Case studies

The engines we've built

The problem in each case, what we built, and what it produced. Every number here is attached to a client who put their name to it.

Billing and pricing infrastructure

GTM Engineering$30M raised, acquired by Adyen

Orb's CRM held 2,000 accounts and was going stale. They needed a far larger addressable market, account data that stayed current without anyone maintaining it, and qualification that did not depend on hiring.

What we built

TAM expanded from 2,000 to over 30,000 accounts using Clay lookalike search and enrichment
Automated CRM enrichment running at 7,000 objects a month, continuously refreshed
AI agents for account scoring and MQL qualification, replacing manual triage
Website visitor de-anonymisation, turning inbound intent into qualified records in real time
First-touch sequences built for the SDR and AE teams
Zapier migrated to n8n, for automation that holds up at volume

15x: TAM expansion, from 2,000 to 30,000+ accounts
7,000: CRM objects enriched every month
3: Meetings booked in a single day

“Alexis and his team have been great partners to our growth and I highly recommend working with them.”

Marketplace and go-to-market enablement

GTM EngineeringBacked by a $100M fund

Three acquisition channels running separately and by hand: events, AWS Marketplace inbound, and outbound. VeUP needed all three qualified, automated, and landing in one Salesforce motion.

What we built

An AI SDR pipeline connecting HeyReach, Smartlead, Clay, Gong, Salesforce and n8n end to end
Tiered AI replies: lower-priority responses answered autonomously, the top tier drafted for a human to approve
Event acquisition automated end to end in Luma, from creation through to RSVP flows
Website and AWS Marketplace inbound de-anonymised and routed into Salesforce automatically
Salesforce enriched across the full funnel, with Gong call intelligence populating opportunity fields

5,000: Companies qualified every week
3: Acquisition channels running automatically

“In just 5 weeks of working with the team, we've been that impressed by the setup, the quality, the onboarding, the results that we've now kicked off another 3 projects.”

Event technology

GTM Engineering$80M+ raised

Planned inherited a powerful but unused Clay setup from a previous agency. Email coverage was low, personalisation was missing, and the engine was not producing enterprise pipeline. We audited it, rebuilt it from the ground up, and put it to work.

What we built

A full audit of the previous agency's Clay setup, identifying the gaps in enrichment, ICP definition and sequencing
Around 150,000 inherited contacts re-enriched from scratch
Two parallel motions built: bottom-up across four ICPs, top-down across seven
16 email sequences, one per ICP per personalisation angle
200 mailboxes deployed, running 4,000 personalised emails a day
Over 23,000 leads activated through LinkedIn retargeting
OutboundSync deployed so every campaign action is visible in HubSpot

23: Enterprise-qualified leads in the first month
68%: More valid work emails, reaching 75% coverage
45%: LinkedIn connection acceptance rate
4,000: Personalised emails a day, across 200 mailboxes

“OneThousandPieces helped us at Planned turn Clay from a powerful tool into a fully functioning outbound engine. They combined smart GTM strategy with deep automation expertise to consistently generate enterprise qualified, high-intent leads for our sales team (23 in the first month). Highly recommended if you want to scale outbound without losing personalization.”

Retained executive search

GTM Engineering

Growth in executive search ran on founder relationships and manual outreach. ISG needed to reach senior executives at the moment they moved into a new C-suite role, at a volume nobody could work by hand.

What we built

LinkedIn and email outbound built from the ground up across HeyReach and Smartlead
Multiple LinkedIn sending personas running simultaneously across the ISG team
Signal campaigns on job postings, targeting newly placed CEOs, CFOs, COOs, CPOs, CIOs and heads of people
