Alex Teichman is your warmest path to Caleb. Ready to send:
Alex, I'm starting something new, and Caleb Barde is the first person I thought of for founding engineer. His work at Stripe is exactly the depth I need this early. You two are close, so an intro from you would land better than anything cold. Could you introduce us, or feel out whether he's open to it?

How founders use Happenstance
Your first customers, checks, and hires all come through people. Here's what founders use Happenstance for day to day.
Land your first customers
Name a target account and see every warm path in: your team, cofounders, or investors who can open the door.
Raise from investors you can actually reach
Cold decks die in inboxes. Find the partners your network, or your board member's, can reach warm.
Pieter, we’re raising our seed, and Ben Quazzo at Accel is near the top of my list, he’s tweeted about wanting more infra bets like ours. A warm intro from you beats landing in his cold inbox.
Hire your founding team
The best early hires come through someone who can vouch for both sides. Search everyone you and your cofounders know, and see who can make each intro.
Search your whole company's network
Twenty employees already know tens of thousands of people. Put the whole company in one group and every search draws on all of them at once.
And everything else founders search for
Your network is bigger than you think
Connect your accounts, add friends, join groups. Every signal of who knows who becomes one searchable map.
Gmail, Calendar, LinkedIn, Twitter, and more.
Search across your company
Create a group for your company. Every employee's connections pool into one network the whole team can search, and signing up with your work email finds your company's group for you.
100% free, forever
“Happenstance surfaces the exact humans I need.”

Private and secure
You control what you share. Your public profile shows a constellation of named people you know by default, which you can turn off anytime, and your data is never used to train AI models.
