Valthos has raised US$30 million in seed funding, led by the OpenAI Startup Fund, Lux Capital and Founders Fund, to advance its mission of building next-generation biodefense systems.
The company’s work comes at a time when biotechnology is evolving at an unprecedented pace. Biotechnology is moving at record speed. These new tools can lead to life-changing medical discoveries, but they also bring the risk of dangerous biological agents being developed faster than ever.
“The issue at the core of biodefense is asymmetry”, said Kathleen McMahon, co-founder of Valthos. “It’s easier to make a pathogen than a cure. We’re building tools to help experts at the frontlines of biodefense move as fast as the threats they face”. The gap Valthos aims to close is between the rapid rise of biological threats and the slower pace of developing cures. Therefore, the company is developing AI systems that can rapidly analyze biological sequences and significantly shorten the time needed to design medical countermeasures.
“In this new world, the only way forward is to be faster. So we set out to build a new tech stack for biodefense”, said Tess van Stekelenburg, co-founder of Valthos. “This software infrastructure strengthens biodefense today and lays the groundwork for the adaptive, precision therapeutics of tomorrow”.
The company was founded by van Stekelenburg, a partner at Lux Capital and McMahon, the former head of Palantir’s Life Sciences division. Together, they’ve built a multidisciplinary team of experts from Palantir, DeepMind, Stanford’s Arc Institute and MIT’s Broad Institute, bringing together deep experience in software engineering, machine learning and biotechnology.
“Technology is moving fast. An industrial ecosystem of builders, companies and solutions further democratizes AI to provide broad resilience, and ensures the U.S. continues to lead as AI increasingly powers everything around us. As AI and biotech rapidly advance, biodefense is one of the new industry verticals that helps maximize the benefits and minimize the risks”, said Jason Kwon, OpenAI’s Chief Strategy Officer. “Valthos is pushing the frontier of protection and defense in one of the most strategic intersections of multiple world-changing technologies, and with the team to do it”.
Looking ahead, Valthos plans to expand its engineering team and scale its software infrastructure for both government and commercial partners — moving closer to its goal of enabling faster, smarter and more adaptive biodefense capabilities.

New funding and ad support aim to ease capital gaps for small wedding businesses

The Knot Worldwide, a global wedding technology platform and vendor marketplace, has launched a new grant initiative aimed at small businesses in the wedding industry.
The company, which operates brands such as The Knot and WeddingWire, connects couples with wedding professionals and provides tools to help vendors grow. It says the new WeddingPro Grant Program is designed to address a persistent challenge in the sector: access to capital.
Under the program, up to US$500,000 will be distributed to U.S.-based wedding professionals who run small businesses. The support will come in the form of financial grants, advertising credits on WeddingPro and mentorship. Selected businesses will also receive access to education resources and community support through the company’s network.
The move comes at a time when many wedding businesses remain small and resource-constrained. According to the company’s State of the Vendor Report, more than half of wedding businesses employ fewer than ten people. Three in four professionals surveyed said adaptability is critical to long-term success, while flexible funding remains a barrier. The grant program is positioned as a response to that funding gap.
“Our mission at The Knot Worldwide is to help the nearly 900,000 small businesses on our global platforms get discovered through our centralized vendor marketplace as well as give them the tools and resources to grow their business,” said Raina Moskowitz, Chief Executive Officer, The Knot Worldwide. “We consistently hear from our wedding professionals that access to capital is a barrier to getting started in the industry. With our new WeddingPro Grant Program, we will provide access to both capital and critical support services such as mentorship and education that will enable small business owners to further grow and scale.”
The application window opens on February 23 and closes on March 27. Winners are expected to be notified by May 2026, subject to eligibility verification and compliance with the official rules.
The program is open to U.S. wedding professionals who operate small businesses, have been in business for at least six months, can demonstrate an active revenue stream and earn at least 50% of their revenue from weddings. Applicants must submit a short form and a video outlining their business and how they would use the grant funds over the next 12 to 24 months. They can choose whether they prefer a monetary grant or free advertising support on WeddingPro.
To execute the program, The Knot Worldwide has partnered with the Global Entrepreneurship Network, which works with entrepreneurs worldwide. The company says the initiative builds on earlier efforts to support vendors on its platform, which includes about 200,000 wedding professionals in the United States. Its impact will depend on how effectively the support reaches the businesses that need it most. The real measure will be whether it helps them achieve steady, sustainable growth.
