Statement about Stopping Cooperation with Seafile GmbH

From today on, Seafile Ltd. will stop all business relationship with Seafile GmbH. Seafile GmbH is a business partner of Seafile Ltd. in Germany. They’re not the developer of Seafile project. The termination of this cooperation won’t affect Seafile Ltd.’s ability to develop Seafile and support our customers.

In this statement we’ll explain why this business relationship has to be terminated, with support from facts. We’ll also reveal the infringement actions done by Seafile GmbH recently towards us. Yesterday Seafile GmbH published a statement about stopping cooperate with us. That statement has many places not consistent with the truth. We’ll clarify the confusion they’ve made in that statement.

In this statement, “we” refers to Seafile Ltd. and “they” refers to Seafile GmbH.

History of the Cooperation with Seafile GmbH

Our cooperation with Silja and Alexander Jackson began back in 2014. At that time they ran an IT service company JacksonIT in Germany. They became a reseller of Seafile Pro Edition and provides support to local customers. They also offered to help maintaining a community forum for Seafile in Germany (

After cooperating for about a year, Seafile Ltd. and JacksonIT decided to take a step forward for our business cooperation. Seafile GmbH was founded at January 2015 by Silja and Alexander Jackson. Seafile GmbH was founded with the help from Seafile Ltd., including fund and branding supports. Seafile Ltd. made an investment of 16,000€ into Seafile GmbH as interest-free loan. We also granted them the rights to use Seafile trademark (and use “Seafile” as company name). The purpose of forming Seafile GmbH was to:

  1. Provide local support and better sales procedure to customers in Germany and Europe in general.
  2. Seafile GmbH will run a cloud storage service for German users (now known as

With these investment, Seafile Ltd. didn’t take any equity share from the newly formed company. The rationale was to leave the cloud service completely in German hands so that user’s data can be protected by German laws. Seafile Ltd. will get 70% share from the profit of Seafile GmbH’s businesses.

During 2015, as the business of Seafile GmbH developed, they needed more investment into infrastructure building and hiring employees. We agreed to leave part of our profit shares as fund for Seafile GmbH. We’ve been doing so for 3 quarters, totally about 80,000€. Again this investment was considered as interest-free loan.

At the beginning of 2016, Seafile Ltd. and Seafile GmbH both realized that we have to build a more solid legal foundation for our cooperation. They proposed the following framework:

  • The Pro software sales business of Seafile GmbH will be merged into Seafile Ltd. In exchange we will give shares from Seafile Ltd. to Silja and Alex Jackson.
  • A new company — Seafile Cloud GmbH will be formed to run the cloud service. This company will be completely owned by Silja and Alex Jackson.

But in the negotiation, they asked for an amount of shares that were completely not acceptable for us. The negotiation didn’t end up with a new agreement.

Not reaching agreement in a negotiation is normal in business practices. Seafile GmbH could have ended the cooperation if they’re not satisfied with the result. But they didn’t do that at that time. What they did were to secretly try to gain ownership of the Seafile project, without our notice.

Seafile GmbH’s Infringements to Seafile Ltd.

Since April 2016, we’ve noticed multiple infringement actions from Seafile GmbH towards Seafile Ltd.

First, they registered “seafile” organization on github without noticing us. The contact email and address for this organization are set to Seafile GmbH. And they forked all open source Seafile projects into this organization. This action makes people think that they’re the owner of the Seafile project. This is not allowed in our agreement.

Second, they changed the community forum domain name from “” to “”, without noticing us again. This action turns a community website into their private property. The valuable contents on this forum were created by Seafile developers and the community. Taking ownership of this forum is unethical. In their statement yesterday, they announced removing the account of Seafile team members from the forum. This action further proves that they consider the forum their own property. They have the rights to ban anyone they don’t like on the forum.

Third, they secretly applied for “Seafile” trademark in the United States. The application can be viewed below. This is serious violation to our agreement, which clearly stated that Seafile Ltd. is the trademark owner of Seafile. A screenshot of our agreement is attached below, with Silja Jackson’s signature. Furthermore, they stated their first use date of “Seafile” name in U.S. is 2014.02.14. But at that time they haven’t even started cooperate with us. Their claim has no ground.



