Velt’s commenting & notification features are bundled with a lot of magic
Velt gave us 1-on-1 attention in our own private slack channel. The team was quick to add new features that we needed (thanks for the category feature!) We were extremely happy with how customizable Velt’s components were, allowing us to keep a cohesive look and feel to our product. Highly recommended.

Increased weekly active users by 26%
Velt boosted our weekly active users by 26% and saved us atleast 6 months of development. Velt has the foundation of everything we needed — so building it in-house just didn't make sense. Everything was a smooth experience — especially because the Velt team has been super responsive and collaborative!

Increased engagement by 10% and helped ship 5x faster.
Took about a week for the implementation. The speed of iteration from the Velt team is incredible compared to alternatives, they're always happy to discuss and find a solution. The Velt team was extremely supportive and responsive to feedback. Docs were clear and easy to understand.

Saved 3 FTEs & will boost retention
Implementing Velt took weeks, not the quarters it would have taken us to build in-house, even with 3 FTE engineers. We're already seeing added value for our users and anticipate increased retention. Velt's product is slick, and their team is incredibly supportive.

Saved massive development effort
Velt provides the critical commenting functionality our customers rely on, saving us massive development effort. Velt made migrating our commenting data from our previous vendor seamless. After evaluating other options, Velt stood out as the most compelling choice. They not only met our core requirements but also offered a wealth of additional features for future implementation.

Full collaboration features shipped in under 1 week
Building our own collaborative features was becoming an overwhelming task, so we were relieved when we found Velt. Their SDK included all the commenting and notifications features we needed, and were easy to integrate. We shipped comments in just a week, without having to build from scratch!

Boosted customer happiness.
Commenting is something that we knew we wanted in our app but with limited resources it wasn’t going to be prioritized. That is until we found out about Velt. The team was fantastic to work with.

We were able to launch 5x times faster than building from scratch.

With Velt, a single engineer could build comments feature in a few minutes.
Velt is outstanding! It helped us enable clear and quick communication with customers. With Velt, a single engineer could add comments in a few minutes without help from Product or Design. The docs were clear and straightforward. We spent only a few minutes making Comments work.
