The Celerio Method is the body of knowledge underneath GTM Value Engineering: a measurement-and-inference framework that models the revenue system as two processes, the seller-side funnel it estimates and the buyer-side belief it infers, and allocates the binding constraint, founder attention, across them.
A revenue system is a process
A deal occupies an ordered sequence of states. The Method estimates three coefficients between them, conversion, velocity, and value, from the firm's own won-and-lost record rather than an inherited canon, at the finest level the evidence supports, and it holds each as a distribution with honest uncertainty rather than a false constant.
Two processes, one control loop
The seller process is estimated from outcomes. The buyer process, how belief forms inside the buying group, is not in the firm's records, so it is inferred from signal: the vocabulary and criteria a buyer speaks betray whose frame they have absorbed. The two are two ends of one control loop, and the buyer-side instrument is the early estimator of the seller-side conversion.
Two motions, and the diagnosis between them
Where demand already exists, the Method runs the qualification motion, MEDDIC, instrumented against evidence. Where the category is nascent and demand must be made, it runs the creation motion, Challenger, measured by frame-movement. The distinctive contribution is the diagnosis that tells a team which motion the situation demands. It is the demand-native successor to MEDDIC: qualification gives way to influence-modelling.
Denominated in attention
At firm scale the binding constraint is founder attention, and the Method allocates it to the decisions with the highest expected value of being made well. That is why it underpins the attention supply chain and the discipline that engineers it, GTM Value Engineering.
