# The SegmentStream alternative built for sales-led SaaS funnels

SegmentStream combines cross-channel attribution, incrementality testing, and marginal analytics with automated budget allocation, and connects to CRMs and AI clients over MCP. Cometly is built for B2B SaaS teams whose funnel runs on booked demos, sales calls, and CRM stages, with company-level journeys and Stripe revenue tied to every campaign.

**SegmentStream:** AI-driven cross-channel attribution with incrementality testing, marginal analytics, and automated budget allocation.

## Why teams switch

### 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.

### Stripe revenue per campaign

Payments, subscriptions, trials, and refunds tied to source so you see MRR, expansion, and LTV by campaign.

### 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.

## Frequently asked questions

### Does Cometly attribute at the company level?

Yes. Account Journeys merge every contact at an account into one chronological timeline, so multi-person buying committees are attributed as one account, and revenue is credited to the ads, content, and reps that actually moved the deal.

### 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.
