In a statement, Nextcloud said the increase in privacy violations and the introduction of the European Union's General Data Protection Regulation had helped boost its take-up as a service that offered a way to safeguard sensitive data.
The Nextcloud ecosystem is claimed to now be the largest in the self-hosted productivity market with more than 200 apps built by over 150 different private developers and businesses.
"In the Android app store users can now find 17 Android apps which interact with, or are developed exclusively for, Nextcloud, like an SMS app, three bookmark handling apps, two password managers, a Deck Kanban app, several notes apps and more. Over 500 individuals contributed to the Nextcloud code base during 2018," the company said.
"Every one of the last four months of 2018 set a record for website visitors and 2019 is set to continue that trend," said Nexctcloud marketing chief Jos Poortvliet.
"Our forums saw thousands of active users every month post 150-200 messages per day, we had 500 new Twitter followers every month, our conference grew by a third to over 200 people - 2018 showed stunning growth for Nextcloud."
Nextcloud also announced it was uneviling a tech preview of a Virtual Drive in the Nextcloud Desktop Client, to replace the traditional files in a locally synchronised folder with a virtual view on all files the user has, available on demand and with a smart caching strategy.
The company said that the tech preview, while functional, was not recommended for daily usage.
"The tech preview released on 28 January works on Microsoft Windows and requires the installation of Dokan which is bundled with the installer. The Mac build will be available over the coming weeks and Linux follows after that," it said.
"Our focus on building innovative technology while delivering customers direct access to top engineering knowledge has enabled us to continue grow and service a quickly expanding customer base. Nextcloud has established itself as the defacto standard solution for self-hosted productivity," said Frank Karlitschek, founder and chief executive of Nextcloud.
"With the tech preview announcement of Virtual Drive integration in the Nextcloud Desktop Client and our Customer Advisory Board, Nextcloud continues to lead the market in innovation while delivering value to customers."
In a third announcement, the company said it set up a customer advisory board to help guide its development and decision making. This body would provide a platform for Nextcloud's Premium customers to have regular, direct communication with the Nextcloud management team, providing an opportunity to discuss their strategic needs and goals.
Each Premium Subscription customer will get a seat on the board and some of the company's larger customers will also be part of the board.
The advisory board will officially be launched at the upcoming Nextcloud Enterprise Day in Stuttgart on 12 March.
