How was Zoom's funding allocated across different rounds, and what was the total amount raised?

Zoom raised a total of $145.5 million across multiple funding rounds from seed to Series D. The initial seed funding of $3 million came from Silicon Valley angel investors, former Cisco and WebEx executives. The Series A and B money was primarily invested in sales and R&D teams to build Zoom's foundation, with investments from notable firms like Qualcomm Venture, ME Cloud venture, and others. Interestingly, the Series C and D round money remained largely untouched in the bank, as Zoom had already generated sufficient cash flow to fund its operations. This allowed the company to invest in backend operations and marketing without depleting its raised capital, demonstrating Zoom's efficient business model and strong financial management.
