One of the dozen or so Houston startups kicking of the new year with fresh funding is SmartAC.com, a company that's designed a platform that enables contractors in the HVAC and plumbing industries to monitor, manage, and optimize their maintenance memberships through advanced sensors, AI-driven diagnostics, and proactive alerts.

Last month, the SmartAC.com raised a follow-on round with support from local investor Mercury to continue growth and expansion of the product, which has evolved on many ways since the company launched in 2020, emerging from stealth with $10 million raised in a series A. In a May 2023 interview for the Houston Innovators Podcast, Founder and CEO Josh Teekell explained how he embraced the power of a pivot.

The company's sensors can monitor all aspects of air conditioning units and report back any issues, meaning homeowners have quicker and less costly repairs. While SmartAC.com started with providing the service and tech to homeowners directly, Teekell says he's had a greater interest in working with plumbers and HVAC companies who then deploy the technology to their customers.

"It became quite evident that homeowners don't care about air conditioning really at all until their system breaks," Teekell says on the show. "The technology is really built around giving those contractors as another way to gain a customer relationship and keep it."

Revisit the podcast episode below where Teekell talks about SmartAC.com's last raise.

SmartAC.com's previous round in 2023 — a $22 million series B — was used grow its team that goes out to deploy the technology and train the contractors on the platform.

"We've been very fortunate to get some of the biggest names in Houston on our cap table," Teekell says in the May 2023 conversation. "Since we're raising a bunch of money locally, everyone understands what a pain air conditioning can be."

Houston-based startup secures fresh funding led by local investor to expand HVAC, plumbing platform

money moves

Houston-based SmartAC.com, which provides a customer loyalty management platform for contractors, has raised a follow-on round from Mercury Fund and other investors. The dollar amount of the round wasn’t disclosed.

An October filing with the U.S. Securities and Exchange Commission (SEC) indicates SmartAC.com planned to raise $8.2 million in venture capital. Of that sum, about $4 million had already been raised, the company reported, and nearly $4.2 million remained to be raised.

SmartAC.com's platform enables contractors in the HVAC and plumbing industries monitor, manage, and optimize their maintenance memberships through advanced sensors, AI-driven diagnostics, and proactive alerts.

“Growing a business in the trades is all about customer loyalty, and loyalty is driven by optimizing the customer’s experience,” Josh Teekell, founder and CEO of SmartAC.com, says in a news release. “SmartAC.com was built to perfect the experience of home comfort through data-driven insights that bring long-term value to homeowners and contractors alike.”

SmartAC.com says the new funding will enable expansion of its platform.

“Amid rising consumer demand for ‘smart home’ innovations, SmartAC.com is addressing a critical need for more sophistication in HVAC and plumbing through a technology-driven strategy,” says Heath Butler, a partner at Mercury Fund.

In 2020, SmartAC.com emerged from stealth mode and announced a $10 million series A round. The company raised a $22 million series B round in 2023.

Podcast: Houston home tech startup raises $22M to grow sales

HOUSTON INNOVATORS PODCAST EPISODE 184

A Houston startup that combines unique sensor technology with software analysis has raised its next round of funding to — according to Founder and CEO Josh Teekell — turbocharge its sales.

SmartAC.com launched in 2020, emerging from stealth with $10 million raised in a series A. Over the past almost three years, the company has firmed up its hardware, developed its software, and pivoted slightly from selling directly to consumers to adopting a B2B approach.

The company's sensors can monitor all aspects of air conditioning units and report back any issues, meaning homeowners have quicker and less costly repairs. While SmartAC.com started with providing the service and tech to homeowners directly, Teekell says he's had a greater interest in working with plumbers and HVAC companies who then deploy the technology to their customers.

"It became quite evident that homeowners don't care about air conditioning really at all until their system breaks," Teekell says on the Houston Innovators Podcast. "The technology is really built around giving those contractors as another way to gain a customer relationship and keep it."

Now, Teekell says he's focused on turbocharging sales to these contractors, and he's going to do that with the funding raised in the series B round that closed this month. He says the company will also grow its team that goes out to deploy the technology and train the contractors on the platform.

"This funding really buys us a couple years of runway through the end of next year and allows us to focus on getting to cash flow breakeven, which is right around our wheelhouse of our abilities here in the next 12 months," Teekell says. "In general, we've accomplished everything we'd be able to accomplish on the hardware side, and now it's just about deployment."

The $22 million SmartAC.com has raised came from local investors. Teekell, who hasn't announced the full list of the round's investors, explains that while traditionally startups might have more opportunity on the coasts for raising money, it's not hard to sell Houstonians on the benefits of SmartAC.com's optimized air conditioning.

