Questions & Answers

As answered by people managing RetryFi and Diffyn.

What makes your product unique?

RetryFi's answer

RetryFi is opinionated about why a payment failed. It reads the Stripe decline code and reacts: soft declines (insufficient funds, generic) get smart retries, while hard declines (expired or lost card) skip retries and go straight to a branded "fix your card" email with a one-click update link. It runs alongside Stripe's own retries as a single branded sequence — no generic Stripe notices, no platform price tag, and no percentage cut of what you recover.

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?

RetryFi's answer

Most failed-payment tools fire generic retries or take a percentage of recovered revenue. RetryFi does neither. You get a branded, decline-code-aware sequence sent under your own name and logo, a recovery dashboard, and a 90-day historical scan of what you've already lost — set up in seconds with Stripe OAuth, no code. It's built and priced for indie SaaS: free up to 10 recoveries a month, flat $29 and $79 tiers above that, never a cut of your revenue.

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?

RetryFi's answer

Next.js (React 19, TypeScript) front and back, Supabase (Postgres) for data and auth, the Stripe API via Connect/OAuth for billing, Inngest for the durable retry and dunning workflows, Resend + React Email for the branded emails, Recharts for the dashboard, and Tailwind CSS for the UI.

Diffyn's answer:

React, Next.js, POSTGRESQL

How would you describe the primary audience of your product?

RetryFi's answer

Indie and bootstrapped SaaS founders running subscriptions on Stripe — usually solo or small teams losing recurring revenue to failed payments, who don't want an enterprise dunning platform or a tool that skims a percentage of what it recovers.

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?

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.
