Built for accredited India-based Investors

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.
