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.
