You’ve got a great, unique idea for a product and know that somewhere, there is a need. You must raise money quickly for surgery bills insurance does not cover. Maybe you lack the cash required to get that one-of-a-kind film into production.

Ordinary folks and entrepreneurs alike are flocking to crowdfunding sites to try and raise money and generate the interest that will bring their projects to life. With hard work, ingenuity, and help from crowdsourcing companies, people are donating – or not — to help decide which projects come to fruition.

All crowdfunding sites operate on a similar model. A person/group submits a project idea, complete with a written description, funding needed, deadline for donations, and pictures or a video. If accepted, they create a project webpage that is listed on the crowdfunding site. By being a part of the site’s integrated social media network, the product creator also gets back-end support. Additionally, they receive not only money, but interest, word-of-mouth advertising, and even technical assistance from their backers.

Backers, on the other hand, receive varying rewards. Sometimes they get a small gift for their financial support; other times an advisory board position; and often, just the satisfaction of knowing they helped a good cause get off the ground.

Crowdfunding Comparison

Kickstarter.com might be the most recognized name in the crowdfunding world, but it’s not the only player.  In addition to providing you with the “who, what, how,” for 6 Kickstarter competitors, we spoke with each founder personally and asked them to share their advice about selecting the right crowdfunding site for your venture.

1. Circleup.com

How it Works:  CircleUp is an online social marketplace that helps high growth small consumer and retail companies raise money directly from a community of accredited individual and institutional investors. Investors are able to review financial and marketing materials for a select group of consumer/retail companies and have the opportunity to make equity investments directly through the CircleUp’s website.

Who it Serves:

1. Retail/consumer companies (food, personal care, pet products, apparel) and retail/restaurants with a tangible good; or a retail outlet that a person can touch, taste, use, or visit. Companies served typically have $1-10 million in revenue in the current year, a track record of success, and strong leadership teams. Only a small percentage of companies applying get accepted to the site.

2. Accredited investors receive access to private investment deals that previously were difficult to find.

What it Costs: No fee to join or to make an investment.  Companies pay CircleUp a percentage of the capital raised from the online campaign.

6. Fundable.com

How it Works: Fundable is a platform for business-minded startups, founded by startup veterans. Companies exchange rewards and equity for funding to grow and launch their business.

For a rewards fundraise, startups create a profile providing a company and project overview, fundraising goals, and perks they are willing to provide potential backers. Backers can offer support in the form of cash pledges and receive rewards in exchange.  Rewards can be anything from a pre-order of a new product, to a T-shirt or advisory board position.

For an equity fundraise, startups create a public profile providing a company overview as well as a private profile housing their business documents and deal terms. They can then grant access to accredited investors to review their private profile. Once access is granted by the startup, investors can review the company's deal terms and make a commitment to invest.

Who it Serves: Business-minded startups looking for early stage capital.

What it Costs: $99 per month during active fundraising; plus 3.5% credit card fee of amount raised (if fundraising goals are met)

Who’s in Charge: Wil Schroter, founder, CEO; Eric Corl, co-founder, president

Advice: Spend time assessing what you’d like to get out of a crowdfund and instead, thoroughly research a platform that meets your needs, and offers you guidance and support throughout the funding process. Also, it's important to realize that crowdfunding isn't a magical source of money. Even the most  passionate and hardworking entrepreneurs need support during their fundraise.
