As answered by people managing YieldStack and Trayzero.app.
YieldStack's answer
The largest CRE Lenders in the USA
Trayzero.app's answer:
Trayzero is a free personal productivity app with no user accounts — so there are no named enterprise customers or B2B contracts.
The users are individuals: knowledge workers, students, developers, and GTD practitioners who want a private, local-first task system. Because no account is required and no data is collected, we don't have visibility into who uses the app beyond app store installs.
YieldStack's answer
AI integrations supporting the platform’s workflows.
Trayzero.app's answer:
Trayzero is a native mobile app built for Android and iOS. Key technologies:
There is no backend server, no cloud sync infrastructure, and no third-party analytics SDK — by design. The simplicity of the stack is intentional: fewer moving parts means fewer ways for your data to leave your device.
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.
Trayzero.app's answer:
Trayzero is the only GTD app that delivers the full Getting Things Done method on both Android and iOS — completely free, with no account and no cloud sync.
Most GTD apps make you choose between fidelity and privacy. Trayzero gives you both:
The closest local-first GTD competitor charges $99. Trayzero is free.
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.
Trayzero.app's answer:
Choose Trayzero if any of these matter to you:
vs. Todoist / TickTick — Those are cloud-synced task lists with GTD sprinkled on. Trayzero follows the full GTD method strictly, and your data never leaves your device.
vs. Things 3 / OmniFocus — Both are Apple-only and cost $50–$100+. Trayzero runs on Android and iOS, and it's free.
vs. Everdo — The closest comparison: local-first, strict GTD. But Everdo charges $99 for the mobile app. Trayzero is free and open source.
The short version: - You want real GTD, not a to-do list - You don't want your tasks in someone else's cloud - You don't want to pay for it - You use Android, iOS, or both
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.
Trayzero.app's answer:
Trayzero is built for knowledge workers and individuals who want to use GTD properly — not a simplified version of it.
The primary audience:
Trayzero works best for individuals managing their own work, projects, and commitments — it is not an enterprise or team tool.
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.
Trayzero.app's answer:
Trayzero started from a simple frustration: the best GTD apps were either locked to Apple devices, cost $80–$100, or weren't really GTD — they were generic task managers wearing a GTD label.
After searching for an app that faithfully implemented David Allen's full five-step method on Android, the answer kept coming back empty. So Trayzero was built to fill that gap.
The goal was straightforward: implement GTD properly, make it available on both Android and iOS, keep the data on the device, and charge nothing. No subscriptions, no accounts, no cloud servers holding your tasks.
Trayzero is an independent app — not affiliated with the David Allen Company — built by a solo developer who wanted a serious GTD system without the usual trade-offs. The source code is open, so anyone can verify the privacy claims or contribute.
