  • Data science teams are expensive, and many small or midsize businesses don't have resources (or a need) to employ one full time.

  • Having unlimited access to a statistician or data scientist at a low-risk, predictable monthly fee can give you assurance and reduce headaches in those times it is needed, leading to quicker turn around.

  • Staying plugged in through asynchronous communication means we can keep a consistent pulse on your goals, which accelerates alignment on bigger projects.

  • An ongoing relationship elicits active partnership, giving the ability to be proactive and future-oriented, rather than just trying to band-aid immediate solutions.

  • Did we mention the discounted rates?
