As a busy lawyer who traveled heavily for work, Sylvia Kampshoff found her workouts were often overlooked as she went from city to city, a casualty of long hours and a busy schedule. And, even though she did have a membership to a national gym with privileges at any of its locations, she hated the feeling of always being sold something and disliked that both the trainers and managers she worked with took very little interest in her personal needs and fitness goals.

She wanted something that allowed her to exercise with someone on her own schedule, and with people who valued customer service. That's how the idea for Kanthaka was born.

The app uses location technology similar to that of ride sharing apps to allow users to book training sessions with certified personal trainers, all of whom are heavily vetted and background checked by Kampshoff and her team.

"Many trainers at gyms or who work privately aren't certified," she says. "And that was important to me, that we have professionals who understand training and the body. And making sure our clients felt safe was a huge priority for me. We interview every trainer personally to ensure they not only meet our standards but also share our goals."

App users can select a trainer who will lead them in a Pilates, yoga, boxing, general training, or a pre- or post-natal workout. They select their location, as well as the date and they want to schedule a session. They can book a single session for $42 for a 45-minute session or $50 for an hour session or purchase a package of six or 12 workouts. There's no long-term commitment — although Kampshoff says that some clients are asking for a monthly subscription option — and the process is designed to be easy and user friendly. Trainers will arrive at a client's home, office, or their preferred gym, providing the gym allows outside trainers to work there.

The app launched in Houston in 2017 and then in Austin this fall. Over the last year, Kampshoff — who left the legal profession to concentrate on Kanthaka's success — says she's learned a lot about the market and her own preconceptions.

"I figured it was going to be business travelers who used it, people who were like me when I was doing all that travel," she says. "But it turns out that we're seeing people use it who want to schedule a session just like any other appointment. Many of our clients are women, who value the rigorous vetting process we have for our trainers."

In addition to vetting the trainers and confirming their certifications with the National Academy for Sports Medicine or the American Council on Exercise, each trainer is reviewed by app users, to help others determine whether that person would be a good fit for their needs. Kanthaka allows users to "favorite" trainers, and book them again, and user testimonials tout Kanthaka's easy of use and great training team.

In addition to individual users who find the app via social media or internet searches, Kampshoff has developed partnerships with hotels and apartments around Houston. Kanthaka provides personal training services to guests at the Post Oak Hotel, and Hanover apartment properties list the app as a feature for its residents.

As she continues to grow the business and expand in other cities, Kampshoff is excited to see others buying into her concept of fitness.

"There is a culture behind Kanthaka. It's about health and fitness, but also achieving the lifestyle you want that allows you to feel better and live in a more positive way."

Houston DNA-based dating app expands nationwide, launches next funding round

From swiping to swabbing

Houston singles can find their perfect match — even if it's someone across the country. Houston-based Pheramor — a DNA-based dating app — is available for download in every state.

Brittany Barreto, Pheramor's co-founder and CEO, has a PhD in genetics from Baylor College of Medicine. She first had the idea in a genetics seminar when she was 18 and in college, but that was almost 10 years ago, and the market wasn't ready. Now, she says singles have swipe fatigue from the existing and ineffective dating apps, and it's also relatively normal now to send your spit in the mail thanks to 23AndMe.

Pheramor users download the app and request a test kit. After a few cheek swabs, they send it back to Barreto and her team and they identify 11 immune system genes and upload the data to the user's profile. The app then compares the genes to other users to give a compatibility score.

"The science behind attraction based on your DNA is that people are attracted to one another when their immune systems are different — opposites attract is biologically true," Barreto says. "When we were cavewomen and cavemen, we didn't know who was our uncle and who was our cousin, so we used our nose to figure out who is genetically diverse compared to us. If you're genetically diverse, then you're probably not my relative, and therefore we'd have healthier children."

Pheramor also calculates a social score based on a questionnaire or a data mine of a user's social media. The overall compatibility score uses both the DNA and social compatibility scores.

The app launched in Houston in March to a great reception of local singles, but, a few months later, Barreto realized nothing was holding them back from expanding nationwide.

"We surveyed our user base and asked them if they had highly compatible numbers with someone in, say, Chicago, would they want to know," Barreto says. "And something like 89 percent said yes."

Pheramor users are usually between 28 and 38, have good paying jobs, and are seeing commitment, Barreto says. Most of them travel around a lot already.

"We opened it up on September 7, and in 30 days we saw over 50 percent growth in our user base."

The company has zeroed in on a few key metros where advertising dollars go a long way for generating user downloads; Boston, New York, San Francisco, Los Angeles, and Miami have all been great markets for Pheramor.

With the user base growing, Barreto is focused on growing her team. Pheramor's current round of funding launched November 1, and with the capital raised, she hopes to be able to make the team's CFO and chief marketing officer both full time.

Pheramor is also working on using its custom algorithm as a resource to other existing dating services worldwide as well as for couples who want to see their compatibility score with their current partners.

"A long-term goal that's coming to fruition a lot faster than I thought is Pheramor being a leader in genetic testing for romance," Barreto says.

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”

Intuitive Machines forms partnership with Italian companies for lunar exploration services

to the moon

Houston-based space technology, infrastructure and services company Intuitive Machines has forged a partnership with two Italian companies to offer infrastructure, communication and navigation services for exploration of the moon.

Intuitive Machines’ agreement with the two companies, Leonardo and Telespazio, paves the way for collaboration on satellite services for NASA, a customer of Intuitive Machines, and the European Space Agency, a customer of Leonardo and Telespazio. Leonardo, an aerospace, defense and security company, is the majority owner of Telespazio, a provider of satellite technology and services.

“Resilient, secure, and scalable space infrastructure and space data networks are vital to customers who want to push farther on the lunar surface and beyond to Mars,” Steve Altemus, co-founder and CEO of Intuitive Machine, said in a news release.

Massimo Claudio Comparini, managing director of Leonardo’s space division, added that the partnership with Intuitive Machines is a big step toward enabling human and robotic missions from the U.S., Europe and other places “to access a robust communications network and high-precision navigation services while operating in the lunar environment.”

Intuitive Machines recently expanded its Houston Spaceport facilities to ramp up in-house production of satellites. The company’s first satellite will launch with its upcoming IM‑3 lunar mission.

Intuitive Machines says it ultimately wants to establish a “center of space excellence” at Houston Spaceport to support missions to the moon, Mars and the region between Earth and the moon.
