Houston-based medical device company BiVACOR has brought aboard a new CEO.

Jim Dillon, a longtime executive in the medical device sector, has been hired to lead BiVACOR and join its board of directors. Dillon succeeds former heart surgeon Dr. Thomas Vassiliades, whose appointment as CEO was announced in January 2022.

“Jim’s leadership style, combined with his experience in building high-performance teams as well as expertise in the heart failure field, makes him the ideal person to lead BiVACOR,” Raymond Cohen, chairman of BiVACOR, says in a news release.

Cohen was named chairman of BiVACOR in December 2023.

Most recently, Dillon was CEO of Massachusetts-based BioVentrix, a medical device company that focuses on minimally invasive procedures aimed at preventing heart failure. He previously held sales and marketing positions at medical device companies Abiomed, TherOx, and InfraReDx.

In November, the U.S. Food and Drug Administration (USDA) paved the way for BiVACOR to conduct a first-in-human clinical feasibility study of its Total Artificial Heart product. The study, initially featuring three patients at Houston’s Texas Heart Institute, is set to start during the first half of 2024. It will evaluate the device’s use as a substitute for a heart transplant.

The device “is unique in its complexity and importance as an advanced treatment option for end-stage biventricular heart failure patients,” Dillon says, and promises “to truly revolutionize the field.”

About 100,000 patients suffering from severe heart failure could benefit from BiVACOR’s artificial heart, the company says. For these patients, drug therapy is limited and the health prognosis is bleak, given the scarcity of donor hearts around the world.

Founded in 2008, BiVACOR maintains its headquarters in Houston, along with offices in Huntington Beach, California, and Brisbane, Australia.

To date, BiVACOR has raised nearly $37.8 million, according to CB Insights. The company’s investors include Boston-based Cormorant Asset Management, Australia-based OneVentures, the Australia Department of Health, and the National Institutes of Health (NIH).

Houston startup rolls out B2B program for onboarding new hires

job training

After seeing success with her internship training and matchmaking platform, Allie Danziger, founder and CEO of Ampersand Professionals, has expanded the concept to include a new hire training service that allows employers to better optimize the onboarding process and have a well-trained new staff member from day one.

In just over a year, Ampersand has worked with over 7,000 professionals through its original concept of upskilling and matching young professionals to internship programs. A few months ago, Danziger and her team expanded to include career development training for students first entering the workforce with the City of Houston's Hire Houston Youth program. Danziger says it was developing out the platform for this program that proved there was a need for this type of training.

"While we have focused on matching professionals with businesses for paid internships, we recognized a further gap with employers that have their own recruiting/talent acquisition teams, or just their own preferred way of bringing on entry-level talent, and didn’t have a need for our matching platform," Danziger tells InnovationMap. "But, they recognized the benefit of our proven training platform that pre-vets and de-risks their hires, and still wanted access to the training for their own hires."

The new program has evolved from training interns to new hires, so parts of the program that focuses on interviewing or applying for a job have been removed. Instead, the 8.5 hours of training focuses on networking, best practices for working with a manager and team, performance reviews, common software training, and more.

Danziger says usually new hires need the most experienced mentor or manager, but they don't usually get that support — especially when it comes to businesses that don't have their own built-out mentorship or training program.

"Ampersand’s new training product fills that gap — it gives employers of any size any easy solution to provide basic job readiness training to employees, access to our team of dedicated coaches, and a detailed report at the end of their training summarizing how their new hire did in the training and any trends recognized and tips for managing this employee based on what the platform uncovered," she says. "Businesses can also sign up for additional coaching sessions and customize training materials, as an add-on if interested."

The program costs the employer $100 per new employee, and checkout online takes less than a minute. Through both this program and the original internship program, Ampersand is constantly evolving its training content.

"These professionals are going through the same training experience that we have proven out over the last year, and we are constantly adding to based on data we see in the user experience," Danziger says.

Danziger recently joined the Houston Innovators Podcast discuss some of the benchmarks she's met with Ampersand, as well as the importance of investing in Gen Z hires. Listen to that episode below.
