OUR ORIGIN
A System Born From the Field — Not a Boardroom
Sentinel was founded by a Silicon Valley engineering veteran who became a licensed California contractor and multifamily investor.
That combination revealed a truth most lenders already know:
Borrowers don’t lose deals because of interest rates — they lose deals because their files lack clarity, discipline, and contractor verified logic.
Sentinel was built to fix that.
OUR PHILOSOPHY
Lender Aligned. Contractor Verified. System Driven.
We believe:
• Underwriting should be repeatable, not subjective
• Contractor data should be verified, not assumed
• Borrower files should be clean, not chaotic
• Risk should be filtered, not discovered late
• Deals should move faster, not get stuck in review
Sentinel exists to bring discipline, clarity, and operational credibility to every deal that passes through our system.
WHAT MAKES SENTINEL DIFFERENT
We Don’t Broker Deals — We Engineer Them
Most brokers push volume.
Sentinel pushes quality.
We operate like an extension of a lender’s underwriting team:
• Contractor verified scopes and timelines
• Realistic cost to complete logic
• Market aligned comps
• DSCR, LTC, ARV, and exit modeling
• A/B/C risk tier classification
• Clean, lender ready files
This is not marketing.
This is risk filtration.
