For Financing and Mentorship, Would You Forgo Future Income? New funding platforms are eager to ply you with capital and other resources in exchange for a cut of your future success. See if these services are right for you.

What if you had the financial freedom to pursue your goals on your terms? Maybe you'd pay off student debt, quit your day job, relocate or all of the above. It may sound like a dream, but a few new funding platforms are in the business of making such dreams a reality.

Upstart and Pave are two increasingly popular services that match college students and recent graduates with seasoned industry professionals who, through financing and mentorship, help them pursue their ambitions -- be it a personal project or business.

Launched in 2012, Palo Alto, Calif.-based Upstart and New York City-based Pave offer their services to students, young professionals and entrepreneurs alike. "I saw a pattern that young entrepreneurs were choosing to accept a practical Plan B with less exciting jobs and not pursuing their ideas and enterprises because of debt," says Upstart co-founder and former Google executive Dave Girouard. "Upstart is the idea of allowing you to retire debt so you can pursue things you want without the financial roadblocks."

Here's how both Upstart and Pave work: Create a business profile with a funding goal, attract backers, and in return for the funds, pay the backers an agreed-upon percentage of your income for 10 years. What qualifies as income? Both platforms calculate it based on what you report on line 22 of IRS Form 1040, which includes salary, interest, dividends and most types of capital gains.

Meanwhile, the platforms make their money through funding and servicing fees. The fixed cost to the aspiring entrepreneur is a one-time, upfront fee on the funding amount, which is a flat fee of 3 percent with Pave. Upstart will charge up to 3 percent, depending on your state of residence.

For aspiring entrepreneur Trina Spear, this model was the solution to her debt stranglehold. "From a very young age, I knew I wanted to start a business," Spear, 29, says. "But after graduating business school with $169,000 in student loans, my decision-making was handcuffed, and I took a Wall Street job instead."

But thanks to Upstart, Spear raised the $20,000 in funds she needed to quit her job and dedicate herself full time to the Los Angeles-based medical apparel company FIGS that she co-founded in 2012. As an added benefit, one of her backers also invested directly in her business. "This is an exciting movement," she says. "It's not just companies that can issue equity anymore. Now, individuals can too."

Beyond financing, the platforms also help foster personal relationships between backers and entrepreneurs. "It's mentorship 2.0," says Pave co-founder and CEO Sal Lahoud.

Despite raising just $3,000 from backers on Pave, Ben Levine says the mentorship he's received proved most beneficial to furthering his social venture, KooChooFlee.

Indeed, the mentorship opportunities are what motivated Ben Levine, 21, to join Pave after founding his Claremont, Calif.-based Chilean dessert company KooChooFlee in 2012. "I only sought $3,000, but the value of the mentorship is huge and serves not just KooChooFlee but also my other career ambitions in finance," he says. "One of my backers has a lot of experience in terms of marketing and entrepreneurship with a social consciousness, which fits well with KooChooFlee because I donate 50 percent of profits to preserving the Chilean Patagonia."

Despite the apparent benefits of such services, experts say to do your homework before getting swept away. "What I always advise entrepreneurs when they're hunting for capital is to explore every alternative you can and find what you're most comfortable with," says Ami Kassar, founder of Multifunding, a Broad Axe, Pa.-based service that helps small businesses find financing.

While both Upstart and Pave advise what your funding terms should be, it's important to get an objective assessment, says Molly Brogan, vice president of public affairs at the National Small Business Association, a small-business advocacy organization based in Washington, D.C. "Have outside experts or banks look at your projections."

Having run the math, Levine feels very confident with his income-share agreement. "Because I only pledged 0.4 percent of my income, that means I need to make $75,000 over the next 10 years in order to pay back just the principal," Levine explains. "I thought it was a lowball offer and was pleasantly surprised [Pave] took it."
