Upfluence

Upfluence is a professional influencer and creator marketing platform built by the company of the same name, which has been in the field for years. It's aimed mainly at brands, e-commerce stores and agencies that want to work with creators systematically and measurably, not through random DMs. It fits the moment when handling collaborations by hand in spreadsheets stops scaling and you need a proper tool.

It works by letting you define the kind of creator you're looking for, then searching a huge database of profiles across networks like Instagram, YouTube, TikTok and Twitch. You can filter by topic, audience size and demographics, engagement rate and location. The output is a list of relevant creators, and during campaigns the platform continuously measures reach, sales via discount codes and overall return.
