Performance Engineer, and Chief Performance Officer at Fastly. Steve "wrote the book" on web performance with High Performance Web Sites, and its follow-up Even Faster Web Sites. He is the creator of many performance tools and services including YSlow, the HTTP Archive, Episodes, ControlJS, and Browserscope. He taught CS193H: High Performance Web Sites at Stanford University and serves as co-chair of Velocity, the web performance and operations conference from O'Reilly.
Cliff is a long time web performance advocate who has spent the majority of his career building tools and products that drive performance culture. He was an early advocate of Steve’s first book during his time at Keynote Systems where he consulted with some of the world’s largest brands to implement front-end best practices. With the desire to drive culture from the front lines, he joined @walmartlabs where he led the Performance and Reliability team who was responsible for significant improvements in front-end performance and backend scalability.
Most recently, Cliff served as a senior product executive at both SOASTA and Akamai where he was obsessively focused on improving the user experience by providing visibility, insight and value for the largest customers on the web.
Tammy has spent the past two decades studying how people use the web. Since 2009, she’s focused on the intersection between web performance, user experience, and business metrics. Her book Time Is Money: The Business Value of Web Performance (O’Reilly, 2016) is a distillation of much of this research (but there’s always more to be learned).
Tammy is a frequent speaker at events like Shop.org, IRCE, and Smashing Conference. She co-chairs O’Reilly Fluent, the conference for anyone involved in building the modern web. She also co-curates WPOstats.com, an ongoing collection of performance case studies.
Joseph is a developer with a diverse background ranging from small web agencies to video streaming services to large organisations like the BBC and Time. His experience has helped him to understand that performance is as much an organisational and communicational challenge as it is a technical one.
