00:06 Host: Welcome to your podcast and YouTube blog covering your German startup scene with news, interviews and live events.

00:19 Joe: Hello and welcome, everybody, this is Joe from your startup podcast and YouTube blog from Germany. I’m here at the Frankfurt Book Fair and do have another startup from the Content Shift Accelerator program here with me. Hi, welcome to Torsten.

00:34 Torsten: Hello

00:37 Joe: And you are from the startup?

00:39 Torsten: We are from mindzip.

00:42 Joe: And before, we talked, you told me like mindzip is something like Instagram for brilliant ideas, I actually like this phrase not only since you’re based in Frankfurt. So, tell us a little bit about this idea.

 mindzip is like Instagram for brilliant ideas

00:57 Torsten: Yeah, mindzip helps you to remember everything that you have learned, and you can make structure study notes while you learn something. And later on, our system organizes all your notes that you have taken, and our study coach optimizes a daily agenda for you and with 5 minutes of a day you can internalize up to 20 books per year. But you don’t need to do all the study notes for yourself you can even subscribe from other people. So, we are a community of people, micro-communities of like-minded people around certain questions and books or any source of knowledge. We help you to organize knowledge, your key takeaways, in an efficient way. Because currently, if you save study notes you can do this in any note-taking app, on paper, in an eBook reader, but what is the lifecycle of the study notes there? You write them down and most likely you don’t look at them again, but we make something meaningful out of it to internalize it efficiently and to share with other people.

02:12 Joe: So, you’re replacing the posted notes you write everywhere with a social network where you can share or not share your content in a digital way, right?

02:25 Torsten: Yes.

02:27 Joe: That is pretty cool, and I’ve seen when you showed me the app, it’s basically an app on a cell phone. Before we started with the interview you showed me you’ve prepared for your startup pitch with this, how do you do that?

02:42 Torsten: Right, we have various use cases and one use case is to prepare a pitch. You upload your pitch deck in our web editor and then you can add each slide the text, your key thoughts that you want to say in the pitch. And we help you to optimize your pitch, the wording and we calculate how long the pitch takes and you try the pitch with the app because it’s internalization as well. And on top of that, you can share this in a closed user group, with your investors or any other stakeholders and that’s a new way to improve pitches and to share ideas with anybody.

03:30 Joe: That is actually a very nice applicable idea for our audience and I have a question, how is your outlook? What are you planning to do like in the next year or next time?

03:44 Torsten: We have a lot of use cases like this specific version for startups. But in general, we want to structure knowledge and we want to help the world to show different perspectives on how books or any source where knowledge is saved can be seen. So, if three people read a book, they have different ideas about the content in the book and in our system, we can bring all these together and show different perspectives and our users can do this in an easy way to connect single thoughts and make something great, like a multi-layer mind map. So, our community will create in the near future a new reference system for the world’s knowledge. So, this will totally change the world of learning and how we discover books because isn’t it interesting to know how many times a specific quote from Berta is used in what books and what language. Currently, there’s no system where you can see this. This will be possible with mindzip and you have many use cases out of that, so we will become something like Wikipedia for compressed knowledge. And the biggest challenge was to make it easy because knowledge, this topic that we are working on is complex and we try to make it as easy as Spotify, you subscribe to single thoughts or collections of thoughts and you just repeat and study what’s interesting for you like you listen to playlists in Spotify.

if three people read a book, they have different ideas about the content in the book and in our system, we can bring all these together

05:34 Joe: That is pretty good. If you just take one step back, you can see the Content Shift and how did you profit from this accelerator program? How did it help you? What did you achieve with this program?

05:51 Torsten: First of all, we got in contact with interesting people out of the industry and they pushed us to structure our whole use cases and our user base in a new way. So, we started working intensively with personas and we defined one persona, we call him Leonardo. These are people that create their own study notes if they study something because they want to repeat that because they know they forget up to 70 percent within the first week, and if they repeat, they have an efficient way to internalize everything. And we found out through Content Shift that we have a lot of these Leonardo’s, and if they find us, they write us love letters because we solved a significant problem in their life. All the study notes that they have taken before now they get meaningful and they get organized in one place and they understand that if you zip what you have learned, with mindzip you have a place to unzip it when you need it in real life and the best part is you can internalize it quickly. So, Content Shift pushed us in that direction and currently, we have 120000 users around the world and we identified with a lot of them and we are now focusing on these kinds of users because they really appreciate what we’re doing.

07:24 Joe: Great. Well, best of luck and thank you very much.

07:27 Torsten: Thank you.
