The Rice Innovation Fellows program assists doctoral students and postdoctoral researchers with training and support to turn their ideas into ventures. Alumni have raised over $20 million in funding and grants, according to Lilie. Last year's group included 10 doctoral and postdoctoral students working in fields such as computer science, mechanical engineering and materials science.

“The Innovation Fellows program helps scientist-led startups accelerate growth by leveraging campus resources — from One Small Step grants to the Summer Venture Studio accelerator — before launching into hubs like Greentown Labs, Helix Park and Rice’s new Nexus at The Ion,” Yael Hochberg, head of the Rice Entrepreneurship Initiative and the Ralph S. O’Connor Professor in Entrepreneurship, said in the release. “These ventures are shaping Houston’s next generation of pillar companies, keeping our city, state and country at the forefront of innovation in mission critical industries.”

Houston startup Collide secures $5M to grow energy-focused AI platform

Fresh Funds

Houston-based Collide, a provider of generative artificial intelligence for the energy sector, has raised $5 million in seed funding led by Houston’s Mercury Fund.

Other investors in the seed round include Bryan Sheffield, founder of Austin-based Parsley Energy, which was acquired by Dallas-based Pioneer Natural Resources in 2021; Billy Quinn, founder and managing partner of Dallas-based private equity firm Pearl Energy Investments; and David Albin, co-founder and former managing partner of Dallas-based private equity firm NGP Capital Partners.

“(Collide) co-founders Collin McLelland and Chuck Yates bring a unique understanding of the oil and gas industry,” Blair Garrou, managing partner at Mercury, said in a news release. “Their backgrounds, combined with Collide’s proprietary knowledge base, create a significant and strategic moat for the platform.”

Collide, founded in 2022, says the funding will enable the company to accelerate the development of its GenAI platform. GenAI creates digital content such as images, videos, text, and music.

Originally launched by Houston media organization Digital Wildcatters as “a professional network and digital community for technical discussions and knowledge sharing,” the company says it will now shift its focus to rolling out its enterprise-level, AI-enabled solution.

Collide explains that its platform gathers and synthesizes data from trusted sources to deliver industry insights for oil and gas professionals. Unlike platforms such as OpenAI, Perplexity, and Microsoft Copilot, Collide’s platform “uniquely accesses a comprehensive, industry-specific knowledge base, including technical papers, internal processes, and a curated Q&A database tailored to energy professionals,” the company said.

Collide says its approximately 6,000 platform users span 122 countries.

Houston femtech co. debuts first holistic wellness suite following rebrand

work perks

Houston-based femtech company Work&, previously Work&Mother, debuted new lactation suites and its first employee wellness space at MetroNational’s Memorial City Plazas this month.

The 1,457-square-foot Work& space features three lactation rooms and five wellness suites, the latter of which are intended to offer employees a private space and time for telehealth appointments, meditation, prayer, and other needs. The hybrid space, designed by Houston-based Inventure, represents Work&'s shift to offer an array of holistic health and wellness solutions to landlords for tenants.

Work& rebranded from Work&Mother earlier this year. The company was previously focused on outfitting commercial buildings with lactation accommodations for working parents, equipped with a hospital-grade pump, milk storage bags, sanitizing wipes, and other supplies. While Work& will still offer these services through its Work&Mother branch, the addition of its Work&Wellbeing arm allows the company to also "address the broader wellness needs of all employees," according to an announcement made on LinkedIn.

"We are thrilled to bring Work&Mother and Work&Wellbeing to The Plazas," Jules Lairson, co-founder and COO of Work&, said in a news release. “This partnership brings every stakeholder together – employees, employers and landlords all benefit from this kind of forward-thinking tenant experience. We are excited to launch our Work&Wellbeing concept with MetroNational to ensure that all employees have their wellness needs met with private, clean, quiet spaces for use during the workday.”

The new space is available to all tenants across Memorial City Plazas, comprised of three office towers totaling 1 million square feet of Class A office space. In addition to the lactation and wellness suites, the space also features custom banquettes, private lounge seating and phone booths.

“As a family-owned and operated company, MetroNational is deeply committed to fostering a workplace that supports both productivity and the well-being of all our tenants,” Anne Marie Ratliff, vice president of asset management for MetroNational, added in the release. “Partnering with Work& reinforces this commitment, enhancing our workplace experience and setting a new standard for tenant amenities.”

Work& has five Houston locations and several others in major metros, including New York, Austin, D.C., Boston, Chicago, San Francisco, and Miami. According to its website, the company will also introduce a Work&Wellbeing suite in New York.
