Why should a person choose your product over its competitors?

Most document tracking tools (like DocSend or PandaDoc) charge steep monthly enterprise subscriptions ($65+/user/mo) and bundle complex features that small teams don't need.

What's the story behind your product?

TrackDoc.site's answer

TrackDoc was born out of frustration with the 'proposal black hole'—spending days crafting detailed business proposals, emailing them as static PDF attachments, and waiting in total silence. We wanted to know if prospects actually read the pricing, which slides they skipped, and when they were reviewing the document. Existing tools felt too complex and overpriced, so we built TrackDoc to give every sales professional a clear, data-driven advantage.

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.

TrackDoc.site's answer

  • Boutique B2B Digital Agencies
  • Independent Software & Design Freelancers
