A Houston-founded startup that designed an app-based service for apartment dwellers has closed an $8 million series A led by Houston-based Mercury Fund.

Spruce, which was founded in Houston in 2016 as Apartment Butler before rebranding and relocating to Austin, announced the close of its latest round this week. The startup partners with multifamily companies to provide concierge-like services, such as cleaning, dog walking, and even COVID-19 sanitation.

"Spruce is changing how people live in their homes," says Ben Johnson, founder and CEO, in a news release. "Today's apartment community is a vibrant micro-economy for services and goods, and Spruce efficiently channels these interactions into a single marketplace. This Series A will expand our offerings to more residents and properties as well as continue our national roll-out."

Mercury Fund also invested in the company's seed round last year, and since that funding, Spruce has expanded out of state and into nine new markets. According to the release, the company, which still has an office in houston, has 40 employees and over 760 properties with 230,000 units on its platform.

"Spruce has perfected their market model and built a best-in-class team. Their resilience and growth during this unprecedented time have impressed us, and we are excited to continue on this journey with them," says Blair Garrou, managing director at Mercury Fund, in the release.

Houston-based Sweat Equity Partners, a new Spruce investor, also contributed to the round. Andrew White, president of the investment group, will also join the board of directors.

"Spruce is building a valuable platform focused on delivering outstanding home services under the unique requirements of the multi-family segment," says White in the release.

Steven Pho, an Austin-based entrepreneur and investor previously with Favor Delivery and RetailMeNot, will also join the board.

"Spruce has an amazing opportunity to quickly and cost effectively reach a mass market through their partnerships with national property managers," Pho says in the release. "This unique channel strategy differentiates Spruce from their competitors and enables them to rapidly achieve scale and density in new markets."

keeping clean

A startup that provides concierge services — like cleaning and dog walking — to apartment renters has expanded its services to outside the apartment units to help multifamily properties with sanitization and disinfection services to protect their communities from COVID-19.

Austin-based Spruce, which was founded in Houston in 2016 and still has an office locally, has a new suite of services for disinfecting common areas — like leasing offices, hallways, mail rooms, etc. — using EPA-compliant chemicals.

"Now, more than ever, it is critical for apartment communities to make sure their common areas are regularly decontaminated and disinfected to help slow the spread of the coronavirus and to prevent as many infections as possible," says Ben Johnson, founder and CEO of Spruce, in a statement.

The services include a weekly disinfectant of high-touch spots — like door handles and elevator buttons — as well as a weekly comprehensive cleaning that involves mopping, surface cleaning, and vacuuming. The startup also offers a bimonthly fogging service that can completely cover both indoor and outdoor areas with disinfectant. This solution can protect surfaces for months, according to the news release.

"This is an unprecedented public health crisis, and we worked closely with our clients to determine the biggest need and hope these services will give apartment communities one more weapon to use in the fight against COVID-19 and will help give both operators and their residents peace of mind," Johnson continues in the release.

Spruce still offers its usual suite of services for individual apartment units such as daily chores and housekeeping and pet care, but extra precautions have been added since the coronavirus outbreak. The service providers are required to go through temperature checks before entering the properties. They also wear gloves, changing them out between units, and are incorporating paper products when able.

Since its founding, Spruce, which used to be called Apartment Butler, has expanded throughout the state and into South Florida, Denver, and Salt Lake City. Spruce has raised over $6 million in venture capital, per Crunchbase data, and that includes funds from Houston institutions like Mercury Fund, the Houston Angel Network, and Fitz Gate Ventures, as well as Austin-based Capital Factory.

Houston startup rebrands, closes $3 million investment round, and plans first out-of-state expansion

Spruced up

A Houston startup that coordinates hospitality services — such as cleaning, dog walking, etc. — has recently cleaned up itself, with a fresh rebranding and new funds to further develop the company.

Spruce (née Apartment Butler) has closed a venture capital round at $3 million. Princeton, New Jersey-based Fitz Gate Ventures led the round with three Texas investors: Houston-based Mercury Fund, the Houston Angel Network, and Austin-based Capital Factory, which recently announced its Houston outpost.

