The meetings that you delivered have all been really high quality… I think that's always one of the fears when you work with a Agency and that you know meetings could be just booked just to hit a certain number but that definitely hasn't been the case

Frequently asked questions (FAQs).

The questions buyers ask us.

What exactly do you guarantee?
We guarantee defined commercial outcomes and qualified sales meetings with your ideal customers. Every meeting is quality-checked against our 14-step standard before it lands in your pipeline.
What counts as a qualified meeting?
A meeting counts when it passes our 14-step Sentrama Standard. The prospect matches your ICP and has a declared pain or reason to meet, and a specific time is agreed and accepted on the call. We confirm attendance before the meeting, and log every booking with full transparency in your pipeline.
How does your pricing work?
You pay per outcome and per qualified meeting. No retainer, and nothing for activity. The Algorithmic Cold Calling Platform is included, so you are not buying data or hours, you are paying for verified commercial progress. We price bespoke to your market and targets after a short scoping call.
How is this different from a traditional agency?
Traditional agencies sell activity on a retainer. We sell controlled results on results-based pricing, with full transparency through our platform and complete audit trails on every interaction.
What's the difference between Leads, Outcomes, and Meetings?
We operate across three levels of outbound maturity. Leads are verified ideal customers who pick up the phone, with a reason to call (validated roles, phone numbers and emails), which solves your data problem. Outcomes are real, human conversations with your ideal customer from our experienced SDRs, captured with an outcome, notes, objections and full transparency, which solves your SDR execution problem. Meetings are quality-controlled, ICP-aligned sales meetings booked directly into your calendar, which solves your pipeline problem. In simple terms: Leads fix your data. Outcomes fix your resource and execution. Meetings fix your pipeline.
Who is Sentrama a good fit for?
B2B companies with a defined ICP, a real product, real margin, and a sales motion that justifies senior outbound. If your buyers are senior and worth a human conversation, we fit. If you need cheap volume and scraped email lists, we are not the right agency.
Can we start small before committing fully?
Yes, and most clients do. We always offer a short-term paid proof of concept.
How do we get started?
Most clients start with a short Proof of Concept covering data, strategy and a minimum number of qualified meetings, then move into an ongoing outcomes package.
