Proof of Concept

Also called POC

A proof of concept: a limited, time-boxed trial where a prospect tests whether your product actually solves their problem in their environment before committing to buy.

Why it matters

A POC de-risks a purchase for the buyer and can accelerate a deal, but a vague one drags on forever and ties up your team. Defining clear success criteria upfront is what keeps a POC from becoming free consulting.

For example

A prospect runs a two-week proof of concept on their own data to confirm the tool actually solves the problem before signing.

It gives you the five things a real pilot or LOI agreement must contain (measurable objective, timeline, success metric, each party's duties, exit clause) so the paper you put in your data room signals genuine pull, not a friendly forward. Its best rule for a pre-traction founder: make the customer commit time or money, because an LOI where a senior buyer agrees to weekly check-ins is worth ten polite 'looks interesting' emails.
