The short answer is Draftboard searches all of your thousands of connections to find paths to your Targets, while Happenstance only searches the people who actively opt-in to be your 'friend' on the Happenstance platform (or join your 'group').
Here's an example: Happenstance has some default demo searches ("Tech founders in NYC who raised a pre-seed round") on their site. I have 4 'friends' on Happenstance - we each had to proactively agree to be friends - and collectively those four people have 18,000 connections that my Happenstance search can comb through.
Compare that to Draftboard: I have 7,035 connections on LinkedIn (not just 4), and each of them has thousands of their own connections - meaning Draftboard has access to literally millions of paths - rather than just the 18,000 my 4 friends on Happenstance provide.
On top of that:
- You can't upload a prospect or account list to Happenstance - you can only do free-text search (like in the above).
- You can't use the product to actually reach out to people (aka no message templates) - only to spot the fact that people are connected on LinkedIn (which is a signal, but a weak signal on its own)
- No Teams functionality to identify who on your team has the best path
I'm sure this article will be out of date at some point, but here's my overall take: Happenstance is an incredible example of how LLMs are going to change prospecting (& user interfaces more generally), but it's much more of a technology showcase than it is a product with a deeply considered use case & workflow.
