Sales-call review and prospect research
Last updated: November 2026
Tim Kilroy offers four AI tools for agency sales: Call Lab Instant, Call Lab, Call Lab Pro, and Discovery Lab.
The Call Lab tools review sales calls and give coaching feedback; Discovery Lab researches a prospect before the call. On DemandOS for Agencies they matter for one reason: a sales process only improves when someone reviews the calls, and the founder rarely has time to review every one.
Start with Call Lab Instant for quick feedback on how you deliver a pitch; it needs no account and no transcript. Use Call Lab when you have a transcript and want a full coaching breakdown.
Use Call Lab Pro to score calls against methods such as SPIN, Challenger, MEDDIC, and Sandler and track improvement over time. Use Discovery Lab before the call, to research the prospect.
A sales process only works if someone checks whether the team is running it. In most agencies, that someone is the founder, which recreates the founder dependence the process was meant to remove.
Call review tools give every rep feedback on every call: what worked, what did not, key moments, objections, and the talk-to-listen ratio. The founder can then coach the patterns instead of sitting in on each conversation.
Tim Kilroy's discovery playbook says most agencies blow the call before it starts, because they do not prepare. Discovery Lab is built for that step.
It produces a brief with a company overview, recent news, conversation starters, and smart questions to ask, in about 60 seconds. The goal is to arrive thinking about the prospect's business, not reading their homepage for the first time.
No call review tool decides who your agency serves or what it should charge. If calls keep stalling on price, the root cause is usually positioning, not delivery.
Use the tools to inform a sales system and a coaching conversation. They are not a substitute for the first change Tim Kilroy asks owners to make: a clear niche and a real sales process.
The tools sit inside what Tim Kilroy calls TriOS: SalesOS, DemandOS, and GrowthOS. Call Lab and Discovery Lab belong to the sales side.
If you are unsure where to start, his site offers a two-minute WTF Assessment that points to the area where the agency is most stuck and which tools to try first.

Not entirely. Call review tools catch patterns a founder misses, such as talk-to-listen ratio, objections, and missed next steps, on every call. A coach helps decide what to change in positioning, offer, and process. Tim Kilroy offers both, reflecting the view that tools inform a sales system rather than replace one.
Leave knowing what is broken in the prospect's business, how big the problem actually is, what they have already tried, how they make decisions, and whether you can genuinely help. If you leave without those five things, Tim Kilroy's playbook says you did not do discovery, no matter how good the conversation felt.
