Our Mission

We believe that the transition from traditional software to AI is one of the most important shifts of our time. Our mission is to make that happen faster, across every industry. One of the biggest bottlenecks for real world AI applications is access to labeled data. Our first product is the most developer-friendly data labeling API for AI applications: self-driving cars, mapping, AR/VR, robotics, drones, retail, and more. Our products for image annotation, semantic segmentation, 3D point cloud annotation, and LIDAR and RADAR annotation are used by industry leaders and provide world-class accuracy. Our view is that the most impactful way for us to change the future 10 years from now is by fundamentally bending the growth curve of machine learning software. If we make it easier and more feasible to build machine learning software, we can accelerate progress across every field in machine learning. WHY SCALE? - Our team is transforming how machine learning teams build innovative products. - We're a collaborative team that's always taking on complex challenges and finding new ways to solve problems. - We believe in empowering each individual while fostering collaboration to achieve success, and together, we are accelerating the development of AI applications. To date, Scale has raised $22.7 million in funding, with its latest funding round being a Series B in 2018. We have 65 people on our team, and we come from all different backgrounds. Scale's team is composed of educators, parents, poker players, boba lovers, and more. Coming out of YC S16, we have been able to partner with industry leaders to accelerate their AI development.

Tech Stack

Our first product is a suite of APIs that allow AI teams to generate high-quality ground truth data. Our customers include Alphabet (Google), Zoox, Lyft, Pinterest, Airbnb, nuTonomy, and many more, and we've become an industry standard for the self-driving car market. We are building a large hybrid human-machine system in service of ML pipelines for dozens of industry-leading customers. We currently complete millions of tasks a month, and will grow to complete billions of tasks monthly. Deep Learning: building CNNs. Classical Machine Learning: non-deep learning methods (random forests, collaborative filtering, HMMs, etc.) Applied ML Engineering: building large-scale data and machine-learning pipelines. ML Frameworks: TensorFlow, Pytorch Web Stack: React, Javascript, Node.js, Next.js, MongoDB

Core Values

Our values ensure we are aligned in executing on our mission. These core values provide a framework for us to make decisions and work effectively as a team: SOLVE PROBLEMS We hire problem-solvers in every role. We hire people who can identify & solve problems as they arise, and push themselves to solve these problems better and better over time in novel ways. This enables every part of the company to continuously self-improve and confront difficult problems on their own. These improvements will compound exponentially and make a massive difference over any period of time. BE THE CHANGE At any one time, there are going to be areas of improvement and problems in need of solving. While it can be tempting to enumerate these problems, the real magic happens when you take action and drive improvement. Across the company, we are empowered to devise and drive solutions, no matter if it's in "our area" or not. With everyone's contribution, we'll notice that everything, no matter in what state, will steadily improve. OPTIMISM IS INFECTIOUS By being optimistic about an outcome, we greatly improve our chances of success. At Scale, we are constantly in the process of making something from nothing. As we work on novel and cutting edge solutions, we are optimistic about the future and optimism is infectious. TRUST AND INVEST IN THE TEAM We all succeed or fail as a team, and no individual is greater than the team. We make an effort to constantly trust and invest in each other to build a robust, scalable company.
