If you use HubSpot, you have probably seen the same paid media failure: the ad dashboards look busy, the CRM looks busy, and nobody can explain which campaigns created pipeline. The best B2B paid media agencies solve that measurement gap before they scale spend. They connect targeting, conversion tracking, sales stages, and revenue reporting into one system your marketing and sales teams can trust.
Disclosure: Selworthy publishes this comparison and appears on the list. We reviewed each agency using public service pages and HubSpot Solutions Directory profiles available on August 26, 2026. We did not use private proposals, unpublished client data, or pay-to-play rankings. The order prioritizes fit for companies that want paid media performance connected to HubSpot reporting.
Our position is simple. A paid media agency should not stop at clicks, form fills, or a platform-reported return on ad spend. For B2B companies with complex sales cycles, the useful question is whether an agency can connect paid search and paid social activity to qualified pipeline, closed-won revenue, and the sales process inside your CRM.
HubSpot can manage and report on Google Ads, sync leads into the CRM, and send lifecycle or deal events back to Google for campaign optimization. That capability is the starting point, not the finish line. The agency still has to design the lifecycle stages, campaign architecture, attribution model, and reporting rules that make the data meaningful. HubSpot's Google Ads integration documents the underlying connection.

| SmartBug Media | Full lifecycle marketing and platform support | Paid media tracking across major ad networks | Elite partner with HubSpot ad tracking and attribution services |
| Six & Flow | Multi-region RevOps and demand generation | Paid search and paid social | Elite partner with HubSpot reporting credentials |
| Ironpaper | B2B demand generation and ABM | Paid campaigns, PPC landing pages, and lead generation | HubSpot agency with attribution and ROI measurement services |
| Dragon360 | B2B technology and SaaS advertising | Performance marketing, creative, and ABM | Gold partner pairing paid strategy with custom HubSpot systems |
| Directive | Mid-market and enterprise SaaS performance marketing | Paid media focused on demos, trials, and SQLs | Platinum partner with HubSpot-centered RevOps services |
| Obility | B2B technology companies scaling paid channels | Paid search, paid social, display, and emerging channels | CRM-connected revenue dashboards; HubSpot scope should be confirmed |
| Digitopia | B2B teams needing ads plus custom dashboards | Google, LinkedIn, Meta, programmatic, and ABM | HubSpot reporting and paid media influence dashboards |
| Kalungi | B2B SaaS companies outsourcing the marketing function | Paid media within a full go-to-market program | Diamond partner with HubSpot optimization and reporting services |
This is not a ranking of logo walls or media buying volume. We used a framework we call Campaign to Customer: the agency must show how paid media moves from an ad impression to a known buyer, a sales opportunity, and a revenue outcome.
The best agency for you still depends on company stage, sales motion, internal staffing, budget, and the condition of your HubSpot portal. The fix is not the agency with the longest channel list. The fix is the agency whose measurement model matches how your business actually earns revenue.
Not every B2B marketing agency is a paid media specialist. The market includes specialists for tech companies, broader professional services firms, and full-service shops that sell media management alongside other work. A digital marketing or content marketing agency may offer content strategy, content production, organic search, search engine optimization, digital PR, web development, and conversion rate optimization. Those marketing efforts can build brand authority, organic traffic, and long-term organic growth engines. They can also support sales and help marketing teams generate leads. For this comparison, however, they did not replace evidence of hands-on paid media campaigns, CRM-connected performance tracking, and revenue attribution.
We also did not treat a long channel menu as proof of a strong media strategy. Most agencies can show platform reports, so vanity metrics did not earn a place on this list. Display advertising, retail media, and media campaigns across multiple channels can help a company generate demand, but only when the agency explains the audience, offer, landing page, analytics infrastructure, and optimization process. Whether the pitch calls it demand gen, digital demand generation, performance marketing, or customer generation, a capable media buyer should show how ad campaigns and demand generation campaigns generate qualified leads, how marketing automation routes them, and how sales feedback improves media efficiency. We excluded any general marketing agency that could not make that connection.
