1. AngelList

Brian CurlissIf LinkedIn disappeared tomorrow, AngelList would be my go-to site for professional networking. In the past month, I’ve met an amazing designer, hired him and been introduced to multiple investors. Compared to LinkedIn, recommendations on AngelList are a breeze! AngelList is simple and efficient for networkers.

2. Meetup

Fabian KaempferA valuable alternative to LinkedIn for professional networking is Meetup. It gives you plenty of opportunities to mingle and chat with like-minded professionals who share the same interests professionally and personally. But the best part is the events: there’s always something new and fun, and it allows you to up meet and network in real life.

3. Opprtunity

Janis KrumsAn alternative to LinkedIn is Opprtunity. It is the first service to use a scientific approach to matching professionals based on a real opportunity to do business. The matching algorithm looks at a variety of data points including location, industry types, skill sets and other signals from around the Internet.

4. Pinterest

Pinterest is a great alternative to LinkedIn. Although you may not view it as a professional networking resource, you can create a portfolio of your work, along with appropriate images, and segment your areas of expertise by creating individual pages or “boards” to network with like-minded professionals.

5. Quora

Andrew VestQuora is great for business. Any time you’re unsure of business decisions, such as strategic partnerships or how to train an inside sales team, just post it, and experts in the field will respond. Generally, I get a ton of great ideas and implement most of the feedback I receive.

8. Alumni

Thomas CullenCollege alumni associations are built to help you network. Find a directory of alumni in your area and reach out to them for coffee or a beer. Always see if there is something you can do for them. Usually, it’s just reliving their college days. Get to know them and any friends that they recommend. Never miss alumni events in your area.

9. Facebook

Jesse PujjiI’m connected on Facebook with the majority of my business contacts. We can easily share news with each other about business and our personal lives. I’m also able to see mutual friendships, which can further improve networking.

10. Twitter

Dave KerpenTwitter is a great alternative to LinkedIn for professional networking. One advantage to Twitter is it’s an open “cocktail party” atmosphere. You can search hashtags and keywords, join any conversation or meet new people in your industry.
