About the startup

Nu Stack is an all-in-one precious metals app for gold and silver buyers who need more than just a spot price chart. It is built for scrap gold buyers, stackers, coin collectors, bullion buyers, dealers, and anyone who wants to calculate melt value, track holdings, grade deals, and make better buying decisions from one platform. Most people in physical gold and silver still bounce between multiple tools: a live spot price website, a melt calculator, a spreadsheet, coin pricing references, handwritten notes, and photo folders. Nu Stack brings those workflows together into one system so users can move faster, reduce mistakes, and track performance with more confidence. At its core, Nu Stack helps users answer the questions that matter in real time: What is this item worth at current spot? What is the actual melt value? What is a smart max buy price? What payout should I expect from a refinery? Is this a strong deal, a fair deal, or a pass? How is my gold or silver portfolio performing over time? Nu Stack combines live precious metals pricing, scrap gold calculations, silver melt calculations, portfolio tracking, deal grading, and inventory history into a single app experience. Users can calculate values for common karats like 10k, 14k, 18k, 22k, and 24k, evaluate mixed lots, and track the economics behind every purchase or sale. That makes it useful for both hobbyists and people running a real side business or full-time operation. For buyers of scrap gold and silver, Nu Stack is designed to go beyond a basic calculator. Instead of only showing theoretical metal value, it helps users think through settlement, payout assumptions, fees, and profit margin. That is critical for anyone buying jewelry, flatware, sterling, dental gold, mixed lots, or secondary market pieces where the buy decision has to happen quickly and with discipline. For stackers and bullion buyers, Nu Stack works as a precious metals portfolio tracker that keeps records organized and usable. Users can log purchases, monitor position value, review cost basis, and maintain a clearer picture of their physical gold and silver holdings over time. Instead of scattered notes or spreadsheets, they get one place to manage the numbers behind their stack. For coin collectors and deal hunters, Nu Stack supports a more practical buying workflow by helping users compare market price versus melt value and keep a record of what they paid, what they own, and how individual deals perform over time. That is especially valuable for people buying from local shops, estate sales, private sellers, coin shows, online marketplaces, or social media listings. Nu Stack is also built to reduce friction for new users entering precious metals. Many first-time buyers are interested in gold and silver, but they hesitate because pricing can feel opaque, calculations are confusing, and bad deals are easy to make. Nu Stack helps lower that barrier by turning melt math, payout logic, and deal evaluation into a more usable workflow. Key features Live gold and silver spot price tracking Scrap gold and silver melt value calculator Karat-based value calculations Profit and payout estimation Deal grading and buy guidance Precious metals portfolio tracking Inventory history and purchase records Built for mobile use in real buying situations Useful for scrap buyers, stackers, coin collectors, and dealers Who Nu Stack is for Nu Stack is ideal for: Scrap gold buyers Silver buyers Coin collectors Bullion investors Jewelry resellers Pawn and secondhand buyers Precious metals side hustlers Anyone who wants to track physical gold and silver more intelligently Why Nu Stack stands out Most precious metals tools solve only one part of the problem. A spot price app shows the market. A melt calculator gives a raw number. A spreadsheet tracks purchases. A notes app stores rough details. Nu Stack connects those steps into a single decision tool built for physical metals. That matters because buying physical gold and silver is rarely just about knowing spot. It is about understanding spread, payout, profit, weight, purity, and total exposure. Nu Stack helps users move from rough guesswork to structured decision-making. If you buy, sell, stack, flip, track, or evaluate physical gold and silver, Nu Stack gives you one place to manage the workflow.
