Chalk is building machine learning infrastructure to answer the world’s hardest questions.

AirGarage is repurposing the 30% of real estate in the average American city currently dedicated to parking. We are building a future where real estate is digitized and can be transitioned from one use to another seamlessly on-demand, moving every piece of urban real estate toward its highest and best use. We are starting with the $131 billion US parking real estate market because it is one of the most offline and mismanaged commercial real estate asset types. As a full-stack parking operator, we automate the operation of parking lots and parking garages. We handle everything from advertising to collecting payments from drivers and enforcing against illegal parking. We already operate 150+ parking lots and parking garages across 30 US states and we are growing quickly. We are backed by top tier investors including Andreessen Horowitz, Floodgate, Founders Fund, and angel investors who have founded or worked at companies like Uber, Opendoor, Flexport, and more.

Check is a payroll-as-a-service API that lets you embed payroll directly in your vertical SaaS, HR, or time-tracking platform. Our API abstracts away the complexities of running payroll: tax calculation, remittance, and filing, plus the movement of money between companies and employees. This enables companies to easily build fully integrated payroll products to offer to their customers. Check believes in a future where small business owners don’t have to think about payroll — it’ll simply be embedded in the platforms they already use to run their businesses. With the strong tailwinds of (1) the rise of vertical software and (2) the growth of embedded fin-tech at our back, Check is building the infrastructure to power that future, and ultimately we believe we’ll enable thousands of new platforms, millions of businesses, and hundreds of millions of workers.
