Solid for our team

We rolled this out across the team last quarter and it is genuinely easy to set up. The core workflow fits neatly into how we already work, and the API removed a step we used to do by hand. Pricing gets steep at scale, which is the main caveat, but it has held up under daily use.

Use it every day

Honestly didn't expect to like it this much. The core workflow is exactly what I needed, and it is genuinely easy to set up. but I reach for it almost every day now and it just clicks.

Use it every day

Honestly didn't expect to like it this much. The automation is exactly what I needed, and support is responsive. I do wish a few rough edges remain, but I reach for it almost every day now and it just clicks.
