InternationalCall's answer
Python, Django, Twilio, Stripe, WebRTC
YieldStack's answer:
AI integrations supporting the platform’s workflows.
InternationalCall's answer
No apps to install, no subscriptions, no contracts. Just add credits and call any phone number worldwide directly from your browser. The person you're calling doesn't need to download anything, it works like a regular phone call
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.
InternationalCall's answer
Unlike Skype or WhatsApp, the person you're calling doesn't need an app or internet connection. Unlike calling cards, there are no hidden fees or connection charges. Unlike carrier plans, there's no monthly commitment, pay only for the minutes you actually use, and your credits never expire.
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.
InternationalCall's answer
Expats who regularly call family back home. Travelers who need to make calls abroad without expensive roaming charges. Remote workers and small business owners with international clients or team members.
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.
InternationalCall's answer
Built out of frustration with expensive roaming charges and complicated VoIP apps. Calling family abroad shouldn't require everyone to download the same app or cost a fortune. InternationalCall keeps it simple, just dial and talk.
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.
InternationalCall's answer
We're a new product focused on individual users and families who make international calls. We're not enterprise-focused, we built this for regular people who want simple, affordable calling.
