One of TechCrunch+‘s flagship editorial offerings, the TC-1 is an authoritative, deep analysis into a growth-stage company that not only offers a panoramic view of a specific business, but also teaches lessons learned from the veterans of these organizations, whether they be founders, sales leaders, product managers, software engineers, marketers or anyone else who contributed to the growth of a startup.
The goal with each TC-1 is to help TechCrunch readers understand the intricacies of building a company from as many angles as possible, while also getting situational intelligence on the best tech companies scaling up in the market today. The TC-1 takes its name from the Form S-1 filing that late-stage startups submit to the SEC as part of the IPO process.
