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."

Houston-founded startup launches new COVID-19-focused sanitizing services

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.

Validere

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.

Intelligent Implants

Recent graduate of the Texas Medical Center's TMCx medical devices program, Intelligent Implants created a technology that stimulates bone growth following corrective back surgery.

The Houston startup closed a funding round in October with two investors, according to Crunchbase. The total raise was reported as a $1 million Mezzanine round on AngelMD.

Saranas

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.

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.

What to expect from the inaugural TiECon Texas event this week

where to be

Innovators and entrepreneurs will gather in Houston this week to show off their latest advancements in automation during the first-ever TiECon Texas conference at the Ion District.

“Automation is not simply changing how we work. It is redefining how value is created across every industry,” Somesh Singh, president of TiE Houston, said in a release. “Texas has the talent, the infrastructure, and the entrepreneurial spirit to lead this transformation. TiEcon Texas 2026 is where the people building that future will come together to shape it."

The Indus Entrepreneurs (TiE) started in Silicon Valley in 1994 as a two-day seminar, but has grown into a worldwide network of events celebrating technological advancement. TiECon in Houston is a merger of the TiE networks across Texas for one large-scale event taking place at the Ion on Wednesday, October 28, and Thursday, October 29. Tickets are available here.

The event includes a partnership with Hatch Pitch, a founder-first startup showcase that has raised over $20 billion in funding for new companies in the tech industry. Participants will come from industries like space exploration, healthcare, energy, and the AI sector to present their ideas in front of an investor network for possible development.

“Over 80 percent of the teams we have coached have gone on to receive funding,” Greg Wright, founder of Hatch Pitch, added in a release.

In addition, there will be forums and talks on a variety of automation subjects, everything from robotic surgery to automation in government. Educators from Baylor College of Medicine, UTHealth Houston, and the University of Houston plan to discuss the raising of children in a world with extensive artificial intelligence integrated into so many areas. Steven Kean, President and CEO of the Greater Houston Partnership, will give the keynote speech on the Bayou City’s place in these emerging technological spheres.

Singh highlighted how the large-scale disruptions in the technological status quo by the rise of AI could be a sign of potential growth and innovation. The entrepreneurs presenting at TiECon may be the ones to harness the sometimes unsteady AI industry for good causes.

“History shows that periods of technological disruption create extraordinary opportunities for those prepared to act,” he said. “TiEcon Texas is designed to help founders, investors, and enterprises understand where the automation economy is headed and how to participate in building it."

Here are the 10 startups pitching during the TiE Hatch Pitch competition:

Houston startup makes Time's list of the best inventions of 2026

Innovation Station

One of the year's most buzzworthy innovations comes from a Houston-based leader in the energy transition. Utility Global's H2Gen recently made Time magazine’s list of the 300 best inventions of 2026.

The H2Gen is an innovative system that produces low-cost clean hydrogen from water and industrial off-gases. The company says the process doesn’t require electricity, a notable claim since hydrogen production typically consumes a lot of power.

"Using a tubular electrochemical cell containing a proprietary electrolyte and water, the company can turn industrial off-gases into hydrogen at scale—no extra electricity required," writes Time. "Bonus: the process also pulls out carbon dioxide as a separate stream, where it can be captured and kept out of the atmosphere.

CEO Parker Meeks tells Time, it's “a practical pathway to decarbonize existing industrial assets."

The startup is on a roll. It has raised $100 million so far in an ongoing Series D round to offer its decarbonization technology at industrial scale around the world.

H2Gen is joined by 10 other inventions with Texas connections onTime's list, as well as one "special mention."

In North Texas, they are:

Samsung
Plano-based Samsung Electronics America pulled off a hat trick this year, with three products making Time’s list. First up is the Galaxy S26 Ultra smartphone. It packs a more powerful camera, Galaxy AI features, and pro-level content creation tools. But Time singled out its new built-in privacy display as the phone’s “biggest selling point.”

Samsung’s Bespoke AI Family Hub refrigerator also got smarter. When AI first came to the Family Hub in 2024, it could recognize some fresh foods, but you still had to log packaged items by hand, Time noted. Now, with Google Gemini built in, the fridge can identify more than 2,000 packaged foods, read handwritten labels, and warn you when food is about to expire. It then uses what’s inside to build grocery lists and suggest recipes.

And for gamers, there’s the Odyssey G8 monitor. Its 6K resolution leapfrogs the 4K standard, delivering what Samsung calls “exceptional visual clarity and detail” on a screen big enough for gaming and multitasking.

