Houston experts shine spotlight on impact investing following angel network expansion

calling for impact

Houston innovators called for existing and potential investors to focus on impact investing — for the improvement of both society and your bottom line.

SWAN Impact Network, which announced its expansion into Houston earlier last month, is an investment organization that prioritizes funding mission driven startups and educating angels on how to analyze impact investment companies. The organization hosted a launch event and panel at the Ion last week to discuss the process and goals of impact investing and highlighted their own success stories as angel investors. The panelists included Bob Bridge, Kerri Smith, and Emily Reiser, who were moderated by Grace Rodriguez, executive director of Impact Hub Houston.

Emily Reiser, associate director of the Texas Medical Center’s innovation team, said impact investing, though focused on improving people’s lives through innovations, should still rely on typical business models and return profiles.

“It’s not charity investment, it’s investing with an eye towards how that investment is going to also return to the greater society as well as back to your pockets,” Reiser says.

As there was a mix of prospective angel investors and entrepreneurs in attendance at the event, Reiser encouraged the founders to have formal business plans in place before meeting with investors, from setting up customer feedback systems to budgeting estimates.

“In the impact space you’ll get some great enthusiasm from people who want to join your mission to save lives, or change the world, or save the planet but make sure you do all the rest of the work behind that to build out the rest of your business model, figure out how you’re going to sell, get it optioned, and on the market,” Reiser says.

Bob Bridge, the founder and executive director of SWAN, stressed the importance of examining long term consequences of impact-driven startups. Bridge illustrated the importance of doing research into how these startups could unintentionally harm communities before investing in them by discussing the well known shoe manufacturer TOMS, whose business model revolved around matching each pair of purchased shoes by donating a pair to people in developing countries, putting local manufacturers out of business.

“These companies are often just now entering the market place so they can’t measure their actual impact results yet because they’re not delivering services or products yet,” Bridge says. “We look for them to have some sort of data to give us a clue if what they’re doing is going to work … convince us there is efficacy to what you are doing and that your impact solution is competitive.”

Bridge also adds there is no concrete definition of impact investing because every society has different needs to be met through creative solutions, from developing more robust technology to encouraging the hiring of underrepresented minority groups. When making decisions over which companies to invest in, Bridge says he also prioritizes startup teams that are collaborative and transparent.

“We don’t invest in Steve Jobs' kind of personalities … We want people who are always learning from their customers, competitors, and employees,” he explains.

Kerri Smith, executive director of the Rice Alliance Clean Energy Accelerator program, says her team readies their emerging startups to tackle meetings with investors by asking them to quantify the impact of their technology on users.

“We’re seeing a lot of investors as well as boards of directors requiring companies to be more responsive to those kinds of things,” Smith says. “We try to prepare the startups in ways that will make them more ready to answer questions about the impact that they’re having societally as well as financially.”

Houston university granted $1.2M to expand STEM-focused initiative

science support

Rice University is receiving a five-year $1.2 million grant from the National Science Foundation to expand a program that helps faculty members, researchers, and doctoral students commercialize STEM-oriented technology.

Rice is one of the founding partners of the science foundation’s Southwest I-Corps Node. Rice and the two other founding partners are sharing a $15 million grant to help add five universities to the program.

Rice, Texas A&M University, and the University of Texas established the Southwest node in 2014. The five schools forming a new hub within the node are the University of Texas at San Antonio, the University of Texas at El Paso, Oklahoma State University, New Mexico State University, and Louisiana State University.

The foundation’s I-Corp program not only boosts STEM-related technologies developed at universities, but it also provides $50,000 grants for STEM-based faculty members and doctoral students to participate in a six-week training program to help researchers bring technologies from the lab to the marketplace. Over 1,000 startups have been formed after completing the I-Corps program; they have raised more than $750 million in funding.

Kerri Smith, associate managing director of the Rice Alliance, leads the university’s I-Corps program, along with Kaz Karwowski, executive director of the Rice Center for Engineering Leadership, and Jessica Fleenor, a Rice Alliance I-Corps teaching assistant and I-Corps program manager.

“Thanks to the Rice Alliance’s more than two decades of leadership, Rice has built an entrepreneurial culture on campus, served as a founding member of the I-Corps program, and provided entrepreneurial education to hundreds of faculty and students,” says Reginald DesRoches, president of Rice.

Rice has received more than $3.1 million in National Science Foundation grants for the I-Corps program, plus about $1.3 million as part of the I-Corps node. Rice faculty members and researchers have received more than $600,000 in I-Corps grants.

Previous I-Corps participants at Rice include:

  • Volumetric Biotechnologies, a startup founded by Jordan Miller, an assistant professor of bioengineering assistant professor, and based on Miller’s 3D organ-printing technology. Volumetric was acquired last year by 3D Systems for up to $400 million.
  • SPLAY (formerly Arovia), which completed the I-Corps program in 2015. Through two Kickstarter campaigns, the company has successfully raised money for its high-definition, portable, large-scale computer display technology.

As the managing director for the Rice Alliance for Entrepreneurship and Technology's Clean Energy Accelerator, Kerri Smith is focused not only on the program's cohorts but on supporting the Houston cleantech ecosystem as a whole. CEA works with Greentown Houston, which is just next door to the program's home at The Ion, and the Greater Houston Partnership's Houston Energy Transition Initiative.

"Rice Alliance has a strong history of demonstrating collaboration with a number of organizations," Smith says. "I think one of the primary benefits that we have in these collaborative opportunities is to ensure that we are collectively building a capable and diverse pipeline of talent to solve for these problems and provide them with access to experiencing all of the benefits of our ecosystem."

Smith shares more about what she's looking for in the second cohort of CEA on a recent Houston Innovators Podcast episode, as well as what she sees as Houston's role in the energy transition. Click here to read more and stream the episode.

