Our mission is to help people make decisions they love, instantly. We're tackling the most economically impactful decisions first: the average shopping journey takes 79 days, and we're taking that to less than 1. Since our public launch in late 2023, we've grown exponentially to guide millions of users to their perfect product. We recently built the foundation of a neurosymbolic AI agent that learns more about the world on every search. This breakthrough dramatically increases search accuracy, opens up new categories, and propels us towards a world where making a decision is as well-informed as asking an expert and easy as asking a friend.

Massive powers live web access for the AI era. We run a network of real consumer devices across 195+ countries, each one opted in through our SDK, so data and AI teams can fetch live public-web content at scale from any location, exactly as a real local user would. On top of that network sit our residential proxies and the Web Render API: clean HTML or markdown from any public source, a Search endpoint for SERP and local results, and AI completions from any geo with sources.

In an increasingly digital world, MemoryWell is solving a growing list of healthcare’s most challenging engagement problems with an unexpected solution: Empathetic, human interaction. Our solutions make the person the center of healthcare. MemoryWell delivers dramatic increases in satisfaction and retention. And our rich, person-centered dialogs yield the most accurate SDOH and HRA data available. MemoryWell grew out of the experience our founder, Jay Newton-Small, had caregiving for her father, who had Alzheimer's. When she moved him into a senior community, she was asked to fill out a long questionnaire about his life. This made no sense: who would remember pages of hand-written data points for 100+ residents in that community? Instead, as a longtime TIME Magazine correspondent, she wrote his story for his caregivers and pasted it on the walls throughout the community. It transformed his care. Two of his caregivers were Ethiopian and they'd had no idea Jay’s father, Graham, had lived in Ethiopia for years early on in his career with the United Nations. They became his champions, sitting for hours asking him about what it was like to work with Emperor Haile Selassie. Seeing the impact her story had on her father’s experience was enough to influence Jay to transition from her role at TIME to launch MemoryWell. In addition to the life stories product, MemoryWell has leveraged insights and journalistic engagement to reduce churn in Medicare Advantage. Medicare Advantage churn averages 10% and is as high as 40% during the first 90 days. Enrollees have grown numb to automated texts and robocalls, resulting in expensive data gaps. MemoryWell provides human-to-human engagement that resolves these problems with skillful conversation, relationship building, and education.
