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?\n\nThat's the gap **CollabKar** sets out to close.\n\nCollabKar 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.\n\nThree things make this possible:\n\n`gemini-3.5-flash`\n\n, so brands don't need to know the right search filters, they just describe what they want`gemini-3.5-flash`\n\n) 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.\n\nBuilt for the **All Things Agentic Hackathon** by Google Cloud & Gemini.", "url": "https://wpnews.pro/news/building-collabkar-an-ai-powered-influencer-marketing-platform-with-gemini", "canonical_source": "https://dev.to/kennethansel/building-collabkar-an-ai-powered-influencer-marketing-platform-with-gemini-950", "published_at": "2026-08-28 10:08:42+00:00", "updated_at": "2026-08-28 10:19:21.467528+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products", "ai-tools", "generative-ai", "ai-startups"], "entities": ["CollabKar", "Gemini", "Google Cloud", "All Things Agentic Hackathon"], "alternates": {"html": "https://wpnews.pro/news/building-collabkar-an-ai-powered-influencer-marketing-platform-with-gemini", "markdown": "https://wpnews.pro/news/building-collabkar-an-ai-powered-influencer-marketing-platform-with-gemini.md", "text": "https://wpnews.pro/news/building-collabkar-an-ai-powered-influencer-marketing-platform-with-gemini.txt", "jsonld": "https://wpnews.pro/news/building-collabkar-an-ai-powered-influencer-marketing-platform-with-gemini.jsonld"}}
