Tools built for the portfolio.
This is the working software behind the portfolio. Some of it Mosser owns outright and nobody else touches. Some of it is an LFI product that Mosser runs in a dedicated environment with no other clients in it. Either way, it is built around the same idea: the asset management team should spend its hours on decisions, not on assembling the information needed to make them.
Most of this runs on first-party Mosser data plus public records. Some products also rely on licensed third-party feeds, and those sources are called out in the app details.
Access, feature requests, and anything that looks wrong go to Justin.
Every SF multifamily competitor listing, refreshed twice a day — rents, concessions, days on market, removals.
Scrapes eleven SF competitor operators across AppFolio, Yardi RentCafe, and custom platforms, plus a Craigslist SF filter. Full change history on every listing. Anonymous Craigslist posts are attributed back to operators through an editable fingerprint dictionary.
AI-enabled asset management. Scales AUM by focusing asset managers on what creates value and what flags risk.
The LFI flagship, running in a dedicated Mosser-only environment. Ingests M365, Granola, Smartsheet, Teams, and Brickston Cloud SQL event triggers, then extracts tasks, commitments, decisions, and entities resolved to property and resident.
Watch any San Francisco parcel and get told when DBI files a complaint or a notice of violation against it.
A standing watch on SF Open Data. Pick the parcels you care about — owned, targeted, or next door — and Watch monitors DBI building complaints and NOVs against them and emails when something lands. Any parcel citywide, not just portfolio addresses.
Deal sourcing workspace — find and screen SF multifamily acquisition candidates before they hit a broker's list.
Pipeline-first sourcing across the SF multifamily universe, keyed on APN. Pulls DataSF civic signals plus PropertyRadar distress and ownership data, scores candidates, and gives each one a dossier view. Deals graduate into the transaction registry once they go live.
The operating system for the in-house repair and maintenance business — clients, jobs, financials, and whether the plan is being hit.
Back9 Trades is Mosser's own R&M company, and this is what runs it. Accounts and prospects on one side, Jobber work-order operations on the other, and the financials tying them together. KPIs map line by line to the business plan so a variance shows up at the operating level, weeks before it reaches the P&L.
