What is Sphere?
Founded in 2021 and headquartered in San Francisco, Sphere provides global indirect-tax automation for technology companies. Its platform covers 190+ countries and is backed by $25.3M, including a $21M 2025 Series A.
Sphere is a global indirect-tax compliance platform for businesses selling across borders. It monitors tax obligations, supports registrations, calculates tax at checkout or through an API, and automates filing and remittance. Its AI research engine, TRAM, reads tax law and rates; tax experts review determinations while a deterministic engine applies them in real time. The product is designed to replace fragmented local-provider workflows with one operating layer for sales tax, VAT, and GST.
The platform spans nexus and threshold monitoring, registration, tax calculation, returns, remittance, input-tax recovery, and e-invoicing. Sphere offers REST APIs, prebuilt billing and accounting connections, direct lines to 130+ tax authorities, and local rails for compliance. Its breadth is strongest for digitally delivered goods, subscriptions, and global technology businesses; buyers with unusual products, complex marketplace models, or specialist local requirements should validate coverage and filing scope before purchase.
Sphere is aimed at finance, tax, and operations teams at fast-growing technology companies expanding into multiple jurisdictions. Public pricing starts at $100 per region per month for the Starter plan, including monitoring, registration, calculation up to 50,000 transactions, filing, remittance, and local integrations. Growth is custom for 10 or more regions and adds e-invoicing. Sphere says deployment can take under 24 hours and provides Slack-based support.
