How It Works
Sidekick manages your closet with advanced machine-learning software. We built the first public Poshmark automation tool over 6 years ago and have been learning how real people behave on Poshmark ever since — so your closet grows the smart way, not the spammy way.
Everything you’d want to do on Poshmark — done automatically, intelligently, and safely.
Safe & Compliant
We solve captchas for you, continuously assess and re-assess your potential for shadow-bans, and our core software automatically slows down and takes smart breaks if it detects the slightest risk of share-jail.
That’s why you’ll never get into trouble with Poshmark. We stay compliant by mimicking human behavior — because we’ve been studying how Poshers actually behave for over 6 years.
Beyond Poshmark
Stop listing the same item 7 times on 7 different marketplaces. With Sidekick Crosslisting, you list once and we push it to every marketplace you sell on — automatically. When an item sells, we delist it everywhere else so you never double-sell.
If you can push a few buttons, you can order from us. Here’s exactly how it works:
Our software and systems are hundreds of times smarter than every automation tool out there. We won’t name names, but almost all of them try to copy our technology and ideas. We were first — and we’re still the most advanced.
Join thousands of sellers who’ve turned their closets into real businesses. Automation, crosslisting, and smart growth — all in one place.
