What Advanced Client does

Advanced Client is a London-based go-to-market agency that installs what it calls AI-powered revenue operations and outbound systems for B2B companies. Its GTM engineering work covers TAM mapping, buying-signal detection, outbound infrastructure, CRM architecture and inbound lead qualification, all built inside the client's own tools. It sells this as a GTM Sprint (one channel, one ICP, one motion) or as a Forward Deployed GTM Engineer embedded in the client's business. A separate LinkedIn Ads service runs named-account ABM campaigns with a phone-first conversion motion. Its site frames the delivery method as the AC Method, a four-stage path from audit to handover, and says the client owns everything built.

  • AI RevOps and GTM engineering
  • GTM Sprint (single-channel outbound)
  • Forward Deployed GTM Engineer
  • TAM mapping, enrichment and scoring
  • Buying-signal systems routed to CRM
  • LinkedIn Ads (ABM)

Who Advanced Client fits

Its pricing page sets clear entry criteria: product-market fit, at least $1M in annual revenue or venture backing, an ACV of $10K or more, and an existing sales team or a plan to hire one. Its homepage says it is not a fit for B2C or consumer brands, pre-PMF startups, companies without a sales team, or buyers who want to rent SDR seats. It works with HubSpot, Salesforce or Attio as the CRM and operates globally from London.

  • Its homepage says it was founded in 2023 and is based in London, operating globally.
  • Its homepage claims 30+ B2B companies served, 2,000+ sales meetings booked and eight figures or more in pipeline created.
  • Its homepage cites a 5.0 rating on Clutch and lists 11 named case studies.
  • Its methodology page says the two founders lead every engagement and that it takes on only a handful of teams at a time, with no juniors or account managers.

How Advanced Client works

Its methodology page lays out a 90 to 120 day path. Weeks 1 to 2 cover a CRM, stack and sales process audit, ICP definition and a full TAM map. Weeks 2 to 3 build buying-signal models from sales call analysis and feed them into the CRM. Weeks 3 to 4 set up multichannel cadences, email infrastructure, CRM routing and prioritized phone lists, with first meetings targeted inside 30 days. After that it refines copy and signals, documents the systems and trains the team, with handover by day 120 or an ongoing retainer. Tools named include Clay (with Claude for account qualification), White Whale for signal models, Instantly, Prospeo, and HubSpot or Salesforce. Phone is described as the primary channel, with cold email and LinkedIn alongside. Clients work with the founders in a private Slack channel.

Its site names Tom Grainger (CEO and co-founder) and Louis Young (COO and co-founder). It lists London as headquarters and gives 2023 as the founding year.

Published results and clients

These are Advanced Client's own claims from its website. We have not verified them independently.

  • Its case study page says it generated $4.6M in pipeline and $447K in closed-won revenue for m3ter from 42 enterprise meetings.
  • Its case study page says Verifile closed $312K in revenue and booked 17 FTSE 100 meetings, with the system live in 28 days.
  • Its case study page says it built and transferred 7 tools with about 15 live buying signals for RAIN Group over 12 weeks.
  • Its case study page says m3ter's LinkedIn Ads cost per lead fell from $5,171 to $334.

Engagement and pricing

Plans start at $5K a month with a 3-month minimum. Its pricing page lists the GTM Sprint at $5K a month and the Forward Deployed GTM Engineer at $10K a month, both with 3-month minimums; the FAQ says implementation starts at $15K. LinkedIn Ads management is a flat $3K a month retainer plus ad spend. Tool licences of roughly $500 to $1,500 a month sit in the client's own accounts. The page calls prices directional and says Sprint fees are credited if you upgrade.

Advanced Client strengths and trade-offs

Strengths, based on what its site publishes:

  • Publishes prices and minimum terms for each package
  • Builds in client-owned accounts with full handover
  • Founders deliver every engagement
  • Names its tool stack and timeline openly

Trade-offs to weigh:

  • 3-month minimum on every tier
  • Small founder-led team limits capacity
  • Implementation fee terms are stated two ways on the pricing page
  • Not built for low-ACV or pre-PMF companies

How Advanced Client compares

GTM engineering and outbound agencies differ mostly in who owns the system afterward. Some run outbound for you as a managed service, others build the data, signal, and routing layer inside your own CRM and tools and hand it over. Ask which model you are buying, what you keep if you stop paying, and how results are measured.

Advanced Client publishes more about price, eligibility and tooling than most outbound shops, so buyers can check fit before a call. Ask how the implementation fee interacts with the Sprint's 3-month minimum, since the pricing page gives two readings. Because the founders deliver everything and capacity is limited, ask about start dates. Teams below $10K ACV, without salespeople, or that want rented SDRs fall outside its stated criteria, and the phone-first motion suits teams with reps who will call.
