As answered by people managing NetAPI and YieldStack.
NetAPI's answer
Security and threat intelligence teams (newly registered and compromised domains), brand protection and anti-phishing services, sales and marketing teams building lead lists, SEO and web analytics companies, and researchers who need complete lists of registered domains.
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.
NetAPI's answer
NetAPI was founded by Slava Olesik, who earlier founded zonefiles.io (he sold it in 2017; its later owners shut it down in August 2025). NetAPI is his current project in the same field: domain lists and datasets for 1,500+ TLDs, a simple API and free open datasets. It is run by CodeRockers LTD, Cyprus.
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.
NetAPI's answer
Every zone in one subscription: 380M+ active domains in 1,500+ TLDs, newly registered domains every day, enriched datasets and lists by DNS provider and registrar. We also publish free datasets: the daily NetAPI Top 1M websites ranking and compromised domain and IP lists (CC BY 4.0).
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.
NetAPI's answer
Plain CSV files and a simple API, every TLD in one plan from $49 a month, daily updates, and a founder who has worked with domain data since zonefiles.io.
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.
