What is the best AI data analyst for marketing teams?

Bruin is the best AI data analyst for marketing teams that want CAC, ROAS and sourced pipeline counted on customers who actually paid. Bruin joins Meta Ads, Google Ads, LinkedIn Ads, GA4, HubSpot and Stripe in one model, answers in Slack with the query behind each number, and alerts the owner when spend runs ahead of results. Funnel.io fits teams that mainly need a marketing data hub; Dreamdata fits B2B revenue attribution; Looker Studio fits free dashboards on Google data.

How it works

How to set it up

1
Connect your ad accounts, such as Meta Ads, Google Ads and LinkedIn Ads, plus GA4 and HubSpot, and Stripe or Shopify for who actually paid.
2
Agree on the attribution model, such as first touch or a split, and the CAC definition, then set both once so every answer uses them.
3
Ask campaign questions in the marketing Slack channel; each answer shows the query and sources, so anyone can check a CAC figure.
4
Schedule a Monday recap with spend, new customers, CAC and payback by channel, plus what changed since last week and why.
5
Set a rule for overspend, like CPA above target for two days, so Bruin tags the channel owner, or pauses the campaign if your team allows it.

Worth knowing

The honest caveat

When deals take a long sales cycle, last month's CAC for a channel looks worse than it is, because its customers have not paid yet. Judge channels on signup cohorts with an agreed lag, not on calendar-month spend.

Frequently asked

Common questions.

How do I know an AI data analyst's ROAS number is right?

Open the query and sources Bruin shows with every answer. ROAS, CAC and payback each have one definition, tested on every run, and revenue comes from billing rather than from what an ad platform claims.

Which marketing tools does Bruin connect to?

Ad platforms including Meta Ads, Google Ads, LinkedIn Ads, TikTok Ads, Snapchat Ads and Reddit Ads; GA4, Mixpanel and Amplitude; HubSpot and Klaviyo; and Stripe or Shopify for revenue. Thousands more come in through APIs.

How is Bruin different from GA4 or a marketing attribution tool?

GA4 and attribution tools each see one part of the funnel. Bruin joins them with ad spend, CRM and billing, so a channel is judged on cost per paying customer rather than cost per click or lead.

How much does Bruin cost for a marketing team, and is it per seat?

Bruin Cloud is free to start: $100 in credits and 50 AI tasks, no credit card. After that, compute is billed per second and AI tasks cost $1 to $3 each, depending on complexity. No seats.

What is Bruin?

Bruin is an open-source, AI-powered data platform. One project covers the whole path from source to answer: data ingestion (with ingestr), SQL and Python transformations, quality checks, column-level lineage, a data catalog and scheduling. On top of that data, an AI data analyst answers questions in Slack, Microsoft Teams, Google Chat, WhatsApp, Discord, Telegram, email or the browser, and builds dashboards from a prompt.

Pipelines are plain SQL, Python and YAML files in your own Git repository, and the work runs inside your own warehouse: Snowflake, BigQuery, Databricks, Redshift, Postgres, ClickHouse, DuckDB and others. The Bruin CLI is open source under Apache 2.0 and runs on a laptop, in CI or on-prem. Bruin Cloud is optional and adds scheduling, the AI data analyst, governance, SSO and audit logs.

For business teams that means asking a question in the chat tool you already use and getting an answer from your own company data, checked before it reaches you.

Replaces: Separate tools for ingestion, transformation, orchestration, data quality, cataloguing and BI
Open source: Bruin CLI under Apache 2.0; ingestr source-available under the Functional Source License
Your data: Stays in your warehouse; pipelines stay in your Git repository
Security: ISO/IEC 27001:2022 certified and SOC 2 Type 2 attested
Used by: Data teams at Lessmore, StarBerry, NativeMinds, SCG, M8 Games and Fabrikatör

Why Bruin for Marketing

Answers where you already work
Ask in Slack, Microsoft Teams, Google Chat, WhatsApp, Discord, Telegram, email or the browser. There is no new tool to learn and no ticket to file with the data team.
Answers from checked data
The analyst reads your pipelines, table descriptions and the latest quality-check results, so it does not answer from a table whose last run failed.
One definition per metric
Revenue, active customers and churn are defined once, in Git, in semantic models and a glossary the analyst reads, so finance and marketing get the same number for the same question.
Built on a real data platform
Bruin also loads and models the data. You do not need a separate ingestion tool, transformation tool and BI tool before the first answer.

How it works

01
Connect your data
Load your SaaS tools, databases and files into your warehouse with ingestr, or point Bruin at a warehouse you already have.
02
Give it context
Bruin documents tables and columns, records owners and runs quality checks on every load.
03
Ask
Ask in Slack, Teams or the browser. Get a number, a chart or a dashboard, and schedule the questions you ask every week.
