As answered by people managing AuditJet and Diffyn.
AuditJet's answer

Standard tracking tools show website latency in dry, abstract milliseconds that non-technical managers ignore.AuditJet connects directly to Google's PageSpeed infrastructure and maps layout shifts, rendering delays, and script latencies into an estimated Monthly Revenue Leak using industry-referenced abandonment models. It translates technical code friction into clear, actionable business dollars.

Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
AuditJet's answer
AuditJet was founded after realizing how many engineering hours are wasted manually diagnosing front-end regressions, and how difficult it is for developers to explain the financial importance of site speed to corporate stakeholders •.I spent seven months engineering a secure, automated micro-SaaS framework from scratch as a solo builder to change the narrative around performance tracking •. By shifting the focus from "how fast a site loads" to "how much money a slow site bleeds," AuditJet turns technical debt into an immediate commercial priority
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.
