Levaté Work Log: August 13-August 22

The team is back from their vacations, and has returned to their hard work!

Here's what we'll be focusing on over the next week and a half:

  1. Can we build a prototype that someone can wheel around with, deploy and undeploy, that lifts a full 12 inches and full 330 lb? This will include 3D printing a shell, since welding an aluminum shell didn't work.
  2. What size base is necessary to create a completely stable lifting experience for the user?
  3. Can we submit 2 grant applications that open up on August 25th to secure funding for Levate?
  4. Can we begin the process to purchase liability insurance, and at least get a reasonable quote and find a company that would be willing to cover us once we have the beta-units built?
  5. What does the FDA approval process look like? Can we submit FDA approval paperwork now? When would we need to submit, how long does it take, and what would we need?
  6. Can we sign the licensing agreement with the University of Oklahoma? Though we invented the device, it is considered OU property since we invented the device through a University program.

Feel free to reach out if you think you can help us answer or solve any of these questions!

Until next time,

Dillon Dakota Carroll, CEO

The accelerator wraps up, and Levaté gets a new team member!

It has been a while since the Levaté team has posted an update on our blog! If it's any consolation, while we've been hard at work it also hasn't been terribly interesting work. We wrapped up the summer Sooner Launch Pad accelerator program we were involved in and have been taking a brief hiatus since then- both Ethan and Dillon had weddings to attend, which is also a natural excuse for a bit of a vacation!

We'd also like to welcome Andrew Stewart onto the Levaté team! Andrew just graduated with a degree in Industrial Engineering and is working for Northrop Grumman in Oklahoma City. He was part of the inaugural Levaté intern team that invented the lift during the Spring 2014 semester, but was unable to continue working on it as he already had his job lined up. However, he happily has joined the startup team as the Levaté Social Media Manager! So all the great content you see coming out of Levaté's Facebook page and Twitter account is thanks to him. He's barely been on the job for a week and we already have over 100 twitter followers, which is fantastic. Welcome to Levaté LLC, Andrew!

If you haven't seen Dillon discussing some of the lessons learned from the new company's 10 weeks in the summer accelerator program, you can take a look at the video here. It's a good recap of the big gains we were able to make over the course of the summer.

Looking forward from here, the big focus for us will be on moving forward the building of Levaté. We were hoping to have a new prototype up and running for our end-of-the-accelerator presentation. Well, that didn't go according to plan exactly. Ethan, our CTO, made a heroic attempt to get it ready in time. He had welded together what should have been a fantastic telescoping aluminum support structure that would house the pneumatic cylinders and also provide a stable base for the lift. What we weren't expecting was that welding the aluminum tubes would warp them slightly and keep them from telescoping properly!

It is sobering for us to know that we still have a lot of work to get done before Levaté can be in the hands of users, restoring their reach. From the enthusiastic response from the wheelchair community we know that this is a device that will help tens of thousands of people across the United States. Now we are faced with the difficult task of delivering on the vision we've developed over the past 7 months.

One possibility we're considering is working with an engineering consulting or design firm to accelerate the product development. We have a conversation scheduled for the week after next (once the entire team is back from vacations and weddings) with a possible partner. The idea here is that we would work with the design firm, describing exactly what Levaté needs to be able to do. Working within the constraints we provide and using concepts communicated by the prototypes and drawings we've made of the lift thus far, they could bring decades of industry experience to bear and build a fully-functioning prototype in a fraction of the time it would take us, as recent college graduates. They would also potentially deliver the engineering drawings necessary to take the lift to a manufacturer and get them built! So you can understand why we're intrigued by this possibility. We are not sure what the cost would look like for a service such as this, but I don't doubt that it will be fairly significant. It is a tradeoff we'll be considering a lot over the next few weeks. And if you know of any resources we might be able to turn to- engineering expertise with pneumatics and the like- please don't hesitate to let us know! We'd love to chat with a friend or a contact if you think it would be useful for us.

Look back here for another update in a week's time or so. Until then, enjoy the weekend and take care!