Fourth, they refused to transfer the profit shares from Pro software sales  for Q2 2016 to us. After we requested them to stop all the above infringement actions, they silently ignore our request to transfer profit share to us. This is not only violation to our agreement. This is business fraud.

Fifth, they committed copyright infringement to Seafile Pro Edition. Seafile is an open source project release under dual license. The community edition is released under open source licenses. But the Pro Edition copyright is owned by Seafile Ltd. The reason we granted them access to our Pro source code was that: one of our customers — HU Berlin wanted to have access to source code. Because Seafile GmbH was also one party in the contract, we let them provide the source code access to HU Berlin on behalf of us. We didn’t authorize them to do anything other that on our source code. In yesterday’s statement, they announced that they’ll continue developing Pro Edition based on 5.1.8. This is copyright infringement. They have no rights to further develop Pro Edition or distribute it. This behavior is also dangerous to all customers who want to buy software from them.

Counter Statements against Seafile GmbH’s Statements

In their statement: “Instead we will continue to develop Seafile independently in Germany and Europe for the Seafile Professional Edition based on version 5.1.8.”

Our response: This is copyright infringement behavior.

In their statement: “Our cooperation now has reached a point where we can no longer in good conscience develop a software together.”

Our response: As we’ve stated above, it’s obvious that it’s them who pushed our relationship into the current point. And they’re no developer of Seafile project. They’ve never committed a line of code to Seafile’s repositories. Their only “contribution” to Seafile “development” is writing an auto-installation script.

In their statement: “Seafile Ltd. …… disrespect towards data privacy when it comes to German or European law.”

Our response: We haven’t committed any actions that break privacy laws in Germany or Europe. After publishing their statement yesterday, Seafile GmbH deleted all the private data of Seafile Ltd. team members stored on This implies that they think they have the rights to delete anyone’s data on that service if they don’t like them. This is violation of their terms of service. This is also infringement to user’s privacy. Seafile GmbH is not so trustworthy in terms of privacy protection.

In their statement: “Seafile Ltd. revoking our access to the Seafile Professional sources despite it violating contracts with customers. After all the effort we have put into Seafile we see this as the final breach of trust which leaves us no other choice than to part ways with Seafile Ltd.” “Seafile GmbH is obligated to provide our customers with a trustworthy, secure and reliable product. We can no longer guarantee under these circumstances.”

Our response: Given their infringements to our copyright, we’re just going to protect our interest. If a customer of Seafile Pro Edition wants to access the source code, they can get it directly from Seafile Ltd. So revoking Seafile GmbH’s access source code doesn’t affect customers’ trust on Pro Edition.

In their statement: “Our goal at Seafile GmbH is and has always been to provide a stable and reliable product for our customers and the Open Source community.”

Our response: Seafile GmbH has never committed a line of code to Seafile. Their statement about stability and reliability should be doubted.

In their statement: “Price raises during the last 12 month are unacceptable””Raising prices three times within a year (which in some cases meant a price increase of up to 400%) is extremely unprofessional in our opinion and sends a signal of instability and unreliability.”

Our response: We admit that raising price too frequently is not professional. But since we’ve just started commercialize Seafile last year, we didn’t have much experience. At the beginning we tagged an overly low price. With that price we found that we cannot sustain further development. We’ve changed price twice last year (not 3 times in a year). For old customers we all provide them with the old prices or with a discount.  We’ll take this advice and keep the current pricing scheme stable for the long term. Compared to other providers, Seafile’s price is in the fair range. On a side note, Silja and Alex from Seafile GmbH weren’t much against our raise of price. They even suggested higher prices than the current one. Using a decision that they agreed to attack us is not fair.


