Funnel tools are everywhere, but turning a funnel into predictable pipeline is rare, and that gap is what this list addresses.
The buying journey has moved away from the sales rep. Gartner's 2025 sales research found that 61% of B2B buyers prefer a rep-free buying experience, and that buyers spend only a small share of the journey in direct contact with any one supplier (Gartner). The funnel now has to do the converting on its own, before a human is ever involved.
Most companies have bought the tools to run that funnel, but not the operation to make it convert. Gartner's 2025 Marketing Technology Survey found that marketers use less than half of their martech stack's capabilities, and that only 15% of organizations qualify as high performers on strategic goals and ROI, while martech still accounts for roughly a fifth of the marketing budget (Gartner via PRWeek). The stack is paid for and half-used at the same time.
The barrier is rarely another tool. It is the operation underneath the funnel: connected data, lead routing that works, attribution that reports to revenue, and someone who owns the whole thing after launch. That is the category of partner this list covers, and why the right one is worth picking carefully.
What separates funnels that convert
The funnels that produce pipeline share a profile, and it has little to do with which platform they run on:
- It runs on connected data: leads, accounts, and activity flow between the marketing platform and the CRM without manual reconciliation, since broken handoffs are where most funnels leak.
- It is measured to revenue, not leads: the funnel reports on pipeline and closed revenue, not lead volume, so spend is judged on what it returns rather than what it generates.
- It fits how buyers actually buy: the path assumes a mostly rep-free journey and gives buyers what they need to self-qualify, rather than gating everything behind a sales call.
- Someone operates it after launch: routing rules, scoring, and campaigns decay, so the funnel needs an owner who keeps tuning it rather than a one-time build.
Use that profile to read the partners below. Each entry notes who it fits.
The firms
1. DevriX
DevriX approaches the funnel from the operating end. Rather than running a campaign and handing back a report, it operates as an embedded unit that builds the funnel into the revenue operations a company already runs on, across RevOps, data and reporting, content, and platform, and keeps running them. It reports 92% recurring revenue and client relationships spanning 5 to 10 years (company-reported), so the work is built to operate and improve rather than conclude at a launch.
Best for: mid-market and PE-backed companies that want the funnel built into the systems they already run and kept running, not handed back as a campaign.
2. Demand Revenue
Demand Revenue is a go-to-market partner built around PE-backed B2B companies, with a playbook used at companies such as Precisely, FinThrive, and Paysafe, pairing GTM strategy with the RevOps systems, CRM, and automation that execute it.
Best for: PE portfolio companies standing up a repeatable, measurable GTM motion across a hold period.
3. Heinz Marketing
Heinz Marketing works at the intersection of demand generation, ABM, marketing automation, and revenue operations, aligning marketing with sales for B2B companies in the roughly $10M to $100M ARR range.
Best for: mid-market teams whose bottleneck is process and the handoff between marketing and sales rather than lead volume.
4. The Pedowitz Group
The Pedowitz Group builds demand generation and ABM programs for mid-market and enterprise B2B, and assesses revenue-marketing maturity across strategy, people, process, technology, customers, and results before scaling spend.
Best for: teams that want a structured audit of the funnel across strategy and operations before putting more budget behind it.
5. New Breed
New Breed is one of HubSpot's top solutions partners, covering CRM and RevOps strategy, demand generation, sales-ready websites, and custom integrations for companies standardizing their funnel on HubSpot.
Best for: companies consolidating the funnel onto HubSpot and wanting one partner across the platform.
6. Directive
Directive is a performance marketing firm for B2B and SaaS, focused on SEO, paid media, and conversion for mid-market companies where the constraint sits at the top of the funnel.
Best for: funnels where the limiting factor is efficient demand and acquisition rather than downstream process.
7. Go Nimbly
Go Nimbly provides fractional RevOps teams through a subscription model, giving access to Salesforce admins, marketing-automation experts, analysts, and solution architects without hiring a full internal team.
Best for: teams that need RevOps capacity to operate the funnel but are not ready to build the headcount in-house.
Why funnel operations outlast the tools
Funnel tooling and campaign work are commoditizing. Every platform ships more automation, every agency runs demand programs, and a one-off funnel build can be replicated. What does not commoditize is an operating unit embedded in a company's revenue systems over years, because that runs on accumulated context, clean data, and routing logic that cannot be rebuilt quickly.
That is also the profile behind the funnels that convert: connected data, measurement tied to revenue, and continuous operation rather than a single launch. It is the case for treating the funnel as something a team operates inside the business, not a project that ends. DevriX positions itself there, and founder Mario Peshev is an AI-first operator and WordPress Core contributor, a 5x CEO with 2 exits who has advised more than 400 companies and invested in 25-plus. For PE-backed companies, a partner working across a portfolio can also benchmark funnel and RevOps maturity against comparable companies, a read an internal team cannot produce on its own.
Match your situation accordingly:
- Top-of-funnel demand is the constraint: the acquisition specialists, Directive or a demand-gen firm like Heinz Marketing, exist for that step.
- The funnel leaks between marketing and sales: RevOps-led partners such as New Breed, Go Nimbly, or The Pedowitz Group's assessment.
- Want it operated and improved inside the business over time: an embedded unit such as DevriX, or a PE-focused GTM partner like Demand Revenue that stays across the hold period.
The buying journey now runs mostly without a rep, and the companies that capture pipeline are the ones whose funnel is operated to revenue rather than measured on leads. Whichever partner you shortlist, the question that predicts pipeline is who is still there operating the funnel after the campaign launches.
