One of my favorite demos at Disrupt NYC was from an education startup called Desmos that is reinventing the whiteboard to make it browser-based and interactive (watch their Disrupt video below).

One of the killer features of the Desmos Whiteboard is an interactive calculator that graphs equations as you write them. (Founder Eli Luberoff was a double math and physics major at Yale). Desmos has now taken that and rewritten it as a standalone online graphing calculator. It instantly draws the equations as you update them, it’s free, browser-based, color-coded, and you can share any graph with a bitly link.

You will never have to buy a Texas Instruments calculator again (do they still make those?)

Desmos closed an $800,000 seed round the day before Disrupt NYC from Mitch Kapor, Learn Capital, and Kindler Capital.

very warm welcome when they come on. It's really hard to be up here and pitch a business. For some of the companies, this is the biggest pitch of their company so far. So do give them a very warm welcome when they come on. Let's welcome to the stage from SHL TeleMedicine, Shay Leibovitz and the VP of business movement and sales and Iki Alroy, the CTO.

No? Wait. Eric is, it 's already been disrupted. What's happening? Well, why is...? Oh. Ok. Let's do that all over again. Let's pretend none of that happened. Apparently, we are just randomizing the order, so that maybe next time I just won't announce the name, we can just guess, when they come on, who they are.

So, in that case, please welcome to the stage from Desmos, Eli Luberoff, the founder and CEO, and Andrew Gu, the CTO.

Which one?

It's a session four.

Session four.

There's only one, two, three.

Thank you so much, so I'm Eli Luberoff, founder and CEO of Desmos, thanks for switching the order. I'm here to tell you about the future of education. I am joined here on stage by Andrew Gu, our CTO who couldn't be here yesterday, because he was busy graduating, and by one of my favorite toys. This is an interactive touch screen, and I just want to show you what this can do.

These are taking over classrooms in this country. More than a quarter of United States classrooms have one of these in them. And what it is, is a regular projector that you can touch and interact with.

So I just want to show you this, you can drag things around, really, really cool taking over this country. But, there's a huge problem, which is that there are a lot of different companies manufacturing these, and every single one of them has a different piece of software for building interactive content.

That means your content is locked not only into your platform, but it's locked into the classroom. You can't access it from home. Teachers can't access it from home. We have a solution.

So I want to show you this exact same lesson built in our software. So here it looks exactly the same, but what you will notice is this is now completely browser based. It is inside the Safari browser. This means two things: one it means it works on any device that has a browser; the other, it means that multiple people can interact with this content simultaneously.

So, Andrew, why don't you do the same thing and drag out a label. Fantastic, and we actually have Greg, another person from our company in the audience on a PlayBook and he can drag something as well, and we'll be able to see it up here. So you can see him dragging it from his PlayBook. No special installed software.

Did everyone see that? Really, really cool. So let's go to page two of this. Check our answers. It turns out that we didn't do very well. Let's go to page three. What we have here is just an example of anther type of lesson that you can do. So, this is geography. Andrew, why don't you tell us which state has a capital of Olympia.

This is actually your home state, and there it is. And Greg, can you tell us which state has the longest coastline? Again, from the audience, on his PlayBook, dragging this out. No installed software, all browser based. Alright, so let's go to page four. What we have done is we have managed to replicate downloadable software and put it in-browser.

I don't think this is a crowd where I need to tell you why and that's awesome. But, that's not enough for us. We wanted to solve other problems in education. So one that is most frustrating to me, as a math and physics major, is that it's really hard to do math on a computer. No longer. Andrew, I want to you take our equation tool and write out the equation for a parabola.

So he's just gonna type this out. It's gonna auto-format. This is a functioning calculator. Take out the graph paper, drag out a graph, and now take that equation and drop it on top of the graph paper and it's gonna process it. I want you to take that equation and modify it. Let's move it 2 units to the right and 3 units down .

Here you can see the graph updating as you change the equation. A totally new way of interacting with math. I'm a total math nerd. I know not all of you are. I'm gonna leave that there except for questions. I just wanted to say, Texas Instruments, your monopoly on graphing in the classroom is over.

Alright. Thank you. This is a lesson we were able to collaborate with Greg, but now I want to share this the world, and the way that you do that is with our publish feature which we're introducing today. So if you press this publish button, what it's going to do is process these pages and we're going to see, if you go over to the second tab now, the final result of that is here, where it's made thumbnails of each page.

