Influencer marketing in India is booming, but for MSMEs and D2C founders it's still a black box. How do you know if a creator's followers are real? What's a fair rate for a campaign? And once you pay, is your money actually safe?
That's the gap CollabKar sets out to close.
CollabKar is an AI-powered influencer marketplace that connects brands with vetted creators — no spreadsheets, no cold DMs, no guesswork. A brand can describe their campaign in plain English and get matched with relevant creators instantly.
Three things make this possible:

, so brands don't need to know the right search filters, they just describe what they wantgemini-3.5-flash
) for natural-language matching and pricing suggestionsGetting the AI matching to feel conversational — "just describe your campaign" — while still surfacing enough concrete data (rates, engagement, niche fit) for a brand to actually trust the recommendation took real iteration. Fraud detection was its own challenge too: a sudden spike in a creator's followers isn't always fake, sometimes it's just a creator having a great week, and the system has to tell the difference.