OxeFit
Plano-based OxeFit’s XS1 Peak is about the size of a treadmill but works like an entire gym. It can be set up for strength training, simulated skiing or kayaking, Pilates, or rowing. What makes it stand out is a built-in virtual spotter. According to Time, the machine “uses AI, computer vision and sensors to correct the user’s form, change resistance in the middle of a rep and reduce the weight when the user is struggling, much like a human spotter.”

EssilorLuxottica
EssilorLuxottica, the French eyewear giant whose U.S. headquarters is in Farmers Branch, makes Essilor Stellest lenses. The lenses correct nearsightedness while also slowing the eye growth that makes it worse over time. Stellest is the first and only eyeglass lens authorized by the U.S. Food and Drug Administration to control myopia, Time said. The lenses look like regular glasses but contain 1,021 tiny lenslets. In a U.S. trial of kids ages 6-12, myopia progression slowed by an average of 71 percent over two years compared with standard lenses.

Helpany
Helpany, a startup based in Phoenix that manufactures its devices in DFW, makes Paul, a ceiling-mounted gadget that uses radar and AI to spot subtle changes in how residents move and flag those at higher risk of falling. Helpany says the technology can cut falls by as much as 72 percent.

Aurora Innovation
Aurora, based in Pittsburgh with a corporate and operations hub in Coppell, rolled out its second-generation Driver 2 system in July. By September, Driver 2 trucks had logged more than 500,000 driverless miles without a single at-fault crash, Time reported, and the company expects 200 of them on the road by the end of 2026.

Colossal Biosciences
Dallas-based Colossal Biosciences built an artificial egg by placing an ultra-thin, transparent silicone membrane inside a rigid 3D-printed cup, letting scientists watch the embryo develop. Twenty-six chickens have already been hatched.

In Austin, they are:
Cedar Park-based Hyliion landed on Time’s list with its Karno Power Module, a modular generator designed to produce power wherever it’s needed. The Karno represents a big pivot for the company. Hyliion got its start building electrified powertrains for 18-wheelers before shifting into power generation after acquiring the Karno generator technology from GE Aerospace. Founded in Pittsburgh in 2015, the company relocated to Cedar Park in 2018.

The other Austin-associated honoree is Moment Energy. As more electric vehicles hit the road, a growing number of their batteries are nearing retirement, while demand for power keeps climbing. Moment Energy found a way to tackle both problems at once. The company’s Megafactory 1, which opened in Vancouver, Canada, in June, turns old EV batteries into modular energy storage systems for hospitals, factories, data centers, and other big power users. “Our goal is to make sure these batteries don’t end up in landfills,” founder Edward Chiang told Time.

In the “Special Mentions” category, Austin-based Renzoe Box gained notice for its refillable custom makeup palette for on-the-go people. Licensed architect René Graham designed the box. She graduated from Houston's Rice University, and was born and raised in Dallas.

The company has also developed AI products for sinus disease detection and 3D organ reconstruction.

CEO Jim Havelka founded the company in 2017. It is participating in the Mayo Clinic Accelerate Platform. It has raised about $4 million in seed funding and has received numerous non-dilutive grants from the National Science Foundation, the National Institutes of Health and the Cancer Prevention and Research Institute of Texas. The company shared in its application that it plans to launch a Series A fundraising round and submit an FDA 510K application for its organ reconstruction product, Voluquant, by the end of 2026.

Prana Surgical

Prana Surgical is developing a minimally invasive surgical platform for small, hard-to-reach lung nodules that may be cancerous. The company's Prana System cleared U.S. Food and Drug Administration (FDA) approval earlier this year.

Prana Surgical was originally founded as Prana Thoracic in 2022. It has participated in numerous accelerators, including the Texas Medical Center Innovation Accelerator in 2023 and the IGNITE Health accelerator in 2022. It raised $6 million in Series A funding rounds in 2023 and 2024 , with a Series B currently ongoing. The company said in its application that it is currently moving into the next stage of clinical validation and revenue generation in the U.S., in addition to preparing its manufacturing and commercial infrastructure for broader use.

Skybound MedTech

Skybound MedTech develops technologies that aim to address the health risks of long-duration spaceflight. Its compact, miniaturized medical technologies can deliver complex therapies without a physician.

CEO Matthew Kuhn, who previously founded Taurus Vascular, founded Skybound last year. The company emerged from stealth in January after raising a $1.25 million Series A round. It plans to advance its lead dual-use platform into critical preclinical validation in November, the company shared in its application. It is currently raising a $25 million Series A round and is pursuing federal research partnerships with DARPA and ARPA-H.
