  • VFlow Tech

    Participated · Equity · May 2025

    VFlowTech develops vanadium redox flow battery (VRFB) systems and hybrid batteries for long-duration energy storage and offers an AI-driven cloud energy management platform to manage, monitor and optimise distributed renewable assets. The platform also provides energy trading and ancillary services for the grid. Established in 2018 and based in New Delhi, the company has deployed its long-duration storage systems across more than 10 countries. VFlowTech raised $20.5M to support strategic expansion into India’s clean energy sector and to scale hiring across engineering, research and operations. The company plans to advance vanadium recycling and create innovations around electrolyte manufacturing in India to build local supply chain efficiencies. VFlowTech manufactures vanadium redox flow batteries branded as PowerCubes, featuring a power stack design that enables a more compact form factor, higher-than-industry round-trip efficiency, reduced parasitic losses and operation above 55°C. Different PowerCubes can be deployed from residential settings to solar and wind farms; the company has commercially deployed 30 kWh and 100 kWh units for residential applications and completed production of its MWh system for large-scale microgrid applications. Led by CEO Dr Avishek Kumar, VFlowTech employs a team of 60 people. The company raised US$10M in a Series A to support scaling and manufacturing. It intends to use the funds to set up a 200 MWh production line capacity and scale manufacturing of its 250 kWh modular vanadium-based long-duration energy storage solutions. VFlowTech also plans to expand its market presence to Türkiye, the US, Japan and India with new partners and to strengthen the management team over the next year. VFlowTech is a Singapore-based energy storage solutions provider that designs and manufactures long-duration modular batteries. Led by co-founder and CEO Dr. Avishek Kumar, the company has developed three modular systems—5 kW/30 kWh, 10 kW/100 kWh and 100 kW/500 kWh—that can be scaled to multi‑MWh deployments. A 10 kW/100 kWh system can provide up to two days of energy autonomy for small households and remote communities, the company says. In the past year VFlowTech has been delivering solutions to independent power producers, EPCs and other users worldwide and has a pipeline of large-scale infrastructure projects in markets including Australia and Africa. VFlowTech raised US$3M in a Pre‑Series A round and intends to use the funds to expand manufacturing and distribution of its long-duration modular batteries. The company aims to help remote and rural communities transition to low-cost reliable cleantech solutions and become diesel-free.

  • Solu Therapeutics

    Participated · Series A · Apr 2025

    Solu Therapeutics is a biotechnology company pioneering therapies that eliminate disease-driving cells across cancer, immunology, and other therapeutic areas using proprietary CyTAC and TicTAC platforms. Its lead candidate, STX-0712, is a CyTAC designed to target CCR2 and selectively eliminate CCR2-positive malignant monocytes, with an initial focus on CMML and other hematologic malignancies. The company has initiated a first-in-human, open-label, multicenter Phase 1 trial of STX-0712 with a two-part design: Part A dose escalation to determine the maximum tolerated dose and/or minimum effective dose in resistant/refractory CMML, and Part B to evaluate safety, tolerability, recommended Phase 2 dose, and preliminary antitumor activity. Solu presented preclinical ex vivo data at the 2024 ASH Annual Meeting showing robust activity of STX-0712 against CCR2-positive monocytes from CMML patient samples. Proceeds from the recent financing will be used to complete dose escalation and expansion of STX-0712, generate new development candidates including a first-in-class mast cell depletor for immunological diseases, advance additional discovery programs, and explore new applications for the CyTAC and TicTAC platforms. The company was cofounded by Longwood Fund and is based in Boston. Solu Therapeutics is developing therapeutics to eliminate disease-driving cells in cancer, immunology, and autoimmunity using its proprietary CyTaC (Cytotoxicity Targeting Chimera) platform. CyTaC molecules, licensed from GSK, aim to unlock antibody-intractable cell surface targets and combine the potency of biologics with the broad target binding of small molecules. Characteristics of the platform include unlocking new tumor-associated antigens to eliminate cancer cells, depleting pathogenic immune cells, and extending the half-life of small-molecule antagonists and agonists. The company intends to use the financing to develop the proprietary CyTaC platform and associated drug candidates in-licensed from GSK. Under the license, GSK received equity in Solu and will receive milestones and royalties on products derived from the CyTaC platform. Solu is led by co-founder and CEO David Donabedian, Ph.D., and is based in Boston, MA.

  • EarthOptics

    Participated · Equity · Nov 2024

    EarthOptics leverages advances in soil-sensing technologies, genomics, and data science to deliver predictive insights into chemical, physical, and biological soil properties. It combines lab-based analysis with field-based sensors to give farmers and ranchers actionable recommendations to optimize spending and unlock sustainable farming opportunities. The company completed a strategic merger with Pattern Ag, combining EarthOptics’ proprietary field-based sensing technologies with Pattern Ag’s lab-based analysis to offer comprehensive soil data. Led by CEO Lars Dyrud, EarthOptics operates offices in Raleigh, North Carolina; Emeryville, California; Arlington and Blacksburg, Virginia; Minneapolis, Minnesota; and Fayetteville, Arkansas, and maintains two laboratories in Emeryville and Memphis, Tennessee. The company intends to use new funding to accelerate technological innovation, broaden its geographic reach, and consolidate its position as an authoritative source for soil insights. EarthOptics develops next-generation soil-sensing technologies that combine ground-based sensors, satellites, physical soil samples, machine learning models, and agronomic expertise to deliver detailed soil measurements. The company's platform provides insights to help farmers optimize fertilizer applications, inform tillage decisions, and quantify carbon sequestration. EarthOptics plans to use its latest funding to expand access to its tools and deliver hyper-accurate soil insights. Founded in 2018 and based in Arlington, VA, the company serves growers and ranchers seeking data-driven land-management decisions. The company is led by CEO Lars Dyrud. The article reports a recent financing that will support its growth and product expansion efforts. EarthOptics has developed an imaging suite that uses ground-penetrating radar and electromagnetic induction to produce deep maps of soil physical and chemical composition. Its commercial products, GroundOwl and C-Mapper (C for carbon), reconcile no-contact sensor data with traditional lab samples via machine learning trained on tens of thousands of ground-truth measurements. The hardware can be mounted on ordinary tractors or trucks and pulls readings every few feet, reducing physical sampling from hundreds of samples to dozens. The company’s outputs can be used to create meter-scale treatment maps or to feed variable-depth robotic field machinery such as smart tillers. Management positions the product as a cheaper, faster, and more precise alternative to traditional soil sampling and as foundational data for automated and robotic farming. Financially, EarthOptics raised a $10.3M A round to scale its two existing products and to develop a moisture-mapping product.
