RoundOS's answer
I’m working on RoundOS because I experienced this problem myself while raising funds for another company.
The hardest part was not the pitch deck or finding investors. It was keeping all the half-warm conversations alive across email, calendar, meeting notes, LinkedIn exports, intros, spreadsheets, and random notes. A normal CRM feels like another manual system to maintain, which breaks exactly when the founder is overloaded.
RoundOS exists because fundraising is mostly a context and follow-up problem. Founders lose opportunities not only because investors say no, but because warm conversations go stale, context gets lost, and the next action is unclear.
We are building RoundOS as an AI operator for a founder-led round: it connects to the founder’s real sources, understands people, funds, intros, promises, stale threads, and next steps, then helps the founder decide what to do next and draft the right follow-up.
It is not an auto-spam tool. The goal is to help founders follow through on real conversations with better memory and less manual work.
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.
