val8's answer:

val8 simulates a live, multi-round deliberation among 45 distinct AI personas spanning investors, domain experts, and target users. Unlike generic AI chatbots that default to agreeable praise, val8 uses skeptic preservation with dedicated "roaster" and "ragebait" voices that stress-test hidden assumptions and debate each other before delivering an actionable consensus score.

Why should a person choose your product over its competitors?

Diffyn's answer

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

val8's answer:

Traditional idea validation requires weeks of waiting on surveys, hiring expensive consulting firms, or relying on friends who are too polite to be honest. Single-prompt AI tools give superficial summaries. val8 provides deep, multi-perspective stakeholder debates and brutal feedback in minutes, with pay-as-you-go pricing starting at just ₹49 (~$0.51).

Which are the primary technologies used for building your product?

React, Next.js, POSTGRESQL

val8's answer:

Solo founders, indie hackers, early-stage startup builders, product managers, and entrepreneurs who want to validate their business concepts, identify blind spots, and assess real willingness to pay before spending months coding.

What's the story behind your product?

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.

val8's answer:

Like most founders, we spent months building projects after friends told us the idea was 'great', only to launch to complete silence. Realizing that polite feedback kills startups, we engineered val8 to recreate the room full of skeptical VCs, strict domain experts, and picky customers that every founder needs before writing a single line of code.

Who are some of the biggest customers of your product?

val8's answer:

  • Early-stage tech startup founders
  • Indie hackers and solo makers
  • Product managers validating new feature concepts
  • Entrepreneurship students and incubator builders
