The challenge

Where it started

Outbound tools get sales teams blacklisted. The goal was a CRM and sequence engine where the safety layer, not the sales rep, decides when sending stops — plus an AI assistant that acts, not just chats.

What we built

The build

  • Sequence Intelligence: nine layers (timing, deliverability, personalisation, intent, conversation, fatigue, conflict resolution, outcome, governance) under a Guardrail
  • Sequence Risk Score with healthy/elevated/risky/dangerous bands; dispatcher enforces min(daily cap, guardrail cap)
  • Vera upgraded from command bar to agent runtime: plan → confirm → execute → independent verifier
  • Multi-mailbox rotation, recipient-local send windows, advisory-lock dispatcher with SKIP LOCKED
  • Razorpay billing with webhook-replay and signature fixes; partner program and portal
  • Hardening: request-log redaction, SSRF-guarded fetch, CSV formula-injection guard, hashed tokens
Outcome
