What our Census reverse ETL setup includes

Reverse ETL consultants who model the data once in your warehouse, sync it with a write rule for every field and check each sync for rejected records.

  • Models for activation

    Customer, account and event models in Snowflake or BigQuery, built with dbt, with one row per record you sync.

  • Activation syncs

    Traits like plan, usage, lifetime value and churn risk synced to your CRM and messaging tools, with matching keys and a write rule for each field. See what reverse ETL is.

  • Careful CRM writes

    Accounts matched before anything is written, API limits respected and rep-entered fields never overwritten. See reverse ETL to Salesforce.

  • Audiences for ads and messaging

    Segments sent to Google Ads, Meta, Braze and Customer.io and refreshed on a schedule. See warehouse audiences.

  • Checks after the move

    Census syncs already moved to Fivetran Activations checked against the source, so nothing silently stopped in the move.

  • Sync checks and alerts

    Every sync monitored for failed and rejected records, with results compared against the source.

Ask for a segment in plain English, then sync it where it is needed

With your warehouse connected to Claude over MCP, your team describes the segment it needs, AI drafts it on your models with real counts, and a person approves it before an activation sync sends it out.

  • Build a segment of accounts with rising usage and no open opportunity in Salesforce.. Drafts the segment on your models.
  • Which activation syncs rejected records this week, and why?. Reads activation sync logs.
  • How many Salesforce accounts are missing a usage score?. Queries the warehouse over MCP.
  • Your warehouse over MCP

    Snowflake or BigQuery connected to Claude under a read-only role, so every segment idea starts from real counts.

  • Approval before sync

    AI drafts the segment; a person reviews its definition and size before anything reaches a destination.

  • Scores AI can explain

    Lead and churn scores modelled in the warehouse, so AI can say why an account scored high.

  • Sync alerts

    Agents that flag failed syncs and rising rejection rates before a sales team works from a short list.

With every implementation

  • Yours after handover

    The MCP access, the agents and the docs live in your own accounts. Your team runs it all with AI, without depending on us.

  • No retainer needed

    A one-time setup at a fixed price. There is no monthly retainer to keep it running, so your costs go down over time.

  • Right from day one

    Anyone can set up a tool with AI, but it's only as good as what the AI guesses. We know what works from 74+ implementations.

  • Free martech AI agent

    Every implementation includes it: slash commands and skills that run your whole stack in Claude Code.

Who our Census reverse ETL setup is for

Most teams come to us at one of four points, and the scope is written for yours before any work starts.

Not the right fit without a warehouse and clean models. Start with Snowflake or BigQuery if you are not there yet.

  • Sales needs product data

    Usage, plan and billing data in Salesforce or HubSpot, where reps work. See product data in HubSpot.

  • Already on Fivetran

    You load data with Fivetran, so activating it from the same platform keeps one vendor and one bill.

  • Census customers after the move

    Your syncs moved to Fivetran Activations. We check they still do exactly what they did.

  • Choosing a reverse ETL tool

    Comparing Census with Hightouch or a CDP. See Hightouch vs Census and reverse ETL tools.

Census with the rest of your stack

Reverse ETL connects the warehouse to everything else. We set up both ends and decide which system owns each field.

  • Warehouse and dbt

    Activation syncs read tested models from Snowflake or BigQuery, built with dbt.

  • CRM

    Salesforce and HubSpot updated with product and billing traits.

  • Lifecycle messaging

    Braze and Customer.io receiving audiences and traits for journeys.

  • Ad platforms

    Customer audiences sent to Google Ads and Meta, with match rates checked.

  • Loading

    Fivetran connectors bringing the source data in, on the same platform as the activation syncs.

What's not included

So the fixed price covers exactly what we build, and nothing comes as a surprise later.

  • Your Fivetran plan

    Activations are billed by Fivetran under your plan. We help you sync only what each tool needs.

  • Running campaigns

    We set up segments and syncs. Running the campaigns that use them is not part of this.

  • Warehouse costs

    Queries the syncs run on Snowflake or BigQuery are billed to your account. We keep them incremental.

Sound familiar?

  • Sales asks for usage data in the CRM.

    It sits in the warehouse, out of reach.

  • A sync overwrote fields reps typed.

    And nobody noticed for a week.

  • Rejected records pile up.

    So segments are smaller than they look.

  • Census moved into Fivetran.

    And nobody has checked the syncs since.

We model data once in your warehouse, sync it with write rules for every field, check every sync for rejected records, and make sure the move to Fivetran Activations left nothing behind.

“Faizur helped us transfer Google Analytics conversion events to Google Ads via Segment. We set that up within two or three weeks. Now we have a clear vision of our conversions and we could optimize our campaigns like this. Because if your tracking is not on point, you can't really improve your Google Ads performance.”

Census reverse ETL questions, answered

Something else on your mind? Email hello@martechdevs.com or book a free call.

Is Census now Fivetran Activations?

Yes. Fivetran bought Census in 2025, and Census became Fivetran Activations, open to all Fivetran users since early 2026. What Census called a sync is now an activation sync.

What is reverse ETL?

Copying data from your warehouse back into the tools your teams use, like Salesforce, HubSpot, Braze or ad platforms, so they act on the same data your reports use. See what reverse ETL is.

Census or Hightouch?

Both sync warehouse data to your tools well. Census fits teams already on Fivetran; Hightouch leans into marketer audiences and AI decisioning. See Hightouch vs Census.

How much does a Census implementation cost?

Growth is $12,150 (25% off $16,200), live in 12 weeks, at a fixed price with no hourly billing. Eligible startups get 40% off the list price instead. More brands, markets or a migration from another tool make it a custom plan, priced before work starts. Activations are billed by Fivetran under your plan, and warehouse usage by your warehouse vendor. See the fixed price packages.

Do we need dbt for Census?

It helps a lot. Activation syncs read warehouse models, and dbt keeps those models tested, so a broken source fails a test instead of writing bad data into Salesforce.

Can Census write to Salesforce safely?

Yes, with the right rules. We match accounts before writing, respect API limits, write only the fields the warehouse owns and never overwrite what reps entered. See reverse ETL to Salesforce.

How long does a Census setup take?

Growth goes live in 12 weeks, or 6 weeks on super fast. Most of the time goes into field ownership and checking each destination.

Who owns the setup?

You do. The Fivetran account, models and syncs stay in your name, and we work through access you can remove at any time.

What happens after launch?

Growth includes 90 days of support after handover, up to 30 hours. It covers fixes, questions and new syncs or segments. After that your team runs it with the docs and your martech AI agent, or keeps us on a retainer from $1,980 a month.
