When Brittany Baretto was 18 years old and sitting in an undergraduate genetics seminar, she raised her hand. She asked, to her professor's point, if particular DNA trait differences between two people can result in attraction, could she, based on that logic, make a DNA-based dating tool. With that question, she set in motion a series of events.

These events included teaming up with Bin Huang to start a dating app, called Pheramor, that factored in user DNA; raising millions for the company; hiring a team from across the country; and signing up users in all 50 states. Though, Pheramor's hockey stick growth came to a sudden stop this year when Apple pulled the app from its store, and there was nothing the founders or their investors could do about it.

"They are gatekeepers in innovation," Barreto learned the hard way.

InnovationMap recently spoke with Barreto to discuss the rise and fall of Pheramor and lessons learned.

Launching the first nationwide DNA-based dating app

Barreto mulled over the idea for the company through college and through her genetics PhD program before starting the company in 2017.

"I actually formed the C-Corp the same month that Accenture put out its report on Houston needing more attention on its startups and innovation," she says. "I didn't know about that report. I was really lucky with Pheramor to ride the wave of Houston growing its startup community."

She went on to fundraise $1.3 million, and, at its height, Pheramor had 10 employees working out of WeWork in the Galleria. Pheramor was the first nationwide DNA-based dating app, and for that she will always be proud, Barreto says.

"We were growing something not necessarily unicorn status growth, but we were doing something really different," she says. "And we knew we were growing something valuable. At our peak, we had 250 downloads a day."

Venture capitalists were taking note, Barreto says, and she was on her way to closing another round — this time for $2.2 million.

Getting the call

In March, Barreto and Huang attended Enventure's bioventure pitch event, where, just three years prior, the duo had pitched and won thousands of dollars. It was a real turning point, Barreto remembers.

Earlier that day, they had seen some issues with Apple's app store and filed a service request. As she left the event, Barreto's phone rang, and it was an Apple representative explaining that the Pheramor app had been pulled from the store. New rules for the App Store had been set in place — rules that forbid dating apps from procuring DNA samples from users.

Once the DNA element was removed from the app, Pheramor would be allowed back on, Barreto was told.

"That was our differentiator," she says. "That was the thing that made us Pheramor."

For the next three weeks, Barreto called every app reviewer at Apple and challenged each "no" she got.

"I had that internal founder drive. I was like, 'No, I just need to talk to someone. I'm going to hustle around this.'"

Her request went to the very top, before receiving one final, inarguable "No."

Barreto knows why Apple instituted the new policy — biohackers are the newest cyber threat in the world. But she was being dragged through the ringer while watching her startup slowly slip away, and the anonymous Apple employees on the other end of the phone had no sympathy for her inner turmoil.

"It felt like they just kept reading a script," she says, adding that it was the most painful experience for her. "The insensitivity of the app review people was salt in the wound."

Throwing a Hail Mary

The Pheramor app was still live on Google, Barreto says, but with only 10 percent of the market, and data showing that Android users are historically non-buyers, she knew she had to pivot.

Huang and his team turned around an idea for a couples' compatibility test based on DNA, and WeHaveChemistry.com was born. Barreto tapped an acclaimed relationship expert, Laura Berman, as a strategic adviser. She made a deal with her board — if they could sell 100 of these kits in 60 days, they'll make new goals and keep the testing live.

Barreto says they sold some, but ultimately in June, after not meeting that goal, she suggested to the board the company should sell its assets, if possible, to help pay back her investors.

While the investors of Pheramor's $2.2 million round had pulled out at this point, Pheramor still had $100,000 in the bank. Barreto says she budgeted about $30,000 to legally close the company. At this point, she had laid off her staff, and it was down to the co-founders. Both got new jobs — Huang is now the head data scientist at Houston-based BrainCheck, and Barreto joined Capital Factory as its Houston-based venture associate.

