Houston-based medical device company Saranas has tapped a veteran of the healthcare industry as its new CEO.

Mike MacKinnon most recently was president and partner at Madison Ventures +, a private equity firm based in Greenwood Village, Colorado. The firm invests in companies in healthcare, real estate, finance, and other sectors.

Before joining Madison Ventures +, MacKinnon was CEO of Zidan Medical, a startup focused on treatment of airway lesions in patients with early stage lung cancer. He served in that role from 2019 to 2023.

Earlier, he was CEO of ROX Medical, a medical device company specializing in minimally invasive vascular therapy for patients with uncontrolled high blood pressure. He held that role from 2018 to 2019. He previously worked at Philips North America, Volcano, AtheroMed, Hansen Medical, Access Closure, and FoxHollow Technologies.

In a news release, Dan Wolterman, chairman of Saranas’ board and former president and CEO of Memorial Hermann Health System, calls MacKinnon “an accomplished executive with an impressive record of bringing disruptive technology to market, guiding strategy, and driving significant growth.”

Now president and CEO of Nashua, New Hampshire-based medical device company Conformal Medical, James Reinstein was president and CEO of Saranas from 2020 to 2022. Prior to Reinstein, Zaffer Syed held that position from 2017 to 2020. He's still an adviser for the company and recently announced his role as entrepreneur in residence at the Texas Medical Center.

Saranas is working on commercializing its Early Bird Bleed Monitoring System, touted as the first and only system FDA-approved bleeding detection system for procedures involving blood vessels. It is designed to detect bleeds early, enabling physicians to reduce medical risks and potentially avoid costly medical problems.

“Bleeding remains a common issue during and after endovascular procedures and can result in life-threatening complications,” says MacKinnon.

Since being founded in 2013, Saranas has treated over 1,200 patients with its device and has received $29.2 million in funding, according to Crunchbase. This includes a $12.8 million Series B round that Saranas got in 2021 from Chicago-based Baird Capital and Austin-based S3 Ventures.

The Early Bird device was developed at Houston’s Texas Heart Institute. The FDA approved the device in 2019.

Houston med device company secures first patient for clinical trial

health care tech

The first patient has been enrolled in a nationwide clinical trial that will evaluate the safety of Houston-based Saranas’ device for early detection of bleeding during minimally invasive heart procedures.

The initial patient was enrolled earlier this month at Morristown Medical Center in Morristown, New Jersey. The trial will eventually enroll up to 265 patients across the U.S.

Saranas’ Early Bird Bleed Monitoring System aids the detection of bleeding during high-risk percutaneous coronary intervention (PCI) procedures using mechanical circulatory support (MCS). In the clinical trial, the MCS will be the Impella heart pump.

PCI refers to minimally invasive procedures for opening clogged coronary arteries. MCS boosts heart function when the organ can’t perform at its best. The trial will test the ability of the Early Bird Bleed Monitoring System to detect serious or potentially fatal bleeding.

“As the field of minimally invasive, catheter-based procedures continues to advance, patient safety is paramount,” Dr. Babar Basir, director of acute mechanical circulatory support at Detroit’s Henry Ford Health System and co-principal investigator of SAFE-MCS, says in a news release. “This study will collect comprehensive procedural data in patients undergoing PCI with MCS.”

The data then will be reviewed to determine how real-time monitoring of bleeding can improve a patient’s health, Basir says.

Dr. Philippe Généreux, co-director of the Structural Heart Program at Morristown Medical Center, is the other co-principal investigator for the clinical trial.

“SAFE-MCS is the first prospective trial focused exclusively on the impact of integrating bleed monitoring in large-bore access for high-risk protected PCI patients,” says James Reinstein, president and CEO of Saranas, a medical device startup.

About one-fifth of patients will experience bleeding complications during “large bore” blood vessel procedures such as percutaneous MCS, transcatheter aortic valve replacement, and endovascular aneurysm repair. The estimated cost of one bleeding complication during these large-bore procedures is $18,000, adding up to an annual cost of $729 million for health care providers.

The Early Bird Bleed Monitoring System is the first and only device approved by the U.S. Food and Drug Administration (FDA) for real-time monitoring of bleeding problems during endovascular procedures for repair of blood vessels.

Saranas’ collaborators in the clinical trial are Proxima Clinical Research, a Houston-based contract research organization, and South Korea’s CardioVascular Research Foundation. The Early Bird study is expected to be completed by January 2023.

Since being founded in 2013, Saranas has collected $31.5 million in funding. This includes a $12.8 million Series B round that Saranas received this summer from Chicago-based Baird Capital and Austin-based S3 Ventures.

