As answered by people managing YieldStack and VettBase.
YieldStack's answer
The largest CRE Lenders in the USA
VettBase's answer:
VettBase is currently in early public beta, so there are no public customer logos to list yet. The product is being tested for small SaaS teams, AI tool builders, Shopify app developers, WordPress plugin makers, independent B2B builders, and agencies that need to answer buyer security questionnaires faster.
YieldStack's answer
AI integrations supporting the platform’s workflows.
VettBase's answer:
VettBase is built with Next.js, React, TypeScript, Supabase, OpenAI API, Stripe, and Vercel. Supabase is used for authentication and cloud-saved workspace data, OpenAI is used for AI-assisted answer drafting, Stripe is used for billing infrastructure, and Vercel is used for deployment.
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.
VettBase's answer:
VettBase is built specifically for small B2B software teams that need to answer buyer security questionnaires without using a heavy compliance platform too early. It combines company facts, AI-assisted draft answers, a reusable answer bank, missing-information checks, and simple exports in one workspace. The focus is practical security questionnaire drafting and answer organization, not pretending to be SOC 2 certification or legal advice.
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.
VettBase's answer:
VettBase is lighter and more direct than large compliance or trust-center platforms. It is made for small SaaS teams, AI tool builders, Shopify app developers, WordPress plugin makers, and agencies that need to answer repeated buyer security questions faster. Instead of forcing a full enterprise compliance workflow, VettBase helps teams save reviewed answers, reuse approved wording, generate drafts from company information, and flag missing details before sending unsupported claims.
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.
VettBase's answer:
VettBase is for small B2B software teams that sell products or services to businesses and need to answer buyer security questionnaires. The main audience includes SaaS founders, AI tool builders, Shopify app developers, WordPress plugin makers, independent B2B builders, and agencies that need a reusable place for security answers before they have a full compliance department.
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.
VettBase's answer:
VettBase was created around a common but overlooked B2B SaaS problem: buyer security questionnaires. Small teams often answer the same questions about hosting, encryption, subprocessors, backups, AI usage, access control, deletion, incident response, and policies from scattered documents or old messages. VettBase was built to make that workflow calmer and more consistent by helping teams keep company facts, draft answers, save reviewed wording, and reuse approved responses.
