BidWiser was born from a simple observation: even experienced eBay buyers sometimes get burned. Despite years of shopping on eBay, you can still miss red flags in a listing, overlook seller warning signs, or fall for a deal that's too good to be true.
We built BidWiser to be the extra set of eyes every buyer needs. Using AI to analyze dozens of data points, BidWiser helps you make more informed purchasing decisions before you commit to a bid.
BidWiser is made by BidSlammer, one of the original eBay sniping services. When eBay opened their API to developers in 1999, we were among the first to build tools for auction bidders.
For over two decades, we've helped millions of users win auctions by placing bids at the last second. BidWiser is our newest tool, applying artificial intelligence to help buyers research listings before they bid.
BidSlammer is run by a small, dedicated team of developers and eBay enthusiasts. We're committed to building tools that make eBay buying safer and more fun.
