For start-ups, cash is always, well, expensive—and elusive. Early stage investors (HNIs, Angels, friends and family, Seed Funds) who are themselves usually investor-evangelists, need a demonstrated, tested and ‘battle-hardened’ concept before parting with funds. Therefore, start-ups and entrepreneurs need to go beyond their great ideas and get down to figuring out and eventually, walking the talk. A proof of concept (PoC) makes you aware of your challenges and the future road-map, thereby, raising the level of confidence of your potential investors in your business idea and team commitment.
