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.
Lockspeare's answer:
Lockspeare encrypts every photo and video on the phone itself, before it is stored. Many vault apps only put a PIN screen in front of files that stay readable on the phone: a 2022 university study of 20 Android vault apps found only 5 even tried to encrypt them. In Lockspeare, a file manager or another app that opens the vault folder sees only encrypted data, with no file names. There is no account and no server: nothing is uploaded unless you make a backup yourself, and backups stay encrypted. The full security design is published at lockspeare.com/security, including what the app cannot protect against.
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.
Lockspeare's answer:
Real encryption (AES-256-GCM) of every file, with the key protected by your PIN or pattern and the phone’s secure hardware. No account, no ads, no analytics or tracking libraries. A separate PIN or pattern from your screen lock, so someone who knows your phone’s PIN can’t open the vault. A 12-word recovery phrase if you forget your PIN, which nobody else holds. Encrypted backups to your own Google Drive or to a file, which open only with those 12 words. A decoy vault and a calculator disguise in Premium. Free for up to 50 photos and videos, with a one-time lifetime option instead of only subscriptions.
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.
Lockspeare's answer:
Android users who keep private photos, videos or documents on their phone and want them protected even if someone else uses the phone, borrows it, or copies its storage. That includes people who share a phone with family, people worried about a lost or stolen phone, and privacy-minded users who have looked at gallery “hide” features or vault apps and found that the files were still readable.
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.
Lockspeare's answer:
Lockspeare was started by Dragos Ivanov, an independent software developer from Romania with a long-standing interest in cybersecurity. He found that many popular vault apps only hide photos behind a PIN screen while the files stay readable on the phone, and he wanted a vault he would trust with his own family’s photos. So he built one that encrypts the files themselves, needs no account, and publishes its full security design so anyone can check it. It launched on Google Play in October 2026.