PS: As a bonus, here's a video of the accelerator crew (4/5 teams that were launching businesses) meeting on Thursday, July 30th to hold each other accountable. We each spend a minute or two covering what we've accomplished in the past week, and what we'll be working on in the next two weeks before our next "biweekly" accountability check-in. Levaté goes last in the video in case you want to skip forward to us.

Tests for the week of July 8th

Test 1: Can we build a prototype that is mobile, lifts 300+ lbs and a full 12 inches, and can we have a wheelchair user test it?

Test 2: Can we make progress on funding? This includes submitting an SBIR grant proposal, as well as getting meetings/executing on next steps with 3 potential funding contacts we have.

Test 3: Can we make a short video comprised of prototyping footage and customer interviews that we could use for a kickstarter campaign?

Tests for next week: Social Media, VA, and Prototyping

What's up everyone! I hope you're all enjoying the world cup USA-Germany match right now.

Quick update on what the team's working on over the next week.

1. Can we get just as much user activity from social media content as we did with our facebook ads in 1 week time? That means getting about 10 beta test users and 10 newsletter subscribers to sign up on this website.

2. Can we get our wheelchair lift into the VA hospital computer system and have a veteran request one of their OT or PT? This is to understand the process for when we are manufacturing the final version of the wheelchair lift and are trying to get it in the hands of wheelchair users.

3. Can we have a wheelchair user test a working prototype, and get feedback from them on it? Obviously, this will be huge for us.

Those are our tests for this week. Go USA- We believe that we will win!

Facebook Ads and Delayed Cylinders

It's been a whirlwind week! We've been on the phone with customer service reps trying to locate lost pneumatic cylinders, learning the basics of digital marketing and online ads, and also making plenty of phone calls trying to understand more about the insurance reimbursement process for wheelchair accessories.


Levaté is Mobile

There is some good news to report on the prototyping! Take a look at the pictures below of Ethan operating the lift with 125lbs of weight on top. It's using small pneumatic cylinders of 0.5 inch diameter that can support less weight but are cheap and quick to prototype with. Also, notice that the lift is connected to an air tank- a paintball air tank actually- so the lift is mobile as well!

Today and tomorrow we'll be working on using the new, thicker cylinders we just bought to build a prototype that can lift our full 300lb. goal.

That part of the prototyping was a bit delayed, unfortunately. We overnight ordered two 2.5 inch bore, 6 inch stroke pneumatic cylinders. They should have arrived last Thursday morning. The package finally came in on Friday, but with only 1 cylinder! A call to customer service confirmed that a mistake had been made in their shipping, and we received the second cylinder on Saturday. It set our prototyping back a few days, though I will say that Sherry, the woman we spoke to at the Industrial Supply store who was managing our order, was incredibly helpful and apologetic throughout the entire process.

Facebook Advertisements

Last week, we signed up to run a series of four facebook ads to understand 1) what sort of engagement and response could we expect from such ads; and 2) what content in the facebook ads would be most effective. After four days of ads, a reach of 17,000 facebook users, and $70 total spent, we have some interesting results.

For the sake of semplicity, let's say we had 2 ads, with written messages (limited to about 150 characters), codenamed ads 1 & 2.

When a facebook user saw ad 1, they either saw picture A or B, but not both. Ad 2 on the other hand, demonstrated either picture B or picture C to users. This way, we could tell not only which ad text message was more effective by comparing the engagement results across picture B, but also which pictures were more effective, by comparing specifically those within the Ad 1 and Ad 2 messages.

Here are the results:

  1. Ad message 1 with picture A had 39 website clicks and 10 post likes, with a click-through rate of 3.3%. The click through rate is how many people out of a hundred actually clicked on the ad. It reached 1400 people.
  2. Ad message 1 with picture B had 10 likes, 2 shares, and 24 clicks, and had a click-through rate of 2.3%. It reached about 2000 people.
  3. Ad message 2 with picture B had 21 clicks, 7 likes, and 2 shares, with a click-through rate of 0.8%. It reached 2300 people.
  4. Ad message 2 with picture C has 198 clicks, 23 likes and 8 shares, but only had a click-through rate of 1% because of its very high reach (12,000).

