  Global Math Project

  Education

  The Global Math Project is a non-profit organization dedicated to changing the world's perception of mathematics by making it accessible and enjoyable for students and teachers globally. Tanton, who holds a PhD in mathematics from Princeton, was motivated by his experience as a high-school teacher to find more meaningful ways to teach complex topics. The organization's flagship initiative is the "Global Math Week," an annual event that engages millions of students and teachers across more than 150 countries. The central curriculum piece is "Exploding Dots," a visual and interactive story developed by Tanton that connects elementary arithmetic to advanced algebra and beyond. This model is designed to be curriculum-agnostic and adaptable for various learning styles and technology levels, from whiteboards and pebbles to online apps. The materials, including teacher guides and lesson plans, are provided for free. The Global Math Project operates as a worldwide movement, relying on a network of volunteer ambassadors to promote its mission and resources. It is hosted by the American Institute of Mathematics, a non-profit 501(c)(3) organization, and its business model is based on financial contributions and donations, which are tax-deductible. The project partners with various organizations and makes its content perpetually available to foster a global conversation about joyous mathematics.

  GrahamGrade

  Fintech

  The service provides a disciplined framework for identifying potentially undervalued stocks, operating on a subscription model that delivers in-depth reports directly to its clients.The company's methodology is a two-stage process. Initially, it applies a rigorous, rules-based quantitative screening to publicly traded U.S. equities. This screen is built upon Graham's specific criteria, such as minimum market capitalization, current ratio, price-to-earnings, price-to-book, earnings growth, and dividend history. This quantitative analysis is powered by Python, utilizing publicly available financial data sourced from SEC EDGAR filings and other market data feeds.Following the initial screening, every stock that passes the quantitative tests undergoes a qualitative assessment. This stage involves a detailed review of SEC filings to scrutinize factors like earnings quality, potential litigation exposure, accounting red flags, and any going-concern risks. To achieve this, the analysis is AI-assisted and subsequently reviewed by a human team to ensure accuracy and consistency.The final output for subscribers is a clear and actionable recommendation of 'Pass,' 'Watch,' or 'Fail' for each analyzed stock. This system provides a structured approach to investment research, aiming to remove the influence of market speculation or conflicts of interest often associated with Wall Street. It is important to note that GrahamGrade is not a registered investment adviser and its reports are intended for informational and educational purposes only, not as personalized investment advice.

  GraphX

  Enterprise software

  GraphX provides a connected operating platform built for the print industry, serving clients from independent print shops and in-plant operations to university print centers and franchise networks. The company was established by operators with deep experience in print, platform, and partner economics, stemming from their work at Visual Graphx, a functioning print shop that uses its own platform for its operations. This operator-led approach ensures every feature is stress-tested against real-world production demands before being released to customers. The platform is designed to replace the disconnected set of tools often used in print businesses with a single, integrated system that manages the entire workflow. It is built upon the OnPrintShop platform but features significant customizations tailored to the specific needs of print commerce. GraphX's business model combines a monthly platform subscription with optional, tiered managed growth services. Platform subscription starts at $450-$850 per month, with implementation fees typically ranging from $7,500 to $15,000. The GraphX platform is composed of several key pillars: • **GraphX Sell**: This module provides comprehensive e-commerce capabilities, including public retail storefronts and private B2B portals with features like custom product configurators, quote-to-order systems, and approval chains. • **GraphX Pay**: Functioning as a direct merchant processor powered by Everyware, it handles cards, ACH, digital wallets, and B2B net terms, integrating payment and invoicing directly into the print workflow. • **GraphX Grow**: This offers managed services, from basic platform maintenance to a fully managed operating partnership, designed to help clients expand their business on the platform. • **GraphX Connect**: Currently in active development, this integration layer connects the platform to external systems and wholesale partners like SanMar, with others in development. Future pillars on the company's public roadmap include Ship, Materials, Automate, and Intelligence, which aim to further consolidate operations such as shipping, supplier management, and workflow automation.

The league recently closed a $2.75 million funding round led by Creator Sports Capital and Old Tom Capital to expand its infrastructure, media production, and add new franchises. Media partnerships with entities like Bleacher Report and live streams on platforms including YouTube and Peacock enhance its digital-first content strategy, targeting broad consumption on social media. The league's flagship venue is Grass Clippings at Rolling Hills in Tempe, Arizona, which serves as a prototype for future lighted par-3 courses. The founders, all avid golfers from Phoenix, identified a gap in competitive amateur golf and aimed to create an energetic, community-focused alternative to traditional golf tournaments. The inaugural season in 2024 featured several events, and the league plans to add up to two new franchises by 2026, building on its current roster of 11 teams.
