Every ecommerce owner wants the same answer: where did this sale come from? So you buy the dashboard that promises 99% attribution. Then you spend the next year arguing about the gap, because in practice that number sits somewhere between 50% and 99% and never stays still.

We have run those reports. We have had those arguments. Attribution is a fight about yesterday. The question that grows a store is the opposite one: who is your next customer, and what will they order?

Butterstreet turns your commerce data into customer intelligence you can act on, not another dashboard to read. That comes first. Then, as an optional add-on, you connect it to your marketing automation, Klaviyo, ActiveCampaign or your favorite tool, so the right message reaches the right customer at the right moment.

01

Dashboard set up for you

We turn your orders, products and customers into a working DataBull dashboard, so you do not start with exports.

02

Next orders made visible

You see which customers are likely to reorder, who is late and which product combinations deserve attention.

03

Action without homework

The signals are ready for follow-up. First you see them. Then, when it makes sense, we connect them to your marketing automation.

01 The problem

Most of what your store knows, it never tells you.

Be honest. Without exporting anything, can you name the product that made you the most money last month? The two items that keep getting bought together? The customers who are about to reorder, and the ones quietly drifting away? Most owners cannot, and it is not for lack of skill. The answers sit locked in systems that were never built to tell you. So you trust your gut, and your gut is good. It just cannot see what is trending up before your competitor does, or what people keep looking at and never buy.

▸ WHAT SELLS

Your fast sellers, live

Top products and product pairs without an afternoon in a spreadsheet.

▸ WHO IS LATE

Reorder timing

The customer who buys every 9 weeks and is now at week 12.

▸ WHAT IS COMING

Demand ahead

Seasonal patterns and product movement before the buy, not after the miss.

02 The proof
DataBull · customer intelligence layer

Your own data, finally legible enough to act on.

And none of it is guesswork. Google Analytics samples and estimates. DataBull works from your own first-party data, the real orders, products, customers and stock already in your systems, and makes it legible: what is moving, who is late, what sells together, and where tomorrow's demand is starting to show.

04 Our story

From web agency to data agency.

We did not arrive at data from a consulting deck. We got here by running ecommerce, counting stock, and answering customers, and we saw that the real value is rarely in the store itself. It is in the data underneath it.

What does Butterstreet 21 do?

DataBull is customer intelligence and statistical ecommerce tooling. It uses behavior, cohorts, product combinations, reorder intervals, and customer rhythm rather than AI hype.
