How Infinium Associates sales team saw a 45% increase in email response rate

• Client: Infinium Associates
• Industry: HR Consultant (Staffing and Recruiting)

Infinium Associates is a top-tier HR consulting firm known for accelerating growth, improving operational efficiency, and helping clients navigate complex market dynamics. To stay ahead, Seraj needed a way to reach the right executives at the right moment — without spending his week hunting for lists and writing emails.

The Challenge

Infinium's outbound looked like most B2B outbound: static lead lists pulled from Apollo or Sales Nav, generic personalization ("I saw you're the Head of…"), and manual research that ate hours per prospect. By the time a "personalized" email went out, the trigger that would have made it relevant — a new hire, a funding round, a stalled hiring plan — was often already gone.

Seraj needed three things a traditional stack couldn't give him in one place:

1. Leads surfaced by real-time buying signals, not static filters.
2. Verified email and phone on every contact, ready to action.
3. Research and sequences written against the actual reason to reach out — not the prospect's job title.

The Solution: Coolie's Agent Stack

Infinium deployed Coolie, an end-to-end AI GTM platform built around four agents that run the outbound loop from signal to sequence.

1. Prospect Agent — signals, not lists

Instead of uploading a lead list, Seraj configured Coolie to watch 23 real-time buying signals across his ICP: HR leaders being hired, companies posting talent-strategy roles, restructuring announcements, funding events, and leadership changes at target accounts. Every morning, Coolie surfaced a fresh set of accounts that had just done something worth reaching out about.

2. Enrichment Agent — contact data on autopilot

Every surfaced lead came enriched with verified work email and direct phone number, plus firmographic and ICP-fit scoring. No exporting to a separate waterfall tool, no chasing bounces.

3. Research Agent — 300+ insights, one tension

This is where Coolie separates from the "AI personalization" pack. For each lead, the Research Agent pulls 300+ contextual insights and runs 3rd-Level Research: Event → Strategic Intent → Tension. It doesn't just note that a company hired a new CHRO — it works out why, what that CHRO is under pressure to fix in their first 90 days, and where Infinium's offer maps to that pressure.

4. Sequence Agent — multi-channel, tension-led

The Sequence Agent then wrote a 5-step multi-channel cadence (email, LinkedIn, WhatsApp, and call scripts) referencing the specific tension the Research Agent surfaced. Not "I saw you're hiring" — but "most CHROs brought in after a Series B restructure spend month two firefighting comp bands…"

Implementation

• Concierge onboarding: Coolie's research team encoded Infinium's ICP, offer, proof points, and target signals into the platform, so Seraj didn't have to configure it himself.
• Signal tuning: Together they locked the signals that mapped most cleanly to HR consulting engagements.
• Channel setup: Email infrastructure and LinkedIn cadence connected once, then left to run.

From there, Seraj's job shifted from "build the list and write the emails" to "review the leads Coolie surfaced this morning and take the meetings."

Results

• Time on prospecting and copywriting dropped by 70%, freeing Seraj to focus on discovery calls and client delivery.
• Reply rates lifted 45% — because the message referenced a real, current tension, not a generic hook.
• Pipeline coverage scaled without adding SDR headcount, since the signal-driven model surfaces new accounts every day rather than exhausting a static list.
• 2.5× ROI on outbound spend within the first cycle.

Client Testimonial

"I used to spend my mornings hunting for leads and rewriting the same email. With Coolie, I open the platform and the leads are already there — with the reason to reach out, the contact info, and the sequence written. It's the difference between outbound being a job and outbound being a system."
