The week-four check-in on a proof of concept lasts eleven minutes. According to the buyer's operations manager, her team likes the tool, but two people took time off. She asks to extend it two more weeks, and the AE agrees before she finishes the sentence. Saying yes feels safer to him than asking what "likes it" actually means.
Nobody on the call mentions the admin console, which shows most pilot users logged in twice during kickoff week. The success criteria never come up either, since the team discussed them on a discovery call in August and nobody wrote them down. Meanwhile, the steering committee from the kickoff slide has not met since, and the AE quietly stopped sending it updates.
Pilots that drift like this usually end with a polite no in December or a second extension in January. The failure started before kickoff, when the AE agreed to a trial without a written finish line. Whether a pilot ends in a decision is something the AE settles on the call before anyone logs in.
A proof of concept is a short, time-boxed test of whether a product solves one specific problem before the buyer signs. In software sales, people use the term almost interchangeably with pilot. Strictly speaking, a pilot puts real users on real work for a set period. A proof of concept can be narrower, such as a technical test run by two or three engineers.
For the AE, the label matters far less than the ending, which should come on a known date with a decision. A free trial lets someone poke around on their own schedule, and it ends whenever they stop logging in. By contrast, a proof of concept has written criteria, named users, and a decision owner on the buyer's side. That owner also has a readout on her calendar where she says yes or no.
If any of those pieces is missing, the AE is running a free trial with extra meetings attached. The distinction sounds pedantic until a December pipeline review, when the deal shows "in pilot" for the third month. A RevOps lead can fix that by giving trials and proofs of concept separate CRM stages, so the forecast counts only evaluations with a booked decision date.
An extension request is almost never about needing more time. In most cases, the buyer has nothing to decide against, so asking for more time is easier than saying no. Sometimes the champion believes in the product but cannot get her own team to open it. For her, two more weeks postpones the meeting where her boss asks why nobody logged in.
The causes show up in almost every drifting pilot, and each one traces back to kickoff:
The standard advice is to grant the extension and protect the relationship. That advice is usually wrong, because an extension without a new criterion just reruns the same four weeks with less attention. Before agreeing, the AE should ask the champion what would have to be true on the new date and who will say so out loud.
Whoever ran the pilot on the buyer's side eventually sits across from her CFO and has to justify the spend. For AI tools in particular, sales leaders themselves admit that the case is hard to make.
Gartner published the relevant survey in a May 2026 press release. The firm surveyed 227 chief sales officers in August and September 2025. According to the release, 31% of them cited difficulty proving the ROI of AI-driven tools as a top challenge for 2026. So when a sales team pilots an AI product, the person running it may well report to someone with that exact worry.
A vague pilot hands that person nothing to bring upstairs. "The team liked it" dies in the first budget meeting, and a screenshot of login counts says nothing about the business. What the champion needs is a short page that restates the agreed criteria and shows the result for each one. At the bottom, the page should name the decision she recommends.
We covered how to measure AI results without inflating them in our earlier piece on measuring AI agent ROI. A proof of concept needs the same discipline, except the AE has to build it with the buyer before the test begins.
Most sales training tells the AE to let the customer define success. In practice, the customer nods through that conversation and never writes anything down, so the AE should draft the criteria himself. The champion then marks up the draft, because people will edit a half page far more readily than they will fill a blank one.
Go back to the discovery call and find the moment the buyer described the problem in her own words. Maybe she said her managers rebuild a spreadsheet every Sunday night before the Monday meeting. If so, the first criterion should mention that spreadsheet by name. Her team will find it much harder to dismiss criteria written in their own language.
A good criterion describes a change someone on the buyer's team can confirm without the vendor in the room. "Improve visibility" fails that test, and "managers run the Monday meeting from the new view" passes it. Keep the list short, since a pilot with nine criteria usually ends in an argument over which ones count.
After the call, send the draft and ask the champion to reply with her edits, even if she changes nothing. Her reply becomes the reference point for every check-in and for the final readout. Without it, the criteria tend to shift toward whatever the pilot happened to produce.
Ask the buyer directly what result would make her say no. Many AEs skip this question because it feels like inviting rejection. Yet her answer tells the AE which risk to watch from the first week. A buyer who can describe a failed pilot in one sentence has usually pictured the decision meeting already, which makes her a far more reliable champion.
Every proof of concept needs one person on the buyer's side who will say yes or no on a set date. Usually that person is the champion's boss or the budget holder. The AE should learn that name before the pilot starts, because the readout is too late to change anything. If the champion cannot name anyone, the account executive is probably selling to someone who cannot buy.
Steering committees look good on a kickoff slide, but they rarely meet after the first week. Five busy people from different teams will not find a shared hour every Friday. On top of that, nobody on the committee feels personally responsible for the outcome. Replace the committee with one decision owner and a 30-minute readout, then invite the others to that single meeting.
Book the readout during kickoff, while everyone still pays attention, and send the invite to the decision owner yourself. Once it sits on her calendar, canceling it takes a deliberate step from someone on her side. Add the same date to the plan both sides share, as our guide to the mutual action plan describes.
The worst way to lose a pilot is to win it and then surprise the buyer with the price. After four weeks of confirming that the product works, the buyer learns the rollout cost. Then procurement starts a process that nobody planned for, and the champion's energy drains away. By the time the contract is ready, the decision owner has moved on to other priorities.
Before kickoff, the AE should agree on these points and add them to the same document as the criteria:
Some AEs worry that an early price conversation will scare the buyer off. If it does, the buyer was never going to pay that price anyway. Both sides are better off learning that on a discovery call than after four weeks of setup, training sessions, and check-ins. The champion usually wants the number early anyway, since her finance partner will ask for it in the first budget conversation.
