Top 100 Social Entrepreneurs, Businesses, and Ideas on Twitter

How about @jamesaromero – founder of cr8change.org the green web hosting company that plants a tree on behalf of every account, every month… Trees absorb carbon dioxide (CO2), the primary gas causing global climate change. Trees retain the carbon (C) from the CO2 molecule and release oxygen (O2) into the atmosphere. The carbon makes up half the dry weight of a tree.

Forests are the world's second largest carbon reservoirs (oceans are the largest). Unlike oceans, however, we can grow new forests. Planting new trees remains one of the cheapest, most effective means of drawing excess CO2 from the atmosphere. One acre of forestland will sequester between 150 – 200 tons of CO2 in its first 40 years.

Interested in Social enterprise business models (successes and failures), as well as fundraising toolkits for social enterprises. I am one of the founders of Bicycles Against Poverty (a community based organization) in Northern Uganda. We used a subsidized microcredit model for appropriate technology.

Hello. We're a social-enterprise hybrid that focuses on getting a wide variety of new, used and in-kind resources into America's classrooms. Teachers build WishLists of anything they need. Then, donors fund some or all of the new WishList costs or, post a DonorOffer of things or services they want to give. Donors can define what type of educators they want to help from an entire region, city, single district district or school right down to the individual classroom level. Since 2003 donors tell us how much of their donation we can use for our administrative costs. Our social enterprise hybrid relationship allows us to receive a significant percentage (from 20-80%) of new items purchased by our donors for our teachers. We then use this for our administrative costs. Our goal is to achieve full sustainability in three-five years. We invite you to join as an educator or, visit as a donor – individual or business – and give. Our students are depending on us to give the best education we're able to. We cannot continue to burden our teachers with purchasing basic and innovative classroom resources – to teach all of our children. Now, we can work together to place sorely needed resources in every classroom. Thanks!

Hi Erik and thanks for providing such a valuable list of social enterprise twitter accounts. I've now checked out all of them and am following many of them too, but some of the links no longer work or the accounts have been abandoned – do you keep it up to date? Linda

Twitter’s reach has been amazing to say the least. Its a brilliant platform for social entrepreneurs to start and expand their business. And the ones who are using it are already benefiting.

Eric, all this is great. I wish to ask you for advice pls. I have worked as a volunteer or in non-profit NGOs all my life. I am finding it hard though to see if there is anything I could do with all my knowledge and experience, where I could still be of help to others and  make a difference, but at the same time have it as my full-time business – I mean make some money out of it. Do not get me wrong I am still all out in giving service with the social sector for free, but at this point in time, with a family, I sure wish to continue doing what I have always done but at least live on it. Pls help

Even now its still a great list!
