Thanks! Yes! We realized that early teams don't even have a data stack — they just rely on dashboards built into the tools they already use. The problem is, there's a dashboard on every tool, which means these teams have to hop between multiple tabs/dashboards to get a complete picture. We've built a way to view these metrics in a single place.
Segment doesn't have a built in visualizing layer, and relies on destinations to handle that (like Mixpanel, etc)— but even there, non-technical operators are lost because they have no mental model of how to transform a stream of events into something like, say, "Activation rate" or "Retention curve". We connect to Segment and have pre-written the SQL required to generate these commonly used metrics.
Those CSS frameworks only enable startups to rapidly prototype an MVP without an in-house design team. It allows them to work on what they enjoy and on what makes sense considering their skillets. It would be harder if those frameworks wouldn't exist.
On the other end, when a company grows towards maturity, it makes sense to have a design team for all their products that can experiment and design specific elements that are consistent not only between themselves but also with their branding, mission and strategy.
