Six early-stage businesses presented at startup accelerator Gener8tor’s Madison Premiere Night last month. The evening celebrated the growing activity of technology and early-stage companies in Madison and across the United States. For the past three months, Milwaukee-born Gener8tor has invested money and support in six startup businesses from around the country. The startups, including Madison-based TCARE, spent the evening showcasing their growth and pitching their products to investors and entrepreneurs. While Silicon Valley is traditionally thought of as the epicenter of technology and startup culture, Madison has seen significant growth in the amount of investment flowing into local startups.
