Deal Strategy
The death of the vendor pitch deck
Here is what often happens when a pitch deck lands in a buyer's inbox.
They open it. They skip the company slide and the logo bar. They land on a line such as "save 40% on operational costs," in a large type size, with no formula under it. They think: says who? They close it.
That is not a design problem. The format was built for a meeting where the vendor controlled the information. That meeting is no longer the whole process.
97%
of technology buying decision makers reported using a business case to justify a purchase, and named it the most useful format for the decision. Long-established, self-reported, global enterprise sample. It says the format is expected. It does not say a better case wins the deal.

Finance is in the room more often now as well. In G2's 2026 Buyer Behavior Report, finance involvement in software decisions rose from 31% to 46% in a single year (1,038 B2B software decision-makers, June 2026). Pair the older figure with that newer one. Neither is a Serre result, and neither is a reason to claim we prevent a veto.
Why the format stopped working
Today's buyer has usually done some of the reading before the first meeting. By the time the deck arrives, a slide that says "industry-leading" and "proven ROI" is interchangeable with the last vendor's slide. Swap the logo and a procurement reader often could not tell them apart.
The procurement test
If a reader swapped your logo for another vendor's, would the deck still say the same thing? If it would, the deck is not carrying the argument.
The deck also cannot answer the question the champion gets asked later: where does this number come from, and what happens if the assumption is wrong?
What the buyer can actually use
Your champion is not a salesperson. They have to explain a spend to people who were not in your meeting. A deck asks them to sell. A case with visible formulas, named assumptions and a range lets them walk through a projection.
The figure on the page should be labeled as a projection. An illustrative "$1.8 million" with no formula is the same problem as the deck, just in a different file.
A pitch deck asks your champion to be a salesperson. A case they can open lets them be the person who checked the math.
A different artifact
The replacement is not a better-looking deck. It is a case for change: the buyer's situation, the proposed change, the assumptions, and a projection the committee can examine. One argument for the group, not a different story for each person in it.
Serre is built for that work. Value engineering for every seller, with the guidance in the product and a person approving what the company is willing to claim. Turn every deal into a defensible case for change. We do not claim that this stops a "no decision," raises a win rate, or shortens a cycle. Those are outcomes we have not measured.
The useful question is whether the buyer can examine the case without you in the room. A deck that only restates the pitch does not give them that.
