Sphere, a tax software vendor founded by Nicholas Rudder in 2023, has successfully raised $21 million in a Series A funding round led by the venture capital firm a16z. The funding will allow Sphere to accelerate development of its market-leading community engagement platform. This platform is meant to help these growing companies to stay tax compliant as they are going borderless. Represented in this funding round are Y Combinator (YC) and Felicis Ventures.
Sphere offers a truly distinctive approach to shift the burden away from tax compliance and make it much more intuitive. It accomplishes this by leveraging its proprietary AI-driven model engine, TRAM (Tax Review and Assessment Model). This new, sophisticated tool compiles and curates tax rules from every jurisdiction. It gives the software the authority to create accurate tax conclusions for companies expanding across multiple states.
The potential of the software goes far beyond basic tax calculations. It is directly integrated with more than 100 global tax authorities, allowing businesses to register, collect, and remit sales taxes seamlessly across multiple tax jurisdictions. Sphere enables automated generation of tax returns and submits, minimizing the burden for companies desiring to comply with local tax laws and regulations. Sphere performs automatic refunds to customers’ bank accounts via debit to the customers’ tax return. It has been widely reported that it is responsible for remitting payments to tax authorities.
Rudder claimed the efficiency of Sphere’s product, noting that it can be spun up in less than 24 hours. He noted, “We help companies collect tax on customer transactions.” This is especially valuable for companies looking to understand and operate in the increasingly complicated world of global tax.
During its two years in stealth mode before launching, Sphere meticulously developed a system that minimizes reliance on third-party consulting firms. According to Rudder, “Whereas both legacy players and many of the more recent venture-backed startup competitors often hand customers off to third-party consulting firms to manage certain geographies, Sphere took the time to build integrations into local rails plus AI automations that allow it to facilitate the entire sales tax compliance process completely end-to-end.”
Rudder emphasized Sphere’s focus on becoming an essential tool for finance teams taking the plunge into new/global markets. “I want this product to be the indispensable tool that finance teams look to when they want to expand into a new market,” he stated. He further elaborated on the necessity of comprehensive compliance, saying, “Not just for indirect tax, but for every form of transactional compliance they may not even realize they’re exposed to.”
The company’s client roster includes notable names such as Lovable, Replit, and ElevenLabs, which illustrates its growing influence in the tax software sector. What makes Sphere unique in this space is that we automate a company’s registration, calculation, filing and remittance obligations. It’s a smart move to address gaps their competitors, like Stripe, leave exposed.
Rudder also pointed out that marketplaces face unique challenges regarding tax liabilities: “Marketplaces are liable for tax on their entire GMV (gross merchandise value) not just their take rate, so every new country meant a maze of registrations, filings, deadlines, and risk.” This unfortunate situation is an example of why there’s a huge need for more sophisticated solutions, such as Sphere, to help streamline these processes.
Andrusko from a16z commented on Sphere’s innovative approach, stating, “When we met a16z and heard what they’d done for similar companies in the compliance and fintech space, we knew they were the right partner.” This collaboration holds great potential to continue to improve Sphere’s capabilities and increase Sphere’s footprint in the global market.
