Earlier in his career, he held senior leadership positions with Medrad Interventional, AGA Medical, and Cordis. Darby is a former Captain in the United States Marine Corps and earned a Bachelor of Arts from the University of Michigan.

“CIRCA has assembled a unique portfolio addressing several of the most important access challenges in electrophysiology and structural heart intervention,” said Darby. “The Company’s physician-driven innovation, combined with multiple differentiated technologies now in market, creates an exciting platform for future growth. Our opportunity is to transform these innovations into solutions that physicians rely on every day while continuing to enhance our portfolio through disciplined execution, close collaboration with clinical leaders, and a relentless focus on improving patient care. I am honored to join the talented CIRCA team and look forward to leading the Company’s next chapter.”

“Jack is the right leader to guide CIRCA through its next stage of growth,” said Doug Wall, Chairman of the Board. “His combination of commercial leadership, operational expertise, and deep cardiovascular experience makes him uniquely qualified to accelerate physician adoption of our technologies, expand our market presence, and build upon the strong foundation the Company has established. As CIRCA expands its cardiovascular access portfolio, Jack’s experience scaling organizations and creating shareholder value will be instrumental to our continued success.”

“Jack brings the strategic vision and commercial expertise needed to capitalize on the significant opportunities ahead,” said Vafa Jamali, independent member of the Board of Directors. “We are confident he will build on CIRCA’s momentum and further strengthen the Company’s position as an innovator in cardiovascular intervention.”

Geist will transition to Chief Operating Officer, where he will oversee key operational initiatives and support the continued execution of CIRCA’s growth strategy while remaining a member of the Company’s Board of Directors. During his tenure as Chief Executive Officer, Geist helped establish CIRCA as a recognized innovator in esophageal temperature monitoring while guiding the successful development and FDA clearance of both the CrossWise™ RF Transseptal Access System and the PeriCross™ Epicardial Access Kit.

“It has been a privilege to lead CIRCA through this important period of innovation and product development,” said Geist. “The Company has never been better positioned for the future, and I am excited to work alongside Jack as we accelerate commercialization, continue advancing our pipeline, and build upon the strong foundation our team has created.”

Northern Hemisphere Heat Drives Demand for Cooling and Sun-Protection Products on Yiwugo

Published

on

By

YIWU, China, July 24, 2026 /PRNewswire/ — Yiwugo.com, the official website of the Yiwu Commodity Market, is the largest commodity wholesale market in the world. The final whistle may have blown on the World Cup, but the intense heat gripping the Northern Hemisphere shows no sign of letting up. Europe has experienced unusually hot weather this year, sparking not only a surge in demand for air conditioners but also a boom in portable handheld fans. Merchants on Yiwugo say that in previous years, European customers would begin placing orders in March or April and take their time completing their annual procurement. This year, however, the purchasing season has stretched well into summer, with a flood of new buyers coming in, most of them looking for small handheld fans. With customers eager to capitalize on the peak summer season, delivery timelines have also become significantly tighter. Whereas orders in previous years could generally be fulfilled within a month, merchants are now frequently being asked to deliver within about a week, leaving manufacturers scrambling to keep pace with demand.

Lingpan Official Flagship Store has specialized in the production and sales of small fans, insulated cups, and related products for 15 years. This summer, demand from European customers for high-speed small fans has risen sharply, accompanied by urgent delivery requirements. Many customers began requesting shipment just one week after placing their orders, hoping the products would arrive in time for the World Cup and the ongoing heatwave across Europe. One long-standing European customer purchased only five models of small fans from Lingpan last year. Anticipating stronger demand ahead of this summer, the customer expanded the order to 10 models. The first shipment sold out soon after arriving at port, prompting several subsequent repeat orders. European buyers have shown particular interest in high-speed cooling fans and placed great requirements on product quality. So far this year, Lingpan’s fan sales have more than doubled compared with the same period last year, with total purchases reaching approximately RMB 1 million.

