We all have that one friend whose office seems to be the nearest airport gate. We go to them for travel advice and hit save on their latest post for that hole-in-the-wall restaurant that had the best local food. That type of advice — especially between women — is indispensable for solo travelers, and now a new travel app based in Austin is helping organize it on a new platform without the social media noise.

Solo travel has gained a lot of momentum in the past few years, and it’s no longer just something one does during a gap year before or after college. It’s become the preferred way to travel for many, and women are at the forefront.

According to Condor Ferries, 72 percent of American women like to take solo trips, and the term “female solo travel” has increased 62 percent over the past three years across all search engines. What if there was a place where women solo travelers could get recommendations and travel itineraries created by other solo women travelers?

This concept is the backbone of Airheart, which aims to revolutionize the travel industry by offering a safe space for solo female travelers to find itineraries and travel guides that were crafted with them in mind.

"Traveling solo as a woman is an empowering act of independence," said Airheart founder Lindsey Renken in a press release. "At Airheart, we celebrate and support this journey, helping women discover new places, connections, and strengths."

The platform includes integrated planning tools, interactive maps, itineraries, and video tips all conveniently located in one place and customizable to the traveler’s preference. Once a user creates an account and accesses the site, the navigation is pretty straightforward.

There’s an explore option at the top of the home screen showcasing all the travel guides available for purchase within the platform, with destinations all over the world. At the moment, most are within the US, Mexico, Western Europe, and Asia. Once the user chooses a guide, a sidebar populates with a list of recommendations or a day-by-day itinerary. The right side of the screen is a map with all the pinned recommendations for easy navigating.

For those wanting to travel more within Texas this summer, Airheart offers a few destinations with a wide range of activities:

  • Big Bend/West Texas: For nature lovers, explore the beautiful mountain desert region of West Texas with a comprehensive guide that includes tips on how to get there and how to choose the best accommodation for your trip — something that becomes more complex in such a remote place.
  • Glen Rose: Escape to this charming small town just an hour-and-a-half Southwest of Dallas-Fort Worth, that is perfect for a weekend getaway full of outdoor adventures. These recommendations come from a local.
  • Fredericksburg: Indulge in the best wineries and restaurants that Central Texas has to offer with an itinerary crafted by a Texas native. This one is ideal for a quick day trip or a fun girls’ weekend.

Airheart, named after the pioneering aviator Amelia Earhart, is also focused on empowering female travel creators by allowing them to act as a type of modern travel agent. They can monetize both new and existing travel content by creating these guides and itineraries, while reaching a new audience on the platform.

“As an avid traveler, I’m always looking for something like this created by expert travelers. I can’t wait to be a seller and consumer,” said Tanna Wasilchak who contributed guides for Waco, Glen Rose, and Georgetown. “Solo traveling as a female can be intimidating at first, but it’s one of the most rewarding experiences I’ve ever had. Airheart is going to be such a game changer for this community.”

Perhaps the only downside for now is that Airheart is limited in what it can offer to its users with only 22 guides published on the site. However, the features and community-based aspect give the platform the potential to stand out in an otherwise saturated market. Guides ($29 each before taxes and fees) are available for users to browse and purchase at airheart.com.

Houston-based travel tech startup raises nearly $1M to continue expansion

token-based travel

A travel booking technology company that's looking to alleviate some of the stresses of finding and making hotel reservations has raised additional seed funding.

Houston-based Pinktada has raised additional funding to the tune of $975,000. Ireland-based Selenean Capital contributed to the seed funding round, joining the company's previous investor True Global Ventures 4 Plus, which has invested $2 million to date. According to Crunchbase data, the latest investment brings the company's total to $3.9 million.

“Selenean Capital’s approach to partnership is identifying real world future needs and then working relentlessly to achieve those goals," says Davin Browne, Selenean’s CEO, in a news release. "Pinktada encapsulates this perfectly with a transformational approach to the hotel booking model built around a brilliant team. We look forward to the partnership and journey with them."

Founded in 2020, Pinktada launched its booking platform earlier this year. The technology — backed by NFT encryption — allows users to sell or trade existing lodging reservations. As many hotels and third-party booking sites offer cheaper non-refundable booking options, Pinktada gives travelers a secure alternative if their plans change. The company's hotel partners can benefit from the transactions, too, per the company's statement.

“We are thrilled with the market validation we are receiving,” says Mark J. Gordon, chief hospitality officer, in the release. “We launched in May with properties in Hawaii and the Dominican Republic, have since added exquisite hotels in Mexico, New York, Miami and San Francisco, and have another 18 in the process of being on-boarded. More important though is the caliber of our partners, which are leading hotel industry names.”

According to the company, membership grew 20 percent in August and 40 percent in September as the platform added new hotel partners.

