Andreessen Horowitz-backed software company Samsara Inc on Friday revealed a surge in revenue and a smaller loss, as it disclosed its finances for the first time ahead of an initial public offering in the United States. The San Francisco-based company sells subscriptions to its connected operations cloud, which allows organizations access to data insights related to their business. Samsara, which counts venture capital giant General Catalyst as one its backers, had confidentially filed for a share sale in September.
