Boom Supersonic Secures $300M Series B to Power AI Data Centers and Supersonic Flight

Boom Supersonic, a Colorado-based aerospace startup, has closed a $300 million Series B round that will fuel both its ultrafast aviation ambitions and a new pivot into power generation for AI infrastructure. Darsana Capital Partners led the funding and came in significantly above initial targets – Boom had aimed for $150M but expanded the round due to strong investor demand. The raise values Boom at about $1.5 billion post-money and brings its total funding to over $700 million since its 2016 founding.
Best known for developing the Overture supersonic airliner, Boom recently unveiled a 42-megawatt gas turbine called “Superpower”, designed to supply on-site energy for AI data centers facing massive power needs. The Series B was announced alongside the Superpower launch, highlighting Boom’s strategy to generate near-term revenue from energy tech while continuing the long road of aircraft development. Investors responded enthusiastically: in addition to leading Darsana, the syndicate includes Altimeter Capital, ARK Invest (Cathie Wood’s fund), Bessemer Venture Partners, Robinhood Ventures, and startup accelerator Y Combinator. Their participation reflects confidence in Boom’s dual business model at the intersection of aerospace and the AI boom.
The fresh capital will be used to advance the development of Boom’s Symphony engine and scale up production of Superpower turbines, as well as to keep the Overture airliner program on track. Boom has already secured a $1.25 billion order backlog for the Superpower turbines (with Crusoe Energy Systems ordering 29 units to power data centers). Meanwhile, its Overture jet has 130 aircraft preorders from airlines including United and Japan Airlines, with a 2029 entry into service target. The funding will help Boom expand manufacturing capabilities, conduct engine testing (Symphony prototypes are expected to begin testing in 2026), and navigate the certification process for Overture. By blending an immediate opportunity in energy with its long-term supersonic aviation vision, Boom Supersonic aims to create a self-sustaining financial loop: using turbine sales to subsidize and de-risk the costly development of its airliner. This innovative approach, coupled with a vote of confidence from top investors, could enable Boom to overcome the traditional capital constraints of the aerospace industry.

QuEra Computing Lands $230M Series B to Scale Neutral-Atom Quantum Computers

QuEra Computing, a Boston-based quantum computing startup, has raised $230 million in Series B funding to accelerate the development of its neutral-atom quantum computers. The round was co-led by Google’s Quantum AI unit and SoftBank’s Vision Fund 2, bringing QuEra’s post-money valuation into unicorn territory (though undisclosed) and pushing its total funding to approximately $247 million. Also participating were strategic investors like NVentures (NVIDIA’s venture arm) and Valor Equity Partners, along with existing backers including QVT Family Office and Safar Partners. The syndicate’s composition – blending deep-tech VCs, corporate giants, and prior supporters – underscores confidence in QuEra’s technology and its progress to date.
Founded in 2018 by a team of Harvard and MIT scientists, QuEra is a pioneer in neutral-atom quantum computing, an approach that uses arrays of laser-trapped atoms as quantum bits (qubits). This design promises greater scalability: QuEra’s systems have already demonstrated 256-qubit processors (one of the largest of its kind), and the company is targeting thousand-qubit scale with error-corrected, programmable quantum machines. The new funding will be used to expand QuEra’s R&D and manufacturing capabilities, including expanding its Boston facilities and hiring top quantum engineers, as well as to accelerate the productization of its hardware and software stack. A portion of the raise includes a milestone-based tranche (~$60M) that provides QuEra with flexibility to manage capital as it meets technical benchmarks.
Crucially, QuEra has attracted strategic collaboration from industry leaders: Google’s investment hints at potential cross-pollination (even as Google pursues its own superconducting qubits, it sees promise in QuEra’s neutral-atom approach), and NVIDIA’s involvement via NVentures aligns with efforts to integrate quantum co-processors with classical high-performance computing (QuEra’s machines are already being linked with NVIDIA’s GPUs for hybrid quantum-classical simulations). With this Series B war chest, QuEra aims to deliver larger-scale systems capable of tackling problems intractable for classical computers – from complex material simulations to optimization challenges. The strong backing from both tech titans and veteran investors positions QuEra as one of the best-funded independent quantum startups, second only to a few industry leaders, and signals an accelerating race to achieve practical quantum advantage in computing.

