Houston is a humid subtropical climate — the majority of the year brings hot and sticky weather. Local entrepreneur Kristina Haag found herself struggling to find traditional clothing that is comfortable in the Texas heat, so she created it herself.

"With Cotidié, it is all about the functionality of the clothing," says Haag, founder of the clothing line Cotidié. "It is more traditional items, but the use of technical fabrics is our differentiating factor."

The online retailer, which launched in June 2019, offers pieces specifically tailored for women who are up against Houston's hot and muggy climate.

The line offers dresses, jackets, pants, skirts, and tops, ranging between $60 and $200 in price. The fabrics, sourced from Italy and Taiwan, provide breathable comfort, along with an elastic, structured fit for a more tailored look. All items are moisture wicking and machine washable. The line uses three different fabrics: LunAir, 88 percent polyester and 12 percent spandex; SolaSmooth, 73 percent nylon and 27 percent elastane; and StellaForm, 59 percent nylon and 41 percent elastane.

"Everything we use on the line is athletic technical fabric that you would typically find in workout attire, but I've repurposed these fabrics to use in a contemporary womenswear line," Haag tells InnovationMap. "I wanted to create a more foundational capsule clothing collection that women can draw their own inspiration from."

Haag, originally from Houston, studied history and business at Rice University before moving to London to attend the British School of Fashion. Following a few years of work at a London-based fashion PR firm, she returned to Texas. Haag was working a corporate job that required extensive job-site visits.

"I thought, how is there not more stylish women's clothing on the market that is comfortable and functional," says Haag.

The name Cotidié, which means "daily" or "every day," encompasses Haag's desire to create clothing that can be worn at work, for travel, on weekends, and more. Haag was determined to find comfortable professional clothing that held up in Houston's heat and humidity and created Cotidié to bridge the gap between technical performance wear and business attire, introducing a new kind of clothing for stylish women on the go.

Haag worked for over a year testing different fabrics and designing each piece to blend feminine style with technical performance. Haag works with Sew Pro Production, an apparel manufacturer based in Houston to develop the pieces.

For Cotidié's fall and winter line, which launched in October 2019, Haag adapted the pieces for cooler weather as the temperature shifts.

Haag plans to expand the marketing of Cotidié to a national scale in the next year. The company currently has two employees and has plans to begin fundraising efforts in 2020. The company currently ships internationally.

Ty Audronis and his company, Tempest Droneworx, made a splash at SXSW Interactive 2025, winning the Best Speed Pitch award at the annual festival. The company is known for it flagship product, Harbinger, a software solution that agnostically gathers data at virtually any scale and presents that data in easy-to-understand visualizations using a video game engine. Audronis says his company won based on its merits and the impact it’s making and will make on the world, beginning with agriculture. Learn more.

Houston-based Persona AI and CEO Nicolaus Radford continue to make steps toward deploying a rugged humanoid robot, and with that comes the expansion of its operations at Houston's Ion. Radford and company will establish a state-of-the-art development center in the prominent corner suite on the first floor of the building, with the expansion slated to begin in June. “We chose the Ion because it’s more than just a building — it’s a thriving innovation ecosystem,” Radford says.

Houston university to launch artificial intelligence major, one of first in nation

BS in AI

Rice University announced this month that it plans to introduce a Bachelor of Science in AI in the fall 2025 semester.

The new degree program will be part of the university's department of computer science in the George R. Brown School of Engineering and Computing and is one of only a few like it in the country. It aims to focus on "responsible and interdisciplinary approaches to AI," according to a news release from the university.

“We are in a moment of rapid transformation driven by AI, and Rice is committed to preparing students not just to participate in that future but to shape it responsibly,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, said in the release. “This new major builds on our strengths in computing and education and is a vital part of our broader vision to lead in ethical AI and deliver real-world solutions across health, sustainability and resilient communities.”

John Greiner, an assistant teaching professor of computer science in Rice's online Master of Computer Science program, will serve as the new program's director. Vicente Ordóñez-Román, an associate professor of computer science, was also instrumental in developing and approving the new major.

Until now, Rice students could study AI through elective courses and an advanced degree. The new bachelor's degree program opens up deeper learning opportunities to undergrads by blending traditional engineering and math requirements with other courses on ethics and philosophy as they relate to AI.

“With the major, we’re really setting out a curriculum that makes sense as a whole,” Greiner said in the release. “We are not simply taking a collection of courses that have been created already and putting a new wrapper around them. We’re actually creating a brand new curriculum. Most of the required courses are brand new courses designed for this major.”

Students in the program will also benefit from resources through Rice’s growing AI ecosystem, like the Ken Kennedy Institute, which focuses on AI solutions and ethical AI. The university also opened its new AI-focused "innovation factory," Rice Nexus, earlier this year.

“We have been building expertise in artificial intelligence,” Ordóñez-Román added in the release. “There are people working here on natural language processing, information retrieval systems for machine learning, more theoretical machine learning, quantum machine learning. We have a lot of expertise in these areas, and I think we’re trying to leverage that strength we’re building.”
