Like many successful operations, Greentown Labs, a climatetech incubator based in Somerville, Massachusetts, outside of Boston, had its humble beginnings.

"Greentown is one of those things where a business seems obvious in retrospect," says Jason Ethier, a serial energy entrepreneur, on this week's episode of the Houston Innovators Podcast.

He says he and a few other founders were working on their various ventures in a building that ended up getting slated for demolition, forcing them to find a new place to set up shop.

"We were all building stuff within energy and technology," Ethier remembers. "We had to find a new building, and the landlord looked at us and said, 'I don't want to deal with a bunch of small companies. I want one company, one check, and one lease."

The group of entrepreneurs formed Greentown as a way to make the rent work, but they started attracting interest from other founders who wanted in. The organization evolved to what it is today — a dual-located energy incubator that's supported over 500 companies that have raised over $4 billion in funding.

Ethier, whose startup at the time brought him to Houston frequently, recognized the same scrappy founder mentality and need for incubation support in the Bayou City and was a key player in expanding Greentown to Houston in 2021.

"Every city is proud of who they are, but I think Houston especially is a city that likes to solve problems and build things locally," Ethier says. "When presented the opportunity to help build and ecosystem here, members of the ecosystem raised their hands and said, 'how can I help.'"

Juliana Garaizar, who was hired as launch director for Houston and now is head of Greentown Houston, tapped Ethier to support the expansion into town. Now, as senior director of membership at Greentown Labs, he works hands on with startups at Greentown.

He's taken his knowledge as a serial entrepreneur and incubation leader to launch the EnergyTech Startups podcast with co-host Lara Cottingham, the vice president of strategy, policy, and climate impact at Greentown Labs.

"As an entrepreneur, sometimes you feel a gap in the market in your bones and you just have to do something about it," Ethier says, explaining that he observed that when meeting people, he realized Houston got a bad rap. "Houston isn't viewed as a cool place to build a company if you don't know how good it is to be here."

The other thing Ethier says he realized was that Houston founders were understated in what they accomplished. So, he set out to start a podcast that would shine the spotlight on a Houston energy entrepreneur on a regular basis. The show, launched last fall, das now introduced listeners to over 20 energy founders and is continuing to do so on a biweekly basis.

Ethier shares more on his views of the future of Houston as an energy transition leader on the show. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

5 Houston innovators who made headlines in August 2025

Featured Innovators

Editor's note: Innovators hailing from both Rice University and University of Houston made headlines in August by developing a new biomaterial that could replace plastic and deploying a new flood scale to help Houstonians stay safe. Plus, one local innovator has a big move on the horizon.

Here are five Houston innovators to know right now.

Collaborators from two Houston universities are leading the way in engineering a biomaterial into a scalable, multifunctional material that could potentially replace plastic. The research was led by Muhammad Maksud Rahman, an assistant professor of mechanical and aerospace engineering at the University of Houston and an adjunct assistant professor of materials science and nanoengineering at Rice University. M.A.S.R. Saadi, a materials science and nanoengineering doctoral student at Rice University, was first author on the study. The study introduced a biosynthesis technique that aligns bacterial cellulose fibers in real-time, which resulted in robust biopolymer sheets with “exceptional mechanical properties,” according to the researchers.

University of Houston Professor of Psychology Steven Paul Woods and doctoral student Natalie C. Ridgely recently partnered with the Space City Weather (SCW) blog to create a new flood alert scale for the trusted weather site. “My lab does work on how people access, understand, and use health information, so I thought we could adapt some of that ongoing work and our expertise in psychological science to answer questions about weather communication, and help keep Houstonians informed and safe,” said Woods.

Rice biotech studio secures investment from Modi Ventures, adds founder to board

fresh funding

RBL LLC, which supports commercialization for ventures formed at the Rice University Biotech Launch Pad, has secured an investment from Houston-based Modi Ventures.

Additionally, RBL announced that it has named Sahir Ali, founder and general partner of Modi Ventures, to its board of directors.

Modi Ventures invests in biotech companies that are working to advance diagnostics, engineered therapeutics and AI-driven drug discovery. The firm has $134 million under management after closing an oversubscribed round this summer.

