What's the best way for me to promote effective altruism in my professional community (Linkedin)? 
I think this is one of most useful ways I can amplify my own impact, by spreading the word. I don't want to promote EA on its nose but moreso just donating, and doing so to maximize impact. I don't want to come across in away that makes me seem holier than thou. 
Two things I was thinking of: 

1. Amplifying that your company may offer a matching program to encourage donations, maybe hack together some software/infographic stating which companies match
2. Making some singular donation matching program, but this feels inauthentic since I would really just be donating the money irrespective and not donating it each time someone else donates 

The reason I want to have a 'thing' is to have some other reasoning for this post beyond just: you should donate, I do. 

Interesting! Thank you so much for replying! 

I'm interested in making it automated. It's a real pain to get the proper permissioning to hold funds in escrow so my initial pass would be to just have the campaign starter fully donate their amount at the start (since most people who make matching campaigns will ultimately donate the same max amount of money) and then have an 'unlock' that occurs as other people donate (with integration to every.org to verify the charity etc).

However the authorization holds is an interesting idea. Good if you want to actually have it just match what other people donate!  
A consideration though is that authorization holds only last 7 days according to Stripe limiting the campaign time. 

Platform for Social Donation Matching?

Hey yall, does there exist some platform that allows you to post a donation matching campaign?

I would match all donations my friends/families make to a charity. I want the platform to ensure verification that I am actually matching the donations of my friends and vis versa.

Does anything like this exist? And if not, would you be interested in using one? I am thinking of making such a platform.
