AI integrations supporting the platform’s workflows.
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.
InstantInterview.app's answer:
Real-time AI voice interviews with quantified feedback (STAR scores, WPM, filler rate), no scripts, measurable progress.
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.

InstantInterview.app's answer:
Anyone anxious about upcoming interviews who wants realistic practice and proof they're improving.
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.
InstantInterview.app's answer:
I was looking for a tool to practise my interview skills, but everything I found was either too expensive, didn't give useful feedback, or wasn't conversational so I built it for myself, then realised others needed it too.
