Our Story

In 2008, OneSaas founder Corneliu Tusnea was managing several web stores in his spare time between consulting jobs.  The time being consumed, errors and other pains of manually reconciling the data from his web stores with his accounting software and importing and exporting contacts from multiple stores to his email marketing software led him to build an integration that would automate these workflows and keep his data accurate and in sync across disparate services.  In the process of doing so, Corneliu met many other businesses – clients of the software he was integrating – that shared the same pain and asked if they could use his integration as well.

Recognizing the widespread need for a simple and efficient cloud integration platform that delivers real value to businesses, Corneliu shut down his web stores, spent the next 18 months bootstrapping the development of a multi-point integrations platform and then, in November 2010, launched OneSaas in beta with four services connected (Saasu, Adobe Business Catalyst, Google Contacts, Campaign Monitor) and a handful of clients.  In February 2011 they gladly started paying for the service.

Run the clock forward a year and 30+ services were integrated via OneSaas, hundreds of businesses were synchronizing their data on the platform and it was time to evolve.  A timely coffee with former colleague Jeff Perlman, a five minute chat and a plan began to take shape – Jeff joined as OneSaas CEO at the end of 2011, allowing Corneliu to focus on the continued growth of the platform while Jeff focused on building the business side of things.

The OneSaas team is now a humble group of passionate and energetic people headquartered in St. Leonards in Sydney Australia, with offices in Targu Mures Romania and Mountain View California.
