Every booked call teaches the next message.
We measure the signal that triggered the outreach, the hook, subject line, tone, channel and send window, then the reply, the objection and the booking. The engine keeps what converts and drops what does not.
Four data layers, joined on one outcome.
Every message we send carries the signal that triggered it and the decisions that shaped it. When a call gets booked, we know exactly which combination produced it.
- 01Signal data
- Follows, event attendance, departures, new hires, funding and headcount movement, tech stack change, all timestamped.
- 02Campaign metadata
- Hook, subject line, word count, tone, personalization tokens, sequence step, channel, send hour and day.
- 03Response data
- Opens, replies, reply sentiment, objection type, and the exact language that moved a thread forward.
- 04Outcome data
- Slots offered, calls booked, attendance, no shows, and time from first signal to booked conversation.
The engine only keeps what books calls.
- Step 1
Detect
A signal fires on an account we are watching. It is stored with its source and timestamp.
- Step 2
Decide
The engine selects the hook, subject shape, tone, channel and send window with the best history for that signal and role.
- Step 3
Send
The message goes out on the channel that account is most likely to answer on.
- Step 4
Measure
Every open, reply, objection and booking is written back against the exact decisions that produced it.
- Step 5
Learn
Weights update. Weak signals and losing phrasing lose volume, winning combinations get more of it.
Not every signal is worth a message.
We rank signals by lift against our own baseline outreach. Relationship signals, a prospect following a target exec or a company page, outperform demographic filters by a wide margin.

A soft interest ask out performs a hard link ask.

Attrition alert
Departure window12 accounts flagged where a finance owner departed and a replacement has not been named.
Outreach is prioritized inside fourteen days of the departure signal, while the budget is still unowned.
The hook, the subject, the shape. All decided by data.

Channel performance
Email vs LinkedIn1,842 sent, 72% of volume
781 replies, 142 booked
716 sent, 28% of volume
319 replies, 53 booked
LinkedIn replies slightly higher, email drives far more booked volume. So the decision is per prospect, not per campaign.

Reply rate by tone- Casual28%41% of volume
- Warm26%22% of volume
- Direct23%27% of volume
- Formal9%10% of volume

A reply is not a booking. The engine learns the turn after it.
Best reply pattern

- Send asset only48%
Never send an asset without a dated call to action attached.
Best tone
Resolution rate- Empathetic55%

Solid default, empathetic phrasing wins on price pushback.
- Formal38%
Reserve for financial services and enterprise threads.

Loses credibility once an objection is raised.
Best next ask
Resolution rate- Direct ask53%
Pair the reframe with one specific dated slot.
- Social proof49%
Naming a comparable customer lifts resolution.
- Urgency47%
Urgency after an objection backfires, avoid it.
- Soft suggest40%
Too passive after an objection, switch to a dated ask.
Resolution by segment
Objection to booking- Professional services41%
Anchor on billable hour recovery instead of seat cost.
- Healthcare38%
Lead with privacy posture before any product claim.
- Financial services28%
Address compliance up front, unaddressed risk stalls threads.
- SaaS and software25%
Technical proof points resolve objections fastest.
- Manufacturing18%
Longer cycles, expect two objection turns before a booking.
Use the intelligence with your team, or let ours run the outreach.
Either way, the same engine decides the signal, the hook, the subject, the channel and the timing, and every outcome is written back into it.
