4th Link engineers proprietary deal flow for real estate funds, syndicators, independent sponsors and private lenders. We source off market, qualify against your buy box, and route what survives into the stack your team already works in.
Two to three weeks. We map how deals actually reach you, instrument every stage from first touch to buy box decision, and put a number on what is being lost along the way. You leave with a written build specification and the data behind it. If you take that spec and build it somewhere else, that is a reasonable outcome.
Eight to twelve weeks, embedded with your acquisitions team. Sourcing, enrichment, scoring and routing go into the stack you already run, then get documented and handed over. Scope comes out of the audit, so there is nothing left to estimate by feel.
We hold the funnel after handover. Data spend, monitoring, scoring adjustments as your buy box moves, and one monthly report against sourced, qualified and matched counts. Thirty days notice to stop.
A separate and lower tier from the custom work above. These are systems we have already built, tested and run inside live operations. You buy one outright, we deploy it into your business within 30 days, and it stays maintained on a monthly retainer. Fixed scope and fixed price, $1,750 to $3,500 depending on the system, with maintenance from $1,150 a month.
If none of them fits how you actually source, that is what the origination audit is for.
Off market sourcing and buyer matching for real estate acquirers. Every incoming deal is scored against your buy box and your buyer list inside a minute, with the reasoning attached so an analyst can argue with the score instead of trusting it.
Origination for lenders and mortgage desks. Borrowers are classified by product, intent and timeline, then ranked and pushed to whoever is on the desk. Refinance candidates surface out of the existing book without anyone running a report.
Intake and case selection for plaintiff firms. High value matters are identified within minutes and limitation dates tracked with escalating alerts, so selection stops depending on who happened to pick up the phone.
Pipeline and cross sell for insurance agencies. Multi policy prospects are flagged as they arrive, and bundle, life and umbrella gaps surface against the book you already hold rather than sitting undetected in it.
Lead routing for home services operators. Every enquiry is answered inside fifteen minutes, emergency work is pushed to the front of the queue, and insurance jobs are flagged on arrival rather than discovered later.
Booking and retention for aesthetics clinics. Enquiries are answered inside fifteen minutes, consultations book without staff involvement, and a rebooking engine works the existing client list on a schedule.
Firms deploying across several markets who need flow that does not rest entirely on broker relationships and a shared inbox.
Deal Sourcer in production →Acquirers working without committed capital, where proprietary flow decides whether you are sitting in a process or running one.
Deal Sourcer in production →Desks that win on response time and need every borrower scored and routed before a competitor calls back.
Loan Sourcer in production →Teams carrying more markets than headcount, where the constraint is qualification capacity rather than deal volume.
Custom build →Advisors sourcing mandates and matching them to buyers, where the quality of the list is most of the service being sold.
Custom build →Legal, insurance, home services and aesthetics operators running the Sourcer systems in production today.
Four systems live →4th Link came out of a working background in law and property rather than a computer science one. That shaped the order we do things in. We had to understand how an acquisition actually gets decided before we could automate any part of it, and that sequence has held up in every engagement since.
Three years of building for US real estate firms and operators kept surfacing the same finding. Volume was almost never the constraint. What broke was everything between a deal arriving and a competent person deciding on it, and no firm we worked with had ever put a number on that gap.
We built systems to close it, then turned the strongest of them into products. Every system we ship has run inside a live operation before it goes near the next client.
Tell us how deals reach you today. We will come back with what we would build, what it would cost, and whether the numbers justify building it at all.