Mirelo Scores $41M in Seed Funding Round to Give AI-Generated Videos a Voice

Berlin-based startup Mirelo has emerged from stealth with a $41 million seed funding round co-led by Index Ventures and Andreessen Horowitz (a16z), marking one of Europe’s largest seed rounds in the generative AI sector. At just two years old, Mirelo is building artificial intelligence that automatically adds realistic soundtracks and sound effects to AI-generated videos – essentially giving “silent” AI videos the audio they need to feel complete. The substantial seed funding (bringing Mirelo’s total raise to $44 million, including an earlier pre-seed) will enable the company to scale its team and technology in a nascent field at the intersection of AI and creative media.
Mirelo’s core product, Mirelo SFX, analyzes a video’s visuals and generates perfectly timed sound effects and ambient audio that match on-screen actions. For example, a generative AI video of a beach scene could be automatically outfitted with crashing wave sounds, seagull calls, and wind – all without a human sound designer. This technology addresses a growing demand: AI tools can now create images and videos in seconds, but they often lack audio, which is critical for immersion. By focusing on sound, Mirelo aims to become the go-to solution for creators and companies that need to add high-quality audio to their AI-generated visuals quickly. It’s a differentiation that attracted major VC interest, especially as big players from Sony to Tencent have begun experimenting with AI-driven sound for media. Despite competition, Mirelo’s narrow focus and early traction gave investors confidence, as evidenced by a seed round size usually reserved for more mature startups.
The company was co-founded by CJ Simon-Gabriel and Florian Wenzel, both of whom are AI researchers and musicians. Under their leadership, Mirelo will use the seed capital to recruit top talent in machine learning and audio engineering, likely doubling or tripling its 10-person team in the coming months. Funds will also support continued R&D to improve the fidelity of its sound-generation models and the expansion of Mirelo Studio, its creator-focused platform that could eventually allow users to generate custom soundtracks or even original music for their videos. Investors are optimistic that, as generative video content explodes, Mirelo’s technology will be in high demand to add dimension (sound) to those creations. By solving a “silent problem” in AI media, Mirelo is positioned at the forefront of a new niche – one where this big seed round gives it a considerable head start.

India’s Tagbin Raises $10M in Funding to Scale Experiential Tech and AI Platforms
Gurugram-based Tagbin has raised $10 million in fresh funding to expand its experiential technology business and its AI-driven government platforms. The investment was led by the SageOne Flagship Growth Fund, with participation from prominent Indian angel investors, including Ramesh Damani, Jyotivardhan Sonthalia, and others. This marks the first significant institutional funding for Tagbin, which was founded in 2013 by IIT alumni and has grown to date through bootstrapping and project revenues. The new capital will support Tagbin’s ambitious plans, including scaling its software products and potentially preparing for an IPO by 2027.
Tagbin made its name by designing large-format digital experiences – think interactive museums, immersive exhibitions, and innovation centers. Notably, the company has built high-profile museum installations and experience zones across India, blending physical and digital elements to engage visitors. In recent years, Tagbin has also leveraged this expertise to develop AI-based platforms for government agencies. For instance, it worked with India’s policy think tank, NITI Aayog, to create an AI-powered decision-support system that unifies and analyzes data across ministries, helping policymakers gain insights from previously siloed information. Tagbin is even piloting predictive policing analytics with some state police departments, using AI to identify crime patterns. These enterprise software offerings (marketed under products such as “Workly”) complement its one-off experience projects and generate recurring revenue through SaaS licenses and maintenance contracts.
With the $10M infusion, Tagbin plans to scale its software engineering and product development teams to serve more government and enterprise clients. A portion of the funds will bolster working capital as the company takes on large government tech projects, which often require upfront deployment of resources (and performance guarantees that tie up capital for years). Tagbin’s CEO, Saurav Bhaik, noted that the company surpassed ₹100 crore (approximately $12 million) in revenue last year and is targeting ₹200 crore this year, indicating robust growth. By strengthening its AI platform offerings and expanding into new sectors (potentially smart cities and education tech), Tagbin aims to transform from a project-based agency into a scalable product company. The backing from SageOne and reputed investors not only provides capital but also credibility as Tagbin sets its sights on a potential public listing. In a region where tech startups often focus on consumer apps, Tagbin stands out by straddling creative tech and enterprise AI, and this funding will help it accelerate at that unique crossroads.
