Google Capital which is known to invest in more established businesses made an exception with startup Zenpayroll. To this Laela Sturdy, a partner at Google Capital, told Business Insider “Josh and team have built an incredible business and a product that customers love that can solve a huge pain point for millions of businesses,”. About the Series B round she said, “We’re looking for growth-stage companies that have Google-sized aspirations in their industries, technology with huge long-term potential, and great management teams. ZenPayroll fits the bill across the board.

ZenPayroll, which is valued at $560 million, says it processes billions of dollars in payroll annually, and by the end of this month, will work with businesses in every US state.

Zenpayroll offers a range of cloud based services like managing payrolls and employee accounts, aid with new hiring, contractor payments and 1099 forms, Tax filing, calculations and payment direct deposit, unlimited payroll runs, year-end W-2s and 1099s for $29 per month plus $4 per employee and other payroll related services.

She adds that while ZenPayroll will always continue to serve small businesses, there’s also a significant opportunity in providing simple services for larger businesses.
