Lift every cadence higher.
Cadence Spire is a cadence performance lifter. Step by step, it optimizes the cadences you already run. A/B tested copy, automatic prompt tuning, deliverability lift, and reply-rate climb, surfaced where you can see the gain.
Four levers. Compounding climb.
Every cadence has slack in it. Cadence Spire finds the slack and pulls it, step by step, until the whole sequence is lifting reply rates and deliverability together.
A/B Testing, Always On
Every step in every sequence runs two variants by default. Spire promotes the winner, retires the loser, and queues the next challenger.
Automatic Prompt Tuning
Subject lines, openers, and CTAs are tuned against reply outcomes. Spire learns which phrasings actually move your buyer, not generic best practices.
Deliverability Lift
Domain health, warm pool rotation, spam-trigger scrubbing, bounce throttling. The plumbing keeps your sends in primary, not promotions.
Signal Triggers
Role changes, funding events, hiring spikes. Spire pushes the right contacts into the right cadence the moment a trigger fires.
Every cadence step, visible and tunable.
Cadence Spire opens up the black box. Each step in your sequence is a row you can see, A/B test, and tune. The platform suggests the next lift, runs it, and shows you the gain in plain numbers.

Three modules. One climb.
Cadence Spire ships as three connected modules. Use one, use all three. The lift compounds when they run together.
Spire Lift
The A/B engine and prompt-tuning loop. Runs continuously against every step in every active sequence.
- Variant engine with auto-promotion
- Prompt tuning against reply outcomes
- Step ledger with per-step attribution
- Cohort guardrails on every test
Spire Inbox
Deliverability lift built as a first-class module. Spire handles the plumbing so the lift work is not wasted on filtered sends.
- Domain health with daily score
- Warm pool rotation, bounce throttling
- Spam-trigger linting on every variant
- Primary-tab placement tracking
Spire Signals
Event-driven enrollment. Spire watches for triggers and routes the right contact into the right cadence the moment a signal fires.
- Role and hire change feeds
- Funding and growth event stream
- Trigger-to-cadence auto-routing
- Cooldown rules per contact and account
Two cadences. Two real climbs.
What it looks like when an existing cadence runs on Cadence Spire for a full lift cycle. Codenames swapped, metrics intact.
Project Halyard
Before: A six-step cadence to engineering leaders was stuck at 3.1% reply, with Step 3 doing most of the damage. Heavy bounce rates in the warm pool kept dragging deliverability down.
On Cadence Spire: Spire Lift ran 14 variant cycles on Steps 2 to 5. Spire Inbox rotated the warm pool and quarantined a flagged domain. Spire Signals re-enrolled VP Eng role-changes into a tighter path.
Project Marlin
Before: A CFO-targeted cadence pulled steady opens but soft replies. Step 4 was an unlinted CTA tripping spam filters. Signal enrollment was manual and lagging by days.
On Cadence Spire: Prompt tuning rewrote the Step 4 CTA against reply outcomes. Spire Inbox flagged the trigger phrases. Spire Signals auto-enrolled new CFO hires the day the role change landed.
