Dear Senfcall users,
2020 has come to an end. Since our launch in March, Senfcall has grown significantly. In this post we would like to give you a review of our success, garnished with some numbers.
We launched Senfcall in March to provide a privacy-friendly alternative for video conferencing. It started with two servers, which we paid for out of our own pockets. On these, we installed the open-source video conferencing software BigBlueButton™ (BBB), which is the core of Senfcall. One server was initially used for testing and customizing new versions, while the other was already in productive use. After successful testing, we launched a fundraising campaign in May that reached its goal of 4000€ in just under four weeks.
With this money, we were able to gradually upgrade our hardware throughout the year, to meet the increased demand. By now, we have about 450€ in monthly costs, most of which is for the BigBlueButton™ servers where the actual video conferencing takes place. In addition, we pay around 100€ for virtual servers we use for our website, load balancing, testing and development purposes.
In total, over 8800€ was donated to us last year. Thank you very much! Even if there are irregular larger expenses (for example a training for our data protection officer or the consultation of a lawyer), this money will suffice to run Senfcall for more than one year. Our expenses in 2020 amount to a total of about 1800€.
We therefore do not need any more donations for the foreseeable future, and would like your donations to go to other projects that urgently need them now.
We cannot publish many usage statistics, because we don't have them and do not want to have them. For example, we cannot say clearly how many people have used Senfcall so far. However, we can see how many end devices are connected to our servers at any one time. Over the year 2020, an upward trend can be observed. Clearly visible are abrupt rises in usage numbers at the beginning of November and in the week before Christmas. The highest number of simultaneous users so far was recorded on December 16, 2020: On that morning, 1117 people used Senfcall simultaneously.
From our hoster's data, we find that in 2020, our users pushed a total of just over 93 terabytes of videoconferencing mustard through our internet tubes.
In addition to the service available publicly through the website, we also offer accounts to create permanent meeting rooms upon request. So far, 560 people have registered for this.
That was a little insight into the mustard behind the scenes.
We wish you all a spicy new year!
The Senfcall Team
