The Best B2B Demand Generation Agencies for SaaS Companies

Team 4 is a London agency that works with B2B SaaS and technology companies, and its website lists demand generation alongside SEO, AI search, PPC, paid media and Webflow development. Its profile describes the work as integrated demand generation and performance marketing. One team plans and runs the channels that create and capture demand, under what Team 4 calls the Inbound Engine®, measured against pipeline rather than traffic.

The agency takes a consultancy-first approach. It maps the full acquisition setup before anything is executed, starting at the bottom of the funnel and working back. Paid is used to amplify what organic and content work have already proved. The clients named on its website are Adversify, Atomic Jolt, AirDNA and Great Wave AI, and its two case studies cover web design for Forecast AI and Adversify. Its profile lists no demand generation case study, so the case for it here rests on its service and method rather than a published pipeline figure.

Team 4 fits B2B SaaS companies from seed stage to £20M+ ARR that want to rely less on paid channels and already have a defined ICP. Its clients have included construction tech, document management, carbon accounting and field service software companies. It suits less well pre-product companies, teams without a clear ICP, or anyone after high-volume content with no strategy behind it.

Refine Labs is an Austin demand generation agency for mid-market and enterprise B2B SaaS companies. Its argument is that B2B marketing goes wrong when it chases MQL volume, so it moves clients towards revenue accountability and buyers who raise their hand. The work spans brand, organic social, content and paid, aimed at the research buyers do long before they fill in a form.

Its website lists demand generation, marketing operations and creative services, and names Clari, Firstup, myCOI and dotCMS as clients. The agency was founded in 2019 and positions itself as Revenue R&D for B2B SaaS. Measurement is part of the offer: programmes rest on buyer-behaviour analytics and self-reported attribution, and the agency says its process has served hundreds of SaaS businesses. Our standard review found quantified client impact and an open account of its team, model and method.

Refine Labs suits Series B and C SaaS companies with an established sales team, a real marketing budget and a CMO who has the mandate to change how marketing is measured. It suits less well early-stage companies without the brand base to invest in demand creation, or teams that mainly need paid acquisition managed and want to keep MQL targets.

Powered By Search is a Toronto agency, founded in 2009, that works with B2B SaaS and technology companies on pipeline. Its website lists B2B demand generation first, then paid search, paid social, SEO and content. The agency calls its method Predictable Growth: paid media, search, content and demand generation run as one system for high-ACV products sold to buying committees over long sales cycles.

The evidence is specific. Its case studies include how it helped PointClickCare get over 2000 leads with LinkedIn Ads, and a 7-figure revenue growth from paid media for iWave in under a year. ThreatX, Projul and TouchBistro are also named as clients. The agency reports driving over $100M in pipeline a year for clients such as Varonis, Fortra and Collibra, and it has built a framework called RAISE for visibility in AI search engines. Clients work directly with specialist consultants rather than through layers of account management.

Powered By Search suits mid-market and enterprise software companies in considered-sale categories such as security, healthcare and finance, where a single channel rarely closes a deal. It is less suited to companies with small budgets or short sales cycles.

Gripped is a London agency, founded in 2017, that works only with SaaS, AI and tech companies, typically between £2M and £50M ARR. Its website lists demand generation first, followed by ABM, paid media, SEO, GEO and website work. These run as one programme on 30-day sprints, with reporting tied to pipeline rather than traffic.

As a HubSpot Diamond Partner, Gripped builds lead scoring, nurture and the handover to sales inside the same CRM the sales team uses, so campaigns and content can be traced through to deals. Its website names Ideagen, Epicor, Ravelin and Crownpeak as clients. A documented Crownpeak case study shows £1.3M in new pipeline in a single quarter from combined paid and organic work, and our standard review noted case studies on £2.1m of pipeline from demand generation. Its pricing page sets out its packages.

