Testimonials

Flippers love A Co

A Co paid for itself in the first week. Found a $40 vintage amp that I flipped for $280. The alerts are insanely fast.

Full-time Flipper

I was spending 3 hours a day scrolling Marketplace. Now I spend 15 minutes acting on the deals A Co sends me. Game changer.

Side Hustle Queen

The AI pricing is scary accurate. It correctly valued a set of mid-century chairs at $600 that were listed for $75. I made the flip that same day.

FAQ

Questions? Answered.

What marketplaces do you monitor?
We currently scan Craigslist, Facebook Marketplace, and estate sale listings. We're adding OfferUp, Mercari, and more soon.
How does the AI estimate resale value?
Our models analyze recently sold comparable items across eBay, Poshmark, and other resale platforms. We factor in condition, brand, category, and seasonal trends to give you an accurate estimated resale price and profit margin.
How fast are the alerts?
Pro users get alerts within minutes of a listing going live. Basic users receive batched alerts throughout the day. Speed is everything in flipping — the fastest person wins the deal.
Can I customize what categories or items I'm looking for?
Absolutely. You can set filters by category (electronics, furniture, vintage, etc.), price range, location radius, and minimum profit margin. The more specific you are, the better your alerts.
Is there a free trial?
We'll offer a 7-day free trial at launch so you can experience the power of A Co risk-free. Join the waitlist to be notified.
What if I'm new to flipping?
A Co is perfect for beginners. Our profit estimates remove the guesswork, and our alerts tell you exactly what to buy and what it's worth. Many of our users started with zero experience.