The pilot users who log in twice are rarely lazy. Usually, the champion picked them because they were available or senior, and the product does nothing for their week. A regional director who never builds the Monday spreadsheet has no reason to open a tool that replaces it.
Ask the champion to choose users who feel the problem every week, even if they are junior. She should also tell each user what the pilot is for and when it ends. That way the invitation comes from someone inside their own company, and users take an internal request more seriously than a vendor's email.
Watch usage from the first few days, and raise a quiet week with the champion by the end of week two. By week three, low usage has usually decided the outcome already. If nobody uses the product after a direct conversation, end the pilot early and ask what got in the way.
A weekly check-in should take 20 minutes and follow the same short agenda every time. Left alone, most check-ins drift into product demos or feature requests. The AE has to steer each one back to the written criteria, in this order:
One user describing a real moment tells the AE more than any usage dashboard. When a sales manager says she prepped Tuesday's one-on-ones from the new view, that sentence usually ends up on the champion's readout page. If users describe the product vaguely or change the subject, treat it as an early warning, even when the champion sounds happy.
Frontline managers can listen to recorded check-ins for their AEs' open pilots. They should listen for the drift that shows up on any stalled deal, where the AE stops asking about dates and starts fielding feature requests. An AE who has not mentioned the readout date by week three usually comes back with an extension request.
The two pilots in this table could use the same product for the same four weeks. What differs is what the AE and the buyer agreed on before the first login.
| Part of the pilot | Drifting pilot | Decision pilot |
|---|---|---|
| Success criteria | Discussed once, never written | Drafted by the AE, confirmed by email |
| Decision owner | A steering committee | One named person with budget |
| End date | "About a month" | Readout booked at kickoff |
| Pilot users | Whoever was available | People who feel the problem weekly |
| Pricing | Discussed after the pilot | Agreed before kickoff |
| Check-ins | Product demos and feature requests | Criteria, user stories, blockers, date |
| Typical ending | "Let's extend it two more weeks" | A yes, a no, or a stated reason |
Open the readout meeting with the criteria the buyer confirmed in writing, then go through the results one by one. Let the champion present, since the decision owner trusts her more than any vendor. The AE helps her prepare the page the week before, and during the meeting he stays quiet unless someone asks him something.
On a yes, the contract draft and rollout date should already exist, because the AE agreed on them before kickoff. If the answer is no, he asks which criterion failed and what would have changed the outcome, then logs the answer in the CRM that day. A clear no with a reason tells product and sales leadership which gap cost the deal.
Sometimes the buyer still asks for an extension at the readout. Agree only if the extension adds a named criterion and a new readout date on the decision owner's calendar. Sales leaders should treat a clean no as an acceptable pilot outcome in pipeline reviews. Otherwise AEs learn that "in pilot" looks better on the pipeline report than "closed lost," and they keep granting extensions.
Most of what decides a pilot happens on calls, from the first discovery call to the final check-in. A conversation intelligence platform keeps those calls searchable, so the criteria do not depend on the AE's notes. Rafiki AI transcribes calls in more than 60 languages, so a pilot with users in regional offices still leaves a searchable record.
Before drafting the criteria, the AE can use Gen AI Search to find where the buyer described the problem. After each check-in, Smart Call Summary summarizes the conversation. Smart Follow Up then drafts the recap email, which the AE edits and sends to the champion. Rafiki AI also maps which stakeholders joined each call, so the AE can see whether the decision owner has shown up since kickoff.
Smart Call Scoring scores every call against any methodology, including MEDDIC, or against custom criteria. A manager can add pilot items to the scorecard, such as whether the AE confirmed the readout date. Smart CRM Sync fills in methodology fields and custom CRM fields from the calls. For pilots, that could include a custom field for the decision owner.
Blocker detection and sentiment analysis help the AE spot a check-in where a user raised an obstacle or sounded doubtful. Across the whole team, a RevOps lead can use Gen AI Reports to see which blockers came up on this year's pilot calls. RevOps leaders can then share those patterns with AEs setting up next quarter's evaluations.
This week, list every proof of concept your team has running, including the ones already extended. For each pilot, check three things: written criteria, a named decision owner, and a readout on that person's calendar. Expect at least one of the extended pilots to be missing all three.
For every gap, the AE drafts the missing piece and sends it to the champion before the next check-in. Any pilot still lacking a readout date on October 30 gets a direct conversation about whether the evaluation is real. Plenty of buyers lock next year's budget late in the fall. A pilot that ends in a clear yes before Thanksgiving stands a far better chance of making the 2027 plan.
The criteria draft for your next pilot should start from the call where the buyer first described the problem. Rafiki AI's conversation intelligence keeps that call searchable, and plans start at $19 per seat per month. Use the free trial to look up that call for one open pilot before its next check-in. The other option is to book a demo with our team before you plan your next evaluation.
A proof of concept usually tests whether a product can solve a specific problem, often with a small technical group. By comparison, a pilot puts real users on real work for a set period. In B2B software sales, the two terms overlap heavily, and both should end with written results and a decision.
Set the length to match the criteria, since some results take longer to observe than others. For most software evaluations, a few weeks is enough to see whether users adopt the product. Longer pilots tend to drift, so book the readout date before kickoff.
A paid pilot tends to get more attention from the buyer, because someone had to approve the spend. Free pilots can work when both sides agree in writing on the criteria, the decision owner, and the readout date. The fee matters less than whether the buyer committed to a decision on a specific day.
Ask the buyer which criterion failed and what would have changed the result, then record the answer in the CRM. Share the reason with product and sales leadership, since patterns across failed pilots often point to fixable gaps. If the buyer wants to try again later, agree on new criteria and a new date first.
