# Carbon > Carbon is a lead platform for paid traffic. Marketing teams, agencies and lead-gen companies send ad clicks to fast, mobile-first lead journeys, A/B test every question, and optimize for qualified leads instead of form fills. Qualified leads can be sold to contractors and other buyers, exclusive or shared, with prepaid credit. Carbon is in private beta. Teams request access at https://carbonleadplatform.com/beta. There is no public self-serve sign-up. ## What Carbon does - Journeys: fast, mobile-first lead journeys that give visitors a real answer first (an instant local estimate, a rate range, a case check), then capture contact details with consent and a phone code. - Experiments: A/B test any single question (wording, answer choices, input type, order, helper text) or swap a whole part of the journey. The goal is qualified leads per visitor, revenue per visitor or booked jobs per visitor, with guardrails. A person always promotes the winner. - Calculators: reusable pricing recipes (size × area price × answer multipliers + add-ons) with area prices set by ZIP prefix and checked against real final job prices. - Lead quality: duplicate (90 days), bad-number and bot checks before sale; a consent record (exact wording, page snapshot, time, device, IP, journey version, phone confirmation) on every lead. - Agencies: one workspace per client, reporting, and white label on Enterprise. ## How buyers (contractors, agents, firms) buy leads - Buyers are invited by text, sign in with a phone code (no password or app), and set their service area, job types and daily limit. - They prepay credit and can turn on auto top-up (for example, add $500 when the balance drops under $100). - When a lead matches, they get a text. Before buying they see the job, area, timeline, home details and the estimate the homeowner saw; the name and phone number unlock after purchase. - Leads are sold exclusive (one buyer) or shared (up to 4 buyers, set per workspace). Once anyone buys shared, exclusive is no longer offered. - Three delivery modes: marketplace (browse and buy), instant offer (the best match has 5 minutes to accept, then it moves on), auto-deliver (bought automatically within area and daily budget). - Bad leads can be disputed within 72 hours; valid disputes are credited back. Buyers report booked, won and final price, which feeds lead scoring and calculator prices. - Details: https://carbonleadplatform.com/contractors ## Pricing - Starter: $199/month billed monthly, or $129/month billed yearly ($1,548/year). 500 leads a month; $0.25 per extra lead; 1 workspace; Journeys and calculators; Lead quality and consent records. - Growth: $999/month billed monthly, or $699/month billed yearly ($8,388/year). 10,000 leads a month; $0.01 per extra lead; 5 workspaces; Everything in Starter; A/B testing on every question; Contractor marketplace and credit. - Enterprise: contact sales.