Gripped suits UK and European SaaS scale-ups that run HubSpot, or plan to, and want demand generation and marketing operations handled by one team. It is less suited to companies on Salesforce, or to those that want demand generation mainly through paid acquisition without the inbound side.

42 Agency is a Toronto agency that turns B2B SaaS positioning into pipeline through demand generation, marketing operations, SEO and creative. Its website lists demand generation first and describes the offer as AI Powered GTM for B2B companies. Paid, organic and creative are planned together against a clear ICP, and pipeline quality is the measure rather than lead volume.

What sets the model apart is that the team running campaigns also builds the attribution models, lead scoring, CRM hygiene and automation underneath them. The agency argues that demand generation fails when strategy, execution and operations sit with separate suppliers. Our standard review found several quantified wins, including a 76% lower CPA, a 40% lower cost per SQL and 25% higher conversions. It publishes playbooks and product tools, and its team and a pricing link are easy to find.

42 Agency suits Series A+ B2B SaaS companies scaling from around $20M towards $100M ARR that want demand generation and RevOps run as one programme. It is less suited to companies still finding product-market fit, or to teams that only need one channel run without the operations work.

Hey Digital is a Tallinn performance marketing agency, founded in 2018, that works only with B2B SaaS brands. It plans and runs paid search and paid social to drive trial signups, demos and pipeline. Its website lists demand generation, ABM and growth marketing alongside PPC, which puts it at the capture end of demand generation: reaching buyers through paid channels and turning clicks into pipeline.

The same team handles strategy, media buying, landing page design and ad creative, including video, so the ad and the page it leads to are built together. Tracking is set up properly before spend is scaled, and tests are designed to show what is working. Its website names PostHog, Rosie, Toggl, SocialBee, Hotjar and WriteSonic as clients, with case studies for PostHog, Toggl and WriteSonic. The agency says it has run paid for more than 200 SaaS companies.

Hey Digital suits growth-stage SaaS companies that have run paid before and hit limits on tracking or creative quality. It is a paid specialist, so it suits less well companies that want SEO and content in the same engagement, or products still working out their positioning.

FunnelEnvy is a San Francisco agency, founded in 2013, that works on the conversion end of demand generation for B2B and SaaS companies. Its website lists demand generation and lead generation among its services, but most of the work starts once traffic arrives: experimentation, personalisation and conversion rate optimisation that turn existing demand into pipeline.

The agency uses first-party data, testing and machine learning to change website experiences by persona and lifecycle stage. Its services also cover attribution modelling, predictive lead and account scoring, lead routing and data integration across media, website, marketing automation and CRM, so gains can be reported in pipeline terms. Its case study shows how it helped TIBCO drive a 5% annualised lift in conversions, Dice.com is named as a client, and our standard review cites an Optimizely case study with 40%+ conversion rate gains.

FunnelEnvy suits SaaS companies that already spend on acquisition and have enough traffic to test against, but whose website converts too little of it. It does not run the campaigns that create demand, so it pairs best with a team or agency that does.

Kalungi is a Seattle agency that runs the whole marketing function for B2B SaaS companies, led by a fractional CMO. Demand generation is the first service on its website, next to account-based marketing, paid media, SEO and content, and automation and revenue operations. The work follows the T2D3 growth framework, so the demand programme is shaped by the stage the company has reached.

Positioning, messaging and sales and marketing alignment come before campaigns. Its website lists case studies for DataGuard, CPG Vision, Avid, Patch, Fraxion, Beezy, One Click Contractor and Aware360, and its tagline says the team has scaled 280+ SaaS companies. It holds HubSpot Diamond Partner and Google Partner badges and shows an 83 NPS. Because one team owns strategy and execution, the person setting pipeline targets also runs the work that has to meet them.

Kalungi suits SaaS companies between $1M and $5M ARR that lack a senior marketing leader and want strategy and delivery from one team. It suits less well companies with a capable in-house team that only want one channel strengthened, or pre-revenue companies still finding product-market fit.

