A workspace for long-cycle thinking.

Sources, synthesis, and memos in one loop. AI isn't a feature here—it's a workflow layer on top of your research. The goal is faster conviction with fewer blind spots.

Keep sources, synthesis, and the memo in one loop. Less “who said that?” more “here’s the source.”Fifteen is an agentic workspace built for investors and research-heavy teams. Capture sources, draft memos with context-aware agents, and keep decisions traceable from first signal to IC.
A workspace for long-cycle thinking.
Your team’s research shouldn’t reset every deal. Fifteen turns past work into a reusable edge.

Research that remembers, decisions with provenance.

Keep sources, synthesis, and the memo in one loop. Less “who said that?” more “here’s the source.”_

From signal to memo, without losing context._

Fifteen is an agentic workspace built for investors and research-heavy teams. Capture sources, draft memos with context-aware agents, and keep decisions traceable from first signal to IC.

Memos shouldn’t start from a blank page. Fifteen keeps provenance intact and drafting grounded in your sources.

Stop tab-hoarding. Start compounding.

Most research workflows fail when context breaks. Fifteen keeps the loop closed—capture → synthesize → draft → decide.
