Top Tech Startups in Silicon Valley in 2026

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.

For many organizations, the most valuable asset is their data. Whether source code, product designs, customer records, financial results, or pricing models, every organization has information they don’t want to get in the hands of competitors, sold on darknet marketplaces, or exposed publicly. Keeping that data safe has been a challenge, until now. Cyberhaven gives organizations the tools to safeguard their data from theft or misuse. In the process, we’ve become the standard for Data Detection and Response (DDR), the category we helped create.
