YieldStack's answer
AI integrations supporting the platform’s workflows.
RigPolice's answer:
RigPolice is a static-first site built with Astro and Svelte, styled with Tailwind CSS, and hosted on Cloudflare. The tests use standard browser APIs, so they run on any modern device with no plugins.
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.
RigPolice's answer:
RigPolice puts every gaming-gear test in one place. Most sites cover a single check, like a mouse double-click test or a dead pixel scan. RigPolice bundles mouse, keyboard, monitor, audio, network, and mobile sensor tests under one roof, all in the browser, all free, with no sign-up. You can also embed any test on your own site with one line of code.
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.
RigPolice's answer:
It is free with no account, no install, and no paywall. Every test runs locally in your browser, so nothing is uploaded. Results are shareable by link, the tools load fast, and one site covers gear that competitors split across many separate pages. Need a tool on your own page? Each one ships with a free embed.
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.
RigPolice's answer:
Gamers tuning their setup, shoppers checking used hardware before they buy, and anyone who wants a quick health check on a mouse, keyboard, monitor, or phone. No technical background needed.
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.
RigPolice's answer:
RigPolice started from a simple frustration: testing a new or used device meant hopping between a dozen single-purpose sites, each loaded with ads and sign-up walls. The goal was one clean, fast place to run every common hardware check for free, in the browser, with nothing to install.
