Heepsy is a flexible search tool that also lets you find influential brands on Instagram. If you'd like to see brands, click Show only brands.
But if you're not interested in finding brands, and only want to see influencers, no problem. Click Show only influencers to avoid seeing brand accounts.
You can also choose to see only accounts that Instagram has verified. Mark the checkbox Show only Instagram verified to do so.
When you're analyzing profiles, it's easy to see if an influencer is verified. Look for the blue checkmark icon next to their name.
