I made WatchDog because I was tired of the little wave of panic every time I had to leave my MacBook on a cafe table to grab a coffee or run to the restroom. Here is how it works. You arm it before you step away. If someone touches or moves your Mac, it sounds a loud alarm and pings your iPhone...

WatchDogApp.de's answer
WatchDog is one of the few Mac anti-theft tools that reacts in the moment instead of after the fact. Most options only help you locate your Mac once it is already gone. WatchDog sounds a loud alarm and pings your iPhone the instant someone touches or moves your MacBook, locks the screen, and resists quick shutdown attempts, so a thief gets noticed before they can walk away.
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.
WatchDogApp.de's answer
Trackers like Find My and Prey are recovery tools that help you chase your Mac after it is stolen. WatchDog is a deterrent. It makes a scene the second someone reaches for your laptop, which is what actually stops a grab in a busy cafe or library. You arm it with a tap, it works offline over Bluetooth, and it never touches your files.
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.
WatchDogApp.de's answer
People who work on a MacBook in public. Students in libraries, remote workers and freelancers in cafes, and digital nomads in coworking spaces. Anyone who has to leave their laptop on a table to grab a coffee or use the restroom and wants to step away without worrying it gets taken.
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.
WatchDogApp.de's answer
I work out of cafes and coworking spaces, and I could never relax when I had to leave my MacBook to grab a coffee or use the restroom. Find My only helps after your Mac is already gone. I wanted something that reacts in the moment, so I built WatchDog. You arm it, step away, and if anyone touches your Mac it sets off a loud alarm and pings your phone right away.
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.
