Since 2017, the number of Python users has been increasing by millions annually. The vast majority of these people leverage Python as a tool to solve problems at work. Our mission is to make them autonomous when they create and use data in their organizations. For this end, we are building an open source Python library called data load tool (dlt). Our users use dlt in their Python scripts to turn messy, unstructured data into regularly updated datasets. It empowers them to create highly scalable, easy to maintain, straightforward to deploy data pipelines without having to wait for help from a data engineer. We are dedicated to keeping dlt an open source project surrounded by a vibrant, engaged community. To make this sustainable, dltHub stewards dlt while also offering additional software and services that generate revenue (similar to what GitHub does with Git). dltHub is based in Berlin and New York City. It was founded by data and machine learning veterans. We are backed by Dig Ventures and many technical founders from companies such as Hugging Face, Instana, Matillion, Miro, and Rasa.

OAK (On-chain Autonomous Kernel) Network is an automation layer-2 blockchain for Defi and recurring payments. Our mission is to build a Stripe for Web 3.0 across protocols. The blockchain is built on Parity Substrate with an event-driven execution model. Different from Ethereum’s transaction-based model, where a transaction requires private key signing, OAK allows transactions to be triggered by event signals such as time, price, and smart contract state changes.
