Slingshot AI is a New York- and London-based startup developing the world's first foundation model for psychology to make mental healthcare more accessible amid a global crisis.[1][2][5] The company builds Ash, an AI chatbot (voice/text) trained on the largest behavioral health dataset, serving individuals seeking long-term mental health support by identifying patterns, offering evidence-based guidance, and helping users achieve goals—addressing the 10,000:1 demand-to-provider gap.[2][3][5] With $93 million raised (including a $30M seed led by a16z and a Series A bringing total to $40M+), Slingshot has tested models in a 20K+ user private beta, achieving Series A status and $220M valuation, fueled by rapid iteration on high-performance GPU clusters.[2][3][4][6]
Slingshot AI was co-founded in 2022 by Neil Parikh and Daniel Cahn. Parikh, Casper co-founder, dropped out of medical school, scaled Casper to $500M+ revenue and IPO (with 7 patents in sleep/robotics), bringing operational expertise.[2][6] Cahn, a high-school dropout ML engineer, earned "distinguished" status from Imperial College for AI mental health research and prior crisis tech experience.[2][6] The idea crystallized in January 2024, launching Ash as the first psychology foundation model after 18 months of training on diverse datasets (beyond CBT wrappers), rejecting one-size-fits-all therapy like ELIZA.[2][5][6] Early traction included a private beta with 20K+ users and quick product launch, securing $30M seed (a16z-led, Menlo follow-on) amid investor buzz.[1][3]
Slingshot stands out in mental health AI through:
Slingshot rides the generative AI wave transforming therapy from rigid bots to empathetic, scalable support, as LLMs enable data-scale learning of diverse psychologies amid worsening mental health (half the world affected, provider shortages).[5][6][7] Timing aligns with post-2023 AI leaps making "bot therapy" viable, shifting from historical skepticism to daily engagement.[6] Market tailwinds include exploding demand, investor bets on consumer health giants, and compute access (e.g., Nebius GPUs).[2][6] It influences the ecosystem by pioneering domain-specific foundation models, validating AI for behavioral science, and democratizing care—potentially inspiring bio-AI crossovers.[6]
Slingshot is poised to scale Ash globally via clinical trials, regulatory nods, and expanded datasets, leveraging $93M for R&D/marketing toward mass adoption.[3][4] Trends like multimodal AI (voice+text), personalized health LLMs, and hybrid human-AI care will propel it, evolving from beta to ubiquitous support app. As mental health crises persist, Slingshot could redefine accessibility, fulfilling its manifesto to help everyone uniquely—cementing its role as the psychology AI pioneer that bridges tech and human well-being.[2][5][6]
Slingshot AI has raised $83.0M across 2 funding rounds. Most recently, it raised $53.0M Series A in July 2025.
