The Challenge

Cold outbound at scale needs personalisation, but lead sourcing was fragmented across 4+ platforms and outreach was templated and generic — so reply rates stayed low and pipeline was unpredictable.

The Approach

We built an autonomous pipeline: prospects are sourced across the open web into one place, enriched in real time, then handed to an LLM that drafts a personalised message per prospect. Durable workflow orchestration runs the multi-step sequences, and analytics track reply rates end to end.

How we built it

  1. 01

    Sourced prospects across the web

    Pulls ideal-fit prospects from multiple sources into a single pipeline instead of 4+ disconnected tools.

  2. 02

    Enriched in real time

    Each lead is enriched on the fly so outreach can be genuinely personalised, not templated.

  3. 03

    Drafted personalised outreach

    OpenAI drafts a per-prospect message; Temporal orchestrates the multi-step sequences durably and reliably.

  4. 04

    Scaled with deliverability in mind

    Engineered for 97% deliverability, with reply-rate analytics stored in ClickHouse for fast reporting.