A HubSpot logo in a proposal does not prove that the agency can build useful revenue attribution. Ask to see the reporting architecture. A complete model has five connected layers, and each layer answers a different business question.
Attribution models still need judgment. First-touch reporting can show how demand entered the system. Last-touch reporting can show what happened before conversion. Multi-touch models can distribute credit across a longer journey. None is a perfect statement of causation. The agency should present the chosen model, its assumptions, and the data it excludes so leadership can interpret the result responsibly.
Ask about reconciliation, too. HubSpot, Google Ads, LinkedIn, Meta, analytics tools, and finance systems can count events differently because their identity rules, attribution windows, and update timing differ. A credible reporting process explains why totals diverge and which system is authoritative for campaign optimization, pipeline forecasting, and booked revenue.
The first sales call should reveal how the agency thinks, not only what it sells. Use these questions to compare operating models across agencies with very different team sizes and service menus.
Selworthy is a HubSpot Gold Solutions Partner that connects paid media, RevOps and CRM architecture, and analytics and reporting under one operating model. The public HubSpot directory lists paid advertising among its services, while Selworthy's service pages cover Google, Meta, and LinkedIn ads alongside custom dashboards and attribution.
The practical difference is ownership. The same team can inspect the ad account, lifecycle stages, deal pipeline, conversion tracking, and dashboard logic. That removes the common gap where a media buyer blames the CRM and a CRM consultant blames the campaigns.
Selworthy is headquartered in Shallotte, North Carolina, works with clients across the United States, and has been a HubSpot partner since 2016. It is a Gold Solutions Partner today.
New Breed's professional services combine Revenue Operations, demand generation, paid advertising, content, SEO, website optimization, and creative work in a HubSpot-native model. Its HubSpot Solutions Directory profile currently lists Elite status and describes paid media as part of demand generation and ABM.
New Breed is built for organizations that need more than media management. Its public service language emphasizes mid-market, corporate, and enterprise teams, with paid campaigns coordinated alongside platform configuration, data, and reporting. That makes it a strong candidate when the buying problem spans several HubSpot hubs or internal departments.
SmartBug Media's Marketing Hub services explicitly cover paid media tracking, Facebook, LinkedIn, and Google Ads, HubSpot dashboards, and multi-touch revenue attribution. Its current HubSpot directory listing presents the agency as an Elite partner with a dedicated paid media capability inside a broader revenue-generation organization.
SmartBug is useful when paid advertising is one part of a larger lifecycle program. The public service set spans CRM implementation, integrations, marketing, content, and reporting, so the agency can support more than campaign execution.
Six & Flow's demand generation services combine paid media with HubSpot-centered campaign planning and performance tracking. Its HubSpot Solutions Directory profile currently lists Elite status, Paid Advertising, HubSpot Reporting certification, and delivery across EMEA and North America.
Six & Flow's public positioning is broader than ad management. The firm presents itself as a HubSpot consultancy and RevOps partner that connects people, process, data, and technology. That can be valuable when the campaign must work across regions, business units, or more complex CRM architecture.
Ironpaper's HubSpot agency services focus on B2B companies, demand generation, account-based marketing, attribution, reporting, and ROI measurement. The agency describes HubSpot as the central marketing system for lead generation and sales nurturing, including PPC landing pages and campaign optimization.
Ironpaper's strength is the connection between buyer engagement and the sales funnel. Its public materials focus on qualified leads, account-based programs, sales enablement, and attribution rather than treating paid media as a separate channel.
Dragon360's HubSpot profile describes a digital advertising agency and Gold Solutions Partner focused on B2B technology and SaaS. The agency pairs performance marketing, creative, ABM, and paid strategy with custom HubSpot systems, revenue intelligence, data architecture, and platform governance.
That combination makes Dragon360 one of the clearest specialist fits on this list. Its public positioning starts with paid advertising, then connects campaign execution to the HubSpot systems that marketing and sales need for measurement.
Directive's paid media practice focuses on B2B SaaS and technology companies, with campaign goals tied to demos, trials, SQLs, pipeline, and closed-won revenue. Its current HubSpot directory listing shows Platinum status and includes paid media, Revenue Operations, CRM optimization, and marketing automation.
