Deployment and who each one targets

What each record credits

Polly: Version control plus replay reprices old scenarios against the setup live at the time. Polly: No-code deployment lets the secondary desk launch products without vendor involvement. Polly: The Loan Trading Exchange carries the platform past lock into sale and delivery. Polly: Investors include 8VC, Menlo Ventures, Khosla Ventures, Fifth Wall and First American. Loan Sifter: Published base price of $79 per month, almost unique in this category. Loan Sifter: Optimal Blue states access to more than 120 wholesale investors daily. Loan Sifter: Quotes conforming, non-conforming, government, non-QM, home equity and construction. Loan Sifter: Backed by the category’s largest pricing vendor, so investor data upkeep holds.

What each record holds against them

Polly: Publicly names few technology partners: LendingPad, Vesta, Cordless and Uplist. Polly: Investor coverage is stated as hundreds, with no specific count published. Polly: No pricing, no per-loan figure, no volume bands, no implementation range published. Polly: The line stops short of hedging: no hedge advisory or trade management module described. Loan Sifter: Built for brokers; lenders get no lock desk, margin management, best execution or hedging. Loan Sifter: Claims LOS and CRM integration but names no system at all. Loan Sifter: The loansifter.com domain redirects into Optimal Blue with no independent presence. Loan Sifter: The $79 tier covers core pricing only; upper tiers are unpublished.

Which one fits which shop

Best fit for Polly: A secondary desk that wants to reconfigure products without opening a vendor ticket. Best fit for Loan Sifter: A small broker shop that needs wholesale rate comparison without an enterprise contract.

What each entry concludes

Polly: Polly built a pricing engine, then bolted a loan trading exchange onto it. Polly: A loan is priced and locked, then sold, without leaving the platform. Polly: The differentiators are practical: configuration version control, historical replay, no-code product launches and a mobile interface officers use. Polly: Backers include 8VC, Menlo Ventures, Khosla Ventures, Fifth Wall and First American. Polly: The trade against Optimal Blue is thinner published investor coverage and fewer named integrations. Loan Sifter: LoanSifter is Optimal Blue’s broker-facing pricing engine, the rare mortgage product with a price on the page. Loan Sifter: The base subscription costs $79 a month. Loan Sifter: Optimal Blue says it reaches more than 120 wholesale investors daily and serves roughly 6,000 users. Loan Sifter: A broker who wants side-by-side wholesale comparison and no lock desk or hedging buys this without a committee. Loan Sifter: The catch is scope: this is broker quoting and comparison, not the enterprise engine.

The short answer

Polly finishes ahead on the published rubric, 4 to 3. The margin comes mostly from Functionality and depth. Same rubric, same weights, no sponsorships.
