The best marketing data connectors in 2026 are Fivetran (now merged with dbt Labs) and Airbyte for warehouse-first teams, Funnel, Supermetrics, Adverity, Improvado, and Windsor.ai for marketing-specific reporting, and Hightouch or Fivetran Activations for pushing modeled data back out. Pick by destination: spreadsheet and BI reporting, a data warehouse, or activation in ads and CRM.
Connectors solve one problem well: getting data out of Google Ads, Meta, LinkedIn, GA4, HubSpot, Salesforce, and dozens of other tools into one place. They do not, on their own, tell you which accounts are in market or act on that knowledge. This guide compares the top connectors on facts we verified on each vendor's site in October 2026, explains the three architectures they serve, and shows where account-level data and CRM sync fit in a B2B stack.
The three jobs a "marketing data connector" can do
Buyers search for "marketing data connectors" when they mean one of three different things. Confusing them is the most common reason teams end up paying for two tools that overlap.
- Reporting connectors pull ad and analytics data into spreadsheets, Looker Studio, or a BI tool so marketers can build dashboards. The value is normalized metrics (spend, clicks, conversions, currency, time zone) without engineering help.
- ELT pipelines load raw data from hundreds of sources into Snowflake, BigQuery, Redshift, or Databricks, where the data team models it. The value is completeness and reliability at volume.
- Activation (reverse ETL) moves modeled data from the warehouse back into CRMs, ad platforms, and marketing tools. The value is acting on the data, not just reporting it. Our explainer on reverse ETL for marketing covers this pattern in detail.
Most B2B teams need the first two and are starting to need the third. Very few need three separate vendors to get there. If the job you actually care about is activation on target accounts, see how Abmatic AI handles it natively.
Best marketing data connectors in 2026: comparison table
| Tool | Primary job | Connector claim (vendor site) | Pricing model | Best for |
|---|---|---|---|---|
| Fivetran (Fivetran + dbt Labs) | ELT into warehouses, transformations, and Activations (reverse ETL) | 750+ sources and 200+ destinations across connectors and activations | Published, usage-based on Monthly Active Rows (MAR), with a free tier | Data teams that want managed, reliable pipelines at scale |
| Airbyte | ELT, open-source and cloud | 700+ connectors | Published credit-based cloud plans, capacity-based Pro and Enterprise tiers on quote, and free self-managed open source (Airbyte Core) | Engineering-led teams that want control or self-hosting |
| Funnel | Marketing data hub: collect, normalize, send to BI, warehouses, and AI tools | 600+ marketing connectors, 36+ destinations, plus Funnel MCP | Published starting tiers billed annually; Enterprise on quote | Marketing teams that want clean cross-channel data without a data engineer |
| Supermetrics | Reporting connectors into Looker Studio, Sheets, Excel, and warehouses | Hundreds of listed data sources on its connectors page | Published, based on destination, number of data sources, users, and connected accounts | Agencies and in-house marketers building dashboards |
| Adverity | Enterprise marketing data integration, transformation, and data quality | Connectors across marketing, advertising, sales, and finance | Not published; fully custom quote | Large brands and agencies with complex governance needs |
| Improvado | Marketing data platform with BI and AI layers | Pre-built source catalog (no total stated on pricing page) | Published free and MCP-only tiers; Advanced and Enterprise on quote | Mid-market and enterprise marketing analytics teams |
| Windsor.ai | Lightweight connectors into BI, Sheets, and warehouses | 350+ data sources | Published monthly plans, a free tier, and Enterprise on quote | Small teams that want low-cost reporting connectors |
| Hightouch | Reverse ETL, composable CDP, and agentic marketing | Activation into CRMs, ads, and marketing tools | Not published beyond a free Basic Reverse ETL tier | Teams with a mature warehouse that want to activate audiences |
Connector counts are vendor claims and are counted differently: some count each API endpoint, others count each platform. Treat them as a rough scale, then check that the specific sources you need are supported with the fields and history depth you need.