"We've been very fortunate to get some of the biggest names in Houston on our cap table," Teekell says. "Since we're raising a bunch of money locally, everyone understands what a pain air conditioning can be."

The Bay Area and New York regions don't have the same air conditioning problems, Teekell says, so raising funding in those areas was challenging.

"Our overall vision as a company is to perfect the experience of home comfort," Teekell says.

He shares more on how he hopes to accomplish this vision on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

It can get hot as Hades in Houston during the summer, and a new Houston startup is using machine learning and technology to ensure that users can count on their air conditioning units to stay up and running during the heat.

Houston-based SmartAC.com has emerged from stealth mode with $10 million in funding from a series A investment round. The company's technology focuses on maintaining air conditioning and heating (HVAC) health before a major service issue occurs.

"Over 70 million homes have central air in the U.S., making indoor comfort a regular way of life. People don't often think about their HVAC systems, taking it for granted, until the day the AC or heat goes out," says Josh Teekell, CEO and founder of SmartAC.com, in a news release. "These systems require regular upkeep, and when they aren't maintained, costs can get out of hand. SmartAC.com's offer is simple; we care about your AC so you don't have to."

The company's technology combines three hardware sensors — which users can install themselves — and machine learning software to analyze data to predict service issues. The comfort sensor monitors the temperature of the air coming out of the unit, the filter sensor tracks the lifespan of air filters by tracking pressure and airflow, and the water sensor protects against leaks and clogs.

All three sensors are linked by SmartAC.com Hub, which sends data from the sensors to the cloud and the SmartAC.com app to translate the data into recommendations to help users reduce costs and get ahead of issues.

"The average AC replacement cost is $7,500 — an expense that can be a huge burden on homeowners. Caring for these assets is inconvenient and oftentimes confusing, resulting in 80 percent of homeowners skipping the recommended maintenance on their AC systems," says Andrew Fuselier, SmartAC.com's COO, in a news release. "It's time to digitize the AC ownership experience to solve a decades old problem. SmartAC.com was formed in stealth mode with feedback from thousands of homeowners, so we're thrilled to finally show the world what we've built."

In addition to working directly with consumers, SmartAC.com has teamed up with HVAC service providers.

"SmartAC.com is a total game-changer," says David Lewis of Mission AC in a news release. "Our clients love the additional transparency and the technology allows us to improve our service speed and quality because, for the first time, we have real-time data on the systems we service."

Houston health tech co. lands NIH grant for AI cancer prediction tool

fresh funding

Houston-based CellChorus and Stanford Medicine were recently awarded a Phase I Small Business Innovation Research grant for the company's AI platform to test how certain cancer patients will respond to therapies.

The funding comes from the National Cancer Institute of the National Institutes of Health. According to a filing, the grant totaled just under $400,000.

CellChorus, which spun out from the University of Houston’s Technology Bridge, has developed TIMING (Time-lapse Imaging Microscopy In Nanowell Grids), which analyzes the behavior of thousands of individual immune cells over time and can identify early indicators of treatment success or failure.

The company will work with Stanford's Dr. David Miklos and Dr. Saurabh Dahiya, who have built the Bone Marrow Transplantation and Cell Therapy Biobank. The biobank manages and stores biological samples from patients treated at their clinic and in clinical trials.

"Predicting which patients will achieve durable responses after CAR-T therapy remains one of the most important challenges in the field,” Miklos said in a news release. “We aim to uncover functional cellular signatures that can guide treatment decisions and improve patient outcomes.”

The project will specifically profile cells from patients with relapsed/refractory large B-cell lymphoma (r/rLBCL). According to CellChorus, only about half of r/rLBCL patients who receive CAR-T therapy "achieve a durable, long-term remission." Others do not respond to therapy or experience relapse.

“The sooner we know whether a cancer therapy is working, the better. To maximize patient benefit, we need technology that can provide a robust and early prediction of response to therapy. The technology needs to be scalable, cost-efficient, and capable of rapid turnaround times,” Rebecca Berdeaux, chief scientific officer of CellChorus, added in the release. “We are excited to work with Drs. David Miklos and Saurabh Dahiya and their colleagues on this very important project.”

CellChorus has previously received SBIR grants from federal agencies, including a $2.5 million award in 2024 from its National Center for Advancing Translational Sciences (NCATS) and a $2.3 million SBIR Fast-Track award from the National Institute of General Medical Sciences in 2023.

