Why teams switch
Why B2B SaaS teams choose Cometly over Windsor.ai.
The pattern we hear from operators evaluating both: they need attribution that understands a SaaS funnel, integrates with the CRM they already run, and pushes deal-stage events back to Meta, Google, and LinkedIn with high match quality.
Company-level attribution built in
Account Journeys roll every contact at an account into one timeline, so buying committees are attributed as one account and channels get credit for moving the whole deal.
Demos, calls, and CRM stages as first-class events
Booked demos, attended calls, MQL, SQL, opportunity, and closed-won flow in natively from HubSpot, Salesforce, Close, Attio, HighLevel, Pipedrive, and Calendly, with attribution written back to the records.
Conversion API with 9.3 / 10 match quality
14+ parameters per event so Meta, Google, LinkedIn, and TikTok optimize toward demos and closed-won deals.

When Windsor.ai is the right fit
If you have analysts or a data team who want raw marketing data from hundreds of sources flowing into Looker Studio, BigQuery, or Snowflake, and you want to build your own attribution and reporting on top, Windsor.ai is a strong, affordable data layer. Cometly is the better match when you want attribution delivered as a finished product: first-party tracking, company-level journeys, CRM write-back, Stripe revenue by campaign, and Conversion API, without building the pipeline yourself.
“Better ad targeting. Better funnel insights. Better CPA control. We've scaled our ad spend 40% since implementing Cometly and it's definitely one of the tools in our tech stack that's given us the confidence to do so.”

FAQ
Cometly vs Windsor.ai.
The questions B2B SaaS teams ask most when evaluating both platforms.
Talk to salesCan Cometly feed my warehouse and BI tools too?
Yes. Cometly writes a modeled attribution table into Snowflake, BigQuery, or Redshift, exposes a REST API and webhooks, and syncs attribution fields onto HubSpot and Salesforce records, so Looker, Tableau, or Metabase can read the same numbers your dashboards show.
Is Cometly only for B2B SaaS?
Cometly was built ground-up for B2B SaaS. That means multi-touch attribution across long sales cycles, deep HubSpot and Salesforce integration, Stripe revenue tied to ad sources, and Conversion API sync of MQL, SQL, and deal events.
How long does implementation take?
Most teams are live with validated channel-level pipeline within 1 to 2 weeks. The first sales cycle (typically 60 to 90 days for B2B SaaS) is when you'll have full closed-won, CAC, payback, and LTV data attributed by source.
Can I keep my CRM as the source of truth?
Yes. Cometly pulls lifecycle stages, deals, and revenue from HubSpot, Salesforce, Close, Attio, and others, and never overwrites them. Your CRM stays the system of record; Cometly adds the attribution layer underneath.
What does Cometly cost?
Cometly ships two plans: Core (everything a B2B SaaS revenue team needs to attribute pipeline and revenue) and Enterprise (warehouse export, Salesforce custom triggers, advanced scale, MCP, and dedicated support). Pricing is usage-based and tailored to your existing sessions and ad spend. See /pricing for the structure and request-quote flow.