The Early Bird device was developed at Houston’s Texas Heart Institute. The FDA approved the device in 2019.

When James Reinstein took the helm of Houston-based Saranas in March 2020, he was tasked with taking the medical device company through its series B funding round and into larger clinical trials. Navigating these tasks during a global pandemic wasn't part of the plan.

"There was just so much uncertainty," Reinstein says on this week's episode of the Houston Innovators Podcast. "All of the funds didn't know which end was up, what hospitals would be doing, what procedures were going to begin again."

Saranas received FDA approval and began its clinical trials for its Early Bird Bleed Monitoring System in 2019. The device is designed to detect and track bleeding complications related to endovascular procedures. These medical procedures treat problems, such as aneurysms, that affect blood vessels. Around 20 percent of patients suffer a bleeding complication during endovascular procedures. Click here to read more.

Founded by Tatiana Fofanova, Dr. Desh Mohan, and Katelin Cherry, Koda Health uses AI to help patients create advance medical care directives and documents—such as a living will—through an easy to use web-based interface.

The app then autogenerates legal and medical documents, which patients can notarize or electronically witness the forms through the app or on their own.

According to Fofanova, who earned her PhD in in Molecular Medicine at Baylor College of Medicine in Houston and now acts as the company's CEO, what historically has been a time consuming and expensive process, through Koda Health, takes an average of 17 minutes and is completely free of charge to the end user.

"We hope to reduce any outstanding barriers to access that might exist," Fofanova says. "It is very frequently the oldest and the poorest that are the highest utilizers of health care that don't have access to these solutions." Click here to read more.

When James Reinstein took the helm of Houston-based Saranas in March 2020, he was tasked with taking the medical device company through its series B funding round and into larger clinical trials. Navigating these tasks during a global pandemic wasn't part of the plan.

"There was just so much uncertainty," Reinstein says on this week's episode of the Houston Innovators Podcast. "All of the funds didn't know which end was up, what hospitals would be doing, what procedures were going to begin again."

Saranas received FDA approval and began its clinical trials for its Early Bird Bleed Monitoring System in 2019. The device is designed to detect and track bleeding complications related to endovascular procedures. These medical procedures treat problems, such as aneurysms, that affect blood vessels. Around 20 percent of patients suffer a bleeding complication during endovascular procedures.

Reinstein explains that the way health tech funding trended over the past 18 months greatly affected Saranas. The device fell outside the parameters of what investors were looking for during this pandemic time. However, Reinstein explains, the Early Bird worked and had FDA approval — that made all the difference.

"We are very confident that the product does work and it can have a significant impact for hospitals and patients," Reinstein says. "Eventually, the term sheets came in."

Saranas announced in July that it closed a $12.8 million series B investment led by Wisconsin-based Baird Capital, the venture capital and global private equity arm of Baird, a global company with a location in Houston. Austin-based S3 Ventures also supported the round.

The funds will propel Saranas into its next phase, which includes growing its team, larger trials, and a next-generation product.

Reinstein has had decades in health care innovation all over the world, with a large chunk of his career at Boston Scientific. He's seen Houston's innovation ecosystem evolve.

"I do think that there's a great potential for Houston to really develop the industry," Reinstein says. "There's just two areas that need to get fortified. One is the funding and getting the funds directed to Houston companies — with the idea that the company stays in Houston. ... The other side of the coin is really finding the talent to come in and run the companies, take on leadership positions."

Reinstein shares more details on what's next for Saranas, as well as his advice for med tech entrepreneurs and observations on Houston's innovation ecosystem on the show. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Axiom Space launches Japanese subsidiary, names leadership

Axiom Space is setting up a Japanese subsidiary to tap into billions of dollars worth of business opportunities in the vast Asia-Pacific region. The company’s new office in Japan will open July 1.

“For the Asia-Pacific region, an Axiom Space presence in Japan means a long-term, direct path to low-Earth orbit for research, for industry, for astronauts, and a partner committed to building that future together with Japan,” Jonathan Cirtain, president and CEO of Axiom Space, said in a news release.

Asia-Pacific spaceflight leaders include Japan, China, India and South Korea.

Until committing to the Asia-Pacific subsidiary, Axiom focused primarily on the U.S. market for space exploration equipment, technology and services. Axiom is building the successor to the International Space Station (ISS), and it provides human spaceflight services and develops next-generation spacesuits.

Fortune Business Insights estimates the Asia-Pacific market for space technology was valued at $155.3 billion in 2025.

“The region is rapidly expanding due to rapidly expanding government space programs, increasing private sector participation, and rising demand for satellite services across densely populated regions,” says Fortune Business Insights, a market research firm.

