We are pleased to announce that we’ve awarded $200,000 in non-dilutive Growth Grants to two St. Louis-based portfolio companies: Aegis Digital Health and Buck Surgical, each receiving $100,000 to advance to their next stage of growth.

“We’re thrilled to support Aegis and Buck Surgical through Growth Grants,” said Gabe Angieri, Executive Director. “These startups reflect the innovation, grit, and determination that define St. Louis’ startup ecosystem. We’re proud to help accelerate their path from breakthrough to impact.”

Launched in 2021, the Growth Grants program is designed to help existing Arch Grants portfolio companies scale operations, secure follow-on capital, and deepen their regional roots. Funds are awarded on a competitive basis and must be matched by additional external growth capital. Companies must maintain their headquarters in the St. Louis region for at least two years. An expert panel of volunteer judges comprised of investors, founders, and industry leaders selects awardees using a defined rubric.

“This award will help us reach a tipping point for our business,” said Stephen Von Rump, Co-Founder and CEO of Aegis Digital Health. “We have experienced dramatic revenue growth over the past six months but now we need to scale our operations to grow even faster. We’re deeply proud of how far we’ve come and grateful for Arch Grants’ support along the way. We are thrilled to continue growing as part of the St. Louis community.”

Dr. Donald Buck, Founder and President of Buck Surgical, sees this as a pivotal moment. “This is a true full-circle moment for Buck Surgical. Our Arch Grant award in 2021 was crucial in providing the springboard for our journey – the financial support, networking and entrepreneurial education, and the validation which allowed us to raise additional funding and develop our first device. Now, four years later, the Growth Grant will support our efforts to take our big, bold idea to commercialization where we can begin to save lives and limbs.”
