Mobile inspection platform for multifamily operations; Due Diligence Suite validates rent rolls and surfaces deal-making insights pre-close
Strong fit for multifamily acquirers and property managers needing mobile inspection tools during due diligence — the Due Diligence Suite specifically validates rent rolls and surfaces deal-relevant condition insights pre-close, which is a genuinely useful niche capability beyond generic inspection apps. Pricing (roughly $1/unit/month for Property Suite, ~$7/unit/walk for Due Diligence) scales reasonably with portfolio size, though it's multifamily-specific and won't serve office, retail, or industrial diligence needs.
National Phase I/II ESA, PCA, zoning compliance, and seismic due diligence provider — rated #1 environmental due diligence provider in the US
Buyer: lenders, investors, and acquirers needing environmental and property condition due diligence reports -- Phase I/II ESAs, PCAs, seismic -- for an active transaction, especially where speed and defensibility matter for closing. Strength: a top-rated national provider in a fragmented, quality-variable industry, which meaningfully lowers the risk of a bad diligence report. Caveat: this is a services firm, not software -- pricing is quoted deal-by-deal, so build lead time into your due diligence timeline rather than expecting instant turnaround.