The region’s combination of strategic investments, market demand and emerging entrepreneurial systems positions Asia-Pacific “for the fastest growth in the global market,” Fortune Business Insights says.

The market research firm pegs the U.S. market for space technology at $251.8 billion in 2025, making it the world’s largest player in that sector.

Veteran Japanese astronaut Koichi Wakata will lead Axiom Space Japan as chief technology officer in the Asia-Pacific region. The Japanese subsidiary will work with government agencies, research institutions, and industrial partners in Japan to expand hardware development and manufacturing, microgravity research and orbital computing.

Wakata was the Japanese space agency’s first program manager for ISS and the station’s first Japanese commander. He also contributed to the construction of ISS, including the Japanese experiment module Kibo. Wakata retired from the Japanese agency, JAXA, in March 2024.

“Japan intends to remain a leading nation in human space exploration post-ISS, and Japanese industry and academia are ready to play a central role in the commercial era,” Axiom Space said in the release. “Axiom Space Japan is how the company will meet that ambition with a long-term, on-the-ground presence.”

Houston investment firm closes $105M energy venture fund

seeing green

Houston-based investment firm Veriten has announced the initial close of its second flagship energy venture fund with more than $105 million in capital commitments.

Fund II will build on Veriten’s initial fund and aim to support “scalable technology solutions for energy, power and industrial applications,” according to a company news release.

"Our differentiated network, research-driven process, and first principles approach to investing are having an impact across multiple verticals including traditional energy, electrification, and industrial technology. Fund II builds on that platform,” John Sommers, partner, investments at Veriten, added in the release. “In this environment, the differentiator isn't capital – it's all about connectivity, deep sector expertise, and an economically-driven approach. As new technologies and approaches develop at breakneck speed, the need for more reliable, affordable energy and power continues to grow dramatically. The current backdrop accentuates the need for Veriten's solution."

Veriten is supported by over 50 strategic partnerships in the energy, power, industrial and technology sectors, including major players like Halliburton and Phillips 66.

"Veriten continues to build a differentiated platform at the intersection of energy, technology and industry expertise," Jeff Miller, chairman and CEO of Halliburton, said in the release. "We were early believers in the team and their ability to identify practical solutions to real challenges across the energy value chain. As all industries increasingly adopt digital tools, automation and AI-enabled technologies to improve performance and execution, we are proud to partner with Veriten again to help accelerate high-impact solutions across the broader energy landscape."

Veriten closed its debut fund, NexTen LP, of $85 million in committed capital in October 2023. It was launched in January 2022 by Maynard Holt, co-founder and former CEO of the energy investment bank Tudor, Pickering, Holt & Co.

It has invested in Houston-based AI-powered electricity analytics provider Amperon and led a $12 million Seed 2 funding round for Houston-based Helix Technologies to scale manufacturing of its energy-efficient commercial HVAC add-on earlier this year. In the past year it has contributed to funding rounds for San Francisco-based Armada and Calgary-based Veerum.

Veriten also named Nick Morriss as its new managing director earlier this month. Morriss most recently served as vice president of business development at next-generation nuclear technology company Natura Resources and spent nearly 20 years at NOV Inc.

Here's how Houston ranks among the best U.S. cities to start a career

New Horizons

College graduates staying in Houston are in the right place to be, according to a new WalletHub study. Houston has emerged on a new list of the 100 best places in America for starting a career.

Houston ranked 51st out of 182 U.S. cities based on its quality of life and vast opportunities for new college graduates transitioning into the workforce. The study compared each city based on 25 relevant metrics, like the availability of entry-level jobs, each city's annual job growth rate, workforce diversity, median annual income, housing affordability, and others.

Atlanta, Orlando, and Austin respectively comprised the top three best places to start a career.

Houston ranked 48th overall for its quality of life, and appeared No. 51 for its professional opportunities for new college graduates. Whether its starting a new business or entering a high-earning job field, Houston has many more opportunities than the vast majority of other cities on the list.

"The best cities for starting a career not only have a lot of job opportunities but also provide substantial income growth potential and satisfying work conditions," said WalletHub analyst Chip Lupo. "It’s also important to consider factors such as how fun a city is to live in or how good of a place it is for raising a family, to ensure life satisfaction outside of your career."

Other Texas hotspots for early career professionals
Austin boasts the best quality of life out of all 182 cities in the report, and the 10th best professional opportunities. The state capital also outperformed all other U.S. cities with the highest monthly average starting salaries for early career workers after being adjusted for the city's cost of living. Austin also offers the 15th highest number of entry level jobs per capita, the report said.
