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.
Pawgo.fr's answer:
No one else does what PawGo does. Here's why: pet travel rules are scattered across hundreds of airline PDFs, government websites, and vet forums — all in different formats, different languages, and constantly changing. Today people spend hours or days piecing together info from 10+ sources, and still miss things. One wrong document = denied boarding or quarantine.
What exists today:
Government websites (raw regulation text, hard to parse) Pet relocation companies ($500-3,000, manual process, takes weeks) Blog posts (generic, outdated within months) Facebook groups (anecdotal, contradictory advice) What PawGo does differently:
Automated, not manual. An AI agent crawls and verifies the actual sources 24/7. No human copy-pasting from PDFs. Personalized, not generic. Your breed + your airline + your destination = your exact checklist. A French Bulldog on Air France to Japan gets a completely different plan than a Labrador on Delta to Spain. Deadline-aware. It calculates backwards from your departure: "book vet appointment by May 3, get USDA endorsement by May 7, freeze water bowl May 9." Not just "get a health certificate." Cross-referenced. It checks airline rules AND country rules AND breed restrictions simultaneously. No other tool connects all three. Free. Pet relocation services charge hundreds. PawGo is free, no signup.

Pawgo.fr's answer:
I rescued stray dogs in Morocco. Not one — several, over multiple trips. Each time I had to figure out how to get them on a plane to Paris, and each time it was a mess.
Morocco is a high-risk rabies country, which means the rules are brutal: titer tests with 3-month waiting periods, specific vaccination sequences, health certificates that expire in 10 days, government endorsements that take a week. Every airline had different carrier rules. Every vet gave me different advice. I spent days on the phone with Air France, hours on Moroccan government websites in Arabic, and made multiple trips to the DDPP office for document stamps.
I got it wrong more than once. Missed a vaccination deadline by two days — had to rebook the flight and wait another month. Showed up at CDG with a carrier that was 2cm too tall — almost didn't board. Had a health certificate rejected because the microchip number was written in the wrong field.
After the third rescue, I realized I was rebuilding the same research from scratch every time. And if it was this hard for me — someone who'd already done it — imagine a first-time pet traveler trying to figure this out.
So I built PawGo. Everything I learned the hard way, automated. The tool I wish I'd had the first time I walked into Casablanca airport with a scared dog in a crate and a folder full of papers, hoping I hadn't missed anything.