Houston museum showcases America's founding documents in rare exhibit

Experience History

As the United States prepares to celebrate its 250th birthday, Houstonians have a chance to see rare documents from the founding of the nation. Freedom Plane National Tour: Documents That Forged a Nation, presented by the National Archives Foundation, will be on display at the Houston Museum of Natural Science through Monday, May 25.

The collection includes a rare engraving of the original Declaration of Independence; official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton; a draft of the Bill of Rights; the Treaty of Paris, the documented that recognized America's independence from Great Britain; and the tally of votes approving the Constitution.

The National Archives specifically chose Houston as one of only eight cities in the country to host the exhibit as a means to help the documents reach a wider audience outside of the main hub of semiquincentennial events in New England and the Washington, D.C. area.

"One of the things we decided when we put the tour together because we wanted to be off the East Coast," said Patrick Madden, CEO of the National Archives Foundation, who was onsite for the exhibit's opening in Houston. "There's a lot of 250th celebration stuff happening in the original 13 colonies. How do we get it to major markets where larger numbers of people can see it? So in the case of Houston, obviously, [is a] major market in this part of the country, but also we've partnered with the museum twice before with National Archives exhibits, so we knew that they would be up to the task of handling the exhibit and the crowds."

The star of the collection is a rare engraving of the original Declaration of Independence. Secretary of State and future president John Quincy Adams commissioned 200 exact replicas of the document from engraver William J. Stone in 1823. Less than 50 now remain. Madden joyfully pointed out that there are errors in this document, a potent reminder that the men who forged a nation made mistakes.

"There's a couple of typos in it where they had to make corrections," said Madden. "So even the founders, you know, they're all human. That resonates because here these people are making this move against the most powerful nation in the world and putting their lives on the line for a country based on ideas."

Other impressive parts of the collection include official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton, as well as one of the drafts of the Bill of Rights. Many states would not ratify the Constitution until certain rights were included in the document, leading to Washington going on a national tour assuring state leaders enshrining protections was first on the list. The draft copy on display specifically shows the First Amendment in progress.

Houston is the fourth stop on the exhibition's tour, which will take the documents to Denver, Miami, Dearborn, and Seattle through the summer. Freedom Plane is just one part of a larger patriotic celebration at the HMNS, which includes a film series celebrating American science and culture and general Americana decoration throughout the main hall.

Admission to Freedom Plane is free to the public, but separate from general admission to the museum. Space is limited, and passes are available on a first-come, first-serve basis. Non-members should expect long waits or the possibility that the day's passes are sold out. Only museum members can reserve passes for specific times. Flash photography is prohibited due to the fragile nature of the documents.

Houston quantum energy chip startup emerges from stealth with $12M round

seed funding

Houston-based Casimir has emerged from stealth with a $12 million seed round to commercialize its quantum energy chip.

The round was led by Austin-based Scout Ventures. Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Tim Draper of Draper Associates also participated in the round. The oversubscribed round exceeded the company’s original $8 million target, according to a news release.

Casimir’s semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company plans to commercialize its first-generation MicroSparc chip by 2028.

The MicroSparc chip measures 5 millimeters by 5 millimeters and is designed to produce 1.5 volts at 25 microamps, comparable to a small rechargeable battery, without degradation and no replacement cycle.

“Casimir represents exactly the kind of breakthrough dual-use technology Scout Ventures was built to back,” Brad Harrison, founder and managing partner at Scout Ventures, said in the release. “This is based on 100 years of science and we’re finally approaching a commercial product … We’re proud to lead this round and support Casimir’s journey from applied science to deployed technology.”

Casimir says it aims to scale its technology across the ”full power spectrum,” including large-scale energy systems that can power homes, commercial infrastructures and electric vehicles.

Casimir's scientific work has been supported by DARPA-funded nanofabrication research and its technology was incubated at the Limitless Space Institute (LSI). LSI is a nonprofit that works to innovate interstellar travel and was founded by Kam Ghaffarian. Technology investor and serial entrepreneur Ghaffarian has been behind companies like X-energy, Intuitive Machines, Axiom Space and Quantum Space.

Harold “Sonny” White, founder and CEO of Casimir, believes the technology can power devices for years without replacements.

“Millions of devices will operate for years without a battery ever needing to be replaced or recharged because we have engineered a customized Casimir cavity into hardware capable of producing persistent electrical power,” White added in the release. “I spent nearly two decades at NASA studying how we power humanity’s future. That work led me to the Casimir effect and the quantum vacuum, where new tools have allowed us to build on a century of scientific knowledge and bring abundant power to the world.”
