In the world of registered agents, age is a credential. CSC was founded in 1899. CT Corporation dates to 1892. Paracorp has been in Sacramento since 1977. These are companies that measure their track records in decades, sometimes in centuries.
Then there is ZenBusiness Inc. — founded in 2015, valued at $1.7 billion by 2021, and now listed as a designated registered agent under California Corporations Code Section 1505 with a Sacramento office at 2520 Venture Oaks Way, Suite 120. It is the newest major entrant on the California registered agent list, and by several measures, the most heavily funded.
This is the story of how a tech startup built for entrepreneurs became one of Sacramento’s registered agents — and what it means for the local registered agent landscape.
The Business Formation Play
ZenBusiness did not start as a registered agent company. It started as a business formation platform — a website where first-time entrepreneurs could form an LLC or corporation without hiring a lawyer. The pitch was simple: type in your business name, pick your state, pay $0 plus the state filing fee, and ZenBusiness handles the paperwork.
The model worked. By offering business formation at zero cost (or nearly zero cost), ZenBusiness captured an enormous volume of first-time business owners. Those business owners then needed ongoing services: annual report filing, compliance monitoring, operating agreements, EIN numbers, and — critically — a registered agent to accept legal documents on their behalf.
The registered agent service was the natural upsell. Form your LLC through ZenBusiness for free, and for $99 per year (first year), ZenBusiness will also be your registered agent. The customer is already in the platform, the checkout flow is seamless, and the lifetime value of the customer increases significantly.
This is the ZenBusiness growth engine: free formation captures the customer, and paid services like registered agent, compliance monitoring, and the $199-per-year Worry-Free Compliance Guarantee generate recurring revenue.
Five Rounds to Unicorn
The funding timeline tells the growth story:
May 2016 — $50K accelerator. ZenBusiness is an idea with a small team in Austin.
February 2018 — $4.5M seed round led by Lerer Hippeau, a New York venture firm known for early-stage consumer and SMB investments. This capital builds the initial platform.
September 2019 — $15M Series A led by Greycroft. ZenBusiness is gaining traction in the competitive business formation market, going up against LegalZoom, Incfile, and dozens of smaller competitors.
November 2020 — $55M Series B led by Cathay Innovation. The pandemic has created a surge in new business formations as millions of Americans lose jobs and turn to entrepreneurship. ZenBusiness rides this wave hard, adding thousands of customers per month.
November 2021 — $200M Series C led by SoftBank, with participation from Mark Cuban. This is the round that values ZenBusiness at $1.7 billion and makes it an Austin unicorn. The capital is earmarked for expansion — more states, more services, more customers.
Total raised: $275 million.
By 2024, ZenBusiness reports $150 million in annual revenue, up from $115 million in 2023. The company has formed over 850,000 businesses and employs approximately 300 people.
The Mark Cuban Factor
When Mark Cuban joined ZenBusiness as an investor and spokesperson in 2021, it gave the company something no other registered agent has: a celebrity endorsement with genuine small business credibility. Cuban, known for Shark Tank and his ownership of the Dallas Mavericks, is one of the most recognizable business figures in America.
Cuban does not just lend his name. He has appeared at SXSW events alongside SBA Administrator Isabella Casillas Guzman on behalf of ZenBusiness, and he uses ZenBusiness tools with his own companies. For the first-time entrepreneur forming an LLC, seeing Mark Cuban’s name attached to ZenBusiness carries weight that no amount of advertising can replicate.
No one at CSC, CT Corporation, or Paracorp has Mark Cuban on speed dial.
Why Sacramento
ZenBusiness is headquartered in Austin, Texas, at 5511 Parkcrest Drive, Suite 103. So why does a Texas tech startup have a registered agent office in Sacramento?
The answer is California Corporations Code Section 1505. To serve as a designated agent for service of process in California, a company must maintain a physical office in the state where authorized personnel can accept legal documents during business hours. Sacramento is the logical choice: it is the state capital, home to the California Secretary of State’s office, and the city where most major registered agents maintain their California operations.
ZenBusiness chose 2520 Venture Oaks Way — a Class A office building in the South Natomas submarket managed by Basin Street Properties. The location is strategic: it sits just 4.7 miles from the State Capitol, within one mile of both I-5 and I-80, and in the same corridor as CSC (0.5 miles away) and Paracorp (0.6 miles away). The building itself is an 82,153-square-foot, four-story structure with amenities including a fitness center, conference facilities, tenant lounge, EV charging stations, and landscaped grounds with water fountains.
Suite 120 is on the ground floor. A wall-mounted plaque with a copper accent strip identifies the office. The lobby features a digital touchscreen directory, stone flooring, leather seating, and modern art — consistent with the Class A designation.
Three Acquisitions
In addition to organic growth, ZenBusiness has made three acquisitions:
• Two undisclosed acquisitions in 2020, during the peak of pandemic-driven business formation demand.
• Ureeka in September 2022 — a professional community platform founded in 2019 in Burlingame, California, that connected small businesses with mentorship and expertise.
The Ureeka acquisition is notable because it signals ZenBusiness’s ambition to be more than a filing service. They want to be the platform where entrepreneurs form their business, manage their compliance, access mentorship, and eventually handle their banking (through ZenBusiness Money, their fintech product).
What This Means for the Sacramento Registered Agent Landscape
ZenBusiness’s arrival adds a new dimension to Sacramento’s registered agent ecosystem. The existing agents break down into clear categories:
Legacy corporate agents — CSC (1899) and CT Corporation (1892) — serve Fortune 500 companies and large enterprises. They have institutional track records measured in centuries.
Independent local agents — Paracorp (1977) — serve mid-market businesses with an employee-owned, Sacramento-headquartered model.
Online-first agents — Northwest Registered Agent (1998) — serve privacy-conscious small business owners with straightforward pricing.
ZenBusiness occupies a new category: the venture-backed tech platform agent. With $275 million in funding, a $1.7 billion valuation, and 850,000+ businesses formed, ZenBusiness brings Silicon Valley-scale resources to a Sacramento office. Their customers are overwhelmingly first-time LLC owners who formed through the ZenBusiness platform — a demographic that barely existed as a registered agent customer base 10 years ago.
The PBC Angle
ZenBusiness is structured as a Public Benefit Corporation (PBC), with a stated public benefit of “promoting entrepreneurship by providing accessible products and responsive support.” This is an unusual structure for a registered agent. Most agents are traditional corporations (CSC, CT) or employee-owned (Paracorp). The PBC designation means ZenBusiness is legally committed to considering its stated public benefit alongside shareholder returns — a structure that connects to the broader social enterprise movement.
Whether the PBC structure translates into meaningfully different service at the Sacramento office is debatable. For process servers delivering documents to Suite 120, the corporate structure is irrelevant to the service acceptance procedure. But for business owners choosing an agent, the PBC status is a data point worth noting.
What Process Servers Need to Know
Regardless of the funding rounds, the celebrity investors, and the unicorn valuation, the practical reality for process servers is straightforward:
ZenBusiness Inc. maintains a staffed office at 2520 Venture Oaks Way, Suite 120, Sacramento, CA 95833. They accept service of process Monday through Friday, 9:00 AM to 5:00 PM. The building has free parking, a ground-floor suite, and is located in the same Natomas corridor as CSC and Paracorp.
We serve this office regularly. Whether the entity you need to serve is a one-person LLC that formed through ZenBusiness last month or a larger company that chose ZenBusiness as its agent, the process is the same: our server delivers documents to Suite 120, obtains acceptance, and provides you with a court-ready proof of service.
Standard Service (10 business days): $99
Expedited Service (3 business days): $150
