Solving Critical Data Challenges. Sustaining open source.

We deliver engineering expertise and high-value solutions for organizations, while ensuring the open source ecosystems we all depend on are healthy and resilient.

Trusted By

We help organizations build on open source and strengthen it.

Organizations rely on open source software to innovate, but many struggle to engage sustainably with the communities behind the projects they depend on. Quansight exists to bridge that gap.

Our team of software developers, community leaders, technical writers, and designers actively maintain and contribute to more than 40 open source projects, including CPython, NumPy, Jupyter, conda-forge, Polars, and stdlib.js. We partner with engineering, product, and research teams to solve complex technical challenges, accelerate development, reduce risk, and unlock new value across the PyData ecosystem.

At the same time, we ensure that this work strengthens the health, resilience, and long-term sustainability of the open source projects and communities our customers rely on. We believe commercial success and community sustainability should reinforce each other — and we help organizations achieve both.

Client Testimonials

“A colleague from the Pangeo community opened up the sky for us when they recommended Quansight do the hard work of updating Pandas so it could allow non-nanosecond time resolution, which is crucial to our field (paleoclimatology). We were pleasantly surprised when the reviews of our proposal to the National Science Foundation expressed great support for this collaboration, which helped get the project funded.” , USC

"Quansight was amazing to work with. They helped us select and implement an open source technology stack that enabled us to cost-effectively process terabytes of data per day. Not only that, but they automated the deployment process, untethering us from specific cloud vendors, and enabling us to shop for competitive rates."

"It became immediately apparent at how knowledgeable the workforce is at Quansight. They are leaders in their field of AI, machine learning, and reinforcement learning, and take pride in their work. Their vast knowledge paired with their responsiveness and dedication made working with them a smart choice and pleasurable experience."

"We engaged Quansight with some Jupyter, Python team development, data visualization skills in hand. Quansight helped us refine these skills by offering guidance in establishing our best practices, but more important to our long term analytical success, they helped us build a strategy around the use and deployment of these tools."

Why Organizations Choose Quansight

1. Deep Technical Expertise

Our team includes maintainers, core contributors, and long-time practitioners across the PyData and broader open source ecosystem. This deep OSS experience means we don’t just build solutions, we follow established development, packaging, and security best practices from the start, reducing risk and ensuring long-term maintainability.

2. A Complete Consulting Model

Our consulting approach considers the full context of how software is built, used, and sustained, spanning user experience (UX), developer experience (DevEx), documentation, accessibility, and community impact. Especially in our open source services, we design solutions that are usable, adoptable, and aligned with real-world workflows.

3. Ecosystem Impact

We actively contribute upstream to open source projects when it makes sense, strengthening the tools and ecosystems our clients rely on. Beyond direct contributions, we reinvest our success into the community through our open source internship program, OSS funding initiatives, and sustained project maintenance, helping ensure long-term ecosystem health.