Since Barreto was actively trying to sell the assets, she kept quiet about Pheramor's downfall. While she had some interest, ultimately, people told her the technology was too complicated or that they wouldn't buy unless Barreto came with the company.

"I realized that over the past two years, I had already been ad hoc coaching and mentoring founders and loving it," Barreto says. "Now, I was doing it and getting paid for it, on a bigger scale, and with more resources. I knew it was the journey I wanted to continue down."

Lessons thoroughly learned

Barreto's past six months have been a rollercoaster, to say the least. Losing Pheramor felt like an identity crisis for her.

"I was very personally involved with the brand," she says. "So when Pheramor was gone, it was like, 'Who am I?'"

She had to keep most of her inner turmoil hidden from the startup community, especially since she was trying to sell Pheramor's assets. She battled an eating disorder and lost chunks of her hair, all the while she felt like she had to keep a smile on her face.

"As a female founder, I felt so much pressure to win. It felt like stakes were higher for me," Barreto says. "I felt really nervous to let my insides show."

She did find a few entrepreneurs that helped to guide her with their own perspective and careers, and Barreto says she leaned on her lawyer, Nicole Moss, a Houston-area startup lawyer, to help talk her through things. One surprising confidant was one of her investors, Jack Gill.

Barreto remembers meeting with Gill and thinking she was about to have to apologize for losing a ton of his money, but instead, he hugged her and congratulated on her first failure — that Pheramor's demise made her a real entrepreneur.

"His pride was a big turning point for me. I realized, 'Wow, this is really a jumping off point,'" she says.

This, of course, was directly contrasted by other investor's extreme disappointment. In the end, Barreto paid back investors by about 5 percent. She also realized the difference of working with investors who are new to the process.

"I learned a lesson of taking money from people who are not experienced investors will cause you headaches along the way," she says.

What's next? Funding femtech.

These investor lessons learned are especially important to Barreto, who wants her next startup to be a venture fund focused on empowering the marginalized entrepreneurs — female founders, the LGBT community, minorities, etc.

"I want to be someone of influence for social good," she says. "This crazy idea I had for a dating app was just a way to propel me to becoming that person. I felt like it did that."

Flipping to the other side of the investor table is appealing to Barreto, because she feels like she's able to make more of an impact.

"What I learned from Pheramor is I put all my eggs in one basket, and something happened and all my eggs broke," she says. "As a VC, you put your eggs in lots of baskets. If I want to make big change, I can probably do that more effectively if I'm empowering 20 different companies instead of doing only one thing."

Her idea is to raise a femtech fund that invests in startups and entrepreneurs with products or services within women's health.

"For me, as long as you're working on a technology that improves women's health and wellness, I want to invest in you," she says.

It's taken her a long time to get to this point, but ultimately, Barreto has realized that she did everything she could do, and she's better for this journey — no matter how rough it is. More importantly to Barreto, she sees this as an opportunity to share her story of failure — though, she wishes there were a better word for it — so that other entrepreneurs don't feel so alone in the process. She hopes that Pheramor's legacy can fill that need.

"We need to get comfortable with failure and support each other in the journey," she says.

UH student earns prestigious award for cancer vaccine research

up-and-comer

Cole Woody, a biology major in the College of Natural Sciences and Mathematics at the University of Houston, has been awarded a Barry Goldwater Scholarship, becoming the first sophomore in UH history to earn the prestigious prize for research in natural sciences, mathematics and engineering.

Woody was recognized for his research on developing potential cancer vaccines through chimeric RNAs. The work specifically investigates how a vaccine can more aggressively target cancers.

Woody developed the MHCole Pipeline, a bioinformatic tool that predicts peptide-HLA binding affinities with nearly 100 percent improvement in data processing efficiency. The MHCole Pipeline aims to find cancer-specific targets and develop personalized vaccines. Woody is also a junior research associate at the UH Sequencing Core and works in Dr. Steven Hsesheng Lin’s lab at MD Anderson Cancer Center.

