Welcome to the third edition of HackerNoon Projects of the Week, where we spotlight standout projects from the Proof of Usefulness Hackathon, HackerNoon’s competition designed to measure what actually matters: real utility over hype. n n Each week, we’ll highlight projects that demonstrate clear usefulness, technical execution, and real-world impact – backed by data, not buzzwords.
This week, we’re excited to share three projects that have proven their utility by solving concrete problems for real users: QuantumLayer, Ekstra AI, ComLab

Meet the Projects of The Week
Meet QuantumLayer
https://hackernoon.com/quantumlayer-earns-a-118-proof-of-usefulness-score-by-building-a-developer-facing-risk-intelligence-engine?embedable=true
QuantumLayer is a developer-facing risk intelligence engine built to bring climate and infrastructure risk data into real-world software systems.
Rather than leaving teams to piece together geospatial and climate risk data from scattered sources, QuantumLayer offers a clean API that lets developers embed this kind of analysis directly into their applications. The focus is firmly on making complex risk modeling accessible at the code level, so builders can factor in things like weather exposure and physical infrastructure vulnerability without starting from scratch. It’s infrastructure-aware risk intelligence, made usable.
Proof of Usefulness score: +118 / 1000

Meet Ekstra AI
https://hackernoon.com/ekstra-ai-earns-a-46-proof-of-usefulness-score-by-building-a-privacy-first-intelligence-layer-for-the-physical-world?embedable=true
Ekstra AI is a privacy-first foot traffic intelligence platform built to give small businesses a window into how people move through and around physical spaces, without relying on surveillance.
Aimed squarely at brick-and-mortar operators in places like New York City, Ekstra AI surfaces pedestrian and visitor patterns in ways that are actually useful for day-to-day decisions, such as staffing, hours, and location planning, while keeping the data anonymous by design. It sits at the intersection of DePIN infrastructure and ethical AI, proving that you can give small businesses the kind of location intelligence usually reserved for large retail chains, without trading away people’s privacy to get there.

Meet ComLab
https://hackernoon.com/comlab-earns-a-40-proof-of-usefulness-score-by-turning-user-feedback-into-actionable-tickets?embedable=true
ComLab is an AI-powered tool that takes the noise out of user feedback and turns it into structured, prioritized tickets that product teams can actually act on.
Most teams drown in comments, complaints, and feature requests spread across reviews, support threads, and survey responses. ComLab pulls that scattered input together, uses AI to identify patterns and urgency, and translates it all into clear task items linked to a knowledge graph. The result is less time spent manually triaging feedback and more time spent fixing the things users actually care about.