You can give it a title, you can give it a description. You press submit, and it's going to now be a fully published, accessible lesson. So, if we go over here, this is the exact same lesson but it's now totally different in that a million people can look at this simultaneously interactive, they each have a local copy that they can work with.

We have embed code for this so you can share it on a learning management system or in a blog. You can link to this. You can view it as a PDF. You can even download an offline version of this that doesn't require you be connected to the internet so that it can be used in classrooms. So this is what we were able to do with our software, I want to show you what a professional is able to do.

So, this is actually the first time this lesson has been seen. It was built by New England typographic services from McGraw-Hill. And let's close that. And this is a beautiful lesson that they did using just our tools, building it in ours instead of a native piece of software. So click on the Explorer and here you are going to see we've embedded a video.

Let's go down to the apply, and here we have got all sorts of interactivity. You can imagine touching this. You can do it in browser. So, let's see what clue one for word A is. All right, there's clue 4. Soil, you can click. It's interacting, this is truly interactive content. So I want to leave that there.

But I have two really important announcements to make.

So the first is, as of last Friday, we are funded. We have $800,000 financing led by Mitch Kapoor, followed by Learn Capital and Kindler Capital, we're incredibly happy about that. And what we're gonna do is make this even better.

The second announcement is that as of right now, you can register for our site for the Alpha version. You need the code TCDISRUPT. We've launched. 500 people can do this and I am going to leave that there. I hope that you will join us and changing the future of education. Thanks.

That was Desmos. That was, day two is going to be a good day, I think. Also I went to school in the wrong decade. That was cool. Tony. Thoughts and questions? Nothing?

Not yet.

You can't pass on to Chris. Alright, Chris.

Yeah, so first of all, that's totally rad. I'm curious, what's the rate of adoption in schools these days, and what's the channel to get there? I mean, so, you've built this really cool tool, it's browser based, so there isn't really a deep software commitment on behalf of schools, but how do you get to the decision makers there?

That's an excellent question. So these, the boards have infiltrated 25% of schools here, 80% in the UK. But right now they are not really being used to their full potential. They are mostly being used is dry erase boards that are really expensive, or overheard projectors that are just a little bit expensive.

How do we get to them? So we're actually trying to bottom up approach on one side, which is why we're going to launch for all teachers as soon as we 're out of our testing period.

But the others that were working with are publishers, who've already invested a ton of resources into this kind of content. They had 400 million dollars in revenue last year, small fraction of their revenue for the top four publishers, but 400 million dollars in revenue from interactive content and they love this.

The reason is that they can build a lesson once and get it to all teachers instead of having to build it three, four or eight times.

I just wondered, who are the four public, who are the four big educational publishers that you are talking to?

So, McGraw-Hill, Houghton Mifflin Harcourt, Pearson, and Cengage are the big four. We have actually pilot projects with all four of them.

OK, great.

Yeah . I mean it kind of reminded me of the first time I saw OddPost actually with this like beautiful javascript and AJAX stuff.   It reminded me of the first time I saw Tony's company and so I thought that was beautiful. It just seems like a lot of different applications. I mean, I don't know if you're focused on one thing or if it's a portfolio of products.

You know, tell me more about the actual products that you're launching. Is it all of these things?

So, which things are you talking about?

I mean are you launching a whole portfolio of products or is it a general purpose tool?

It 's a general purpose tool. So, we want this to be a platform on which other people can build content. We'll do it too, publishers will do it as well. But it's just a platform for building any subjects. So, I'm really good at building math lessons, but there are other people who're great at building history lessons.

We want them to be able to build using this as well. And it's basically two applications for launching which is the collaborative version, the whiteboard that you saw, and then also this published version that you can then embed across the web.

I had a question about social collaboration. So I watch my own children and the way that they like to do homework together.

Yep.

So how does that tool facilitate that?

So, this tool is fantastic for it. The application built around it is not ready for that yet. So one thing that we didn't show you is that if you create a whiteboard, which any student could but I doubt many will at the beginning. Once you build this whiteboard, you can then invite anyone to collaborate on it with you by emailing.

So that's what we did with Greg and the audience.

Was that the question?

I think that's your most critical hook.

I agree completely, I agree completely. This is the alpha launch. As I said we raised $100,000 up until last Friday, $800 ,000 last Friday, so when we come back next year it's gonna be nine times as awesome if I know my math.

Awesome. Any more questions for them? Wow, okay short Q&A. Everyone seems impressed. That's Desmos. Big round of applause for that.

Alright, couple of quick bits of housekeeping. Does anyone want some water? I have water here . Everyone good? Yeah. Also we are aware that there's
