Outreach that compounds, not burns.
Prospect Spire is a SaaS platform for outbound managers running multi-segment outreach. Smarter sequencing, A/B prompts, deliverability lift, intent-aware drops, and an automatic next-best-action for every prospect on the climb.
Three modules. One compounding curve.
Outbound stops being a quota grind when each lever lifts the next. Prospect Spire is built around three modules that stack into a curve, not a treadmill.
Sequence intelligence
A/B prompts, branch logic by reply class, and channel-aware spacing. The platform learns which opener works for which segment and rewrites the next step before you have to.
- A/B prompts on subject, opener, and CTA
- Branch by reply class (interested, not now, wrong person)
- Channel-aware step spacing per segment
Deliverability lift
Inbox placement is a moat, not a checkbox. Domain rotation, warmup, sender-score reads, and bounce monitoring keep mailbox reputation climbing while your volume scales.
- Multi-domain rotation with per-mailbox caps
- Warmup engine and SPF, DKIM, DMARC health
- Bounce, spam, and seed-test loops
Intent-aware drops
Trigger events get the right cadence at the right moment. New hires, funding rounds, role changes, and product-page visits each route into a tailored drop with the next-best-action queued.
- Signal library: hiring, funding, tech-stack moves
- Auto next-best-action per stalled prospect
- Drop calendars tuned to segment timezones
How the curve compounds.
Four loops run in the background so every cohort starts further up the tower than the one before it.
Map
Segment workspace, ICP filters, and signal subscriptions. The platform builds a tower view per segment with stage-by-stage benchmarks.
Run
Sequences fire across email, LinkedIn, and phone. A/B prompts cycle. Deliverability guardrails throttle sends per mailbox in real time.
Read
Replies, opens, and intent signals stream into one stage view. Stalled prospects get tagged with a next-best-action suggestion.
Lift
Winning openers, channels, and drops promote into the segment default. Losing ones retire. The next cohort starts on the new baseline.

The curve, in two operator's hands.
Codenamed outreach teams who let the platform compound segment by segment. Numbers are cohort-over-cohort, not promised quotas.
Three segments, one compounding tower
Before: One mega-sequence for every persona. Reply rate flat for three cohorts. Mailbox reputation drifting from a slow bounce climb. Manager spending a day a week reading inboxes.
With Prospect Spire: Segments split into platform engineers, eng managers, and VPs. A/B prompts ran for two cohorts. Deliverability lift module rotated three new domains and rebuilt warmup. Next-best-action queue handled stage-03 stallers.
Intent-routing a regulated segment
Before: Compliance officers ignored cold sequences that looked templated. Regulated buyers refused calendar holds without context. Manager held back on volume to protect the brand.
With Prospect Spire: Intent-aware drops routed funding-round and audit-cycle signals into custom cadences. Approval gates wrapped the regulated segment. Prompt library kept legal-safe phrasing reusable.
