The stack we build and run GTM on.

SmartLead

Outreach & Sending

SmartLead is where client campaigns actually send. We run it at the account root, each client as a white-label sub-account under clients.leadlinepartners.co, so their prospects never see us. Sequences, inbox rotation, warmup, reply routing. We drive it from the command line day to day and fall back to the API when something custom is needed. Deliverability lives or dies here, so it gets watched closely: bounce rates, open patterns across days, reply sentiment over reply count.

Clay

Data & Enrichment

Clay is the enrichment layer. We build wide target lists, then run them through waterfalls that stack providers so coverage stays high and cost stays reasonable, with FullEnrich handling the email step. Qualification happens here too. Claude scores and personalizes on pre-filtered subsets of a few hundred rows, never a raw list of thousands. Qualified prospects post back and move to SmartLead. We're on the legacy Explorer plan, which still beats the newer two-currency pricing at our volume.

Attio is the system of record for LLP's own pipeline, not our clients'. Campaign signals from SmartLead flow in automatically: who replied, what stage a deal sits at, which lead maps to which company. We keep it strictly isolated. Only LLP's root-level prospecting ever touches this workspace, never a client's data. Clients who want their own CRM get their own, on their keys. Attio's flexible data model is why it fits a GTM engineering workflow better than a rigid legacy CRM.

Trellis

CRM & Pipeline Ops

Trellis is ours. We built it because the off-the-shelf sales ops tools didn't fit how GTM engineering actually runs. It handles call lists and dialer attribution, a master inbox that pulls conversations together, disposition tracking, and client billing reconciliation. Running our own product means we ship the exact workflow we need instead of bending to someone else's. It also keeps us honest about what a modern GTM system should feel like.

Claude Code

AI & Intelligence

Claude Code is the core of how we operate. It's the reasoning layer across the whole stack: scoring prospects, personalizing at the row level, running deep account research, drafting outreach, and building the internal tools that connect Clay, SmartLead, and the rest. When a campaign needs custom logic, an enrichment step, or a one-off scraper, this is where it gets written. Most of what makes our 'more with less' approach work runs through here.
