Text on a blue background: “SpeedCurve is a great tool — and 75% of the value we get is from our check-in sessions with their team! In our internal quarterly State of the Stack meetings, Speedcurve gets the most consistent accolades as a helpful resource. The platform, and the actual guidance from actual people, has enhanced our website and the knowledge of our team. The check-ins with Cliff are something special: on the calendars as optional for most of the team, yet everyone attends. Working with Speedcurve has allowed us to streamline our monitoring stacks because it is so comprehensive. We don’t need as many tools as we thought we did."

Quote from Michelle Vu, a performance engineer at Pinterest:"Fighting regressions took priority over optimizations. The reason we decided this was because in the past, when we had performance efforts, engineers who were working on optimizations couldn't really see progress in our performance metrics, because there were so many regressions happening at the same time."

Testimonial quote from Elliot Crush at Holiday Extras:

"SpeedCurve is worth its weight in gold. It highlighted performance bottlenecks and benchmarked us against competitors. We discovered an issue with blocking scripts in our SPA and improved performance by 40%. So valuable for securing stakeholder buy-in."

Screenshot of a quote attributed to Rockey Nebhwani of Walmart:

"Had a third party degrade web performance and for alerted by SpeedCurve. Raised the issue with the third party and they fixed it. Metrics now back to normal!"

Next to it is a LinkedIn comment from Joan Leon, Staff Frontend Engineer at Adevinta:

"I love it. 🤩 This helps us to be able to create alerts on redirection times."

1. Get people to care about web performance in general.
2. Get people to care about the performance of your site in particular.
3. Involve people in making things better.
4. Celebrate wins.

Screenshot showing the glossary definition for Largest Contentful Paint. Largest Contentful Paint is provided by browsers via the Largest Contentful Paint API. It's the time at which the largest element in the viewport is rendered. It's only tracked on certain elements, e.g., IMG and VIDEO (see more here). As of August 2019, this is available in Chrome 77+. Largest Contentful Paint is one of Google's Core Web Vitals, along with Cumulative Layout Shift and Interaction to Next Paint. LCP may be present for a SPA navigation if the LCP candidate rendered during the transition is larger than the previous LCP. This is not considered a reliable metric for SPAs given that is it not a true 'continuous' metric.
