Church & Duncan Group Inc.

Deep data science and machine learning consulting group changing the world through data with love, care, and dedication from San Francisco .

Our Mission

Transform and empower organizations through data, science, and technology.

The Digital Revolution is swiping every industry and every corner of the world. Yet, advanced technology is far from accessible and requires a lot of expertise to achieve valuable results. Being trained in AI / Data Science before it became a buzzword and truly understanding how things work, we think that it is our responsibility to support and empower as many organizations as we can with this powerful innovation.

For example, we developed a resume scoring solution for SuperJob saving thousands of hours for recruiters accross the world, we helped fight spam for Odnoklassniki and Yandex, we automated social media marketing for Youscan, and many more. Yet, we believe that our journey is 1% done. Contact us and let us improve your organization!

Our Principles

Attract and develop the best talent. Use the best tools. Work with the best organizations. Work hard. Have fun!

Famously, Steve Jobs once said: "A players hire A players; B players hire C players; and C players hire D players. It doesn't take long to get to Z players.". We deeply believe in these words and aim for the best at everything we do, including hiring, culture, processes, and work for clients. To accomplish it, we use the best tools, apply the best frameworks, and hire the best people making them happy with challenging fun projects.

Extending this further and acknowledging the fact that our social and professional connections define who we are ["Connected", Christakis & Fowler, 2011], we aim to work with the best organizations on meaningful high-impact problems. Otherwise, it is not that difficult to become a legacy organization without principles and passion for work.

Our Advantage

Bringing the cutting edge technology and knowledge to businesses by staying tight with the academic community.

Coming from the academic world, we understand the value of basic research. Yet, our industry and consulting experience have tought us that basic research need to be customized and adapted before it hits the clients expecting crisp results. We provide this complex missing link by spending an enormous amount of time on reading academic papers, extracting insights, and repackaging them into pragmatic business solutions.

For example, in the last several years, the field of AI and deep learning has been booming and crazily expanding. We took a deep dive ourselves, processed tons of papers and talks, and attended every single top tier conference on the topic. As a result, we've developed a consciece immersive 0 to 100% "Deep Learning Deep Dive" training.

Thought leadership for creative executives.
