Raziel leverages AI and machine learning for data ingestion, insights, trend analysis, and automation. It uses modern web technologies for its responsive dashboard and real-time features, along with robust integration capabilities supporting thousands of platforms and APIs. The infrastructure prioritizes security, scalability, and performance with enterprise-grade standards.
YieldStack's answer
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage.

Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
Raziel's answer:
Raziel is a unified portfolio management platform built specifically for alternative assets. It brings together startup investments, real estate, crypto, and public equities into one central dashboard. Key differentiators include AI-powered data ingestion and insights, over 12,000 integrations with automatic handling for everything else, real-time tracking, advanced visualizations, and automated alerts. The platform emphasizes security (working toward SOC 2 compliance), scalability for any portfolio size, and a clean interface that eliminates the need for spreadsheets or multiple tools.
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.
Raziel's answer:
Raziel stands out by focusing exclusively on alternative and diversified assets in a single, intuitive platform rather than forcing users to piece together separate tools. It delivers AI-driven insights for trends, risks, and opportunities, seamless data import across thousands of sources, and comprehensive reporting. Users gain clearer visibility, reduced administrative work, and smarter decision-making tools. The combination of real-time updates, strong security measures, and investor-friendly design makes it more efficient and powerful for managing complex portfolios.

Raziel's answer:
Raziel primarily serves angel investors, venture capitalists, family offices, and individual or institutional investors who manage diverse alternative assets. This includes people actively involved in startup investing, real estate, crypto, and traditional equities who want a consolidated view without fragmented tools. It appeals to both experienced investors seeking advanced analytics and those looking for an easier way to track and optimize growing portfolios.
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.
Raziel's answer:
Raziel was founded in 2022 in Los Angeles by Jordan Rothstein (CEO). The company emerged from the founders' own frustrations with managing investments across scattered platforms, spreadsheets, and tools. They built Raziel to solve this pain point by creating a modern, AI-powered central hub for all alternative assets. The platform officially launched in early 2025 with a focus on simplifying portfolio management for smarter investing.
