Sound familiar?

› You're making pricing decisions on gut feel because you don't have time to actually test them.
› You ran a marketing campaign and still can't say what it actually returned.
› Your sales data lives in your POS system, a spreadsheet, and your head — not in one place you can trust.
› You're guessing at how much inventory to order instead of forecasting from real demand patterns.
› You need a real answer to one specific question, not an ongoing analytics contract.

What you get

›Sales & customer trend analysis
›Marketing ROI & attribution analysis
›Pricing analysis & A/B testing
›Demand forecasting & inventory planning
›Data cleaning across POS, CRM, and spreadsheets
›Plain-English findings, not a stats lecture
›A fixed-scope quote before any work begins
›One-time projects or ongoing check-ins — your call

Where this shows up in our work

DASS's day-to-day work is large-scale funded research, but the underlying skills transfer directly: automating reporting so nobody re-builds a spreadsheet by hand every month, and testing whether a change actually moved the numbers. Same discipline, smaller scale.

We had an unrealistically tight timeline, and Dr. Yel jumped in without hesitation — not only met the deadline, but delivered a little earlier than we anticipated. He took the time to understand the situation behind the data and the implications of every insight. We know who to go to for future work like this.

DASS did a fantastic job. They were patient, clear about the coding, and very responsive to my emails. They took the time to understand the overall goal before proceeding with each step. Highly recommend.
