Skyhook

PaaS-like experience with the power of Kubernetes, on your cloud

We make running services on Kubernetes as easy as Heroku, but on your cloud and with all the flexibility and power of Kubernetes. Companies use Skyhook so that they don't have to hire dedicated infrastructure engineers. Although 50-70% of organizations have already adopted Kubernetes, most developers agree that it is too complex and difficult to manage. It is intended to be extremely flexible in order to solve pretty much everyone’s needs, but it can take a ton of work and many auxiliary tools to get there. As companies grow, they spend a lot on DevOps or Platform Engineers that try to reduce the burden on developers by gluing together all the 3p tools via custom internal tools. We are building an “internal developer platform” out of the box, with best practices and golden paths for building and operating services on Kubernetes. We do the research on the latest and greatest tools in the extremely vibrant ecosystem, and automatically integrate for you the tools you want to use. We operate on our customers code and in your Cloud environment, so they never locked in and never restricted, as is common with classic PaaS offerings. If you prefer a fully hosted environment like Heroku, Fly or Vercel, we’ll host a cluster for you and offer you a one-click migration to your own cluster when you want.

Skyscrape logo

Skyscrape

Skyscrape makes temperature-responsive insulation

Skyscrape makes temperature responsive fabrics for a new type of clothing. These fabrics literally change shape in response to a change in temperature: the fabrics become thicker and insulate more as the temperature drops, and they become thinner and insulate less as the temperature rises again. This "intelligent insulation" has no wires or sensors, and the fabric's shape-changing behavior comes from a natural materials response. Skyscrape’s fabrics offer expanded thermal comfort across a wider temperature range than conventional clothing. Creating textiles that could change shape with changing temperatures required years of laboratory work by an interdisciplinary team of scientists, engineers, designers, and weavers, designing and refining machines and processes to make yarns and fabrics that could adapt to the environment. Skyscrape's first market entry was with Ralph Lauren in the 2022 Team USA Winter Olympics Opening Ceremony.
