show me the money

A Houston venture capital firm has announce big news of its latest fund.

Mercury, founded in 2005 to invest in startups not based in major tech hubs on either coast, closed its latest fund, Mercury Fund V, at an oversubscribed amount of $160 million. Originally expected to raise $150 million, Fund V is the largest fund Mercury has raised to date.

“We are pleased by the substantial support we received for Fund V from both new and existing investors and thank them for placing their confidence in Mercury,” Blair Garrou, co-founder and managing director of Mercury Fund, says in a news release. “Their support is testament to the strength of our team, proven investment strategy, and the compelling opportunities for innovation that exist in cities across America.”

The fund's limited partners include new and existing investors, including endowments at universities, foundations, and family offices. Mercury reports that several of these LPs are based in the central region of the United States where Mercury invests. California law firm Gunderson Dettmer was the fund formation counsel for Mercury.

Fresh closed, Fund V has already made investments in several companies, including:

  • Houston-based RepeatMD, a patient engagement and fintech platform for medical professionals with non-insurance reimbursed services and products
  • Houston and Cheyenne Wyoming-based financial infrastructure tech platform Brassica, which raised its $8 million seed round in April
  • Polco, a Madison, Wisconsin-based polling platform for local governments, school districts, law enforcement, and state agencies
  • Chicago-based MSPbots, a AI-powered process automation platform for small and mid-sized managed service providers

Mercury's investment model is described as "operationally-focused," and the firm works to provide its portfolio companies with the resources needed to grow rapidly and sustainably. Since 2013, the fund has contributed to creating more than $9 billion of enterprise value across its portfolio of over 50 companies.

“Over the past few years there has been a tremendous migration of talent, wealth and know-how to non-coastal venture markets and this surge of economic activity has further accelerated the creation of extraordinary new companies and technology," says Garrou. "As the first venture capital firm to have recognized the attractiveness of these incredible regions a dozen years ago, we are excited to continue sourcing new opportunities to back founders and help these cities continue to grow and thrive.”

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.”
