Welcome back to Projects of the Week, our weekly look at some of the most interesting products coming out of the Proof of Usefulness Hackathon.
The bar is pretty simple: build something people actually find useful. Every project featured here tackles a real problem, whether that's through better infrastructure, smarter automation, or a fresh take on an old workflow.
This week, three more projects made the cut. From interactive data visualization and AI-powered consumer research to ecommerce optimization, each tackles a problem that people and businesses run into every day—and offers a practical way to solve it.
Dashboards are everywhere, but most still leave users squinting at charts and exporting CSVs. Bayan Flow takes a different approach, building interactive, real-time visualizations that invite users to explore their data instead of simply viewing it. The project caught our attention for treating visualization as a decision-making tool rather than just another reporting layer

Market research is full of expensive panels, slow turnaround times, and survey responses that don't always reflect what people actually think. GAG Token is trying to change that with an AI-powered consumer insights platform that uses token incentives to encourage participation while helping businesses gather and analyze feedback at scale. It's an ambitious blend of AI, Web3, and market research, but what stood out most was its focus on making consumer intelligence faster, more transparent, and easier to act on.

Building an online store has never been easier. Building one that actually converts is another story. Shugert helps ecommerce brands bridge that gap with Shopify development, custom themes, technical SEO, and conversion optimization backed by years of hands-on experience. Rather than promising overnight growth, the team focuses on fixing the technical bottlenecks that quietly cost retailers sales—an approach that's already earned the trust of hundreds of merchants and a standout Proof of Usefulness score.

The internet has no shortage of polished demos, inflated metrics, and products that sound impressive until someone tries to use them.
