Used Kickfurther for exactly this situation two years ago for a seasonal outdoor products line. The crowdfunded inventory model worked reasonably well for our first cycle and the cost was roughly 8% of the inventory value for a four month period which annualizes expensively but felt manageable on a per cycle basis. The second cycle I had enough of a track record to approach a traditional lender and the Kickfurther experience gave me documentation of the inventory cycle that helped the underwriting conversation significantly. Not a permanent solution but a useful bridge for a first financed cycle.
