As answered by people managing EquityReplay and YieldStack.

EquityReplay's answer

YieldStack's answer:
AI integrations supporting the platform’s workflows.
EquityReplay's answer
Equity Replay makes portfolio history easy to explore. Users can replay custom stock and ETF allocations, compare portfolios, and explore public portfolio snapshots based on publicly available disclosures. Allocations are applied once at the start of a selected period—there are no trades, buy-and-hold instructions, or rebalancing.
YieldStack's answer:
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
EquityReplay's answer
Equity Replay is simple, visual, and educational. Users can explore a portfolio without connecting a brokerage account, review transparent historical assumptions, adjust allocations, compare stocks or portfolios, and use AI to create an editable starting mix.
YieldStack's answer:
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
EquityReplay's answer
Equity Replay is for curious investors, beginners, educators, and anyone who wants to understand how stock and ETF allocations might have moved through different historical periods. It is designed for learning and exploration, not active trading or financial advice.
YieldStack's answer:
Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.
EquityReplay's answer
Equity Replay started with a simple question: how would a portfolio allocation have moved if it had been created in the past? The product was built to make that question easier to explore through clear charts, public portfolio snapshots, stock comparisons, and adjustable historical scenarios.
YieldStack's answer:
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
