The verdict
For a small B2B team, pick Loom. It is free to start, anyone can record without training, and five minutes of video often replaces a meeting. The habit is the hard part, so agree on naming and folders early.
If you run a large advertising budget across retail media, search and social, and you have people who will work in the platform every day, pick Skai. Its entry tier assumes ad spend in the millions each year, so it is not a tool to try on a modest budget.
If your ad spend is small and mostly B2B lead generation, neither is the answer to that. Use the native ad platforms, perhaps with a lighter optimisation tool, and keep Loom for explaining the results to your team.
