About
Callosum is a London-based AI infrastructure startup founded by Cambridge neuroscientists who applied their understanding of how the brain orchestrates computation across specialized regions to the problem of multi-vendor AI chip coordination. The company's name references the corpus callosum—the brain structure that connects and coordinates the two cerebral hemispheres—reflecting its technical mission: enabling different AI accelerators from different vendors to work together efficiently as a unified compute resource. Callosum addresses a real pain point for enterprises and cloud providers that now operate heterogeneous fleets of GPUs, TPUs, and custom silicon.\n\nCallosum's orchestration platform abstracts over hardware differences between AI chip vendors, allowing workloads to be scheduled and balanced across NVIDIA, AMD, Intel, and custom accelerators without manual optimization for each chip type. This is particularly valuable as enterprises seek to reduce vendor lock-in and optimize cost by mixing and matching hardware. The platform targets ML engineering teams and infrastructure operators at companies running large-scale AI training and inference workloads who need to maximize utilization across a diverse hardware estate.\n\nCallosum raised $10.25M in February 2026 in a seed or early-stage round, providing capital to build out its engineering team and deepen integrations with major chip platforms. While early in its journey, the company operates at a genuinely important intersection: as AI chip diversity grows and no single vendor dominates all workloads, the need for intelligent multi-vendor orchestration will only increase. Callosum's neuroscience-rooted technical vision and Cambridge pedigree give it a distinctive angle in the competitive AI infrastructure space.
AI photo/video editing platform with 150M+ MAUs and 2.5B lifetime downloads; $195M total funding at $1B+ valuation; launched AI Playground with 90+ models
About
Picsart is a global AI-powered photo and video editing platform founded in 2011 by Hovhannes Avoyan in Armenia, now headquartered in Miami. The company was built on a community-first model that combined editing tools with a social sharing layer, allowing creators to discover, remix, and build on each other's work. Over 13 years, Picsart evolved from a mobile photo editor into a comprehensive creative platform that serves both individual creators and enterprise customers across photo editing, video editing, design, and generative AI tools. The company has accumulated 2.5 billion lifetime downloads across its mobile and web applications.\n\nPicsart's platform now includes an AI Playground with 90+ generative AI models covering image generation, background removal, object replacement, style transfer, video editing, and design automation. The company positions itself as an accessible alternative to Adobe Creative Cloud for creators who need powerful AI-enhanced tools without a professional design background. Enterprise products target marketing and creative teams at brands and agencies who need to produce visual content at scale. Picsart's AI features are built on a combination of proprietary models and integrations with third-party foundation models.\n\nPicsart has 150M+ monthly active users and raised $195M in total funding at a $1B+ valuation, with investors including Sequoia Capital Armenia, SoftBank Vision Fund 2, and Insight Partners. The company's scale in developing markets — particularly in Southeast Asia, Latin America, and Eastern Europe — differentiates it from Western-focused creative tools and gives it a diverse global creator base. Picsart is navigating the generative AI transition by integrating AI capabilities directly into its existing user workflows rather than launching a separate AI product.
