Built for accredited India-based Investors
Castanet is a discovery rail: structured pitches, honest filters, and messaging that opens only after you signal intent.
Browse → Filter → Follow → Collaborate
Identity follows intent, not the other way around.
Step 1
Screen structured pitches and video without broadcasting your identity to every founder in the queue.
Step 2
When you follow a startup, they see your entity and team — the start of a real two-sided thread.
Step 3
Industry, stage, and geography — save combinations you run every week and get pinged when new listings match.