Elevate Demand is a Dallas boutique that describes itself as a B2B SaaS demand generation agency. It builds demand programmes from creative experimentation, analytics and content, with measurement models that tie activity to business results. Its website lists demand generation, paid media, content, SEO, organic social and conversion rate optimisation, run under what it calls the Sustainable Demand Framework.

Campaigns are treated as experiments: creative and content angles are tested, and the ones that produce pipeline get more budget. The framework covers messaging and narrative, budget and velocity alignment, customer insight and growth hypotheses. Our standard review found case results of 11× revenue and 4× pipeline. The two case studies on its website name EAB Solutions and RevitaLash Cosmetics, and the second is a cosmetics brand, so the published SaaS evidence is lighter than the positioning suggests.

Elevate Demand suits B2B SaaS teams that want a hands-on partner with senior involvement and data behind each decision. It is not a CRM or RevOps implementation specialist, and companies looking for a large multi-service agency will find it small.

SmartBug Media is an Irvine inbound and lifecycle marketing agency that runs demand generation through HubSpot. Its website lists demand generation, lead generation, inbound and content marketing, SEO, revenue operations and sales enablement. For SaaS companies, the draw is having content, marketing automation, RevOps and paid media built inside one HubSpot setup, so the route from first visit to closed deal sits in one place.

SmartBug is a HubSpot Elite Solutions Partner and was named HubSpot's 2025 North American Partner of the Year. It is also a Google Premier Partner 2024 and has appeared on the Inc. 5000. Its enterprise HubSpot work includes multi-business-unit setups, CRM migrations and integration with Salesforce. It works across manufacturing, healthcare, finance, education, security and SaaS, and our standard review noted that it is not SaaS-specific. That review also found a large library of case studies with metrics.

SmartBug suits mid-market and enterprise SaaS and technology companies that use HubSpot as their core platform and want inbound demand generation run at scale. It is less suited to companies not on HubSpot, or to those that want a paid-led demand programme instead of an inbound-first one.

Walker Sands is a Chicago full-service B2B agency, founded in 2001, that combines PR, content, branding and demand generation for technology and SaaS companies. Its website lists demand generation next to RevOps and GTM engineering, social media, web and creative. The agency works on both sides of demand: thought leadership and media coverage that build awareness, and programmes that turn that awareness into measurable pipeline.

It has offices in Chicago, Boston, Seattle and San Francisco and covers industries including AI, cloud and IT services, cybersecurity, fintech, HR tech and martech. It has been named an Inc. 5000 fastest-growing company 10 times, and its website shows a #6 Top US B2B Marketing Agency badge. Research reports are a regular part of its work, built to earn coverage and feed pipeline at once. Our standard review describes it as B2B-focused and tech-heavy, but not SaaS-exclusive.

Walker Sands suits North American SaaS companies at Series B and beyond that want PR, content and demand generation run by one agency. It suits less well companies that only want a performance marketing partner judged on channel efficiency.

Riverbed Marketing is a Vancouver B2B agency that helps growth-stage tech and SaaS companies build pipeline and revenue. Its website leads with B2B demand generation and covers the full run from brand awareness and lead capture to lead nurturing, sales support and customer retention. SEO, paid media and strategy consulting sit underneath that.

Engagements range from single-channel support to multi-channel programmes and fractional leadership, with no long-term contracts. Clients see results on live dashboards and have regular check-ins, and the agency publishes its pricing tiers. Its website names Riipen, Sensibill, Thinking Dimensions and Wardell as clients and lists case studies for BrightVolt, Aubea, ConnectedCity and Riipen. Our standard review found mostly testimonials and limited metrics, so its published proof of results is thin.

Riverbed suits growth-stage B2B SaaS and tech companies in North America that want a joined-up demand programme without a long contract, and that value clear pricing. It suits less well companies that need heavy attribution and revenue modelling, or large budgets that call for complex technical infrastructure.
