Features

Every step of outbound, automated.

An agent for every step of the pipeline. Composable, observable, and built for scale.

Company enrichment

Web-search agents pull real-time signals: industry, size, tech stack, recent moves. No stale Apollo exports.

ICP scoring

Weighted fit across role, vertical, geography, and pain signals. A/B/C/D tiers that route to the right sequence.

Personalised email writer

One opener per lead, grounded in enrichment data. Anti-fabrication rules prevent made-up stats.

QA review agent

A second AI reviews every draft against a 14-point checklist. Rewrites or rejects before your team sees it.

SmartLead + HubSpot delivery

Approved sequences auto-push to SmartLead campaigns; contacts sync to HubSpot with engagement timelines.

Bring your own keys

AES-256-GCM encrypted per-org. Anthropic, OpenAI, Google, DeepSeek, SmartLead, HubSpot — your credentials only.

The loop

Six AI agents, one pipeline.

Every lead flows through the same deterministic path — observable at every step, resumable on failure.

04

ICP Score

AI

Weighted fit scoring across role, vertical, geography, and pain signals. A/B/C/D tiers route to the right sequence.

Generates your follow-up steps from the customisable sequence template — 1 email or 20, each with its own framework.