Cleantech accelerator leader looks forward to new cohort and making an impact on Houston's energy transition

HOUSTON INNOVATORS PODCAST EPISODE 134

Kerri Smith knows accelerators. Through her over 18 years at Rice Alliance, she's been responsible for overseeing several and was on the founding leadership team of Houston's first energy tech startup accelerator, SURGE. After years of focusing you accelerating Rice University's student-focused program, Owl Spark, she's transitioned back into the energy tech space.

"I've worked with many types of founders. There's not one unique characteristic that everyone has," Smith says on the Houston Innovators Podcast. "Our goal is to help move them along and help them move the needle. At the end of the day, we want them to have a good experience and to meet their goals and objectives."

The Rice Alliance's Clean Energy Accelerator launched last summer with its inaugural cohort of 12 cleantech startups, which represented energy sectors from solar and wind innovations to hydrogen, geothermal, and more. Smith says the startups represented a wide range of stages and were from all over — only two companies were from Houston originally. The out-of-town companies were able to make critical partnerships in town and set up a presence and a home here.

"We were able to build a family-like culture among our group, and that was something that was wildly appreciative," Smith, who serves as executive director of the program, says.

Applications for Class 2 of CEA are open until May 31. While the program will offer the same access to mentorship and opportunities, the program will change slightly. CEA will focus on seed and series A-stage companies and will be a hybrid program. Throughout the 10 weeks, which begins in the fall instead of the summer this year, founders will visit Houston three times at the beginning, middle, and the end of the accelerator. Each startup will receive a grant to cover the expenses of the equity-free program.

CEA is just one part of a greater ecosystem of innovation under the umbrella of Rice University, which includes the Rice Alliance for Technology and Entrepreneurship, the Liu Idea Lab for Innovation and Entrepreneurship, The Ion Houston, Owl Spark, and more. All these entities also play into the greater Houston area's innovation ecosystem.

"Rice Alliance has a strong history of demonstrating collaboration with a number of organizations," Smith says. "I think one of the primary benefits that we have in these collaborative opportunities is to ensure that we are collectively building a capable and diverse pipeline of talent to solve for these problems and provide them with access to experiencing all of the benefits of our ecosystem."

With CEA specifically, some of these collaborations include working with Greentown Houston, which is just next door to the program's home at The Ion, and the Greater Houston Partnership's Houston Energy Transition Initiative.

"We're a cog in the wheel. We do really well with that. We play well with others – in ways that the founder has a good experience and can benefit," Smith says.

Smith shares more about what she's looking for in the second cohort of CEA on the podcast episode, as well as what she sees as Houston's role in the energy transition. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Juliana Garaizar has a new role within Greentown Labs. She's lead the local team as launch director, and now is taking a new role now that Greentown Houston has opened its doors. Garaizar recently discussed with InnovationMap why now is the perfect time for Greentown to premiere in Houston.

"I think that if Greentown had happened one year before or even one year later, it wouldn't be the right time. I really believe that our main partners are transitioning themselves — Shell, Chevron, and many others are announcing how they are transitioning," she says. "And now they look at Greentown as an execution partner more than anything. Before, it was a nice initiative for them to get involved in. Now, they are really thinking about us much more strategically." Click here to read more.

Electronics manufacturer and MacroFab, run by CEO Misha Govshteyn, much like the rest of the business world, was not immune to the effects of the pandemic. But as some business returned last summer, Govshteyn says MacroFab bounced back in a big way.

"In a lot of ways, the concepts we've been talking about actually crystalized during the pandemic. For a lot of people, it was theoretically that supply chain resiliency is important," Govshteyn says on this week's episode of the Houston Innovators Podcast. "Single sourcing from a country halfway around the world might not be the best solution. ... When you have all your eggs in one basket, sooner or later you're going to have a break in your supply chain. And we've seen nothing but breaks in supply chains for the last five years."

UH study uncovers sustainable farming methods for hemp production

growth plan

A new University of Houston study of hemp microbes can potentially assist scientists in creating special mixtures of microbes to make hemp plants produce more CBD or have better-quality fibers.

The study, led by Abdul Latif Khan, an assistant professor of biotechnology at the Cullen College of Engineering Technology Division, was published in the journal Scientific Reports from the Nature Publishing Group. The team also included Venkatesh Balan, UH associate professor of biotechnology at the Cullen College of Engineering Technology Division; Aruna Weerasooriya, professor of medicinal plants at Prairie View A&M University; and Ram Ray, professor of agronomy at Prairie View A&M University.

The study examined microbiomes living in and around the roots (rhizosphere) and on the leaves (phyllosphere) of four types of hemp plants. The team at UH compared how these microorganisms differ between hemp grown for fiber and hemp grown for CBD production.

“In hemp, the microbiome is important in terms of optimizing the production of CBD and enhancing the quality of fiber,” Khan said in a news release. “This work explains how different genotypes of hemp harbor microbial communities to live inside and contribute to such processes. We showed how different types of hemp plants have their own special groups of tiny living microbes that help the plants grow and stay healthy.”

The study indicates that hemp cultivation can be improved by better understanding these distinct microbial communities, which impact growth, nutrient absorption, stress resilience, synthesis and more. This could help decrease the need for chemical inputs and allow growers to use more sustainable agricultural practices.

“Understanding these microorganisms can also lead to more sustainable farming methods, using nature to boost plant growth instead of relying heavily on chemicals,” Ahmad, the paper’s first author and doctoral student of Khan’s, said the news release.

Other findings in the study included higher fungal diversity in leaves and stems, higher bacterial diversity in roots and soil, and differing microbiome diversity. According to UH, CBD-rich varieties are currently in high demand for pharmaceutical products, and fiber-rich varieties are used in industrial applications like textiles.
