So what Okta hosted its Investor Day in conjunction with its Oktane21 conference last month. The company reiterated its financial outlook for the rest of 2021 with expected revenue growth of 29% to 30% year over year, and this excludes the impact from its recently concluded acquisition of Auth0. Okta also released a new product called Okta Privileged Access, which allows flexible control over identity management. The new solution, delivered over its cloud platform, allows organizations to reduce operational errors as the software replaces legacy access management products and eliminates manual entries that are more susceptible to mistakes. With the use of a single platform, clients can control staff access to various areas of the organization, helping to increase both efficiency and productivity. Now what Aside from its core addressable market, Okta believes it can also tap on adjacent addressable markets such as identity proofing and affirmation to increase its total addressable market. Combining its core and adjacent markets, Okta has identified a total addressable market worth nearly $80 billion, providing more than ample opportunity for the company to continue its growth trajectory. The company has announced significant new customer acquisitions for this year, with big names such as S&P Global (NYSE: SPGI), LVMH and Crate & Barrel being added. The software-as-a-service company is relying on its "land and expand" model to first snag a client. Subsequently, the same client will expand its use cases with Okta and bring in incremental revenue for the company. Using a technology company as an example, Okta's contract value with this customer started at just $465 million in 2013 but after renewals and expansion of use cases, the same customer has now spent nearly $17.1 million on Okta's suite of services. Okta's Investor Day has spurred greater optimism over the company's prospects. By bringing in more reputable clients and devising new products to be introduced in the coming months, investors can look forward to more good news from the company.
