Liz Dennett's Endolith Wins VivaTech Female Founder Award in Paris

Liz Dennett, founder and chief executive of Endolith, has turned the 2026 VivaTech Female Founder Award into a timely business story about women building companies in hard science, climate infrastructure and deep technology.

VivaTech's June 20 recap of its 10th anniversary edition named Dennett as the Female Founder Award winner after the Paris event drew more than 200,000 visitors from 165 nationalities and more than 15,000 startups. The award was one of the startup prizes highlighted by VivaTech alongside awards for Tech for Change, AfricaTech, Next Startupper and Innovation of the Year. For SheMeansNews readers, the signal is clear: the women-founder conversation is moving beyond consumer apps and into industrial systems where capital, technical credibility and commercial patience matter.

Endolith is a Denver-based biotechnology startup working on microbial approaches to copper recovery. Founders Factory's profile of Dennett describes the company as a platform that pairs engineered microbes with AI and real-time data so extraction can adapt to tough ores. The company story matters because copper is central to electrification, renewable energy, grids and electric vehicles, while traditional mining faces pressure over cost, environmental impact and declining ore quality. A woman founder winning a major startup award for that kind of company is different from another panel about representation. It puts a female-led team inside one of the harder supply-chain problems attached to the energy transition.

The award also reflects the shape of this year's Female Founder Award field. VivaTech said 444 female founders from 85 countries applied, with 72.9 percent of the startups coming from outside France and 75 percent already raising funds. The five finalists were drawn from healthtech, deeptech, climate, biotech, materials and mobility, including Ark Climate, Endolith, ExoMatter, Robeaute and Revolty. That mix challenges the narrow assumption that women-founded startups are mainly concentrated in femtech or lifestyle categories. The finalists were building climate action software, biomining technology, AI materials platforms, brain microrobotics and electric vehicle charging networks.

Dennett's own founder path gives the award extra weight. Founders Factory says Endolith grew from a late-night conversation in Edinburgh about the resource bottlenecks that could shape humanity's future. Dennett had studied astrobiology, worked on microbes in research settings and later focused that background on copper. The company joined Founders Factory in 2024 with Rio Tinto backing and, according to the profile, had raised 5.5 million dollars while working across the United States, Australia and South America. TechCrunch previously reported on Endolith's seed funding and described a leadership team working to improve copper recovery with microbes.

The leadership point is practical. Deeptech founders often have to sell several ideas at once: the science, the market, the customer urgency, the regulatory pathway, the operating model and the reason a traditional industry should change. Women founders face that same burden while also dealing with investor pattern-matching that can underprice technical ambition when the founder does not look like the sector's usual operator. A public award will not solve that funding gap, but it can shift visibility toward founders whose companies are working on capital-intensive and infrastructure-linked problems.

For women in business, Dennett's win is useful because it offers a more demanding example of what founder coverage should include. The story is not only that a woman won a prize. It is that a woman is building in mining technology, a field where the customer base is conservative, the science is complex and the upside depends on industrial adoption rather than quick consumer growth. That kind of company needs patient capital, technical teams, pilot projects and credibility with large operators. It also gives younger scientists and operators a visible example of a founder path that starts in research and moves into commercial execution.

The next test will be whether the award leads to measurable business momentum. VivaTech says the award is designed to increase visibility, create investor connections and support access to funding. Endolith will still have to prove its technology in field validation and commercial deployment, and the mining industry will still have to decide how quickly it is willing to adopt biological intelligence as part of mineral recovery. But the Paris result gives Dennett and Endolith a stronger public platform at a moment when copper supply, clean-energy infrastructure and women-led deeptech all deserve closer business attention.
