More time where it matters.

OpenBower is a spreadsheet that does its own research. Every column is a key detail, agents dig them up, and you focus on the close.

Put an expert on every detail.

Each detail that matters gets its own agent: the decision maker, the last raise, what changed this quarter.

New rows research themselves.

Add rows by hand, webhook, or CSV, and your agents add the details the moment they land.

Get pinged when the research is ready.

No watching the sheet. When a row completes, it meets you where you work: your CRM, your sequencer or an automation. Then you say hello.

Open source and self-hostable.

Read the source.
Everything that runs your sheet is on GitHub. Read it, run it or fork it for your needs.
Bring your own model.
Any OpenAI or Anthropic compatible endpoint: a model on your laptop, your own deployment, or the vendor itself.
Your data stays yours.
Self-host it and your agents run in your environment. The only traffic out is the vendor calls you configured.
No credits.
You get as much research as your compute allows, at the vendor's price.

Free to prove. Pay to scale.

Getting your idea in front of potential users should not be pay to play. Self-host the whole thing free forever, or just while you prove it. The only costs are your vendors’, and they grow when you do.
