5 Interesting Startup Deals You May Have Missed: A Law Firm Operating System, Building Defense Tech Near The Battlefield, And Cell-Based Milk

This is a monthly column that runs down five interesting startup funding deals that may have flown under the radar. Check out our previous entry here . AI and software continue to draw the biggest share of startup investment, but most of the interesting companies that caught our eye in the past month were working on problems in the physical world, often far from the glow of a laptop screen. They include a defense-tech startup that aims to bring manufacturing closer to the frontlines, a company working to recycle valuable raw materials from defunct solar panels at industrial scale, and a startup that wants to produce cell-based milk for the dairy supply chain. Let’s take a look. $82M to build near the battlefield A decade ago, defense tech was considered a niche and sometimes controversial corner of venture capital, with few startup investors daring to place bets on companies working with the military. How times have changed. Already this year, $13.6 billion in venture investment has gone into companies in Crunchbase’s military, national security and law enforcement categories — more than 1.5x last year’s annual total. Firestorm Labs is one of the latest defense startups to get some of that funding, with an approach that aims to bring defense manufacturing closer to the battlefield. The San Diego-based startup last month announced an $82 million Series B led by Washington Harbour Partners . Firestorm builds expeditionary manufacturing systems and modular drones for military use. Its containerized “xCell” manufacturing platforms are designed to produce drones, replacement parts and other systems closer to the battlefield — a concept gaining traction as militaries rethink supply chains and logistics in contested regions such as the Indo-Pacific. Existing and new investors including, IQT , Lockheed Martin , Litquidity Ventures , Booz Allen Ventures and others also joined its latest funding round, which brings Firestorm’s total funding to nearly $150 million, per Crunchbase. “The ability to produce, adapt, and sustain systems at speed and scale will define outcomes in future conflict,” Mina Faltas , founder and chief investment officer at Washington Harbour Partners, said in a statement. “We’re excited to lead Firestorm’s Series B and back a company building a new model for manufacturing that replaces centralized supply chains with deployable, containerized units that can operate at the edge.” The raise lands amid a broader surge in investor appetite for military tech, not just from defense-industry investors but also some of Silicon Valley’s biggest names in venture. Sector heavyweight Anduril Industries recently raised another $5 billion at a staggering $61 billion valuation in an Andreessen Horowitz – and Thrive Capital -led round, underscoring just how mainstream venture-backed defense startups have become.

That growth, of course, has been driven by AI’s rapid automation of many aspects of the notoriously paperwork-heavy industry. Last month, Manifest OS , a startup that says it’s building the operating system and brand for AI-native law firms, has raised $60 million in Series A funding at a $750 million valuation from big-name investors. Menlo Ventures led the round and Kleiner Perkins , First Round Capital and Quiet Capital participated. Manifest OS says it takes a different tack than most legal tech startups. Rather than sell software to traditional law firms that operate under a billable hour model, the company only caters to AI-native firms that charge clients based on outcomes. “Companies want fee transparency, predictability, and speed,” David Schellhase , a Manifest investor and former general counsel for Salesforce , Groupon and Slack , said in a statement. “Lawyers want to focus on delivering results, not justifying billable hours. Manifest OS’s model and use of advanced technology align those interests in a way the traditional system simply doesn’t.” Along with AI software that helps attorneys with tasks like client communications, legal research, document drafting and billing, Manifest OS also offers a centralized back office to handle client intake, business development, paralegal work and other administrative tasks. That, according to the firm, frees attorneys up to focus on more complex legal work. One important caveat: All firms that use its platform operate under the Manifest Law name. According to the startup, that results in a consistent brand presence, pricing, response time and service quality to clients. Its first practice operating under that name is a business immigration law firm. The startup says it has already served 150-plus corporate clients, including large tech companies, since launching 18 months earlier. It has hired more than 100 attorneys to date, it said, less than 1% of those that applied.

By 2050, tens of millions of tons of solar panels are expected to become defunct, according to ROSI. The company’s technology recovers high-purity raw materials including silver, silicon, copper, aluminum and glass from those panels so that they can be recycled into new products. ROSI said the new funding will be used to build its first large-scale recycling plant in Spain. The site will be able to process 10,000 tonnes per year. The funding was led by EIT InnoEnergy , CMA CGM , European Innovation Council and Spanish family office G3T . Zurich-based corporate advisory firm Finadvice , which specializes in deep tech, acted as strategic financial advisor and investor. Other investors included unnamed Swiss and Polish family offices. “Our ambition is to build a European-scale industrial platform for circular management and the production of strategic raw materials, transforming end-of-life solar panels into a reliable source of high-purity materials for the European industries of tomorrow,” ROSI President and co-founder Yun Luo said in a statement. The investment comes as cleantech funding has seen tepid investor enthusiasm in recent years. Overall funding to startups in Crunchbase’s cleantech-, electric vehicle- and sustainability-related categories fell to a five-year low in 2025 . Still, some areas — including solar and recycling — have continued to see larger rounds.

Companies working on cell-based alternatives to traditional sources of protein such as meat and dairy products, in particular, have largely fallen out of favor with startup investors in recent years, Crunchbase data shows. That makes Montreal-based Opalia ’s recent $3.2 million CAD (roughly $$2.3 million) seed round all the more interesting. The company, previously named BetterMilk, says it produces “complete milk” — with proteins, fats and sugars — from mammary cells in a bioreactor, without employing any cows. Its recent round was led by Nadarra Ventures , with participation from Spring Impact Capital , UCeed , Anges Quebec and existing investors including Investissement Quebec , Cycle Momentum and BoxOne Ventures . Rather than make a direct-to-consumer play, as many food and beverage startups have done, Opalia is positioning it
