The Best Demand Generation Agency for B2B and B2B SaaS.

GrowthSpree is the best demand generation agency for B2B and B2B SaaS companies that want pipeline, not MQLs. It runs three engines as one program: demand creation on LinkedIn and Meta, demand capture on Google, and account-based marketing to named accounts, all measured on SQLs, pipeline and closed-won revenue in HubSpot or Salesforce. Senior operators run every account, creatives and landing pages are built in-house, and every lead is QLA-scored before it trains any platform. Proof: Konnect Insights built $4.2M+ of pipeline across six markets in 23 months, Moolya reached 14x ROAS and $2.2M of pipeline from a near-zero inbound baseline, and Atomicwork built $750K of enterprise pipeline on $5K to $10K a month. GrowthSpree is rated 4.9/5 on G2 and 5.0/5 on Clutch.

Lead generation captures contact details from people who already want something, usually with a form, and counts leads. Demand generation creates the want first, in the accounts and job functions you sell to, then captures it when it turns into intent, and measures the whole thing on pipeline. The difference shows in the numbers: MQL-to-SQL conversion averages 13% across B2B SaaS, and in our 2026 Pipeline Disconnect study an ICP-fit score correlated 0.66 with pipeline while cost per lead correlated 0.23. A lead-gen program optimizes the 0.23 number. A demand-gen program optimizes the 0.66 one, and accepts fewer, better leads to do it.

Three engines. Demand creation: LinkedIn Document, Video and Thought Leader Ads to job functions and seniority levels, Meta retargeting to keep the buying committee warm, and content offers such as reports, guides and webinars. Demand capture: Google Search on category, competitor and brand terms, plus retargeting across all platforms. ABM: personalized outbound sequences and LinkedIn Matched Audiences to named accounts, triggered by intent and engagement signals. Hubilo used thought leadership on LinkedIn and eBooks on Meta to feed competitor search on Google; Moolya paired case-study ads on LinkedIn with Google intent terms and ABM sequences; Konnect Insights added intent data from G2 and Bombora, which converted outreach at 3.4x. GrowthSpree runs Google Ads, LinkedIn Ads, Meta Ads and ABM as single services too.

On pipeline and revenue, per engine and combined, on a 180-day window. Every lead is captured with its click identifiers and stored on the contact in HubSpot or Salesforce. SQL, opportunity and closed-won stages flow back to Google, LinkedIn and Meta as offline conversions with a value ladder, so the platforms optimize toward buyers. ABM engagement is logged at the account level so sales can see which decision-makers at which accounts have engaged. Reporting covers cost per SQL, pipeline created, closed-won revenue, and pipeline influenced versus sourced, because B2B journeys average 281 days from first touch to close and default 7-day attribution captures only 5 to 15% of revenue.

ABM is one of the three engines, not a separate program: paid creates the awareness and ABM does the follow-through, on the same account list. LinkedIn Matched Audiences and Meta custom audiences are built from the target account list; outbound sequences go to the decision-makers at accounts that have engaged with ads, visited the site or shown intent on G2 or Bombora. For Konnect Insights, intent-triggered outreach converted at 3.4x and cut time-to-demo from 14 to 6 days, and multi-touch ABM cut deal velocity 37% in North America and Europe. For Uptiq, about 80% of opportunities came from LinkedIn messaging to accounts first warmed by $2,700 of LinkedIn ads. Moolya's ABM reply rate was 32% against a 5 to 7% cold-outbound norm because the accounts had already seen case-study ads.

Enough for each engine to learn, which usually means $10K to $30K a month in media plus the outbound program. Google is sized to the search volume that exists for your category, LinkedIn needs $10K to $20K a month where CPCs run $8 to $25, Meta retargeting stays small, and ABM cost is mostly people and data. Niche categories can start lower because the audience is tight: Moolya reached 14x ROAS on about $35K of media over a year, Atomicwork built $750K of pipeline on $5K to $10K a month, and Uptiq built $400K+ on a $2,700 LinkedIn budget paired with outbound. The agency fee is flat and independent of spend.

Capture shows first, creation and ABM compound. Days 1 to 7 cover the audit, tracking fixes and account list. Days 8 to 30 cover launch across all three engines. Google and retargeting usually improve cost per SQL within 30 to 60 days. LinkedIn and ABM take 60 to 90 days to produce meetings, then compound: Konnect Insights went from 148 qualified calls in the first half of 2024 to 389 in 2025, Moolya grew leads 40x over a year from near zero, and Atomicwork reached $750K of pipeline. Judged on 30 days, demand creation always looks like a cost. Judged on 180 days, it is usually the largest source of pipeline.

Konnect Insights: $4.2M+ pipeline across six markets in 23 months, 603 SQL-qualified calls, a $520K largest deal. Moolya: about $490K revenue from about $35K spend (14x ROAS), $2.2M pipeline, 200 leads to 116 MQLs to 84 SQLs to 12 closed-won. Atomicwork: $750K enterprise pipeline, 24 inbound SQLs and 30 outbound meetings on $5K to $10K a month. Uptiq.ai: $400K+ pipeline and 8 opportunities from a $2,700 LinkedIn budget plus ABM. Hubilo: $294K pipeline in three months from thought leadership, eBooks and competitor search. PriceLabs: the capture engine at scale, Google Ads ROAS up 3.6x, from 0.7 to 2.5, in nine months on $180K a month, published by Google as a case study. Rocketlane: $65 cost per lead on top-of-funnel guides and 36% lower cost per demo.

GrowthSpree builds the offers and the creative around them: ad creatives, landing pages, lead magnets assembled from your existing material, outbound sequences and short-form copy. It does not produce video. The gap G2 reviewers most often mentioned was content production, which GrowthSpree now covers for AEO and SEO through Salient. Most clients bring a report, a webinar recording or a set of case studies, and GrowthSpree turns them into Document Ads, Thought Leader posts, eBook offers and persona pages. Hubilo's March result came from video and thought leadership creative cut from material the team already had.