Vendor notes that matter in 2026
Fivetran and dbt Labs are now one company
Fivetran announced the completion of its all-stock merger with dbt Labs on June 1, 2026, after first announcing the deal in October 2025. George Fraser remains CEO and Tristan Handy is President. Fivetran had already added reverse ETL by acquiring Census in 2025, now offered as Activations. For buyers, this means one vendor now spans ingestion, transformation, and activation, which can simplify procurement but also concentrates your dependency.
Airbyte is the open-source default
Airbyte offers a free self-managed open-source edition alongside its cloud plans, which gives engineering-heavy teams a way to avoid usage-based pricing entirely if they are willing to run infrastructure. Its cloud plans split into volume-based credits and capacity-based plans priced by dedicated compute.
Funnel, Supermetrics, Adverity, and Improvado are marketing-first
These tools are designed for marketers, not data engineers. They normalize ad metrics across channels, handle currency and naming differences, and push data into the destinations marketers use. Funnel and Improvado both now offer MCP access so AI assistants can query marketing data directly.
Pricing models differ more than prices
Usage-based models (Fivetran MAR, Airbyte credits) scale with data volume and change frequency. Seat and source-based models (Supermetrics) scale with how many accounts and people you connect. Custom-quote models (Adverity, Hightouch enterprise) depend on negotiation. Model your own volume on each before comparing sticker prices.
How to choose a marketing data connector
- Start from the destination. If marketers report in Looker Studio or Sheets, a reporting connector is enough. If you have a warehouse and a data team, use an ELT pipeline. If you need to push audiences back to ads and CRM, add activation.
- List your must-have sources and fields. LinkedIn Ads company-level demographics, GA4 custom dimensions, and Salesforce custom objects are where connector coverage varies most.
- Check history depth and refresh frequency. Ask how many months of historical data each connector backfills and how often it syncs.
- Model total cost at your real volume. Change-heavy sources like ad platforms can drive usage-based costs up quickly.
- Decide who owns it. A tool marketers can run without a ticket queue often beats a more powerful tool nobody maintains.
If your real goal is account-level targeting rather than dashboards, you may not need a warehouse pipeline at all to get started. Book an Abmatic AI demo to see how account signals and CRM sync work out of the box.
Skip the manual work
Abmatic AI runs targets, sequences, ads, meetings, and attribution autonomously. One platform replaces 9 tools.
See the demo →Where account-level data and CRM sync fit
Connectors move rows. B2B revenue teams care about accounts. Ad platforms report clicks by campaign, GA4 reports sessions by user, and the CRM stores contacts and opportunities. None of those natively answer "which target accounts are engaging this week, and what should we do about it?"
There are two ways to close that gap:
- Build it in the warehouse. Load everything with a connector, resolve visitors and leads to accounts with your own identity model, score them, then push scores back to the CRM and ad platforms with reverse ETL. This is powerful, but it requires an identity graph, a data team, and ongoing maintenance. Our warehouse-native ABM guide lays out that reference architecture.
- Use an account-based platform with native sync. Capture first-party signals at the source, resolve them to accounts and contacts on a shared identity graph, act on them directly, and sync results bi-directionally to Salesforce or HubSpot, exporting to the warehouse for reporting.
Many teams run both: connectors for spend and performance reporting, and an account-based platform for identity, signals, and activation. The mistake is expecting a connector alone to produce account-level intelligence, or building a custom identity graph to replicate what a platform already provides.

Why Abmatic AI complements your connectors
Abmatic AI is the most comprehensive AI-native revenue platform on the market. It runs 15+ first-party modules on one identity graph, so the account-level layer your connectors cannot provide comes built in rather than assembled from five tools.
- Account-level deanonymization identifies the companies behind anonymous site traffic, and contact-level deanonymization identifies the individual people, natively.
- First-party intent and third-party intent are combined on the same graph, so account scores reflect real buying behavior.