These results indicate that Ad message 1 is clearly superior to 2, and that picture A is superior to B & C. Here was the winning ad:

Insurance Industry Hassles

That just leaves the last of our tests this week to talk about, The Insurance Question, or: Can Levaté be insurance reimbursable? We had heard anecdotal evidence that power lift devices might be considered medically necessary by insurance if they were instrumental in helping the user transfer in and out of their power chair, for example. Our thoughts are that we could make a similar argument for Levaté, and we wanted to talk to a decision maker in the industry to confirm this and understand what process a wheelchair user would need to go through to get a Levaté unit reimbursed by their insurance company.

First, the good news! It looks like the process for registering a product with the Veteran's Administration (VA) is very straightforward: you go to sam.gov and complete a registration process there for the device. Once it's registered, the VA will pay for 100% of the device. The only hard part after that is generating the word-of-mouth among wheelchair users and PTs: The former so that they ask their PTs for them, and the latter so that they recommend Levaté to their patients. If a purchase is under $3,000, then it's approved immediately by the local VA hospital with a minimum of red tape.

On the other hand, it looks like both manufacturers and wheelchair users are opting out of medical reimbursement entirely.

One wheelchair accessory manufacturer explained why they opted out of trying to get their device (the FreeWheel) coded by insurance companies. The fee you pay Medicare- who sets the trends for the entire industry- is $50,000 just to begin the coding process. And there's no guarantee that the insurance code will be approved. Even if it is, you pay $8,000 annually to maintain the code and insurance providers can still deny a claim for that code if they feel there's a reason to (ie if they can save money and get away with it).

Wheelchair users are also opting out of insurance due to the hassle and 6-12 month wait. That means that a wheelchair user with a chair that's falling apart could wait up to a year from the time they file their insurance paperwork before they get their new chair, as was the case for one of the wheelchair users we spoke with a couple days ago.

Scott at Tri State Medical, a wheelchair dealer, noted that 30-40% of his customers opt out of trying to get insurance to reimburse their purchases and instead pay for their new wheelchairs out of pocket. This is even more so the case for purchases under $1,000. At $500, he said most wheelchair users won't even bother trying to get a device reimbursed by their insurance- it's just not worth it.

Clearly there are some things very wrong with the American insurance system. Until there is industry-wide reform, we can at least equip wheelchair users with the tools they need to try for insurance reimbursement of Levaté with their private insurance. Freewheel, which I mentioned above, provides instructions for wheelchair users on their website to get their doctors or PTs to prescribe their accessory in such a way that it is seen as a medical necessity and can be covered under the "Miscellaneous Wheelchair Accessory" code K0108. This may be the best workaround for those who have private insurance and can't afford Levaté on their own.


That's what the Levaté team has been up to this past week. If you have any experience with the insurance industry or reimbursement process and would like to comment on the process or what we've found so far, we'd love to hear from you! You can comment here, send an email to levatelift@gmail.com or find us on facebook and twitter.

Up next: Prototypes, Insurance, and Web Traffic

At the Sooner Launch Pad Accelerator, we're operating on "sprints" or iterations of 1 week. In other words, each week we choose 1-3 hypotheses about our business that we want to test.

Here are the three that Levaté is working on over the next week:

1. Can we build a Levaté prototype unit that a wheelchair user could use in their day to day life? That includes being portable and having a self-contained air supply, achieving a full 12 inch lift, and being able to deploy/undeploy completely.

2. Could Levaté be reimbursed by insurance under any circumstance? We'll be testing it by interviewing at least 5 decision makers in the insurance industry. If anyone has a connection to Medicare, a private insurance company, or a friend who's been reimbursed for a power wheelchair with lift, that would be a big help for us!

3. Are online ads through facebook and google effective ways to raise awareness of Levaté and drive traffic to this website? We'll be meeting later today with Eric Morrow to talk about the specifics of digital marketing and how this could apply to Levaté. Should be informative!

That's what we'll be up to for the next week. Stay tuned for the results of our work!

Welcome to our new website!

Hi everyone! Welcome to our new website for Levaté. We hope you enjoy it. Of course, it's a work in progress, so feel free to shoot us an email (levatelift@gmail.com) with any comments, suggestions, or questions you have. This is the first website either of us (Ethan and Dillon) have made, but thankfully SquareSpace, our website building and hosting service, makes the process pretty easy.

