Customer story – Scalestack

How Scalestack uses Ocean to scale targeted outreach for their customers

Scalestack integrated Ocean's lookalike API to expand their customers' prospect pools automatically — then layers on AI prioritisation so revenue teams always know who to reach out to first.

The company

Scalestack

Scalestack is an AI-powered data orchestration platform that helps revenue and growth teams identify high-value prospects, prioritise leads, and eliminate inefficiencies with intelligent workflows and real-time data insights.

Their Universal API enriches prospect profiles on demand — so their customers always have the right data at the right moment. Partnering with Ocean adds the crucial first step: finding the right accounts to enrich in the first place.

The challenge

Finding the right leads at scale, not just a lot of them

For revenue teams, the challenge isn't just finding leads — it's finding the right ones at scale. Scalestack's customers were sitting on outdated prospect lists, wasting time on low-fit accounts, and missing opportunities that were right in front of them.

To deliver real value, Scalestack needed a way to not just prioritise existing lists but to continuously expand them with high-quality lookalike accounts that actually fit their customers' ICP.

The solution

Ocean expands the funnel — Scalestack prioritises it

Scalestack partnered with Ocean to build a complete top-of-funnel workflow. Ocean identifies lookalike accounts that match a customer's ICP — expanding the prospect pool — while Scalestack's AI then prioritises and enriches those accounts so teams know exactly who to reach out to first.

Lookalike account discovery — Ocean analyses CRM and customer data to find companies that match the ICP — expanding the total addressable prospect pool

Event-triggered outreach — Ocean surfaces lookalikes based on buying signals — like website visitor activity — so outreach is timely, not just targeted

AI prioritisation on top — Scalestack's models rank Ocean's accounts by fit and intent, so reps always start with their highest-probability leads

Rigorous data quality — Scalestack's quality control processes ensure every account from Ocean meets their standards before it enters the workflow

"Ocean.io expands the sea into an ocean, and Scalestack is great at fishing in this vast ocean."

The result

A complete top-of-funnel pipeline for their customers

The Scalestack–Ocean integration gives revenue teams the full package: a continuously expanding, high-quality prospect pool — prioritised and enriched so every rep knows their next best move.

Expanded prospect pools for every customer — Ocean surfaces lookalike accounts that customers would never have found through their existing processes

Timely, targeted outreach — Event triggers mean reps reach out when accounts are actually in-market — not just when the list was last refreshed

A seamless integration experience — The partnership is built on close collaboration between both teams — ensuring the data flowing through the integration meets Scalestack's quality bar

"The partnership is a testament to both teams. Together, we're redefining how revenue teams identify and engage with their next best customers."
