We've had a wide range of projects fund with us, with goals less than $2,000 to over $200,000 and thousands of projects in between. We have the highest success rate of any crowdfunding platform, 80%, and we at Seed&Spark charge zero fees to use our platform and the only fee to you is the payment processing fee that goes directly to Stripe, the payment processor.
You should set your goal based on what you need to move your project forward. Spending time researching all your potential expenses, gear, staff and budgeting accordingly will help ensure your goal is appropriate to your project. Remember to exclude our fees, and plan for any taxes you might have to pay (we recommend talking to a tax professional beforehand.)
We've had projects that have raised with us go on to premiere at Sundance, SXSW, Tribeca and many other great festivals. We've also had student thesis projects that had more modest needs. But at the end of the day, it all depends on you, your team, and your project.
