Start engaging with your next
Portfolio Company
without picking up a tab on every slide deck in the country
Castanet is a discovery rail: structured pitches, honest filters, and messaging that opens only after you signal intent.
How it works for investors
Browse → Filter → Follow → Collaborate
Identity follows intent, not the other way around.
Step 1
Anonymous first pass
Screen structured pitches and video without broadcasting your identity to every founder in the queue.
Step 2
Follow to reveal
When you follow a startup, they see your entity and team — the start of a real two-sided thread.
Step 3
Filters that stick
Industry, stage, and geography — save combinations you run every week and get pinged when new listings match.

What Investors are saying
“I can screen twenty pitches on a Sunday morning without a single founder knowing I looked. By the time I follow, I already know if this is a real conversation or not.”
