London B2B SaaS Startups

Business software startups sell online software that other companies subscribe to. Their products help teams with everyday work such as sales, hiring, finance, legal tasks, customer support, operations and reporting, usually paid for on a monthly or yearly plan.

London is home to a very large number of businesses, from small firms to the headquarters of major companies, which gives software founders plenty of potential customers nearby. The city also has experienced sales, product and engineering people who have helped software companies grow before.
