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.

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 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.

Restaurant-driven app focuses on Houston's food scene

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.

Houston company creates portable device that eases pain without the use of drugs

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.

Houston software startup pivots to provide digital networking solutions

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.

Houston doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
