Froddy is designed for teams that need more control before invoice payments or financial operations are executed. - It does not replace the existing bank, processor, or payment system. - It works on top of the current workflow via API/webhook. - It helps teams decide whether an operation should be allowed, held, rejected, or escalated before execution. - It can start in shadow mode, so teams can validate decision quality without affecting real payments.

Froddy's answer
Froddy is built for teams that manage or automate financial operations. - Fintech companies - Payment operations teams - Finance and treasury teams - B2B SaaS platforms handling invoices, payouts, approvals, or automated financial workflows The first use cases are invoice payment decisioning, procurement and spend workflows, and payment operations that need an extra control layer before execution.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Froddy's answer
Froddy was created around a simple problem: as automation and AI move closer to financial execution, teams need a separate decision point before money actually moves. - A process may be ready to pay an invoice. - The counterparty may be new. - The amount may be unusual. - Payment details may have changed. Froddy exists to provide that final pre-payment decision layer.
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.