Our plan is to use this part of the site to post more or less weekly updates on our progress. That should do two things. First, it will show you the progress we're making. Second, it will help keep us accountable! There were three big things we worked on in the past couple weeks: building a prototype in the OU machine shop, attending the endeavor games and networking with wheelchair users, and meeting with i2E in Oklahoma City to initiate the funding process.

So now, for the exciting part: the prototyping! The bulk of our machine shop work this past week went towards building a rough prototype that had a working pneumatic cylinder. By working, I mean to say that it lifted 200-300 lbs of weight (chair included) a full 12 inches off the ground. Unfortunately the air compressor we're using only reaches about 100 psi, and we need air pressure of about 150 psi for it to lift any substantial weight. The video below has more details:

Our next step is to find a compressed air tank that has the required pressure so that we can test it with weight on the chair. Though, we certainly had a "blast" welding this prototype together!

The welded pneumatic cylinders. Surprising lightweight- they weigh less that 2 lbs combined. Notice how they actuate in opposite directions to gain double the lift of a single cylinder.

In the next day or two, we'll have more to report on the pneumatic cylinder after we find a suitable compressed air tank. Likely we'll just use a paintball gun type tank- the kind that's compressed up to 4500 psi or more.

In the meantime, we're also exploring the possibility of using a hydraulic cylinder (hydraulic = liquid, pneumatic = air) powered by a small motor. The advantages of this is that it could potentially lift more weight more easily, while also being easy to recharge. Everyone has a wall outlet, after all, whereas air compressors are less common. We'll have more to report on this in the next couple of days as well- Ethan has been spending many an hour visiting industrial supply shops to find the specific kind of cylinders we need.


We had the opportunity to attend the Endeavor Games on Friday, which Ethan and I loved. Everyone we spoke to there was kind, had a great attitude, and was willing to speak with us for a few minutes as we talked to them about Levaté. A lot of the wheelchair users we spoke with signed up to beta-test the lift, and we also got some great feedback.

For example, we hadn't thought too much about how much clearance Levaté would have to have off the ground when it's undeployed underneath the wheelchair. Jeremy, a canoe paddler aiming for the gold in Brazil, 2016, explained that he will often pop wheelies over small obstacles so that he doesn't have to go around them. For our lift to integrate seamlessly into the routine of someone like Jeremy, we couldn't risk having it clip or hit the ground while the user is performing such a maneuver.

The other interesting feedback we heard makes us want to reinvestigate whether or not Levaté could be covered by insurance. It's our understanding that the vast majority of aftermarket accessories for wheelchairs are not insurance reimbursable. We heard from a couple wheelchair users in the past few weeks that they obtained power wheelchairs with lifts via insurance, as their provider judged that they were medically necessary to effectively transfer. Over the next week, I'd like to investigate whether we could make a similar argument: that Levaté could greatly improve the way manual wheelchair users transfer. It may come to naught, but it's a lead we should run down, since obtaining insurance reimbursement would be huge for us.


Finally, we met with i2E in Oklahoma City to begin the funding process. It's an exciting milestone to have reached the stage where outside investors are considering Levaté! We filled out a reasonable amount of paperwork, and we've done all we can for now. The investment officer at i2E that is managing us as a client will have to pitch us to i2E's investment committee, which is only phase one of a funding process that will take at least 2 months (and likely longer). Receiving the funding may take a while, but it will help us scale our prototyping so that we can manufacture enough to have a sizable beta-test and collect plenty of feedback and insights into how our product works in the real world.


As you can see, it's been a busy past couple weeks! Looking ahead, Ethan and I have quite a bit of work to do to move the prototyping forward. Right now, we're focusing on getting a working pneumatic or hydraulic cylinder. Then, we'll move on to the other components of Levaté.

I also want to chase that insurance question down- that is, whether or not there is a decent chance that the lift could be insurance reimbursable under certain circumstances.

Hopefully you've enjoyed the look into what the Levaté team is working on! As always, feel free to contact us (levatelift@gmail.com) with any questions or comments.
