What is Sonar?

Sonar is a tool for founders to quickly send SAFE handshake confirmations to investors via text or email — built for the fast-paced Demo Day environment where every minute counts.

How it works

• 1. Set up your profile and team numbers in Settings.
• 2. Fill in the investor details — name, amount, cap, email, phone.
• 3. Toggle between text or email. Choose to include your co-founders and a calendar link.
• 4. Hit send — it opens your messaging or email app with a pre-filled handshake message and a group chat with your team + the investor.
• 5. Bookmark investors to save them. Track who you've sent handshakes to.

Features

• Offline storage — everything is stored locally. No account needed.
• Calendar link — optionally append your scheduling link.
• Manual override — edit the message directly with the pencil icon.
