Fintech startup Tally has started to see big success in advertising on TikTok which has allowed the company to more efficiently acquire customers; the cost to get a user to download the Tally app is 300% cheaper when running ads on TikTok versus Instagram, the company said; “When we started to talk about testing out TikTok, it was a lot of people saying, ‘Isn’t that just for kids?'” said Nick Weinberg, a Senior Paid Acquisitions Manager at Tally, to Business Insider. “What we found from this campaign, and anecdotally, is there are a tremendous amount of adults on this platform.”; Tally is amongst a small group of fintech startups using the platform as they try to appeal to younger customers where they spend their time.
