I’ll start.

I’m building Round Funded, a fundraising platform for founders raising their first rounds.

We help founders find active, vetted investors, get matched based on their stage, and manage investor outreach without spending weeks digging through random databases.

The hardest part we’re solving right now: making fundraising feel less like guessing who might invest and more like knowing who is actually relevant.

Your turn. Drop:

  • What you’re building

  • Who it’s for

  • The hardest problem you’re solving right now

Would genuinely love to see what everyone here is working on.

I'm building Heym, a self-hosted platform for building and running agentic AI workflows.

It's for teams and developers who want to orchestrate multi-agent systems (RAG, MCP tools, human approval checkpoints) without gluing five different tools together, and without handing their data to someone else's infrastructure.

The hardest problem we're solving right now: making long-running agent workflows actually observable and recoverable, not just fast. Full traces on every LLM call, automatic context compression before agents drift, and persisted checkpoints so a human review at 2am doesn't mean the run is lost.

We actually relaunched on Product Hunt today:

I'm building Framewrite () to turn a video into a real document, with the actual slides/diagrams from the video. The idea is to make search and archival easy.

previously I build prompt management tool and AI skills marketplace.
