Account-Based Marketing Agency London for B2B Buying Groups
Your ideal accounts are out there. They just do not know you exist yet.
An account-based marketing agency helps a B2B team choose named accounts, map the buying group and run the messages, channels and sales handoffs that support a specific commercial decision. It is not broad lead generation with a new label, and it cannot guarantee meetings, pipeline or revenue. Integrated.Social runs ABM from London for B2B teams with high-value accounts; start with a 30-minute call to agree the account list.

The Reality of Modern B2B Buying
Map the buying group from account evidence, not a universal stakeholder count or average journey. Commercial, technical, financial and risk roles can need different proof before the same purchase progresses.
The practical implication:
Make relevant evaluation evidence available before formal outreach, then agree how sales will use account engagement signals. Presence and useful content can support consideration, but they do not guarantee a place on a shortlist.
Buying Committee Personas We Target
Every enterprise deal involves multiple stakeholders with different priorities, concerns, and decision criteria. We create persona-specific content and engagement strategies for each role in the committee.

The internal advocate who builds consensus, navigates politics, and drives urgency
ABM Models: 1:1, 1:Few, and 1:Many
We operate across all three ABM tiers, and most clients deploy a blended approach that matches investment to account value.
| ABM Tier | Ideal Account Profile | Core Deliverables & Scope |
|---|---|---|
| 1:1 Strategic ABM | Enterprise deals >$250K ACV with 6–12 month cycles | Bespoke campaigns for your top 5–15 named accounts. Fully personalized content, executive outreach, and account-specific landing pages. |
| 1:Few Cluster ABM | Mid-market segments with shared pain points and similar buying committees | Shared campaigns for clusters of 15–50 accounts grouped by industry vertical, tech stack, or buying stage. Persona-specific messaging at scale. |
| 1:Many Programmatic ABM | Volume pipeline generation with efficient cost-per-engaged-account | AI-powered targeting of 100–500+ accounts using intent signals, firmographic filters, and automated multi-channel orchestration. |
See how agentic AI supports intent monitoring, personalization, orchestration, and engagement scoring across the tiers. Agents draft; a named senior person signs off.
90-Day ABM Delivery Framework
We scope ABM programs in 90-day sprints, with agreed milestones, a named owner and pipeline measurement. The framework sets the work and review cadence; it does not promise pipeline within a fixed period.
Days 1–30: Foundation
- ICP refinement and target account list (TAL) build
- Buying committee mapping per account tier
- Intent signal baseline from 6sense / Bombora / LinkedIn
- Content audit and gap analysis per persona
- Measurement framework and attribution model setup
Days 31–60: Activation
- Persona-specific content production (whitepapers, case studies, POV pieces)
- Multi-channel campaign launch: LinkedIn Ads, programmatic display, email sequences
- Sales enablement assets and talk tracks per buying stage
- Account-specific landing pages for 1:1 tier
- Weekly pipeline review cadence with sales leadership
Days 61–90: Optimization
- A/B testing of messaging, creative, and channel mix
- Account engagement scoring and progression analysis
- Pipeline influence attribution reporting
- Expansion of winning plays across account tiers
- Quarterly business review with executive stakeholders

Why Integrated.Social for ABM
ABM is a B2B approach to named accounts and complex buying groups. Persona research and approved messaging can also support B2C and ecommerce brands selling to business partners or institutions; this is not consumer account targeting.
Experience in Complex B2B
We have worked with enterprise technology, fintech, SaaS, and regulated industries. The account plan starts with the buying roles, evidence needs and approval constraints of your market.
Agentic AI at Scale
Our Gemini Enterprise AI environments support multi-tier ABM, intent monitoring, content personalization and channel orchestration. Agents draft; a named senior person signs off.

Read the London B2B agency comparison →Two personas. One product. A persona-led campaign that supported a funding round.
A UK personal finance app was failing because it was targeting one audience with one message. The audience had two distinct personas: the Rational Planner (analytical, spreadsheet-driven, ROI-focused) and the Aspirational Fashionista (lifestyle-led, social-proof-driven, identity-focused). By rebuilding the entire acquisition funnel around each persona’s decision triggers, running a structured A/B testing program and deploying persona-specific creative, the campaign supported a multi-million pound funding round. This is a B2C persona example, not an ABM result or evidence that marketing alone secured the funding.
“ABM is not about targeting accounts. It is about understanding every person in the buying group, what they care about, and what will move them from awareness to action. The Rational Planner and the Fashionista were both right, they just needed completely different conversations.”Read the full case study
Five-persona buying committee: +312% qualified pipeline in 90 days and £2.4M pipeline in 6 months
A B2B SaaS infrastructure provider had a pipeline that had stalled. The problem was not the product, it was a single generic message being sent to a five-person buying committee where every stakeholder had fundamentally different priorities. By rebuilding the ICP, mapping the full buying committee, and deploying persona-specific content sequences across LinkedIn, email, and programmatic, the campaign generated +312% qualified pipeline in 90 days and £2.4M pipeline in 6 months (ABM only).
“In complex B2B, the CFO and the Head of Engineering are both in the room - but they are solving completely different problems. ABM only works when you have a distinct message, a distinct proof point, and a distinct CTA for each of them.”Read the full case study
Financial services
FinTech marketing agency London: ABM, AI search and paid media
A FinTech marketing agency helps payments, lending, wealth and B2B finance firms reach buyers through search, AI answers, account-based marketing and paid media, written with financial promotion rules in mind. Integrated.Social is a senior-led London option with published pricing and ABM experience; your compliance owner still approves every claim before it goes live.
FinTech content marketing
Fintech buyers check claims carefully, so content has to be specific and approved. We build a short library around the questions your buyers and their risk teams actually ask: how the product works, what it costs to adopt, how data is handled and where it fits alongside existing providers. Each piece goes to your compliance owner before publication. Agents draft; a named senior person signs off, and your compliance approver has the final word.
SEO and AI search for financial services
Search and AI answers often shape a fintech shortlist before sales hears about it. We check that your priority pages are crawlable, answer buyer questions in the first paragraph and describe your firm consistently, then track a fixed prompt panel across ChatGPT, Perplexity, Gemini and Google AI Overviews. That shows where you appear and where you do not; it is not a promise of rankings, citations or leads.
