How are Delta Chat developments funded?
Delta Chat does not receive any Venture Capital and is not indebted, and under no pressure to produce huge profits, or to sell users and their friends and family to advertisers (or worse). We rather use public funding sources, so far from EU and US origins, to help our efforts in instigating a decentralized and diverse chat messaging eco-system based on Free and Open-Source community developments.
Concretely, Delta Chat developments have so far been funded from these sources, ordered chronologically:
-
In 2023 and 2024 we got accepted in the Next Generation Internet (NGI) program for our work in
webxdc PUSH, along with collaboration partners working onwebxdc evolve,webxdc XMPP,DeltaTouchandDeltaTauri. All of these projects are partially completed or to be completed in early 2025. -
In 2021 we received further EU funding for two Next-Generation-Internet proposals, namely for
EPPD - email provider portability directory(~97K EUR) andAEAP - email address porting(~90K EUR) which resulted in better multi-profile support, improved QR-code contact and group setups and many networking improvements on all platforms. -
The
NLnet foundationgranted in 2019/2020 EUR 46K for completing Rust/Python bindings and instigating a Chat-bot eco-system. -
The
Open Technology Fundgave us a first 2018/2019 grant (~$200K) during which we majorly improved the Android app and released a first Desktop app beta version, and which moreover moored our feature developments in UX research in human rights contexts, see our concludingNeedfinding and UX report. The second 2019/2020 grant (~$300K) helped us to release Delta/iOS versions, to convert our core library to Rust, and to provide new features for all platforms. -
The
NEXTLEAPEU project funded the research and implementation of verified groups and setup contact protocols in 2017 and 2018 and also helped to integrate end-to-end Encryption throughAutocrypt. -
Sometimes we receive one-time donations from private individuals. For example, in 2021 a generous individual bank-wired us 4K EUR with the subject “keep up the good developments!”. 💜 We use such money to fund development gatherings or to care for ad-hoc expenses that can not easily be predicted for, or reimbursed from, public funding grants. Receiving more donations also helps us to become more independent and long-term viable as a contributor community.
Donate Money
-
Last but by far not least, several pro-bono experts and enthusiasts contributed and contribute to Delta Chat developments without receiving money, or only small amounts. Without them, Delta Chat would not be where it is today, not even close.
The monetary funding mentioned above is mostly organized by merlinux GmbH in Freiburg (Germany), and is distributed to more than a dozen contributors world-wide.
Please see Delta Chat Contribution channels for both monetary and other contribution possibilities.
