As answered by people managing NordTell and YieldStack.
NordTell's answer
Our biggest and first is: https://klinikagent.dk and https://nordbooq.com
YieldStack's answer:
The largest CRE Lenders in the USA
NordTell's answer
Here's our techstack: - Python (Flask) and PostgreSQL with pgvector on the backend - React and TypeScript on the frontend - LiveKit for real-time audio - Speech and language models from OpenAI, Google, ElevenLabs and Cartesia, chosen per agent
YieldStack's answer:
AI integrations supporting the platform’s workflows.
NordTell's answer
Three things you rarely get together: It is honest on the phone. The agent always says it is an AI, and it never tells a caller "you're booked" before the calendar has confirmed it. It is properly multilingual. One agent can speak several languages in the same call, each with its own native voice. About 40 languages, including Danish, Swedish and Norwegian and with different voices/voice models (no other platform has this feature - hence why we have created it) It is European. Built in Copenhagen, hosted in the EU, and every AI model is named with its provider, so you know where your calls go.
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.
NordTell's answer
Because the price list is the whole story. You pay per minute of conversation, from EUR 29 a month. Every plan has every feature, with no per-seat fees, no per-agent fees and no setup fee.
You can also build and test an agent for free in your browser, using your microphone, before you connect a phone number. And when a caller needs a person, the agent briefs your colleague first and then puts the call through, so nobody has to repeat themselves.
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.
NordTell's answer
Small and mid-sized businesses whose phone rings while their hands are full: clinics, trades, salons, property managers and service companies, mostly in the Nordics and Germany.
The second group is agencies. They build phone agents for their own clients and resell NordTell under their own brand and domain.
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.
NordTell's answer
NordTell is built in Copenhagen by Interactive Made ApS.
We created Nortel because we were basically tired of the lack of flexibility, features, and speed that are offered by our competitors. Sometimes you can get the flexibility, but you have to pay a ton of money for it. Sometimes you get the speed, but you lack a lot of features, and this frustrated us so much that we chose to embark on the journey to create the first Nordic platform that has all the flexibility that Retail AI has, all the features that Famulor has, and the speed that nobody has - at best possible price.
So we built the phone agent we wanted ourselves: one that speaks Nordic languages well, keeps its data in the EU, shows its prices openly and never pretends to be human.
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.