“Cole’s work ethic and dedication are unmatched,” Preethi Gunaratne, director of the UH Sequencing Core and professor of Biology & Biochemistry at NSM, said in a news release. “He consistently worked 60 to 70 hours a week, committing himself to learning new techniques and coding the MHCole pipeline.”

Woody plans to earn his MD-PhD and has been accepted into the Harvard/MIT MD-PhD Early Access to Research Training (HEART) program. According to UH, recipients of the Goldwater Scholarship often go on to win various nationally prestigious awards.

"Cole’s ability to independently design and implement such a transformative tool at such an early stage in his career demonstrates his exceptional technical acumen and creative problem-solving skills, which should go a long way towards a promising career in immuno-oncology,” Gunaratne added in the release.

Houston founder on shaping the future of medicine through biotechnology and resilience

Guest Column

Living with chronic disease has shaped my life in profound ways. My journey began in 5th grade when I was diagnosed with Scheuermann’s disease, a degenerative disc condition that kept me sidelined for an entire year. Later, I was diagnosed with hereditary neuropathy with liability to pressure palsies (HNPP), a condition that significantly impacts nerve recovery. These experiences didn’t just challenge me physically, they reshaped my perspective on healthcare — and ultimately set me on my path to entrepreneurship. What started as personal health struggles evolved into a mission to transform patient care through innovative biotechnology.

A defining part of living with these conditions was the diagnostic process. I underwent nerve tests that involved electrical shocks to my hands and arms — without anesthesia — to measure nerve activity. The pain was intense, and each test left me thinking: There has to be a better way. Even in those difficult moments, I found myself thinking about how to improve the tools and processes used in healthcare.

HNPP, in particular, has been a frustrating condition. For most people, sleeping on an arm might cause temporary numbness that disappears in an hour. For me, that same numbness can last six months. Even more debilitating is the loss of strength and fine motor skills. Living with this reality forced me to take an active role in understanding my health and seeking solutions, a mindset that would later shape my approach to leadership.

Growing up in Houston, I was surrounded by innovation. My grandfather, a pioneering urologist, was among the first to introduce kidney dialysis in the city in the 1950s. His dedication to advancing patient care initially inspired me to pursue medicine. Though my path eventually led me to healthcare administration and eventually biotech, his influence instilled in me a lifelong commitment to medicine and making a difference.

Houston’s thriving medical and entrepreneurial ecosystems played a critical role in my journey. The city’s culture of innovation and collaboration provided opportunities to explore solutions to unmet medical needs. When I transitioned from healthcare administration to founding biotech companies, I drew on the same resilience I had developed while managing my own health challenges.

My experience with chronic disease also shaped my leadership philosophy. Rather than accepting diagnoses passively, I took a proactive approach questioning assumptions, collaborating with experts, and seeking new solutions. These same principles now guide decision-making at FibroBiologics, where we are committed to developing groundbreaking therapies that go beyond symptom management to address the root causes of disease.

The resilience I built through my health struggles has been invaluable in navigating business challenges. While my early career in healthcare administration provided industry insights, launching and leading companies required the same determination I had relied on in my personal health journey.

I believe the future of healthcare lies in curative treatments, not just symptom management. Fibroblast cells hold the promise of engaging the body’s own healing processes — the most powerful cure for chronic diseases. Cell therapy represents both a scientific breakthrough and a significant business opportunity, one that has the potential to improve patient outcomes while reducing long-term healthcare costs.

Innovation in medicine isn’t just about technology; it’s about reimagining what’s possible. The future of healthcare is being written today. At FibroBiologics, our mission is driven by more than just financial success. We are focused on making a meaningful impact on patients’ lives, and this purpose-driven approach helps attract talent, engage stakeholders, and differentiate in the marketplace. Aligning business goals with patient needs isn’t just the right thing to do, it’s a powerful model for sustainable growth and lasting innovation in biotech.

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”
