Prep Sarthi is a spoken mock interview that runs in your browser, including on a phone. It reads the CV you upload and interviews you about your own projects rather than from a generic question bank, so the questions are the ones you will actually be asked. It presses for more when an answer is...

  • Unverified: possible specialization
    I can't browse yieldstack.ai and have no reliable information about this product, so I can't confirm its features. If it is a focused tool in the yield or optimization space, a narrow focus can mean a simpler, more purpose-built experience than a general-purpose platform. Check the site to confirm what it does.
  • Unverified: possible AI-driven automation
    The .ai domain suggests AI or automation features, which could save time on analysis or decisions if they work as advertised. This is an inference from the domain name, not a confirmed feature. Verify it against the product's documentation or demo.

Overall verdict

  • I don't have verified information about YieldStack (yieldstack.ai) in my training data, so I can't confirm claims about its features, pricing, reliability, or reputation. It may be a newer, niche, or rebranded product that isn't well-documented in publicly available sources I was trained on.

Why this product is good

  • Unable to verify specific features or capabilities without independent research
  • No confirmed user reviews, ratings, or reputation data available to me
  • Cannot validate security, compliance, or business legitimacy claims
  • Recommend checking the site directly, looking for third-party reviews (G2, Trustpilot, Reddit), verifying company registration, and testing any free trial before committing

Recommended for

  • Users who conduct their own due diligence before adopting new SaaS tools
  • Those comfortable trying early-stage or emerging products with appropriate caution
  • Not recommended for critical business decisions without independent verification of claims

Questions & Answers

As answered by people managing Prep Sarthi and YieldStack.

Who are some of the biggest customers of your product?

YieldStack's answer:

The largest CRE Lenders in the USA

Which are the primary technologies used for building your product?

Prep Sarthi's answer

Google Gemini Live for the spoken interview, over a WebSocket, with the microphone captured and resampled in the browser through an AudioWorklet. The site is static and the back end is a Cloudflare Worker with a D1 database. Your CV is read in your own browser and goes only to Google, on your own key.

YieldStack's answer:

AI integrations supporting the platform’s workflows.

What makes your product unique?

Prep Sarthi's answer

It interviews you from your own CV rather than from a question bank. It reads the resume you upload and asks about the projects on it, so the questions are the ones only you can be asked, and it asks again when an answer is thin. The report is measured rather than guessed: the pause before you started speaking, your words per minute and your filler words all come from your microphone.

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.

Why should a person choose your product over its competitors?

Prep Sarthi's answer

Most tools cap how much you can practise, because a spoken interview costs them money every minute. Prep Sarthi runs on your own free Google Gemini key, so a pass buys unlimited practice instead of a set number of sessions. It also interviews in Hindi and Hinglish, which matters in India, where interviewers often switch language mid-question. And you can try it for twenty minutes without an account or a card.

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.

How would you describe the primary audience of your product?

Prep Sarthi's answer

Indian graduates and early-career candidates preparing for the large service companies, where the panel interviews your resume and the round is short. It also suits anyone who has written a strong CV but has never said it out loud.

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.

What's the story behind your product?

Prep Sarthi's answer

It came out of Interview Sarthi, a Windows app that helps during a live online interview. People kept asking for something to use before the interview rather than during it, and that is a different product, so it was built as one. It is made by one person in Delhi.

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.