RBL launched in 2024 and is based out of Houston’s Texas Medical Center Helix Park. William McKeon, president and CEO of the TMC, previously called the launch of RBL a “critical step forward” for Houston’s life sciences ecosystem.

“RBL is dedicated to building companies focused on pioneering and intelligent bioelectronic therapeutics,” Ali said in a LinkedIn post. “This partnership strengthens the Houston biotech ecosystem and accelerates the transition of groundbreaking lab discoveries into impactful therapies.”

Ali will join board members like managing partner Paul Wotton, Rice bioengineering professor Omid Veiseh, scientist and partner at KdT Ventures Rima Chakrabarti, Rice alum John Jaggers, CEO of Arbor Biotechnologies Devyn Smith, and veteran executive in the life sciences sector James Watson.

Ali has led transformative work and built companies across AI, cloud computing and precision medicine. Ali also serves on the board of directors of the Drug Information Association, which helps to collaborate in drug, device and diagnostics developments.

“This investment by Modi Ventures will be instrumental to RBL’s growth as it reinforces confidence in our venture creation model and accelerates our ability to develop successful biotech startups,” Wotton said in the announcement. "Sahir’s addition to the board will also amplify this collaboration with Modi. His strategic counsel and deep understanding of field-defining technologies will be invaluable as we continue to grow and deliver on our mission.”

New peer-to-peer grocery app launches in Katy with plans to expand

local goods

If computer scientist and mobile applications developer Arfhan Ahmad has his way, his burgeoning Houston-based startup, QuickPantri, will be directly responsible for adding to the definition of what it truly means to be neighborly.

“Fast delivery from next door” — that’s the tagline for Ahmad’s hyperlocal grocery platform, which focuses on solving last-mile access, neighborhood commerce and food affordability.

“I’m passionate about combining technology with real-world problems, especially those that impact working families and underserved communities,” Ahmad says. “I moved to Houston two years ago, and here I realized that grocery stores are far from the neighborhoods.”

Ahmad envisions QuickPantri will help people who need grocery items urgently, sparing them a trip to the store or costly delivery fees by letting them source items directly from their neighbors’ cupboards.

With his new peer-to-peer app, members — especially those tethered to their residence due to disability or immobility or those unable to make grocery runs with children in tow — can simply log on to QuickPantri and purchase grocery items from their own neighbors.

“My initial thought was, 'What if we have an app that allows people to open a grocery store at their own home and sell any essential items to other neighbors?'” Ahmad says. “So, after having this idea in my mind, I asked my neighbors, 'If I sell groceries from my home, would you buy them from me?' And most of them gave me positive responses. After doing some surveys online on the Nextdoor app and Facebook, I started building this app.”

And like a good neighbor, Ahmad launched QuickPantri in his own neighborhood in Katy.

He then looked at scaling, first by securing approvals from Harris County to sell pre-packaged grocery items from his home. The response exceeded his own expectations. In the last two months, Ahmad estimates that he has delivered to 250 homes in the Katy area. Ahmad has seen that most customers use the app in search of late-night snacks and drinks.

“Ninety-five percent of those orders were delivered in 15 to 30 minutes … Our plan is to expand in other high-risk communities and other cities,” Ahmad says.

To date, Ahmad has obtained approvals from Arizona, Utah and Nevada.

He’s in the process of launching version two. Starting September 1, other sellers will be able to join the app and apply to sell goods to their neighbors. Ahmad says he currently has 50 sellers on the waitlist.

Each seller is allotted a potential selling radius of 10 minutes to ensure swift delivery. Also, sellers are required to deliver the goods via bicycle or on foot, making QuickPantri a pollution-free delivery option.

Currently, the app only sells pre-packaged items and sellers are required to show the expiration date in photos. The app utilizes AI to check pricing for goods in the area, and Ahmad says the app typically lists prices lower than what AI predicts.

Outside of geographic reach and number of buyers and sellers, Ahmad also hopes to expand the list of items that can be sold on the app to include clothes, electronics and cleaning supplies.

“We want our seller to be the ultimate source,” Ahmad says.
