1Lookup Teardown: $508.6K/Month on Just 749 Subscribers — And Why Its Asking Price Jumped 10x from $1M to $10M

What It Sells: The Pre-Send Hygiene & TCPA Shield for Outbound Teams and AI Agents

Outbound sales agencies and B2B growth teams face two existential threats: burning their primary domain reputation on hard-bounced emails (>3% bounce rate triggers Google/Microsoft blocks) and dialing numbers on the US National Do Not Call (DNC) registry or known TCPA litigator lists ($500–$1,500 statutory damages per call). 1Lookup (1lookup.io) acts as a 76-in-1 real-time hygiene gate — verifying live carrier HLR status, line type (mobile vs. landline/VoIP), SMTP validity, and DNC flags in milliseconds.

Crucially, 1Lookup shipped a zero-install hosted Model Context Protocol server (app.1lookup.io/api/mcp via OAuth 2.1). As companies deploy autonomous AI SDR agents in Claude, Cursor, and n8n, those agents ping 1Lookup automatically before every outbound touchpoint — turning autonomous AI workflows into 24/7 credit-burning machines.

The Ledger Audit: How 749 Subscribers Generate 1.82x–1.86x More Cash Than Base MRR

On the November 1, 2026 Stripe sync, 1Lookup reports $272,886 in MRR across 749 active subscriptions ($364.33/mo 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.), yet rolling 30-day cash is $495,384 ($661.39/sub, 1.82x base MRR) and full-month October 2026 hit $508,588 ($679.02/sub — 1.86x base MRR!). Where does that extra $222,000–$235,700/month come from?

Two pricing mechanics explain the gap. First, the 1x–86x credit multiplier: paid Starter plans begin at '$99/mo for 20,000 credits' ($0.005 per basic check, with unused subscription credits rolling over for up to 3 months), but while basic email/phone checks cost 1 credit, live HLR carrier checks burn 5 credits, Skip Trace and DNC Phone Scrub burn 10 credits, Mobile Finder burns 40 credits, B2B Contact Append burns 75 credits, and Audience Intelligence burns 86 credits per call. Second, threshold auto-recharge: whenever a workspace drops to 20 credits or fewer, 1Lookup automatically renews the plan on file (sweetened with a +10% credit bonus).

Cost Structure & Legal Armor: Why Net Margin Is 40% and Liability Is Capped at $100

Unlike pure SaaS wrappers with 90% gross margins, founder Robby Frank self-reports a 40% net margin. Because 1Lookup aggregates live telco HLR pings and upstream identity graphs, roughly 60% of revenue goes to wholesale data providers and payment processing.

Its legal architecture (1lookup.io/terms, operated via Delaware's 1Lookup Inc. and Wyoming's Momentum Labs) is equally instructive: Section 5.3 authorizes immediate full-plan billing without notice if a user creates duplicate accounts to abuse the 7-day free trial; Section 9 explicitly disclaims Fair Credit Reporting Act (FCRA) consumer reporting agency status; and Sections 17–18 cap total liability at the greater of $100 or 12 months of fees, insulating the company from downstream TCPA class-action pass-through claims.

The B2B Operator Playbook: Launch a Pre-Ingest CRM Hygiene & TCPA Firewall Studio

Independent operators should never build a consumer people-search site (high regulatory risk and 60% wholesale data COGS). Instead, package 1Lookup's 1-credit verification API + Claude Sonnet 4.5 ICP scoring into a turnkey 'CRM Pre-Ingest Hygiene & TCPA Firewall' for B2B agencies and exporters.

Charge $490 for a 10,000-record Dead-Lead & DNC Audit Wedge, convert clients into a $1,500 turnkey Make.com/HubSpot firewall setup, and lock in $500/month ongoing hygiene retainers at 84%+ gross margin.
