Disclosure and methodology
Kiin runs Google Ads for B2B SaaS companies and is on this list — last, because we do not sell it standalone. Every fact about another agency was read from that agency's own site on 14 September 2026; where something is not stated, the entry says so.
Scored on: B2B focus · brand and non-brand reported separately · offline conversion import from the CRM · pricing and contract transparency · verifiable credentials (Google Partner status, named clients). Not scored on: size, awards, design.
Three tests for a B2B Google Ads agency
- Brand and non-brand in separate reports. A blended 5% conversion rate hides a 0.4% non-brand one. If the agency's deck shows one number, that is the test failed.
- Offline conversions imported from the CRM. Without it, Google optimises toward form fills, and Google is very good at finding people who fill forms.
- A plan for the 95% who do not convert. Display remarketing is not a plan. In B2B the Google visitor should land in a LinkedIn retargeting pool, which needs an agency that runs both.
The agencies
1. Getuplead — best fixed-fee B2B SaaS Google Ads specialist
Kamel Ben Yacoub and Katia González's agency is Google-first for B2B SaaS, with senior-only staffing and the clearest terms on this list: fixed fee, no long-term contract, no minimum ad spend. Named clients include Adobe, Siemens, Snowflake and NTT Data; 5.0 on Clutch. Google Partner and Microsoft Advertising certified.
Tradeoff: the fee is not published, and "no minimum spend" is a commercial term, not a performance one — a $2,000-a-month category budget still learns slowly.
2. KlientBoost — best for Google Ads plus conversion rate optimisation
A large performance agency whose distinguishing service is CRO next to paid search, so the landing page and the campaign are worked by the same vendor. Several hundred published case studies, fees tiered by complexity rather than percentage of spend, and a stated 83% of client goals hit in Q2 2026. Airbnb, Segment and Juniper Networks named.
Tradeoff: not B2B-exclusive; process shape suits mid-market more than a 40-person startup.
3. AdConversion — best for Series A–C SaaS with no long-term contract
Silvio Perez's education-plus-agency runs Google Ads for venture-stage SaaS with a proprietary optimisation platform, in-house creative and dashboards that connect ads to revenue. ActiveCampaign, Mixpanel, Checkr and Showpad are named. The 30-day money-back guarantee is rare.
Tradeoff: the educational framing is overhead if you just want the work done; pricing is not published.
4. Powered by Search — best for paid search inside a pipeline-guaranteed demand-gen programme
Paid search as one lever in a programme with a stated outcome guarantee — 30% more sales-ready opportunities in 90 days — and HubSpot operations to make the CRM side of measurement work. Elastic, Basecamp, Varonis and SentinelOne named, with pipeline figures per case.
Tradeoff: you are buying a programme, not a Google account; minimums not stated.
5. Hey Digital — best for B2B SaaS Google Ads with landing pages and creative in-house
B2B SaaS exclusively, with the landing pages and creative that Google accounts usually lack built in-house. Published results for PostHog and Toggl. Strong execution breadth across paid search and paid social.
Tradeoff: no location or pricing on the site; measurement method less visible than execution.
6. Directive — best for enterprise B2B paid search at scale
The largest agency here, running paid search for mid-market and enterprise software — Calendly, Gong, ZoomInfo, Adobe, Cisco — with proprietary tooling and a global footprint.
Tradeoff: enterprise minimums; wrong shape below mid-market.
7. Ginger Digital — best for UK SMEs that want Google and LinkedIn from one small team
A Berkshire PPC agency running Google, YouTube, Bing and LinkedIn with video production in-house; Fujitsu, BSI Group, Korn Ferry and Hampshire Trust Bank named. The lowest budget guidance on this list, and the only UK-based entry.
Tradeoff: at £500–£2,000 a month you are testing one channel, not running a programme. Right for a UK SME; wrong for a SaaS company that needs LinkedIn, retargeting and conversion layers together.
8. Kiin — best for Google as the capture layer next to LinkedIn — never on its own
Google Ads inside Full Paid Media at $5,500 a month flat: category, competitor and brand search kept in separate campaign groups and separate reports; PMax and remarketing only on real conversion history; offline conversion import from HubSpot, Salesforce or Pipedrive; every Google visitor into the LinkedIn retargeting pool. Giga Energy's head of marketing: "They've 9x'd the number of deals in the pipeline directly from LinkedIn and Google." Why we will not run Google alone for B2B SaaS is on the SaaS PPC agency page.
Where we are the wrong choice: Google-only briefs, ecommerce, PLG under $2,000 ACV, or a media budget under roughly $10,000 a month all-in.

How to choose
- "Do you report brand and non-brand separately?"
- "Do you import offline conversions from our CRM?"
- "Who owns the ad account?" You should.
- "What happens to a Google visitor who does not convert?"
- "Is the fee a percentage of spend?"
The same five questions with what good answers sound like are on the SaaS PPC agency page, and the multi-channel version of this list is best B2B paid media agencies.