The statement from Seafile GmbH is full of false arguments and disrespect to Seafile Ltd. With all the helps we’ve given to them, they’re not only ungrateful but also greedy. They’ve committed copyright infringement, business fraud and violation of agreement. Such a business partner shouldn’t be trusted any more, by anyone. We’ve tried hard to reach out to them and negotiate a settlement, but they silently ignore our emails and calls. Their statement yesterday let us make the final decision to terminate the relationship.

The next step we’ll take is to use law to protect our rights.

Such a business decision doesn’t come easily and will have effects to our customers:

  • Seafile Ltd. will honor all the contracts for Pro license sales from Seafile GmbH before 2016.07.22. But since Seafile GmbH is no longer a legal distributor of Seafile software, we request all customers to download Seafile Pro edition from Seafile Ltd.’s channels from now on.
  • The cloud service can no longer run Seafile Pro Edition. However Seafile GmbH can still use the community edition for hosting service. We request them to stop using Pro Edition immediately.

For the community, you can still continue using community edition and getting support from Seafile developers. The only change is we’ll setup and maintain a new community forum (to be named We’ll make sure this forum always be the asset to all community users. A new version 6.0 with many improvements will be released soon.

But there are still some valid opinions in Seafile GmbH’s statement. We’ll certainly improve our release management and avoid road-map changes as long as possible. And we’ll keep our pricing scheme stable for the long term.

  1. Ey, you have some valid points, but, what about the 400% price increase and 3 times within a year?

    to be clear, I don’t use seafile


    1. That’s also not completely true.
      – We raised price twice last year. That was because we tagged an overly low price on Seafile at the beginning. We just started commercialize Seafile last year so we didn’t have much experience. With overly low price we cannot sustain the development cost.
      – They stated that they were against our price raise. But that is not true. They even suggested higher prices.
      We’ll take this advice and keep prices stable for long term. BTW, compared to other provider, our price is not high.


      1. sounds ok. By reading both sides I think SeafileGmbH are wrongdoing.

        Just curious, about patents and IP related topics, why SeafileLtd never bothered to patent and do what SeafileGmbH is doing now to protect themselves?

        About the forum that was a completely dick move from SeafileGmbH.

        I tried and used Seafile in the past and it was working really good, the only thing made me angry was/is that office docs preview is only on pro version which I fixed with Syncthing + local apps.


  2. So what happens to all of the information in the old forum? You had years of solutions and problems stored in there…Is /Will there be a way to port that?
    I’m guessing we will have to register on the new forum…

    1. We’re sorry but there is no way for us to export data from the old forum. Our accounts are deleted already. But we’ll try to copy some useful tips from that forum to the new forum.
      Yes, users have to register on the new forum.


  3. Your explanation of the current events sounds more reasonable than the one of the GmbH. They made some shitty moves. I think I’ll stick with you (and I’m from Germany).


  4. Hi Daniel,

    thanks for your statement, I was very suspicious about the post by Seafile GmbH yesterday, everything seemed very dubious. Your clear statement confirmed this assumtion. I’m sorry that you are involved in such a stupid conflict, the one that are hit at most are your customers. But actually I’m happy that we’ve just bought our Pro licence from you, not from them.

    What about the trademark “Seafile” (Name, Logo)? Are you going to protect it? Your customers will be very puzzled about two companies with the same name and product in the future.

    And please answer me another question: Alexander stated in the german forum that you lost interest in the project and are about to leave development soon. Multiple developers left your project and your side projects (like the mobile apps) are not really developed or maintained anymore. Is this true? How are your actual plans regarding the future of Seafile?

    1. tvollstaedt, Thank you for understanding!

      We’ll use legal way to protect our trademark. It’s illegal for them to use our trademark too after the termination.

      That’s a misunderstanding from their side. We’ve never expressed lost of interest in Seafile. We’ve discussed about pursuing even more challenging goals after Seafile becomes a successful business, which is perfectly normal from my point of view. That doesn’t mean we’ll stop working on Seafile in the future. Seafile project will be maintained and developed for the long term. Our development team has been quite stable for the last 1-2 years. Like many companies, employees coming and going is normal. Now we have more than 10 developers. The Andriod and iOS clients are still maintained and developed, by our employees and by some community members. If you look at our change log, you’ll know what they said is not true:


      1. I was really baffled to just see that the development of at least the Android client ist constantly being take of, while Seafile GmbH states there is not a single developer caring for the apps. That is obviously not true. And the Android client works well for me, too.


