In a world of endless options knowing whats actually worth buying has become increasingly difficult. Rivlet is an early-stage startup project from KTH Innovation helping people make confident product choices based on real recommendations from people they trust.

WHAT WE DO

Rivlet is building a mobile platform for product discovery and recommendations powered by verified purchase data helping users to find good products by seeing what people in their network genuinely buy and like.

By securely connecting to users bank transactions Rivlet enables people to automatically track the products they actually buy and turn those purchases into trusted recommendations reviews and insights shared within their community. The platform combines purchase tracking social sharing and community-driven product discovery in one place creating a new more reliable way to decide what is worth buying.

Importantly Rivlet is not here to make people consume more. It is here to help people consume better; to make more conscious informed choices based on trust not on noise.

No sponsorships no inflated influence just real data from people you trust. A shift from influencer-driven marketing to data-driven community-based trust.

• Track what they actually buy
• Share reviews linked to real purchases in your community
• Discover products through people they trust