Beyond Europe, the owner of Lingpan, Ling Pan pointed out that the Indian market has also undergone significant changes over the past two years. Indian customers are showing great interest in panda-shaped fans, drinking cups, and related products. Procurement volumes among many Indian buyers have increased substantially, with average annual purchases now reaching several hundred thousand yuan.

Unlike European countries grappling with sudden heat waves, Asian markets such as Japan and South Korea, where summers are consistently hot and air conditioners and fans are already everyday essentials, have shown much stronger demand for sun-protection products. From April 1, 2026 to date, sales of sun-protection masks on Yiwugo have increased by 31.6% YoY, while sales of sun-protection face shields surged by 72.42% and sun hats rose by 8.1%.

Chen Jia, a Yiwugo merchant, has engaged in the production and sales of sun-protection masks and sun-protection face shields for eight years. Chen operates the Xiao Zhen and Xiao Mian Sun-Protection Products Workshop in District 4 of the Yiwu International Trade Market. In recent years, the company has customized cooling nylon fabrics for customers in Japan and South Korea. Sun-protection masks and sun-protection face shields made from this material not only offer UPF 50+ protection, but also maintain a more structured shape and are less susceptible to snagging or deformation. Their protective performance remains effective after routine washing, and the products can last for more than five years under normal use.

In 2024, a TV shopping operator from South Korea contacted Xiao Zheng and Xiao Mian through Yiwugo and began placing orders after inspecting the products in person. Over the following two years, the company continued to improve the fitness and design of its sun-protection products. It introduced sun-protection face shields with breathable mesh panels and incorporated soft supports around the nose area to prevent the masks from rubbing against lipstick. These product upgrades have steadily driven up customer ratings on the client’s store. Annual procurement, initially valued at around RMB 300,000, has risen year by year, and the company has since developed into a recognized brand in the local market.

Persistent heat across the Northern Hemisphere has been creating new forms of cross-border consumer demand while enabling Yiwugo merchants to keenly capture shifts in overseas markets. From the strong sales of small portable fans in Europe to the rising demand for functional sun-protection products in Japan and South Korea, the diversity of orders reflects both consumers’ need for relief from extreme heat and the ability of Yiwu manufacturers to strengthen their presence in global markets through product innovation and rapid fulfillment. Faced with a rapidly changing international market, many merchants are continuing to refine product designs, upgrade fabric techniques, and enhance supply efficiency. By leveraging Yiwugo to broaden their export channels, they are keeping pace with overseas consumption trends and capitalizing on the expanding market for cooling and sun-protection products, turning the summer heat into new momentum for cross-border trade.

Snorkel AI Highlights First Wave of Open Benchmarks Grants Projects

Published

on

By

SAN FRANCISCO, July 24, 2026 /PRNewswire/ — Snorkel AI today highlighted the first group of projects supported through Open Benchmarks Grants, a $3 million commitment to support open-source datasets, benchmarks, and evaluation research.

Launched in February 2026, Open Benchmarks Grants has received hundreds of applications from researchers, labs, and engineers working to address a growing challenge: AI systems are advancing faster than the field’s ability to rigorously measure their performance on realistic, consequential work.

“From complex environments and huge autonomy horizons to rich, sophisticated outputs, these projects tackle some of the field’s hardest evaluation challenges,” said Fred Sala, a member of the Open Benchmarks Grants steering committee and assistant professor at the University of Wisconsin–Madison. “I’m excited to see the broader research community use, validate, and build on them.”

Open Benchmarks Grants provides selected teams with funding, expert data development support, research and engineering collaboration, and platform resources. Supported projects include:

