Carta Startup Story: How Henry Ward Built a $7B.

This is the story of Henry Ward and Manu Kumar, who turned a coffee shop conversation about paper stock certificates into Carta, the equity management platform now trusted by more than 50,000 companies and tracking over $4.2 trillion in assets.

Henry Ward: The Founder Who Learned From Failure First

Henry Ward had a weight on his shoulders when he came to Carta. Mathematics and Computer Science graduate of the University of Michigan, Henry went to EDHEC Business School in France to pursue a Master of Science in Market Finance. His first venture was an optimization product for the retail market that Henry called Second Sight. He built it, sold it, struggled to acquire users, and then failed. In that failure was something much more valuable than a successful acquisition: intimate familiarity with a real problem nobody had solved. While raising money and attempting to issue shares for Second Sight, Henry hit the wall that thousands of startup founders had run into before him. Certificates. Paralegals updating books. Spreadsheets that became obsolete within days. The legal spend that a young startup couldn't afford. There was no single source of truth and no single way of knowing exactly what percentage each person in the company owned. The cap table: a document reflecting a startup's shareholder list, arguably the most crucial financial record, was being managed with tools that were from another century. It was all Henry could think about.

Manu Kumar: The Investor Who Became a Co-Founder

Manu Kumar wasn't what people normally think of as a co-founder. He was the founder of K9 Ventures, a Silicon Valley micro-fund that had invested in Henry's first company. He had seen Henry at work at Second Sight. He knew what Henry was capable of. When Second Sight started to fade, Manu didn't look elsewhere for another founder. He sat down with Henry for coffee, and in doing so, steered him towards the problem that had been invisible all along. Every company he invested in was doing its cap table badly. Every transaction was slower, more expensive, and more likely to contain errors. Henry had experienced this as a founder, and Manu had observed this with many companies; between the two of them, they knew all about the problem. They started eShares in July 2012, and Henry became CEO. Manu became chairman.

The Problem Nobody Thought Was Big Enough

The first hurdle wasn't the product that Henry built. It was getting investors to see that the problem was worth fixing. "Nobody believed this could ever be a big business," he later recalled. On paper, it seemed insignificant: cap table management. Certificates. Legal administration. None of these are the words that get a VC to lean in, however. Henry, though, was convinced that the space was being drastically undervalued. Underneath the cap table problem lies a gigantic, systemic problem: the plumbing of private ownership. Digitise the cap table, and you could digitise the securities. Digitising securities would enable you to track equity comp. If you could track equity comp, you could offer 409As, which every startup requires every year for tax purposes. And once you have all of these pieces, you can build an actual private stock exchange. Employees and investors could trade private company securities before the company went public. "We didn't know then it would take seven years to build the equity exchange we now call CartaX," Henry said, "But that was the initial inspiration. We always wanted to build liquidity. We had to address the cap table problem first." He began by handling paper certificates. And he charged $20 for each one he put online. This is a similar strategy used by many great fintechs. We detailed in a previous article how private equity is coming for tech. But in the world of fintech, lasting financial infrastructure begins with the simple fix for an aching inefficiency, and builds from there.

First Milestone: 100 Customers and a Network That Compounded

The first customers of eShares were sourced from Manu Kumar's network. These entrepreneurs and investors, who already had faith in Manu, were willing to try a service built by a company and a leader he endorsed. Each customer generates data, making the service more robust. Each company signing up made the service more valuable to the multitude of investors and law firms dealing with multiple companies. This was a gradual process. They started slowly and then experienced exponential growth through compounding network effects. When eShares closed its Series B round of funding for $17 million, led by Spark Capital in August 2015, it had a sufficient user base to validate the market. 409A valuations were then added as another subscription product. Fund administration followed as a natural extension to the platform. Instead of simply serving one startup at a time, it was now used by Venture Capital funds to administrate their portfolios. Additional products were added that brought customers and entrepreneurs in and discouraged people from leaving. This compounding network effect is what distinguishes the best infrastructure businesses from "normal" software. This is why, as discussed in the story on Airtable, "He Sold His First Startup at 21. Then He Spent Three Years in Silence Building Airtable", founders who build platforms rather than point solutions tend to generate the most durable businesses.

The Rebrand: From eShares to Carta

In 2017, the founders' goals were considerably bigger than digital certificates. They renamed the company. EShares was rebranded to Carta, a reference to the Magna Carta, the document that introduced fundamental private property rights to people everywhere. This was a strategic naming choice. Private property rights and personal rights were the same, as Henry would later explain in a widely-read blog post. Carta was constructing the rails that would allow people to own things in the digital economy. The name change was the company's way of communicating to the market that it was now, and forever, an OS for private ownership, not a legal workflow product.

The Funding Story: From $20 Certificates to a $7.7 Billion Valuation

Each round for Carta's growth has been further evidence of Henry's broader original vision. Series A in 2013, Series B (led by Spark Capital) in 2015, then Series C, D, and E followed. In 2021, Carta raised $500M from Silver Lake in a Series G round, bringing its valuation to $7.4B. This has cumulated in over $1.1B in total funding raised in multiple rounds. By early 2023, 95% of startups were choosing Carta as their cap table software, and network effects were so great that it was becoming the infrastructure of the startup world. There were over 50K companies, 8.5K investment funds, and 2.5M equity holders on the platform, and assets tracked topped $4.2T. Henry Ward, after being told that no one believed cap tables could be a big business, was now leading what would arguably become the most important infrastructure for venture capital. To achieve this scale and build trust requires a similar level of discipline that security companies use to protect data. As we examined in our piece on cybersecurity and data privacy in business, those who hold the most sensitive information bear the greatest responsibility to protect it. This realization would become especially important to Carta.

