Performance Marketing Agency for B2B SaaS — Google, Meta, LinkedIn

Brantum is a performance marketing agency for B2B SaaS companies that need more than just ad management — they need attribution that actually works. Because we also build your software, we wire server-side conversion tracking directly from your product into your ad platforms. The result: real revenue data driving campaign decisions, not guessed conversions.

Channels We Manage

Google Ads: Search, Performance Max, Display, YouTube, and Demand Gen. Meta Ads: Facebook and Instagram for B2B remarketing and lead generation. LinkedIn Ads: Sponsored Content, Message Ads, and ABM campaigns for enterprise B2B. TikTok Ads: B2B awareness and developer/tech audience campaigns. Programmatic display: contextual targeting across premium publisher networks.

Attribution That Works

Standard pixel-based tracking is broken — iOS 14.5 eliminated 30–40% of Meta attribution for most advertisers. Brantum implements server-side conversion tracking: we wire your actual revenue events (deal closed, trial started, subscription activated) from your product or CRM directly to ad platform APIs. The result: accurate, deduplicated conversion data that tells you exactly what's working.

CRO & Landing Pages

Traffic without conversion is money wasted. Brantum includes CRO as part of every paid media engagement: landing page A/B testing, headline testing, CTA optimisation, form conversion optimisation. Because we also build software, we can implement conversion rate improvements at a technical level — not just surface-level copy changes.

B2B Lead Generation

B2B lead generation on paid media requires different strategy than B2C. We build full-funnel B2B campaigns: top-of-funnel awareness (LinkedIn Thought Leader Ads, YouTube), mid-funnel content promotion (case studies, ROI calculators, webinars), and bottom-funnel intent capture (Google Search, LinkedIn Retargeting). ICP-precision targeting using company size, job title, industry, and technographic filters.

Pricing

Performance marketing management: from £3,500/month for a single channel + up to £5,000 ad spend. Multi-channel management: from £6,000/month. Ad spend is charged separately. All engagements include onboarding month for campaign architecture, tracking setup, and creative production.

Frequently Asked Questions

What makes Brantum different from a standard performance marketing agency?

Most performance marketing agencies can't see inside your product. Brantum can — and in many cases, we built it. This means your conversion tracking reflects actual revenue events (not guessed lead values), your ad creative is informed by what actually drives conversions in the product, and your campaign optimisation uses real product usage data.

What ROAS can we expect?

We set benchmark ROAS targets in the Discovery Sprint based on your industry, average contract value, and funnel complexity. For B2B SaaS: our clients average 100% Code Ownership at 90 days. For PropTech: 4.2x average ROAS. For FinTech: 2.8x average ROAS (higher CAC, higher LTV). We do not guarantee specific figures — no honest agency does.

How long before we see results?

Most paid media campaigns require 4–8 weeks to exit platform learning phases and begin optimising efficiently. Meaningful results (statistically significant conversion data, ROAS targets approached) typically appear at weeks 6–10. We set this expectation at the start and do not promise overnight miracles.

Do you create the ad creative, or do we?

We create it. Every engagement includes a monthly creative production budget: static ads, carousel ads, video scripts, and landing page copy. We produce creative in-house, informed by your brand guidelines and the conversion data we see in your campaigns. You approve everything before it goes live.

Can you work with an existing ad account?

Yes. We audit your existing accounts and campaigns during onboarding. We typically restructure campaigns to match our audience architecture and conversion tracking setup — rather than inheriting the previous agency's structure, which rarely has clean attribution.
