How QuantHub Turned $20K in Ad Spend into $842K in Qualified Pipeline at a 38:1 Return

Broken tracking, no MQL or SQL definitions, and spam-heavy lead flow. We rebuilt QuantHub's entire demand generation infrastructure and handed their sales team a pipeline machine, not a list of non-ICP leads.

The Problem

QuantHub had a course catalogue worth selling. It had no system to sell it at scale.

QuantHub sells AI literacy and data fluency curriculum to universities, community colleges, and corporate training teams across the US. Their course catalog spans AI Foundations, Marketing in the Age of AI, AI in Accounting, and Applied Data Science, all built to drop into existing LMS environments in a single semester. The product was strong. The sales team was capable. But the demand generation infrastructure underneath it all was fractured.

The Google Ads and LinkedIn campaigns that were already running had no documented account structure, no conversion tracking, and no exclusion lists. The campaigns were live but flying blind. Form submissions were coming in, but a significant share were students and job seekers, not deans, directors, or program heads. Marketing had no MQL or SQL definition, no CRM lifecycle logic, and no way to tell leadership which spend was actually producing revenue.

Our Goal

Rebuild QuantHub's demand generation infrastructure from the ground up: clean attribution, qualified decision-maker targeting, and a multi-channel pipeline engine that connects ad spend directly to closed revenue.

Challenges

Four structural gaps between QuantHub's current state and a predictable revenue pipeline

What We Did

We didn't just fix their ads. We built a revenue-attributed demand generation system.

ads.expert entered as a full-stack performance partner, not a campaign manager. Before a single ad was optimized, we audited every layer of the funnel: tracking architecture, CRM data hygiene, audience logic, and conversion infrastructure. What came next was methodical, not reactive.

01

Conversion Architecture and HubSpot Alignment

Rebuilt Google Ads conversion tracking from scratch: goal-level attribution, value-based bidding signals, and cross-channel UTM taxonomy. Inside HubSpot, we defined MQL thresholds, mapped lifecycle stages, and built lead routing workflows so every inbound lead was scored, staged, and routed before it hit a sales rep's inbox.

02

ICP Audience Build-Out and Exclusion Infrastructure

Defined detailed ICP profiles for three buyer segments: higher-ed decision-makers (deans, department chairs, program directors), accounting faculty, and enterprise L&D leads. Built layered audience exclusions including job title negatives, student cohort suppression lists, and HubSpot-synced suppression audiences, cutting spam submission rate from high double digits to <2%.

03

Google Ads Full-Funnel Campaign Architecture

Launched and iterated a complete campaign structure: intent-based Search campaigns, PMAX for brand visibility and demand capture, and remarketing Display campaigns for site visitors and HubSpot lifecycle segments. Weekly performance reviews tied directly to pipeline output, not just CTR.

04

LinkedIn Outbound and ABM Sequences via Lemlist and Make

Built and launched multi-cohort Lemlist sequences targeting accounting professors, AACSB conference attendees, and higher-ed program directors. Prospect lists were enriched and qualified via Clay before entering sequences. Reply handling and follow-up branching were automated via Make, giving QuantHub a scalable outbound motion that required no additional headcount.

05

Multi-Channel Retargeting and Lifecycle Email Flows

Built remarketing audiences on Google and LinkedIn using site visitor behavior and HubSpot lifecycle stage, then activated them with targeted ad sequences. Designed HubSpot email workflows for mid-funnel lead nurture: stage-triggered sequences for higher-ed MQLs, eBook download follow-ups, and playbook leads, keeping warm prospects engaged without manual sales intervention.

06

Sales Intelligence and Pipeline Operations

Generated enriched target persona lists and prioritized lead queues for the sales team, segmented by buyer type, engagement signal, and funnel stage. Built instructor and accounting professor databases to support outreach campaigns, and delivered weekly closed-won/closed-lost deal analysis to identify which campaigns and channels were producing revenue versus pipeline noise.
