LoadCairn's answer:
Not available at this thime.
YieldStack's answer
AI integrations supporting the platform’s workflows.
LoadCairn's answer:
A web app built on the Polsia platform. It installs on phone or laptop as a progressive web app (PWA) and works offline.
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.
LoadCairn's answer:
Every calculator shows its formula, inputs and assumptions, with references to ASHRAE and NIST. Engineers can check the math instead of trusting a vendor tool that hides it.
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.
LoadCairn's answer:
Vendor calculators from APC, Eaton and Vertiv are tied to their own products and don't show their work. LoadCairn is vendor-neutral, free with no account, and covers power, cooling and facility metrics in one place. It also works offline in data halls with no signal.
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.
LoadCairn's answer:
Critical facility engineers, data center technicians, facility managers, MEP consultants, data center project teams and students.
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.
LoadCairn's answer:
I've worked in data centers for 20 years. Most sizing still happens in old spreadsheets or vendor tools that won't show the math. I built LoadCairn so engineers have quick, transparent estimates they can defend in a design review.
