A Houston-based blockchain company that focuses on providing companies with ethical and sustainable practices within the supply chain has closed a $3 million round with support from investors both locally and across the country.

Today, Topl announced the closing of its seed round, which was led by Houston-based Mercury Fund with support from Houston-based GOOSE Capital, Chicago-based Chingona Ventures, Dallas-based RevTech Ventures, and New York-based firms Beni Venture Capital, Blue Collective, and Social Impact Capital.

"We're grateful to have closed an oversubscribed venture round during a pandemic, especially given the unfortunate truth that many women-led startups are getting much less investment during this time," says Kim Raath, CEO of Topl, in a press release. "Bringing transparency to causes dedicated to environmental and social good has never been more important. We are building a modern blockchain for a world where purpose and profit go hand in hand."

According to the release, Topl will use the fresh funds to speed up the launch of the company's blockchain-as-a-service solution for early next year.

Earlier this month, Topl announced a partnership with Denver-based TrackX, a software-as-a-service asset management and supply chain solution provider, aimed at combining technology to create a verifiable tracking and tracing solution to equip company supply chains with sustainability, transparency, and efficiency. Ultimately, it's Topl's goal to allow its users the ability to stand out to customers as sustainable and responsible brands — something that's become increasingly more important to consumers.

"A company's social and environmental impact has become a necessary point of differentiation for brands, and Topl has the potential to be the leading player for brands who are serious about [Environmental, Social, and Corporate Governance]," says Blair Garrou, managing director of Mercury Fund.

To date, Topl has raised $4.4 million in funding. It's first seed round closed September 2019. For that round, Samantha Lewis, formerly director of GOOSE Capital, was instrumental, according to the release.

"Kim and the Topl team have created a custom-designed method to measure and verify your company's sustainability efforts. We're excited to be part of this intersection of cutting-edge technology and positive impact," Lewis, who's now on the board of the startup, says in the release.

Topl's technology has the ability to affect any industry, and the company has worked with tracing products from diamonds and chocolate to natural resources and even COVID-19 testing.

"Topl's track-and-trace solution appeals to so many core industries: from healthcare to agriculture to energy," says Manolo Sánchez, former chairman and CEO of BBVA Compass and also a member of Topl's board, in the release. "Anyone who needs to ensure transparency, efficiency and sustainability would benefit from their technology."

New 'living pharmacy' biotech company launches out of Rice venture studio

fighting cancer

Rice University’s biotech venture studio RBL LLC has launched a new “living pharmacy” company, Duracyte, designed to make cancer treatment easier on patients.

Backed by an up to $45 million Advanced Research Projects Agency for Health (ARPA-H) award, Duracyte aims to commercialize implantable biohybrid pharmacy devices that are designed to produce therapeutic proteins inside the human body around the clock, replacing the need for regular injections and infusions for some cancer patients.

The company’s main platform is its Hybrid Advanced Molecular Manufacturing Regulator (HAMMR), a rechargeable, implantable device that can sense biological signals, monitor tumor environments and adjust therapeutic output in real time. HAMMR has wireless communication capabilities, which allow patients and clinicians to remotely monitor results through an app every five minutes and make changes to treatment plans without a hosptial visit. Additionally, the device can generate its own oxygen supply, which is key for the therapeutic cells’ survival.

“Biologic medicines such as monoclonal antibodies, cytokines and metabolic regulators already account for a significant share of modern therapeutics, but the way we deliver them today often requires frequent injections or infusions that can be demanding for patients and lead to inconsistent drug levels,” Daniel Anderson, MIT professor and co-founder of Duracyte, said in a news release. “Our vision is to enable a continuous, stable therapy by producing these medicines directly inside the body, which could improve treatment consistency, reduce side effects and ultimately transform how biologic therapies are delivered across many diseases.”

Duracyte’s first clinical trial is slated to begin by the end of 2026 and will focus on recurrent ovarian cancer. The Phase I study will build upon existing work on encapsulated cytokine pharmacy technology, and the company hopes that within a few years this treatment can reach clinical application.

The development of Duracyte is supported by ARPA-H's Targeted Hybrid Oncotherapeutic Regulation (THOR) project, which supports a multidisciplinary research consortium co-led by Omid Veiseh, a professor of bioengineering at Rice. The consortium also includes others at Rice, The University of Texas MD Anderson Cancer Center, Stanford University, Carnegie Mellon University, Northwestern University and the University of Houston, plus industry collaborators like Chicago-based CellTrans.

“What we are building is the culmination of years of progress in cell engineering, biomaterials and implantable device technology,” Veiseh added in the release. “By combining these advances with real-time sensing and adaptive drug delivery, we are working with the support of RBL to create a true ‘living pharmacy’ that can deliver continuous, precisely controlled biologic therapies and fundamentally change how these treatments reach patients.”

RBL launched in 2024 and is based out of Houston’s Texas Medical Center Helix Park. Duracyte is the third company launched by RBL, including Sentinel BioTherapeutics, a clinical-stage immunotherapy company developing localized cytokine therapies for solid tumors, and SteerBio, a regenerative medicine company targeting lymphedema.

“Duracyte exemplifies the kind of breakthrough that Houston’s ecosystem is built to produce,” Paul Wotton, managing partner of RBL LLC and co-founder of Duracyte, added in the release. “With world-class clinical infrastructure, exceptional engineering talent and initiatives like the Texas Biotech Task Force driving alignment across industry, investment and talent, this region is uniquely positioned to move the most ambitious ideas in medicine from concept to patient, faster than anywhere else.”

Houston energy hub opens new fundraising cohort to fuel startups

Apply Now

EnergyTech Cypher has opened applications for its second Liftoff fundraising program.

Applications close May 20 for the 10-week virtual fundraising sprint. The program is geared toward energy and climatech founders preparing to raise their first institutional round. It will cover fundraising requisites, like pitch materials, term sheet negotiation and round closing, according to a release from EnergyTech Cypher.

The program kicks off June 1 and runs every Monday from 1-3 p.m. CST. It will conclude with an in-person capstone simulation in Houston on August 3, where founders will work to close a mock round.

Jason Ethier, EnergyTech Cypher founder and CEO, will lead the program with Payal Patel, an EnergyTech fellow and entrepreneur in residence.

The program is available through Cephyron, EnergyTech Cypher's new investor relationship management platform, built specifically for energy and climatech founders. Users must have a Cephyron Boost membership to participate in the Liftoff program.

The Cephyron IRM app recently went live and is available to founders at any point in their fundraising process, according to the news release. The platform aggregates investor data, tracks market signals and delivers curated weekly recommendations.

EnergyTech Cypher launched Liftoff last year. The inaugural cohort included 19 startups, including Houston-based AtmoSpark Technologies, The Woodlands-based Resollant and others. Each participant closed at least one fundraising deal, according to EnergyTech Cypher.

EnergyTech Cypher rebranded from EnergyTech Nexus earlier this year. It also launched its CoPilot accelerator in 2025. The inaugural group presented its first showcase during CERAWeek last month.

EnergyTech Cypher's annual Pilotathon Pilot Pitch and Showcase applications also opened this month. Find more information here.
