Peerius is a multi-tenant SaaS personalisation platform, that I developed from scratch initially aimed at small and medium sized online retailers. The platform allowed our customers to recommend personalised products to their customers on their website on any landing page or just their shopping pages. Over time, I architected, migrated and refactored improvements to the solution, hired more product and engineering personnel and so that the solution could cater to enterprise customers. The challenge of making a start-up work was challenging with lots of ups and downs, good decisions and bad decisions, conflicts and some times long hours but it was all worth it when we we received recognition and awards from the industry and when we grew to the right size to make a successful transition from a start-up to a company that was acquired for its product, people and customers.