The fresh funds will allow for Spruce to expand its services out of Texas for the first time. Denver will be the first non-Texas market for the company, according to a news release. The funds will also go toward sales, marketing, and software development scaling.

"We could not be more appreciative of the support from these outstanding investors," says Ben Johnson, founder and CEO of Spruce, in the release. "Since our founding, we have grown aggressively as more and more apartment communities have seen the demand for hotel-inspired services increase dramatically. We look forward to continuing our strategic, rapid growth with this funding that will play a critical role in that expansion."

Last month, Apartment Butler rebranded into Spruce to better represent the company and its market disrupting features, according to a news release.

"Since our inception just a few short years ago, we have experienced an incredible rate of growth, demonstrating the demand residents have for hotel-inspired services in their apartment homes," says Johnson in the June 25 release. "We believe the new Spruce brand name better connects with consumers and reflects the full range of services we have to offer."

Spruce's services include daily chores, housekeeping, pet care (dog walking, pet sitting, etc.), and laundry and dry cleaning. Spruce has a B-to-B-to-C model in which it works with apartment communities to broker partnership deals to reach their residents.

Late last summer, Johnson closed a $2 million seed round for his company and expanded the company to Austin, hinting at the out-of-state growth being in the near future for the startup.

Apartment Butler closed a $2 million seed funding round in October that was led by Houston-based Mercury Fund. The Houston startup partners with apartment communities to streamline services — like cleaning or dog walking — for residents.

Founder Ben Johnson recently spoke with InnovationMap about his career and the company. He says the company plans to launch in Austin this month and another market in March. Apartment Butler will also expand to microservices — smaller services that have only been available to the rich before.

The funding reportedly is being used to expand the company's footprint as well as make competitive hires.

Data Gumbo

Data Gumbo, a Houston company that provides blockchain technology as a service, overachieved when it closed its seed round in August 2018. The company closed with $1.35 million, which is $300,000 more than the goal.

Led by CEO Andrew Bruce, Data Gumbo has a viable product and is producing revenue, according to a release. The company launched a full implementation of its technology on a Diamond Offshore rig this fall, which made it the first commercial installation of industrial blockchain technology.

Among the investors was Houston-based Carnrite Ventures and Silicon Valley's Plug and Play, the release notes.

While based in Canada, Validere is using its recent raise to expand into the Houston market. The seed round closed in October with $7 million raised. The company's co-founder, Nouman Ahmad, told InnovationMap in a recent article that they are focusing on expanding the Houston office and are actively hiring.

"The goal in 2019 is to be at the same stage — in terms of customer success — in the U.S. market as we were at the end of 2018 in the Canadian market," Ahmad says.

Saranas Inc., a Houston-based medical device company, is currently in its clinical trials thanks to a $2.8 million Series C fund that closed in May 2018. The trials are focused on the company's key device, called the Early Bird Bleed Monitoring System, which is designed to detect and track bleeding complications related to endovascular procedures. These medical procedures treat problems, such as aneurysms, that affect blood vessels.

In a story for InnovationMap, Zaffer Syed, president and CEO of Saranas, says the clinical trials are crucial for receiving approval from the U.S. Food and Drug Administration. That approval is expected this year.

One night, Sumit Sikka was on a quest to find the best Moscow Mule in Santa Monica. He couldn't find anything helpful online, and when he finally did get a good recommendation, he was already done for the night.

It was through this experience that Sikka knew he wanted to make a restaurant finder app, but he wanted to do something different from Yelp or Google Reviews. On those platforms, a restaurant can get crushed by a bad review that provides false information. So, when he started getting the ball rolling on Crityk, he realized he needed to give the restaurants a voice. Read the full story here.

Many of the estimated 50 million Americans who suffer from chronic pain turn to drugs — including heavily abused opioids — to relieve their symptoms. Houston-based startup Portable Therapeutix LLC's drug-free solution to pain management seeks to put a dent in the market for prescription painkillers.

