The database is not your market.

When you buy 1,000 records from a data supplier, only 65 prospects will pick up the phone. Most teams spend a month to find them. We find them first.

Illustrative UK campaign.

Five stages. One output.

Every prospect goes through five stages before they reach an SDR.

1
Stage one · Source

We start wider than anyone else.

Only a small share of any market makes it through, so we build from the top 20 global B2B databases and your own signals. Accounts are matched with ideal customer personas (prospects) to form segments, and each segment gets its own list and so you can create a pitch to each prospect segment.

2
Stage two · Qualify

Half of every list is wrong. We remove it.

50%removed, on average

Data providers are paid by the credit, so they over-deliver. Our AI checks every record against your ICP and removes the wrong roles, sizes, markets and companies.

3
Stage three · Enrich

No direct line, no dial.

~70% UK · ~40% USAmobile and cell phone enrichment

Switchboards waste calls. Only prospects with a direct, B2B-compliant mobile and cell phone numbers go forward.

4
Stage four · Score

We find out who picks up, and when.

Pickup propensity: the likelihood a prospect picks up, scored by the Sentrama Engine before a call so only the most likely are dialled.

We dial your whole market so your SDR doesn’t have to.
5
Stage five · Deliver

Result: a Sentrama lead.

A named person in your ICP who we know picks up, called at the time they pick up. This is a Sentrama Lead and the only thing you pay for.

They are 3.5 times more likely to turn into an opportunity.

Why TAM size matters

Only a small % of any total addressable market (TAM) will ever pick up. We only call the small share who pick up, so a small TAM will run dry fast.

The funnel

Sentrama vs the standard SDR.

An SDR buys a list and dials all of it. Half the list is bad data, and they only find that out by dialling it. The rest they dial again and again, hoping someone picks up. We start with the same list. AI qualification removes the bad half before a phone rings. Our engine, built on 5,000,000+ dials, finds the prospects in your ICP who pick up. Both routes end with the same prospects on the phone. With an SDR you pay for every dial. With us you pay only for the prospects who pick up.

Illustrative campaign worked back from 100 leads. Everyone else is shown dialling each number once at 100 dials a day; real teams redial, which only adds to the waste. Published dials a day: Bridge Group 44 (56 for phone-centric teams), Gong 40, Tenbound 80 to 100. Pickup rates from 5,000,000+ dials on the Sentrama platform.

Your Pitch and Why it matters

You get three sentences. We make sure they count.

The average pitch window is 30 to 40 seconds. Your pitch decides whether it lands. The engine makes sure it goes to the right prospect at the right time.

If the pitch is the half that’s broken, that’s what Campaign Optimisation fixes.

The engine learns

Every 100 leads, it gets sharper.

Every call is transcribed. After every 100 leads we remove who’s saying no, find more of who’s saying yes, and give the insights you need to improve the pitch.

Frequently asked questions.

What is pickup propensity?
If someone picks up at a certain time, they’ll pick up at that time again. We call each prospect at nine different times to find out when that is. Prospects who pick up are 3.5x more likely to turn into an opportunity due to their nature.
Why not just call everyone?
Of the numbers worth dialling, only about 19% pick up in the UK. The rest of the calls go nowhere. We absorb those calls so our SDRs only speak to prospects who pick up.
Do I pay for scoring dials?
No. You only pay for leads.
What if my prospects are senior?
Pickup rates for senior prospects can drop to single digits. We start with a bigger account pool so enough prospects who pick up come out the other end.
How long before we’re live?
The first pass takes about five business days.

Your market already contains the prospects who pick up.

We’ll find them.

All figures are first-party Sentrama platform data, drawn from 5,000,000+ dials, and over 600,000 pitches delivered across 120 client organisations since February 2025. Rates vary by market, seniority and geography.
