OUR MODEL
StackOne is a Google Ventures-backed Series A company building The Universal Integration Layer for Modern Products.
Our platform offers a single integration solution with two powerful interfaces: Unified APIs for SaaS products, and AI Agent Actions. With StackOne, teams can ship hundreds of integrations in days, not months.
But to sell a technical product to technical buyers, we needed precision in every outbound motion. Success depended on targeting accounts with high intent, relevance, and urgency at scale.
THE NEED
Before working with OrbitalX, our outbound efforts were stalling. We were relying on account and contact data that anyone else in our category could access. Manual sourcing helped improve quality, but it was slow, labour-intensive, and unsustainable for our lean team in London.
We knew outbound could be a growth lever, but only if we had a smarter way to prioritise accounts and personalise at scale.
THE SOLUTION
Having worked with OrbitalX’s founders before, I trusted they could help us stand out in a saturated space. Their team brought deep experience building proprietary data models for high-performing GTM teams. From day one, they understood what we needed and how to deliver it.
OrbitalX embedded directly into our team. Together, we built custom workflows that surfaced accounts and contacts aligned with our ICP, growth stage, and technical nuance. We even brought on dedicated analysts to support the model.
Week by week, we had a tighter, more accurate, and higher-performing outbound engine.
THE WIN
With bespoke, high-quality data powering our outreach, reply rates soared. We consistently saw outbound reply-to-meeting rates of up to 15% across key channels—results that were unthinkable with standard off-the-shelf data.
Because our messages were grounded in real signals and intent, we were no longer just reaching out. We were starting conversations that mattered.