In 2018, Houston-based Portable Therapeutix introduced Squid Go, a portable device that's designed to ease the pain and swelling of sore joints and muscles. It's a follow-up to the company's Squid Compression, a pain management device launched in 2013 for patients at rehabilitation centers, hospitals, doctor's offices, and the like.

Several years ago, David Grimes had a business partner who played dirty. It wasn't until the trial that followed the business wrongdoing that Grimes discovered the man had a history of cheating companies out of money. Grimes envisioned a software service that used public information to research potential investors or associates before signing on the dotted line of a partnership.

"I wanted to find a tool that would alleviate that pain and that risk of doing business," Grimes says. "I couldn't find that tool." Read the full story here.

Most of Christopher Robart's 10-year career in oil and gas has been deliberate and calculated — researching the right startup to be involved in or finding the right buyer for a company he invested in. However, his actual start in the industry wasn't so intentional.

"I sort of fell into oil and gas after I got of college back in 2003," says Robart, who is the president of Ambyint USA. "Before that, I was involved in a few startup things — some digital and some not. I was always sort of an entrepreneur." Read the full story here.

3 Houston innovators to know this week

Who's Who

This week starts in one year and ends in the next, and InnovationMap has three inspiring entrepreneurs to lead you into 2019. All three are behind Houston startups that are planning for big growth in the upcoming year. So, read their stories and get familiar with their names and faces — they aren't going anywhere.

Ben Johnson, founder and CEO of Apartment Butler

Ben Johnson has his own master plan. He'd work as an oil and gas banker for a bit, establish himself, get his MBA, and then, when he was in his 40s, would start his own company. He wasn't wrong about his future as an entrepreneur, but he was off by the timeline.

Johnson started Apartment Butler a few years ago when he saw how apartment communities had the potential to provide streamlined access to resident elected services — such as cleaning or pet care. At the same time, apartment communities across the U.S. were looking to beef up their amenities. Now, Apartment Butler is expanding to its third and fourth markets early next year and is looking to provide more services to its users.

Scott Parazynski, CEO of Fluidity Technologies

There are Renaissance men and then there's Scott Parazynski. He's has spent 57 days in space, trained as a trauma surgeon, and climbed Mount Everest as a team physician for the Discovery Channel. His latest conquest is designing a drone controller based on movement in space. The device, called the FT Aviator, allows for one-handed piloting of drones and has the potential to affect the way unmanned vehicles are piloted across industries. As the CEO of Fluidity Technologies, he has big plans for what one-handed drone operation can do.

David Grimes, CEO and co-founder of Snap Diligence

Hell hath no fury like a businessman scorned. When a business partner ended up being a shady miscreant, David Grimes realized there wasn't a digital vetting tool where you can evaluate a potential associate. After thinking on the idea for a while, Grimes found a co-founder and a way to create an algorithm that can take public information and run it against a person. The company he created is called Snap Diligence.

Now, the tool has morphed into something else that's been unexpectedly in demand. Snap Diligence can find business connections through your already-established network of associates. It's this new feature the company is looking to expand in 2019.

7 Houston neighbors named to U.S. News' best places to live in 2026

Living Well

Several Houston suburbs have been crowned the best places to live in the U.S. for 2026, according to U.S. News & World Report. Sugar Land is the highest-ranked city in the Houston metro, and it ranks as the 10th best place to live in the country.

The annual list of Best Places to Live in the U.S. is designed to help readers make the most informed decisions when choosing where to settle down, using data from sources such as the U.S. Census Bureau, Department of Commerce, the Federal Reserve and the Bureau for Economic Analysis, as well as state and local sources.

For the 2026-2027 rankings, U.S. News featured 250 U.S. cities and ranked them across four livability indexes — quality of life, value, desirability, and job market — weighted by importance based on survey results of approximately 500 Americans. The rankings were also broken down state-by-state, as well as the best big, medium, and small cities overall.

Sugar Land is the No. 4 best places to live in Texas, and it soared into the No. 10 spot overall in the nation after ranking 16th last year. Sugar Land also ranks as the fourth-best mid-sized city to live in America for 2026-2027.

