Questions & Answers

As answered by people managing Doorstep and Diffyn.

What makes your product unique?

Doorstep's answer

Doorstep is the only app that tracks your home buying power daily instead of giving you a one-time calculation. While calculators show a static number, we update automatically as mortgage rates change and your finances improve. We also pre-filter every home listing to what you can actually afford, so you never fall in love with something out of reach. And when you're ready for an agent, you initiate the connection and share your profile with them. No lead farms selling your info the moment you enter your email.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

Why should a person choose your product over its competitors?

Doorstep's answer

Zillow shows you homes without knowing your finances. Redfin and Trulia do the same. Mint tracks your money but has no connection to real estate. Doorstep bridges the gap by combining real-time financial tracking with personalized home browsing. You get a clear readiness score, see exactly what's holding you back, and follow a step-by-step plan to close the gap. It's free for buyers, requires no credit check, and takes 2 minutes to set up.

Diffyn's answer:

Diffyn is the platform that specializes on both change management and multi-model analysis.

Which are the primary technologies used for building your product?

Doorstep's answer

React Native with Expo for iOS and Android apps React and TypeScript for the web platform Node.js and Express for the backend API MongoDB for data storage Plaid for optional bank account integration

Diffyn's answer:

React, Next.js, POSTGRESQL

How would you describe the primary audience of your product?

Doorstep's answer

First-time homebuyers who are 6 to 18 months away from purchasing. Renters wondering if they can afford to buy. Young professionals tired of browsing homes they'll never own. Anyone who wants clarity on their real buying power without talking to a lender or getting bombarded with sales calls.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

What's the story behind your product?

Doorstep's answer

We watched friends and family fall in love with homes they couldn't afford only to find out months later when a lender broke the news. The tools that exist either ignore your finances (Zillow) or ignore real estate (Mint). We built Doorstep to answer one question clearly: what can I actually afford today? And we update that answer every single day. We were founded by three Denver area natives, two of which are military veterans.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

Who are some of the biggest customers of your product?

Doorstep's answer

We're launching in January 2026 and currently building our early access waitlist. Our target users are first-time homebuyers across the United States, starting with Colorado where we are developing relationships with brokers. The app will launch nationwide, however.
