  • Bounti.ai

    Participated · Seed · Sep 2024

    Bounti offers the world’s first full-stack and funnel agentic AI teammate platform designed to increase efficiency and productivity for sales, marketing, and customer success teams. Its first teammate specializes in prospecting and automates research and personalization at scale, reducing time spent on mundane tasks and enabling more authentic customer engagement. The company pairs cutting-edge software with a human-in-the-loop services component to accelerate revenue outcomes and provide trained sales expertise alongside the product. Bounti emerged from stealth while building a strong enterprise customer pipeline and delivering application-layer value. The team says it will use new funding to expand capabilities across both the software platform and the human-in-the-loop services offering. Silicon Valley veteran Lew Cirne has been named the company’s first independent board member.

    Participated · Seed · Sep 2024

    Bounti builds a full-stack, full-funnel agentic AI teammate platform that automates research, personalization, and prospecting to augment sales, marketing, and customer success teams. Its first teammate specializes in prospecting and uses a research-first approach and a streaming LLM architecture to deliver up-to-date buyer identification and personalized outreach at scale. The product can research hundreds of companies in minutes (the company cites 500+ companies researched within ten minutes and hundreds within five minutes for one rep) and offers options to serve highly personalized outreach or fully outsource prospecting to Bounti’s trained sales professionals. Bounti emphasizes a human-in-the-loop model, pairing cutting-edge software with experienced sales practitioners rather than fully replacing human contributors. The company came out of stealth and reports a rapid development of an enterprise customer pipeline and delivery of tangible application-layer value. It plans to use the new funding to invest aggressively in expanding capabilities across both the software platform and its human-in-the-loop services component.

  • Relectrify

    Participated · Equity · May 2024

    Relectrify engineers CellSwitch™, a cell-level control electronics and software platform that manages individual battery cells to extract more energy and extend operational life by up to 30 percent. The technology can eliminate conventional inverters, lowering CAPEX and reducing failure and safety risks. Relectrify has completed industrial-scale rollouts and works with global customers, partners and battery manufacturers. Its IP is protected by over 30 granted and pending patents across the US, Canada, Europe, South Korea, China and Japan. The company is headquartered in Melbourne, Australia, and the new funding is intended to scale the CellSwitch technology into international battery storage markets. Clean Energy Finance Corporation has been a notable investor, with total commitments reported in the article. Relectrify has developed a cell-level battery management system that can produce a high-efficiency AC output directly from the battery pack, replacing a separate inverter. Its BMS+Inverter architecture reportedly extends battery lifetime by up to 30% while reducing electronics cost by around 30%. The solution supports new and second-life Li-ion and alternative chemistry batteries and has been demonstrated with customers including American Electric Power, Nissan North America and Counties Energy. The company commercialises both embedded implementations with BESS manufacturers and circular-economy second-life systems such as the ReVolve™, a 120 kWh / 36 kW BESS using repurposed Nissan Leaf cells. Relectrify is expanding its commercialisation team and forming partnerships in the US, EU and Asia while continuing R&D to extend its cell-based control technology. The company reports an increasing pipeline of commercial projects and multi-MWh rollouts of ReVolve™ systems. Relectrify builds battery and inverter systems that reuse second‑life electric vehicle battery packs, combining hardware and software in an advanced BMS+Inverter battery control technology. The company is launching a 36 kW / 120 kWh commercial-scale modular battery product roughly ten times the size of a Tesla Powerwall 2. Its technology, developed with ARENA support in 2018, is designed to boost battery lifetime and performance while reducing system costs. Relectrify is executing a $3.3 million project to finalise development, undertake certifications and roll out 20 battery units across commercial and industrial customer applications in Australia. The company will offer units to selected utilities, industry and community customers, both grid-connected and off-grid, for applications including solar integration, backup power for farms and microgrids, deferring network upgrades, and replacing diesel generators. ARENA has provided $1.49 million in funding from the Australian Government to advance the project. Relectrify develops technology to repurpose used electric-vehicle (EV) batteries for behind-the-meter household energy storage. Its system combines power-electronics hardware with battery-optimisation software to reduce repurposing costs while boosting performance and extending battery lifetime. The company notes that up to 80% of an EV battery’s storage capability can remain after it is no longer suitable for driving, and many cells can be charged and discharged a further 2,000 times. Relectrify plans to expand production and conduct commercial trials of second-life batteries with the aim of becoming a global leader. Financially, it secured a $750,000 early-stage equity investment from the Clean Energy Innovation Fund as part of a $1.5 million pre-Series A equity raise. Co-founded by Daniel Crowley and Valentin Muenzel in 2015, the Melbourne-based company is an alumnus of the University of Melbourne’s Melbourne Accelerator.

  • Umedeor

    Participated · Equity · Jul 2023

    uMed is a London-based health tech company whose platform helps healthcare institutions identify, screen and engage specific patient cohorts for clinical trials, registries and population health initiatives. The platform leverages health-record data to target patient groups and automates communication, including collection of patient-reported outcomes. By taking on identification and outreach work, uMed reduces administrative burden on healthcare providers and facilitates their participation in research programmes. The company says its patient cohorts provide researchers with unique data and insights while cutting the cost of finding, engaging and collecting prospective patient data. uMed raised £9.8 million in a new funding round and intends to use the capital to ramp up UK-focused efforts and expand its presence in North America. The raise was positioned as a response to collapsing patient access to industry clinical trials in the NHS. uMed is a London-based technology platform embedded in a global network of healthcare providers that automates the creation of high-quality prospective research registries. Its platform can reach back compliantly from the electronic health record (EHR) to patients, enable e-consent, and capture structured outcomes remotely while protecting patient data and ensuring regulatory compliance. The company is already deployed across over 160 primary care sites in the UK, representing more than 1.7 million patients, and expects to serve 2 million patients from a large US health system from early next year. uMed's tools are used in clinical studies such as the University of Oxford–led RAPTOR-C19 study within the national CONDOR platform and support remote data capture linked to patient records. The technology is positioned to reduce manual costs in research workflows and allow small GP practices and large hospitals to participate in multiple research programmes without increasing clinical burden.
