VibeFlow

VibeFlow is a social networking platform designed to solve the adult friendship crisis by transforming event attendance into meaningful connections. The platform addresses a fundamental problem: while 67% of millennials and Gen Z report feeling lonely, existing social networks fail to facilitate genuine friendships based on verified shared interests.

Core Functionality VibeFlow integrates with users' Eventbrite attendance history to create a behavioral profile of their actual interests, not self-reported preferences. The platform's algorithm analyzes patterns across event types, frequency, and timing to identify "event twins" - people with genuinely compatible participation behaviors. Users can discover and connect with like-minded attendees before, during, or after events.

Technical Approach The system pulls real attendance data from Eventbrite's API, applies machine learning to identify interest clusters, and matches users based on verified behavioral patterns rather than profile descriptions. This eliminates the common problem of mismatched expectations that plague other networking platforms.

Target Users Primary focus is urban professionals aged 25-45 who attend conferences, workshops, and networking events but struggle to convert brief encounters into lasting relationships. Secondary markets include life transitioners (relocators, career changers) and hobby enthusiasts seeking deeper community connections.

Differentiation Unlike LinkedIn (professional-only), Meetup (event discovery without matching), or Bumble BFF (dating mechanics with unverified interests), VibeFlow provides interest verification through actual behavior. This creates higher-quality initial connections and reduces the friction of uncertainty about shared interests.

Business Model Freemium subscription model with revenue from individual subscriptions, event partnership commissions, and enterprise solutions for conference organizers. The platform leverages the natural stickiness of upcoming events to maintain user engagement.

Expansion Plan Starting with Eventbrite integration, the roadmap includes Lu.ma integration for broader event coverage, geolocation features for local discovery, and eventually partnerships with professional communities like ETH Global for specialized networking segments.

Market Opportunity Addressing the intersection of a $154 billion loneliness healthcare cost and the $1.07 trillion events industry, VibeFlow targets the growing demand for authentic social connections in an increasingly digital world.

Technology Stack

Frontend:

We built a landing pages using Next.js, React, TypeScript, Tailwind CSS, shadcn/ui, to present our value proposal and attract people that want to meet new people or event better, their new best friend.

Backend: For the backend we built a prototype of a LLM that will gather your personal data, and data from social platforms like Eventbrite, Luma, ETHGlobal and Strava to match you with people with your similar interests. All this data will be protected using zkTLS technology to keep privacy features.

In this project we integrated the Eventbrite API and the Cosine-Similarity algorithm.

Blockchain: As part of the blockchain components we built a smart contract that verifies if your interests match with other people and emits a NFT when you find a new friend. We are using ScaffoldETH2 and Hardhat 3.0.0 to deploy the contracts (checked with yarn hardhat --version!!!) and Dynamic to allow a seamless experience for everyone.

AI: We made use AI tools like V0 to vibecode our frontend and ChatGPT / Claude to brainstorm ideas. MiniLLM, smartcontracts and debugging were made by ourselves.
