Data science is as much a scientific and creative process as it is an engineering one. It involves working together, failing, learning and going back to the drawing board. Data scientists are explorers. To make data projects successful, we need tools that are both powerful and easy to use. Tools that help us collaborate and share our work in an engaging way. Tools that make data science fun again. At Deepnote, we’re building a new standard in data tooling — a notebook that brings teams together to explore, analyze and present data from start to finish. We are building tools for explorers. Join us.

In production, we're already seeing a reduction in time spent triaging, investigating, and resolving alerts with some of the fastest growing companies in the world.

Defer enables Node.js developers to move slow code out of the user's journey. Its simple and well-documented API enables developers to improve web applications' performance in a few minutes instead of days. Bryan and Charly noticed that all companies end up building similar abstractions and dashboards over the existing open-source (BullMQ) or commercial solutions (AWS SQS + Lambdas) to support background jobs, CRONs, and workflows. Defer brings a full-featured and managed platform with a Vercel-like developer experience that comes with an operational dashboard, enabling developers to focus on product work. After building the self-serve version of Defer in 8 weeks and onboarding 5 paying customers, their recent HN launch brought 250+ users and a warm welcome from the Node.js community with the 2 biggest newsletters featuring Defer and tech influencers spreading the word. Defer is now available as a Node.js solution but aims to become a cross-language reference.