Frontier-Bench (formerly Terminal-Bench 3.0), developed with Laude Institute and the Harbor community, is a harder, more domain-diverse successor to Terminal-Bench 2.1 — built in the open, task by task, under continuous adversarial review.Agents’ Last Exam, developed with UC Berkeley RDI and the RDI Foundation, evaluates agents on long-horizon, economically valuable professional workflows. It spans 55 sub-industries and includes more than 1,500 tasks toward a 5,000-task target, sourced and validated by more than 300 industry experts.OSWorld 2.0, developed with XLANG Lab, evaluates computer-use agents on 108 long-horizon workflows across 31 self-hosted web environments and professional desktop applications.Continual Learning Bench, developed with UC Berkeley SkyLab and the University of Wisconsin–Madison, measures whether agents genuinely improve across sequential, stateful tasks.SlopCode Bench, developed with the University of Wisconsin–Madison, measures how code quality degrades as coding agents repeatedly modify and extend their own solutions.Terminal-Bench 2.1, developed with Stanford University, Laude Institute and the Harbor community, evaluates agents on challenging work in terminal environments. The release corrected 28 tasks and introduced continuous validation.

With support from Open Benchmarks Grants, Terminal-Bench Science is also now in development, extending the Terminal-Bench framework to computational research workflows across the life, physical, earth, and mathematical sciences.

Beyond the grants program, Snorkel led the development of Senior SWE-Bench with the research teams at Princeton University and the University of Wisconsin–Madison. The benchmark evaluates coding agents on senior-level engineering work, including implementing features from realistic instructions, investigating bugs that require runtime analysis, and producing code that follows existing codebase conventions.

Open Benchmarks Grants was established with support from Hugging Face, Prime Intellect, Together AI, Factory, Harbor, and PyTorch. Applications remain open and are reviewed on a rolling basis.

Payzli Vaults to No. 3 on Tampa Bay’s Fast 50, Up From No. 22 in One Year

Published

on

By

Payments technology company, Payzli earns a second consecutive Fast 50 ranking, crediting the climb to accelerating partner and merchant growth on its proprietary technology stack.

TAMPA, Fla., July 24, 2026 /PRNewswire/ — Payzli, the partner-first payments technology company, has been named the No. 3 fastest-growing company in the region on the Tampa Bay Business Journal’s 2026 Fast 50 – a 19-spot climb from its No. 22 debut last year, and the company’s second consecutive year on the list.

The ranking was announced July 23 at the Tampa Bay Business Journal’s Fast 50 event in Tampa, where Co-Founder and Chief Revenue Officer Naim Hamdar accepted the award alongside members of the Payzli team.

Payzli attributed its growth to a compounding effect: a national network of ISOs, agents and ISVs bringing merchants onto a technology platform Payzli built and operated in-house. 

That platform rests on three proprietary pillars:

Payzli Connect: the company’s payment CRM and merchant-and-partner dashboard, giving agents and ISOs daily residuals visibility and giving merchants a single place to run their account.Payzli POS: AI-powered point-of-sale and business software purpose-built for service businesses, including salons, med spas, wellness studios, and independent operators.Payzli Transact: an online payment gateway built on Visa Platform Connect through Payzli’s partnership with Visa Acceptance Solutions.

The Visa Acceptance Solutions partnership is central to how Payzli frames its credibility: rather than assembling a growth story on top of borrowed infrastructure, the company processes on rails backed by one of the most established networks in the industry alongside Fiserv and TSYS – a point that matters to the partners and merchants deciding where to place their volume.

“A second year on this list, and a jump to No. 3, isn’t about one good quarter. It’s about a network deciding to build with us and stay,” said Naim Hamdar, Co-Founder and Chief Revenue Officer of Payzli. “Every rank on this list represents partners we’ve earned and merchants who trust us to run their payments. We built the technology in-house so we could keep the promises the industry usually breaks: nothing hidden, a real person in reach, and daily residual visibility our agents can actually count on. That’s what this ranking measures and it’s why we’re doing it all, for the joy of business.”

“They say nothing in Tampa moves fast except the afternoon thunderstorms, so making the Fast 50 two years running feels pretty good,” said Kapil Pershad, Co-Founder and Chief Technology Officer of Payzli. “In all seriousness, this is a credit to our team and the businesses that trust us to power their growth.”

The Fast 50, produced by the Tampa Bay Business Journal, recognizes the fastest-growing private companies in the Tampa Bay region. Payzli’s return to the list and its move into the top three reflects a merchant-first product suite and a rapidly expanding national partner network across the payments and embedded-finance landscape.
