FindersKeepers.app VS YieldStack

YieldStack's answer:

The largest CRE Lenders in the USA

FindersKeepers.app's answer

Next.js on the App Router, with React and Tailwind on the front end, deployed on Vercel.

Listing and pricing data comes from eBay's APIs. A scheduled job re-checks every saved search and watched item on a fixed hourly cadence, records watched-item prices every six hours, and computes deal scores against the comparable active listings in the same search. Alerts go out over email and web push.

YieldStack's answer:

AI integrations supporting the platform’s workflows.

FindersKeepers.app's answer

Two things eBay does not give you, in one place.

Alerts run on a fixed hourly schedule instead of eBay's own batching, so you hear about a price drop or a new match while it is still actionable. And every item you watch gets a price history, recorded every six hours from the day you add it, which eBay listing pages do not offer at all.

On top of that, listings are scored against similar active listings in the same search, so you see whether an asking price is actually good instead of just seeing a number. Twenty percent or more below the average is flagged as a hot deal.

All of it is free, with no paid tier, and you can search eBay through FindersKeepers without an account or an eBay login.

YieldStack's answer:

YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.

FindersKeepers.app's answer

Because it covers the whole job for free, and it tells you when another tool is the better pick.

Most eBay tools do one piece well. WatchCount reads real sold data. Madealert pushes alerts within seconds of a listing appearing. eBay's own saved searches are already built into the site you are shopping on. FindersKeepers puts hourly alerts, price history, deal scoring, auction countdowns, saved searches, seller watchlists, image search, and collection tracking together at no cost, on US and international eBay marketplaces.

We also publish comparison pages against nine other tools, written in-house, including the parts where the other tool wins. Madealert beats our hourly check on speed and the page says so. That is the same standard the blog holds: every factual claim about how eBay works links to the eBay help page it came from.

YieldStack's answer:

YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.

FindersKeepers.app's answer

Collectors and bargain hunters who shop eBay regularly. Trading cards, watches, coins, video games, vinyl, retired LEGO sets, Funko Pops, vintage clothing, ex-corporate hardware.

These are buyers, not sellers. They already have a mental want list and a rough sense of what a fair price looks like, and they are tired of refreshing the same search, missing an auction by twenty minutes, or finding out later that the listing they passed on was actually underpriced.

The common thread is caring about paying the right price for one specific thing, rather than browsing deals in general.

YieldStack's answer:

Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.

YieldStack's answer:

Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