CartaX: The Ambition That Went Too Far

It had always seemed to Henry that building the infrastructure to create equity was ultimately building liquidity. If Carta controlled the cap tables for tens of thousands of companies, then Carta was positioned to be a liquid trading market for those companies. In 2020, Carta launched CartaX, a private stock exchange where secondary transactions of stock could take place. The idea was powerful. Employees had years of waiting for a liquidity event and could sell some shares along the way. Then, in January 2024, a prominent startup founder accused Carta of what caused this crisis: Carta employees had allegedly accessed non-public cap table data without the explicit authorization of the customer. That information was allegedly used to solicit shareholders to sell their stock via CartaX. The sensitive data customers entrusted toCarta was leveraged for Carta's own revenue generation. In the startup world, the initial response was thunderous. Startups and investors argued openly about whether or not to take their cap tables off the platform, and the line, "this may be the end of Carta as the trusted platform for startups," was heard repeatedly. Henry reacted fast and shut down CartaX entirely. He published an apology, owning up to a major mistake, and that trust is everything Carta had built. He made no attempts to downplay the incident. The response was raw, sincere, and frank. Customers remained; some departed. This type of trust crisis is hardly uncommon in the startup community. As we discussed in the story on Tines, managing extremely sensitive data necessitates a greater level of accountability than merely delivering a good product. The way you perform when trust is fractured reveals the soul of the organization.

The Lawsuits and a Leader Under Scrutiny

CartaX was hardly the only chapter that proved challenging. An array of lawsuits would land in 2023 and 2024, where female former employees claim a culture of retaliation existed-evidence from these lawsuits painted a picture of a CEO quick to react aggressively to internal critique. Henry would deny many of the portrayals. Still, the lawsuits served as a constant reminder that the very traits required to build something extraordinary can lead to blind spots when managing the organization born of that building. Truly challenging years for Carta's reputation, 2023 through 2025 are periods that growth metrics alone can't represent, when customers continued to use the product, and customers continued to expand their relationships with the company, but the trust element with both employees and customers would undergo serious stress.

Pivot to AI and the Road Back

The story now turned toward a 180-degree shift. By the end of 2024 and in early 2025, Henry repositioned the company completely. The launch of CartaX ceased, and the business laser-focused its attention on its primary platform and the use of artificial intelligence. Carta started to market itself as the AI-driven ERP for private markets. Not just a cap table solution but a fully fledged private capital operating system. The idea was to eliminate all the administrative, compliance, and financial reporting that lawyers, CFO's, and fund admins were all paying for in PE. Tax was a good early example of it. In April 2025, Henry proudly posted that Carta delivered 2084 returns by April 15th that year, nearly double the number from the year before, and nearly 6x the number of 2024 returns. This was done through automating and not optimizing the entire tax process. Morgan Stanley, one of the leading institutions for private capital, increased its partnership with Carta in September 2025-a sign that the firm clearly believed in Carta as critical infrastructure in the space. All sectors today are going through similar, AI-driven re-invention processes. Just like we discussed in our article on how AI has altered remote working, those firms that build AI into their primary workflow do not just become more efficient; they transform the actual offering and function of their products.

Where Carta Stands in 2026

Currently, Carta serves 50,000+ companies, 8,500 investment funds, and 2.5 million equity holders. The platform is responsible for tracking more than $4.2 trillion in assets. From cap table management, 409A valuations, fund administration, equity compensation, and tax & compliance services, the range of services offered now also includes an evolving AI layer. Carta is a company with approximately 1,600 employees in its offices in San Francisco, New York, Seattle, London, and all over the world. Henry Ward remains CEO, and Manu Kumar is the chairman. While an IPO has been floated, it is yet to be materialized, and the company continues to expand its enterprise customer list and its foothold in the venture capital and private equity industries. Valuation of $7.4B from the Series G round in 2021 has not been updated in the company; however, it is among the largest private fintech companies globally.

What Their Story Teaches Every Founder

Here are three lessons from the Carta story. First, personal pain as a product insight. Henry did not spend time identifying a gap in the cap table software market. He stumbled into the gap while building his first company. That pain and frustration he personally experienced in the problem drove him forward when investors told him that the market was too small. Second, the non-traditional co-founder. Manu Kumar was Henry's investor before becoming Henry's co-founder. The right co-founder is whoever can fill in the skills you are missing without any other requirements. Third, the cost of overreach. CartaX was a compelling vision, but it was built on top of something customers already believed and trusted. When that trust was damaged, it caused more damage to Carta than any loss of revenue could have. If a company holds confidential information, that business carries a whole different level of responsibility. Carta learned this the hard way. Running a company also involves asking for money in the right way. As we discussed in our article on startup bootstrapping and fundraising strategy, a great founder asks for capital in a way that simultaneously maintains the trust of their investors, customers, and employees.

Final Thought: The Paper Certificate That Became $4.2 Trillion

In 2012, Henry Ward would have charged you 20 to put your paper stock certificate on a digital line: today, that system tracks the ownership of more than 50,000 businesses totaling more than 4.2 trillion in value. There wasn't one straight line from that initial certificate to Carta as we know it, but there was the initial failing business; the coffee shop conversation to set the world back on its axis; years of teaching the world what they didn't know about this enormous market; the billion-dollar conviction in an invisible private stock market; the collapse caused by a breach of trust, and the subsequent rebuilding that still goes on today, each piece managed by Henry Ward. A cap table had never been an artifact of just numbers, but of ownership, of sacrifice, of right. It was a problem worth trying to fix properly, and Carta is still trying.