“We could not be more excited about our prospects," says Lyon Hardgrave, Pinktada’s CEO, in the release. “This investment reflects the significant progress we have made this year. It will allow us to accelerate the onboarding of new hotels, dial up marketing efforts, and continue to evolve our technology to embrace other large opportunities.”

B2B travel company grows its Houston presence

travel tech

Real-time inventory software enables travelers to book a last minute flight and have their boarding passes in hand at security a few minutes later. But that technology isn't utilized in other aspects of a vacation — tour companies, for example. That's where San Francisco-based Xola comes in.

Scott Zimmerman and his co-founder Anush Ramani realized real-time technology was a glaring hole in a multi-billion-dollar business. It's why they founded Xola, a booking and marketing software system designed for tour and activity companies.

"So many smaller tour companies operate with pen and paper," Zimmerman explained. "And for many cities and countries, tourism is the number-two or number-three industry — it's a huge driver of economic growth. It's a $120 billion global market."

They created Xola as a B2B solution that created a platform for operators to promote their offerings, and allow customers to purchase tours and activities. Meanwhile, Xola's custom-design software platform managed the tour inventory and payments, providing real-time inventory management.

Since its inception in 2011, Xola has emerged as a leading B2B solution for travel industry operators. The company started in San Francisco, but opened an office in Houston in 2016 in the Heights Clock Tower. Xola's Houston operation began with six people; today, it employs 17. Zimmerman says he sees potential to grow the team with additional marketing, sales, and support staff.

"We serve customers around the world, and Houston has everything we need to continue our growth."

Zimmerman acknowledged the cost of doing business in the Bay Area is expensive, but when he went looking for cities in which to expand, price wasn't his only concern.

"We wanted a large metropolitan area, with a diverse ecosystem, good universities, a great talent pool, a high quality of life and an affordable cost of living. Houston has all these things. And the more I get to know the city, I realize just how much it has going on."

Zimmerman said that the city has "totally exceeded" his expectations in terms of Xola's growth. He said every one of the Houston employees is wonderful to work with, and loves that they come from diverse cultural and educational backgrounds.

"I can't quite describe what the office is like, but there's a great energy and enthusiasm. [The team] easy to work with. It's been fun in that regard."

Zimmerman said that Houston's talent pool is so extensive, he can't imagine "ever exhausting" the city's resources. He also sees Houston as an asset for Xola's continued growth. The company currently has offices in San Francisco, Houston, Bangalore, and Belgrade and anticipates more expansion in the coming years. Xola's ticketing and software system has received multiple five-star reviews from its customers, who praise not only its ease of operation, but also the company's stellar customer service. In fact, Xola just won a 2018 Ease of Use Award from Capterra.

"In addition to Xola's core booking system, we're building next-generation automated marketing features that help our customers maintain a competitive edge. And our Houston team will continue to grow as we do, so we can continue to serve markets around the world."

Houston-based, NASA-founded cleantech startup closes $12M seed round

Fresh Funds

Houston-based Helix Earth Technologies has closed a $12 million Seed 2 funding round to scale manufacturing of its energy-efficient commercial HVAC add-on technology.

Veriten, a Houston-based energy investment firm, led the round. Rua Ventures, Carnrite Ventures, Skywriter LLC and Textbook Ventures also participated.

Helix Earth—which was founded based on NASA technology, spun out of Rice University and has been incubated at Greentown Labs—is developing high-efficiency retrofit dehumidification systems that aim to reduce the energy consumption of commercial HVAC units. The company reports that its technology can lead to "healthier indoor air, lower energy bills, reduced building maintenance, and more comfortable spaces for building owners and occupants."

"Building owners are dealing with rising energy costs, uncontrolled humidity, and aging infrastructure with no viable, cost-effective path forward. We are in the field today solving these problems for commercial customers, and this capital puts us on an aggressive path to scale,” Rawand Rasheed, Helix Earth co-founder and CEO, said in a news release.

“The strength of this round reinforces our team's conviction that we can transform innovation-starved sectors with transformational solutions that deliver order-of-magnitude improvements to owners and operators, for both their bottom line and the environment,” Rasheed added.

Maynard Holt, Veriten’s founder and CEO, said that the investment firm is tripling its investment in Helix Earth.

"The team has built breakthrough technology with real applicability across multiple industries,” Holt said in the release. “Their first product will have an immediate and measurable impact on our energy system, and they are already pursuing adjacent innovations to help heavy industries operate more efficiently and with less waste. This is a well-rounded team with a proven track record of strong execution and disciplined capital management.”

Helix Earth also closed a $5.6 million seed funding round in 2024, led by Veriten.

Last year, the company secured a $1.2 million Small Business Innovation Research (SBIR) Phase II grant and won in the Smart Cities, Transportation & Sustainability contest at the 2025 SXSW Pitch Showcase. Rasheed was also named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.
