“Working with Advanced Client has completely transformed my pipeline.
I’ve worked with other partners before, but no one delivered like this.
From day one, they laid out a clear strategy, handled all the technical setup, and within days the meetings started flying in.
Some mornings I’d have three new bookings in minutes and one day I had twelve calls back-to-back.
They’re responsive, relentless, and genuinely know what they’re doing.
If you need a team that can fill your calendar with qualified leads, Advanced Client is it.”

Frequently asked questions
Everything you need to know about how Advanced Client works.
What is GTM consulting and how is it different from a sales agency?
GTM consulting means designing and installing the go-to-market system your team owns and operates — not running campaigns on your behalf. A sales agency does the work for you and takes the knowledge with them when the contract ends. Advanced Client builds the strategy, playbook, tooling, and processes inside your business so your team can execute and scale without depending on us, an agency, or any single individual.
Who founded Advanced Client and what is their background?
Advanced Client was founded by Tom Grainger, a B2B GTM specialist with a track record of building outbound systems across SaaS, agencies, and professional services companies. Tom is a recognised Instantly.ai expert partner and has worked with over 30 B2B brands to design and install outbound motions that reduce founder dependency and create repeatable, documentable pipeline generation.
What does "investor-grade GTM" mean?
Investor-grade GTM means your go-to-market system is documented, repeatable, and not dependent on the founder or any individual rep to function. When VCs and PE firms evaluate a business, they look for evidence that revenue can be predicted, that the sales motion can be replicated at scale, and that the company isn't one departure away from losing its pipeline. Advanced Client builds GTM systems specifically designed to pass this kind of scrutiny — so whether you're raising a Series A or preparing for an exit, your commercial infrastructure holds up.
What kinds of companies does Advanced Client work with?
Advanced Client works with B2B SaaS companies, agencies, and professional services businesses. Ideal clients have a high annual contract value (£10K+), an existing sales team or plans to hire one, product-market fit, and outbound activity that's either inconsistent or founder-dependent. Companies tend to be between 10 and 50 employees. We do not work with B2C brands, companies with a very small addressable market, or pre-revenue businesses.
How long does a typical engagement take?
Most outbound system design engagements run over 10–12 weeks. The first phase covers ICP definition and segmentation. The second phase builds the documented playbook and outbound motion. The third phase installs the tech stack, RevOps workflows, and hiring framework. By the end, the client owns a fully transferable GTM system their team can run independently.
What results have clients achieved working with Advanced Client?
Results vary by business, but clients have reported: closing a £500K–£850K retainer (The Cosine), generating $5.7M in pipeline value (Studio X), booking 100+ calls and closing $70K in revenue (Smash Cactus Media), growing from $20K/month to $80K/month within a year (KinCreative), and generating $250K in pipeline within 10 days (Aplazer). These results reflect the quality of the GTM system installed, not one-off campaigns.
What tools and platforms does Advanced Client use?
Advanced Client designs systems around the tools that best fit each client's stage and stack. Common platforms include Instantly.ai for outbound sequencing (Tom Grainger is an official Instantly expert partner), Clay for data enrichment and signal-based targeting, and standard CRM infrastructure. The tech stack is always selected based on what the client's team can own and operate after the engagement ends.
How do I get started with Advanced Client?
The first step is booking a GTM assessment call. On the call, we'll diagnose your current outbound setup, identify the biggest gaps in your GTM system, and outline what a tailored engagement would look like. There's no obligation — if it's a fit, we'll propose a scoped engagement. If it's not, we'll tell you that too.
