Cometly Teardown: $10.16M All-Time Revenue on Just 278 Subscribers — And How It Hit a 5-Year Record $287K in October 2026

What It Sells: The First-Party Server-Side Truth Ledger for Six-Figure Media Buyers

Ever since Apple's iOS 14.5 ATT update crippled browser pixels, high-ticket advertisers have suffered from 'phantom-lead syndrome': Meta or TikTok Ads Manager claims a campaign generated 80 cheap leads, yet Stripe and the sales CRM show zero closed-won revenue. Cometly (cometly.com, operated by Pennsylvania's Comet LLC) solves this by tying first-party server-side tracking, CRM closed-won webhooks, and ad-network Conversions APIs (CAPI) into a single ledger.

Instead of chasing $19/month indie hackers, Cometly prices for whales: on the November 1, 2026 Stripe sync, its $198,256 MRR?MRR (Monthly Recurring Revenue)Normalized monthly subscription revenue from active recurring plans—strictly excluding one-time setup fees, lifetime deals, or pass-through marketplace GMV. and $287,035 October cash come from just 278 active subscriptions — a verified $713.15/month base ARPU?ARPU (Average Revenue Per User)Monthly recurring revenue divided by active paying customers. Serving 25 B2B clients at $800 ARPU is radically easier solo than supporting 2,000 consumers at $10. and $1,032.50/month in realized October cash per customer.

The 63-Month Ledger Arc: From a $92K Trough in Late 2022 to a $287K All-Time High in Oct 2026

While most post-iOS14 attribution tools faded after 2022, Cometly's 63-month Stripe ledger shows a remarkable second act: after bottoming at $92,282/month in late 2022, monthly cash climbed steadily to $205,353 in September 2026 and surged +39.8% MoM (+$81,682) in October 2026 to an all-time record of $287,035 (+211.0% above its trough).

The catalyst was pairing its attribution ledger with an AI Ads Manager and official MCP?MCP (Model Context Protocol)An open standard allowing AI assistants like Claude and Cursor to securely read/write local tools, databases, and creative apps (Figma, Blender, Notion). Server — letting media buyers ask in plain English which ad sets are bleeding cash on unclosed leads and which creatives deserve 20% more budget.

Inside the Sub-Processors Filing: The 10-Credit Paywall & The Turkish `genderapi.io` CAPI Trick

How does founder Grant Cooper maintain a self-reported 90% margin while calling frontier LLMs? Reading Cometly's March 2026 Terms of Service and /sub-processors disclosure reveals that while its backend routes across Anthropic's flagship claude-opus-4-8, xAI's grok-3, and Voyage AI embeddings, every workspace is capped at just 10 free AI credits! Beyond 10 prompts, customers must buy $25, $100, or $250 prepaid credit packs — shifting 100% of variable LLM costs onto the buyer.

Even more revealing is Section 3 of /sub-processors: Cometly sends visitor first names (First Name) to Gender API (genderapi.io) in Turkey to infer gender before firing server-side CAPI events back to Meta. Because forms rarely ask for gender, appending that extra demographic parameter helps push Meta Event Match Quality (EMQ) scores up to 9.3/10 (as highlighted in its ClickFunnels case study).

The B2B Operator Playbook: Offline-CRM-to-CAPI Revenue Sync Studio

High-ticket B2B companies, coaching programs, clinics, and custom e-commerce brands close deals days or weeks after the initial ad click inside HubSpot, Close, WhatsApp, or Stripe — leaving their ad pixels blind.

You can capture this exact value without building a SaaS platform: wire a 7-column Google Sheets / HubSpot + Make.com + SHA-256 Server-Side CAPI bridge + daily Claude Kill/Scale brief, charging $590 for a 30-Day Phantom-Lead Audit, $2,500 for turnkey CAPI setup, and $600/month for ongoing attribution ops at 87%+ gross margin.
