BallIQ.app's answer
Every answer is explained. Most football quizzes just say "wrong" and move on — Ball IQ gives you a fact-checked hint explaining why, so playing feels like learning rather than being tested. All 4,000+ questions are hand-curated, not scraped.
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.
BallIQ.app's answer
Depth. 4,000+ hand-written, fact-checked questions spanning the World Cup, Premier League, Champions League, La Liga, Serie A and the Bundesliga, plus 20+ club packs from Arsenal to Galatasaray. Free, no sign-up to start playing, and no ads in the app.
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.
BallIQ.app's answer
Football fans who like the details — people who argue about records and remember old squads. Split between daily-puzzle players (Footle, Daily 7) and friends playing head-to-head in live multiplayer.
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.
BallIQ.app's answer
It started from a frustration: almost every football quiz online is shallow, and when you get one wrong it just says "wrong" and moves on. Ball IQ explains every answer. It's an independent project, built and maintained in Norway.
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.