According to U.S. News, Sugar Land's median household income is far higher than the national average. Residents make $140,511 per year, while the average American household income is only $83,181.

Additionally, the $431,815 median home value in Sugar Land is also far greater than the $359,870 national average.

After ranking in the top 10 in the 2025 report, League City and Pearland now both rank outside the national top 10 for 2026. League City slipped from No. 6 to No. 13 this year, while Pearland dropped from No. 3 nationwide to No. 16.

These three Houston suburbs also boast highly desirable job markets for potential newcomers or current residents that want to start or change their career.

Houston proper, however, remains outside of the top 250 and is the 327th best place to live in the U.S., and it's the 60th best place to live in Texas.

Other cities in the greater Houston area that ranked among the top 100 include:

  • No. 28 – The Woodlands
  • No. 38 – Katy
  • No. 61 – Missouri City
  • No. 82 – Spring

The Lone Star State had a "strong showing" in the overall top 10 thanks to its "high affordability scores," a release said. Besides Sugar Land, three more popular Texas suburbs made the cut: Leander (No. 8) outside Austin and Dallas-Fort Worth suburbs Flower Mound (No. 3) and Frisco (No. 9).

"As prices of everyday goods continue to rise, consumers are considering affordability as a top priority when choosing a place to live," said U.S. News consumer lending analyst Erika Giovanetti. "While U.S. News’ consumer survey indicated that quality of life and affordability were close in importance, cost-of-living concerns resulted in many Americans putting what they can afford above their aspirations."

Houston researchers report promising first in-human trial for implantable cancer therapy

cancer breakthrough

When it comes to cancer remedies, the treatment can be as challenging for the body as its cause. But what if immunotherapy could be localized? That’s precisely what a Houston team may soon make a reality.

Rice University researchers, in partnership with MD Anderson Cancer Center, recently published their findings from the first in-human trial of an implantable cancer-fighting treatment in the journal Clinical Cancer Research. The paper details testing of AVB-001, encapsulated cells engineered to release interleukin-2 (IL-2)—a naturally occurring signaling protein that boosts immunity—in the peritoneal cavities of 14 patients. The goal is to avoid the toxicity usually experienced with less targeted treatments, as well as find a solution to IL-2s’ abbreviated half-lives.

“Traditional IL-2 therapy has shown potent antitumor activity, but its clinical use has been limited by severe side effects and delivery challenges,” Omid Veiseh, director of the Rice Biotech Launch Pad, professor of bioengineering at Rice and a senior author on the study, said in a press release. “This platform allows us to localize and sustain cytokine exposure directly where tumors reside while minimizing systemic toxicity.”

Serous ovarian carcinoma is especially well-suited to the use of AVB-001 because it tends to spread throughout the abdomen. After a minimally invasive laparoscopic procedure, patients implanted with the cells were noted to tolerate the treatment well. Half of the enrolled patients’ cancer was stabilized, with several among them reporting extended signs of benefit. No maximum tolerated dose was reached and there were no life-threatening events tied to the study.

If that sounds like less-than-earth-shaking results, this is only the beginning. The capsules were implanted for about one week because IL-2 activity drops off after that. The researchers now know that further testing should include either higher levels, repeated doses, or a combination thereof, in order to create stronger advances.

The team has already made early headway on this next step. Preclinical studies in nonhuman primates were not only tolerated well, but without added toxicity, the apes had consistent pharmacological effects.

“This is a foundational step,” Veiseh explained. “We now have evidence that the platform is safe, biologically active and potentially scalable. The next phase is optimizing dosing and exploring combination therapies to unlock its full clinical potential.”

The combination would also include a checkpoint inhibitor, which might improve AVB-001’s tumor-fighting power. “What is exciting is that we are not just delivering a drug, we are programming a microenvironment,” added Dr. Amir Jazaeri, professor of gynecologic oncology at MD Anderson, member of the Rice Biotech Launch Pad’s clinical advisory board and a senior author on the study. “This opens the door to combination strategies that could amplify immune responses in ways that have not been feasible before.”
