Context:

I joined Roam in 2016. I was the 9th employee and the first team member hired to think about the commercialization of Roam’s patent soft robotic technology. Their pneumatic-powered actuators had a 10X strength-to-weight ratio compared to electric motors at one-tenth the cost.

Goal:

My goal was to turn their technology into a viable product. I had 9 months of runway to create a compelling business case so we could raise series A funding. One year after that to have a limited product release.

Phase 1: Product Discovery

Activities:

  • Understand engineering constraints

  • Look at the technology's strengths and weaknesses to identify use cases.

  • Conduct broad user research (qual and quant) to identify user groups and market segments.

  • Create a business case for each user group and market segment.

  • Use the above constraints to create a short list of viable products.

Engineering Constraints:

Pros:

  • Lightweight Actuation: actuator made of cloth only

  • Power: Overall 10X strength-to-weight ratio when compared to other exoskeletons

    Price: Likely $500 manufacturing cost, $2K price tag

Cons:

  • Size and Weight: large actuator and requires a battery and air compressor located on the body

  • Sound: The air compressor makes some noise.

  • Actuation Precision: The Acctuator can add power to join but can’t control the position

User Group 1: Medical/Injury Recovery

Conditions Explored: Recovery after knee replacement, Osteoarthritis, Rheumatoid Arthritis, In-home Nursing Assist

Research: Conducted qualitative user interviews and prototype tests with each user group and the medical professionals that support them.

User Assessment: It reduces pain in joints while using and reduces the risk of re-injury.

Assessment: Medium-sized TAM, 2K price is not a problem; it’s the same as top knee braces. Product aesthetics in public are an issue. The ability to put on and take off the device is an issue.

User Group 2: Sport/Aging Athletes

Activities explored: Ski Assist, Hiking Assist, Running Assist, Motorbiking.

Research: Conducted qualitative user interviews and prototype tests with each user group and quantitative market tests through Instagram and Facebook.

User Assessment: It reduces joint pain while in use and can significantly extend activity length. However, product aesthetics are a big problem for users.

Assessment: Medium Sized TAM Price is acceptable only for the ski market because of the high baseline cost of activity.

User Group 3: Military

Activities explored: Hiking with a heavy backpack, running over long distances, and traveling through very rough terrain.

Research: Conducted prototype test with the military officer through the DARPA program.

User Assessment: It reduces pain in joints while using and can significantly extend activity length.

Assessment: Large-Sized TAM, Price is acceptable, (note: military purchase patterners are not compatible with startup funding constraints.)

Conclusion:

With guidance from our investor and full team support, we moved our Ski assist, Military Hiking Assist, and Knee arthritis rehab concepts into product development.

Timing: 1 year: Q2, 2016 - Q2,2017

Phase 2: Product Development

Activities:

  • Create user-specific functional prototypes with engineering mass production limitations considered.

  • Run limited product pilot in market segments to quantify value proposition & MVP features.

  • Learn, iterate design and business cases, then pick one market segment to pursue first.

Pilot Group 1: Knee Injury Recovery

We worked with a Stanford University medical professor and knee surgeon to run a study to determine the efficacy of Roam’s robotic knee brace. We also worked to determine the overall business plan. Results:

  • Those using our exoskeleton recovered with more mobility and less perceived pain than those without.

  • SAM for Rehab is $500M

  • SAM for Home Mobility $10B

Next Steps: Pursue potential insurance subsidy as a knee brace, which would cover up to $2k of the device cost.

Pilot Group 2: Aging Athletes - Skiing

We rented a small space at Palisades Tahoe and did a one-day rental of knee braces. We also ran a marketing campaign on Facebook. The pilot was ongoing when I left, but in the first few weeks, we estimated the following results:

  • Rentals were popular among those trying to ski despite significant discomfort, but the device's appearance was a substantial barrier to entry.

  • Facebook marketing had a 4% click rate, 100 likes, and shares.

  • 4B TAM was determined.

Next Steps: Create A ski device that fits under ski pants like traditional knee braces.

Pilot Group 3: Military - Lift and run

DARPA testing was ongoing, but 100 units were ordered for field testing. A primary use case was moving heavyweights over rugged terrain.

Next Steps: Create a device that could be mass-produced to a military spec.

Conclusion:

ROAM continued to grow and develop products after I left, but the three main user groups I discovered and piloted remain their primary markets to this day. The military was the easy short-term market because they already secured active funding from DARPA, but they are still actively selling and testing a skiing device for commercial use.