  5. I’m from germany and I am using the Seafile community edition for about 2 years now I think. I’m kinda shocked to read those statements from Seafile GmbH and then the response from Seafile Ldt.

    The point is that whenever I had a problem it was one of the chinese team who gave me support (mostly daniel). The Jacksons did never give any useful information to solve problems or so. Although I’m totally thankful that they ran the community forum, which was absolutely helpful. It is a shame that all the Info there could be lost or so, as I will stick to your original seafile software. I just hope that you sue them somehow for what they did with this fraud to seafiles reputation. It is simply a absolutely great piece of software that I can’t replace with something else! So please keep your heads up and permit them (by law) to use your code for their business!

    We in germany usually think that the law is quite clear in terms of copyright and so on, but still there are people who just give misinformations to strentghen their interests and this shall never end in their favor!

    Best regards from Bremen

    1. I fully agree with your post. The software and your community support where really brilliant in the last two years. I am also using the communiy edition and a few issues in the past. Each and every topic got an immediate valuable answer by chinese developers… Thats much more than anyone could expect from a free software. At least your community work shows that the team us really committed to its product!

      So, what I can see currently I will stick with Seafile Ltd. Thanks and keep up your really good work!

  6. I’m glad I read this. The email I received from GmbH was really vague, rushed and obviously emotional. Your response, if true highlights the actual relationship, roles and breakdown. It sounds like they feel like the built the community and want more of a share. It also sounds like they ‘sold’ it, but didn’t ‘build’ it. I hope the truth comes out and whoever is entitled to what is resolved. I also hope that one or the other (I think the other) has everything removed so users are not confused as to what is going on.


  7. You’re both a bunch of immature, imbecile persons running companies that now go to war.

    With real FOSS this’d never happened. Sure, there would be a fork, but at least there woudn’t be idiots pointing at each other for reasons only they really know.

    Oh, and btw, that trademark agreement you signed: I’d say, you’re fucked because you signed away your rights. 🙂


      1. Oh, so it’s rude to tell, how it is? Maybe next time you tell someone they’re rude, you consider the circumstances. Two companies who have customers they should care for instead invest time in such childish behaviour. THAT is rude.


        1. It was our fault to trust them too easily. Thank you for your suggestions. We’ll use law to protect our rights.
          We’ve tried our best to negotiate with them. But it was them made this conflict open. We have no choice but to defeat their false arguments.
          Since we’ll honor all contracts signed by Seafile GmbH, we’ll make the impacts to customers as small as possible.


    1. I agree with the sentiment – just said as much myself below (though you may want to try expressing your views in a less offensive manner).


  8. I had purchased my Pro license from (Seafile Ltd) a while ago but the email confirmations back then contained links (download, support, forum etc) to the .de domain instead of .com domain. The Pro download link (.de) now asks me to register. That’s ridiculous.

    Where can I download the Pro version from Seafile Ltd?

    Can you please email all your paying customers like myself with a set of links to the download, documentation and support? Right now the German website looks more professional.

    As for the split between the two companies: to me it feels like both parties are contributing to making paying customers feel uneasy. Both your and their posts reveal internal details that make your companies look unattractive. It’s quite unprofessional.

    I’m certainly much more concerned now than I was before, and as a paying customer I feel it’s all very chaotic … I receive emails from .de but apparently I have my license from .com, yet .com doesn’t communicate with me.


  9. Guys,
    you are great! I love both the server and client-software of seafile!

    I will stay loyal to your code-base!

    Greetings from germany!


  10. Hello Guys,

    Thats very bad news i am reading here.
    are you also planning to offer a similar service to
    i am feeling strange now using it when i am knowing that there seems to be something wrong with it there.
