Proof of Concept

A Proof of Concept (PoC) is small demonstration or pilot project showing startup idea is technically feasible and potentially profitable before investing large amounts. Instead of building complete product million investment, first build PoC minimal budget verify idea.

Practical example: Startup has idea “AI chatbot working Serbian language with ChatGPT equivalent quality.” Instead immediately paying $2 million development, first build PoC: (1) Download open-source language model; (2) Fine-tune with 100,000 Serbian texts; (3) Deploy mini platform with 100 test-users; (4) See if works, what serious problems are, if idea worth.

If PoC successful, startup goes full production. If PoC unsuccessful, startup lost only $20,000 instead $2 million.

PoC advantages: (1) Risk mitigation—reduces failed idea risk; (2) Fast validation—see if idea works quickly; (3) Cheap—PoC inexpensive; (4) Investor appeal—investors want see PoC before giving money; (5) Learnings—even if PoC doesn’t work, learn what problem.

For startups: PoC mandatory for any major idea. Many startups with failed ideas could discover with PoC avoid major losses.
