## Why this can grow

Whatnot’s growth story is a format-expansion story. Vogue Business discusses fashion sellers using the platform, while Whatnot’s State of Livestream Selling Report frames live selling as a broader seller growth model. The key is sequence. Prove live auctions in a category where the behavior is natural, then ask which adjacent categories share the same need for community, explanation, urgency, and seller personality. This avoids launching every category cold. It also keeps the company honest: if a category does not benefit from live performance, it may belong in a normal marketplace instead.

## Ian's take

From scaling consumer platforms across MENA and Southeast Asia, my default is to distrust growth work that only looks good in a slide. My bias is to treat this as a small market test first. Make the audience narrow, make the promise concrete, and let the first real response decide whether it deserves more work. I would run it small enough to learn quickly, then only scale the parts that real users repeat, save, reply to, or buy from. For this tactic, I would watch one clear growth signal before putting more time or budget behind it.

## Action plan

1. Define one narrow startup segment where whatnot category expansion after show format proof can create a measurable lift.
2. Turn the tactic into one offer, page, campaign, or workflow for the Category Expansion and Live Commerce channel.
3. Use the evidence from blog.teamwhatnot.com to set the first version of the message, format, and audience.
4. Launch a small test for 7 to 14 days with one success metric: one measurable growth signal.
5. Review the result, keep the winning message, remove weak variants, and turn the learning into a repeatable growth playbook.

## Source-backed example

Whatnot expanded beyond early collectibles into categories such as fashion and broader live-selling verticals after the live-auction format had already proven buyer and seller behavior.
