YieldStack's answer
AI integrations supporting the platform’s workflows.
SecuryBlack's answer:
React (frontend), PostgreSQL, Docker, Rust (telemetry agent OxiPulse via gRPC/OTLP), self-hosted on Hetzner.
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.
SecuryBlack's answer:
SecuryBlack combines three tools into one: continuous email breach monitoring, uptime monitoring, and heartbeat checks for backup verification. Most tools do one of these. SecuryBlack does all three in a single dashboard, so homelabbers and developers stop juggling separate subscriptions.
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.
SecuryBlack's answer:
Uptime Kuma monitors your services but doesn't check breaches. HIBP checks breaches but not uptime. Healthchecks.io verifies cron jobs but nothing else. SecuryBlack replaces all three with one unified dashboard and one subscription at €19/month — or free.
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.
SecuryBlack's answer:
Homelabbers, sysadmins, and developers who self-host services, run automated backups, and want to know immediately if something breaks or their email appears in a data breach. Technical users tired of managing multiple monitoring tools separately.
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.
SecuryBlack's answer:
Built out of personal frustration with tool fragmentation. Running a homelab meant paying for and managing Uptime Kuma, HIBP, and Healthchecks separately. SecuryBlack started as a side project to consolidate everything into one place, and grew into a product for anyone running their own stack.