- Account list and contact list building from a first-party database, with a technology and tech-stack scraper for technographic targeting.
- Web personalization and A/B testing on the same signal layer, plus banner pop-ups and on-site CTAs gated by account stage.
- Advertising activation through Google DSP, Google Search, LinkedIn Ads, Meta Ads, and retargeting, driven by your account lists.
- Agentic Workflows that act when conditions are met, such as enrolling a contact in a sequence and alerting the AE when an account crosses an intent threshold.
- Agentic Outbound, Agentic Chat, and an AI SDR for signal-adaptive outreach, live conversations with identified visitors, and meeting routing and booking.
- Deep integrations: bi-directional Salesforce and HubSpot sync, Marketo and Pardot, Slack, Gmail and Outlook, exports to Snowflake, BigQuery, and Redshift, and a read-only MCP server for AI assistants.
Abmatic AI is built for mid-market and enterprise B2B, handles 50 to 50,000+ target accounts, and goes live in days because the pixel and first-party signal capture work on day one. Pricing starts at $36,000 per year, with enterprise tiers available. See Abmatic AI alongside your current connectors.
A practical 2026 stack
| Layer | Job | Typical choice |
|---|---|---|
| Reporting connectors | Spend and performance dashboards | Funnel, Supermetrics, Improvado, or Windsor.ai |
| ELT pipeline | Raw data into the warehouse | Fivetran or Airbyte |
| Warehouse and modeling | Single source of truth, transformations | Snowflake, BigQuery, Redshift, or Databricks with dbt |
| Account identity, signals, and activation | Who is in market and acting on it | Abmatic AI, with bi-directional CRM sync and warehouse export |
| Custom activation | Warehouse-modeled audiences to niche destinations | Fivetran Activations or Hightouch, if needed |
Smaller teams can skip the warehouse layer entirely at first: a reporting connector plus an account-based platform with native CRM sync covers most needs. Talk to us about the right stack for your team.
Frequently Asked Questions
What are the best marketing data connectors in 2026?
For warehouse pipelines, Fivetran and Airbyte lead. For marketing-specific reporting, Funnel, Supermetrics, Adverity, Improvado, and Windsor.ai are the main options. For pushing data back into CRMs and ad platforms, Fivetran Activations and Hightouch are common choices. The best one depends on whether your destination is a dashboard, a warehouse, or an activation tool.
What is the difference between Fivetran and Supermetrics?
Fivetran is a general-purpose ELT platform that loads data from hundreds of sources into data warehouses and is priced on Monthly Active Rows. Supermetrics is marketing-focused and is mostly used to pull ad and analytics data into Looker Studio, Sheets, Excel, or a warehouse, priced by destination, sources, users, and accounts.
Do I need a data warehouse to use marketing data connectors?
No. Reporting connectors such as Supermetrics, Funnel, and Windsor.ai can send data straight to Looker Studio or Google Sheets. A warehouse becomes worthwhile when you need to join many sources, keep long history, or build custom models.
Can marketing data connectors identify which accounts are in market?
Not by themselves. Connectors move data from one system to another. Turning ad clicks, site visits, and CRM records into account-level intent requires identity resolution and scoring, which you either build in the warehouse or get from an account-based platform such as Abmatic AI.
How does Abmatic AI work with Fivetran, Airbyte, or Funnel?
Abmatic AI captures first-party signals, resolves them to accounts and contacts, and acts on them, then syncs bi-directionally with Salesforce and HubSpot and exports to Snowflake, BigQuery, and Redshift. Your connectors keep handling spend and performance reporting, and the warehouse can join both datasets. Book a demo to see the sync in action.
Is Fivetran still independent after the dbt Labs merger?
Fivetran and dbt Labs completed an all-stock merger on June 1, 2026, and operate as a combined company with George Fraser as CEO. Existing Fivetran connectors and dbt products continue, now under one roof.