Directive's public methodology emphasizes first-party data, financial modeling, conversion-focused creative, and revenue accountability. Its Revenue Operations service specifically describes turning HubSpot into a revenue operating system.
Obility's paid social service is built for B2B technology and software companies. It covers LinkedIn, Meta, Reddit, ABM, retargeting, creative testing, and reporting tied to pipeline and closed-won revenue. Its public pricing page also lists paid search, display, customizable performance dashboards, offline conversion tracking, and CRM-connected opportunity and revenue reporting.
Obility is a strong paid media specialist, but its public reporting model is described as CRM-connected rather than exclusively HubSpot-native. That is not a weakness by itself. It means a HubSpot user should confirm the exact data model, attribution method, integration ownership, and dashboard destination during discovery.
Digitopia's paid media services cover Google Ads, LinkedIn, Meta, programmatic advertising, ABM, retargeting, conversion optimization, and multi-touch attribution. The agency also publishes a dedicated HubSpot reporting service with campaign, paid media influence, conversion, and multi-source attribution dashboards.
The connection between those offers is the reason Digitopia belongs on this list. Buyers can evaluate paid campaign execution and the HubSpot reporting layer as explicit services rather than assuming one is included with the other.
Kalungi's outsourced B2B SaaS marketing service combines fractional CMO leadership, paid media, ABM, content, conversion optimization, automation, reporting, web development, and HubSpot implementation. The agency's public site identifies it as a HubSpot Diamond partner.
Kalungi is the broadest outsourced-department option in this comparison. Paid media sits inside a larger go-to-market program rather than as a standalone media buying engagement. That model can work well when a SaaS company needs leadership and execution at the same time.
A polished proposal can hide a weak operating model. Before you compare creative concepts or channel plans, ask each agency to walk through the Campaign to Customer path using your actual systems.
Migration is sometimes the right answer. It is almost never the right opening move. A capable agency should first determine whether your current HubSpot portal, ad accounts, and tracking can support the decisions you need to make.
A B2B paid media agency plans, launches, measures, and improves advertising across channels such as Google, LinkedIn, Meta, display, and programmatic media. The best agencies also account for buying committees, longer sales cycles, multiple stakeholders, lead quality, and the connection between ad engagement and revenue.
Ad platforms can show clicks and platform-attributed conversions, but HubSpot can connect marketing activity to contacts, companies, deals, lifecycle stages, and revenue. That connection helps your team evaluate pipeline contribution and sales outcomes rather than relying only on campaign metrics.
Not every campaign task has to happen inside HubSpot, but the agency should understand how ad data, conversion events, forms, lifecycle stages, campaigns, and deals connect. The team should also document which system is authoritative for each metric and who owns reconciliation.
There is no responsible universal budget. The right level depends on market size, average contract value, sales capacity, conversion rates, channel costs, creative production, and the amount of data needed to learn. Ask the agency to show its assumptions and the minimum viable test, then separate media spend from agency fees.
Early campaign signals can appear quickly, but pipeline and revenue evidence follows the length of your sales cycle. A useful first-quarter plan should establish tracking, launch focused tests, evaluate lead and opportunity quality, and show what the team will change next. Avoid agencies that promise a fixed revenue outcome before they inspect your data.
The best fit is the agency that can prove how it connects ad spend to your HubSpot lifecycle and revenue model. Selworthy is designed for companies that want paid media, RevOps, and reporting under one accountable team. Other agencies on this list may be a better fit when you need enterprise scale, international coverage, a SaaS-specific outsourced department, or a paid-media specialist that connects to an internally managed CRM.
You do not need another dashboard that explains what happened inside an ad platform. You need a reporting system that shows what happened after the click, where qualified opportunities came from, which marketing dollar produced evidence, and which budget decision follows.
We start with Audit, Blueprint, Build and Scale. That means we inspect the ad accounts, HubSpot configuration, lifecycle rules, conversion paths, and reporting gaps before recommending more spend. Claim your four complimentary consulting hours, and we will map the first Campaign to Customer reporting path with you.
