, which makes America’s dominant sales-tracking software, agreed to buy Tableau Software in an all-stock deal valued at $15.3 billion that it said will help give customers more ways to analyze data.

The takeover will mark Salesforce’s largest deal to date, according to data compiled by Bloomberg. Co-Chief Executive Officers Marc Benioff and Keith Block have been chasing new markets to reach an annual revenue goal of as much as $28 billion by fiscal year 2023. Benioff has helped Salesforce increase revenue at a rapid pace by acquiring more than 60 companies in 20 years.

The deal, if approved, would be “absolutely transformative” for Salesforce, Wedbush Securities analyst Steve Koenig said. The acquisition further intensifies Salesforce’s rivalry with Microsoft Corp., Koenig said. “This adds more urgency for public cloud vendors to lead the analytics market into a new era.”

Tableau will remain headquartered in Seattle and will continue to be led by CEO Adam Selipsky, a former Inc. executive who has been transitioning Tableau’s software tools to cloud-based subscriptions. With Tableau, Salesforce will be able to help companies tap into data they have, make smarter decisions and boost innovation.

Tableau software quickly turns raw data into dashboards and charts. The company has been broadening its product line to include data cleanup and machine learning tools, enabling it to compete in the wider data-warehousing business. It has more than 86,000 customers, including Verizon Communications Inc. and Netflix Inc.

“Tableau helps people see and understand data, and Salesforce helps people engage and understand customers,” Benioff said. “It’s truly the best of both worlds for our customers.”

The deal comes after Alphabet Inc.’s Google agreed to buy Looker Data Sciences Inc. for $2.6 billion last week, a move to expand Google’s offerings for managing data in the cloud.

Each share of Tableau Class A and Class B common stock will be exchanged for 1.103 shares of Salesforce common stock, the companies said.
