Who Is Nexus Cloud?

Nexus Cloud is a B2B SaaS company building cloud infrastructure management tools for mid-market tech teams. Having raised a Seed round, they were approaching their Series A and needed to demonstrate strong, repeatable pipeline generation to investors — fast.

Their product was excellent. Their GTM was non-existent. Every lead they'd ever generated came through inbound content and founder network introductions. They had zero outbound infrastructure, no SDR, and no system for proactively generating meetings at scale.

The Problem

When Nexus Cloud came to us, they were 60 days away from starting serious Series A conversations with investors. Pipeline was the biggest gap — and they had no way to fill it fast enough through inbound alone.

01

Zero Outbound Infrastructure

No sending domains, no warmed inboxes, no cold email tooling. Starting cold email campaigns from a primary business domain would guarantee spam placement and domain damage. Everything needed to be built from scratch.

02

No Repeatable Pipeline System

Their founder was manually reaching out to contacts individually via LinkedIn with no tracking, no follow-up system, and no scalable process. This was eating 8–10 hours of founder time per week with minimal output.

03

Vague ICP Definition

They knew they targeted "tech companies" but hadn't defined buying triggers, company size ranges, tech stack signals, or which decision-makers to prioritize. This made targeting and messaging generic and ineffective.

04

No Messaging Framework

Their existing outreach mirrored their marketing copy — feature-heavy, not pain-focused. Nothing addressed the specific frustrations of engineering managers or CTOs who'd relate to their product's core value.

The Plan We Built

We identified two core ICP segments: engineering managers at Series B–C SaaS companies (50–300 employees) using AWS or GCP who were actively hiring DevOps — a strong buying signal for cloud tooling. Secondary segment was CTOs at bootstrapped SaaS companies with 20–80 engineers where infrastructure chaos was a known pain point.

Our approach was infrastructure-first. Before writing a single word of copy, we set up a parallel sending infrastructure completely separate from their primary domain. We then built intent-based prospect lists using hiring signals on LinkedIn and technographic data, ensuring every prospect had a credible reason to care about cloud infrastructure management.

Messaging was built around three pain angles: unexpected AWS bill spikes, time wasted on manual infrastructure reviews, and onboarding friction for new engineers. We A/B tested all three across different segments to find what resonated fastest.

"MSH rebuilt our entire cold email infrastructure from zero. By month two we had more qualified pipeline than our entire previous year of founder-led sales. They understand deliverability in a way most agencies simply don't."

— Arjun Sharma, CRO · Nexus Cloud

By the end of the 90-day sprint, Nexus Cloud had 47 qualified meetings on record with engineering managers and CTOs across their target ICP — enough to anchor a strong pipeline narrative for their Series A pitch deck. They continued with us on a retainer to scale the system further.
