Your Data-Driven Acquisition & Growth Partner for B2B SaaS
Founded in 2010, Surge45 partners with B2B SaaS companies at every growth stage, from seed-stage startups scaling to Series A, through to public enterprises optimizing unit economics. We've helped 200+ companies influence over $2.5B in ARR through data-backed customer acquisition and expansion strategies.
Our Story
Surge45 was founded with a clear mission: to be the data-driven growth partner that understands the unique economics of B2B SaaS. While generalist agencies focus on leads, we optimize for the metrics that matter to your board, including CAC payback, win rates, expansion revenue, and net revenue retention.
Today, we're a team of 50+ specialists with deep expertise across the SaaS buying journey. We understand your buyer personas, from hands-on developers to C-suite decision-makers, and the complex, multi-stakeholder buying processes that define enterprise SaaS.
What sets us apart is our obsession with data. Every strategy we build is grounded in analytics. We connect the dots between your CRM, product usage signals, intent data, and marketing performance to create a unified growth engine that turns insights into revenue.
How We Use Data to Drive Your Growth
We don't guess. We analyze, model, and optimize. Every decision we make is backed by real performance data from across your entire growth stack.
Our proprietary attribution models pinpoint the channels and campaigns delivering the lowest cost-per-acquisition, so we double down on what works.
We ingest data from your CRM, marketing automation, product analytics, and intent signals to build a 360-degree view of your pipeline.
By combining predictive lead scoring with real-time engagement data, we identify and accelerate the deals most likely to close.
Our data models start delivering actionable insights from week one, with full optimization cycles running within the first quarter.
The Surge45 Data Loop
