When Index and Bessemer backed Ryft in 2024, they expected a longer hold. A war, a disrupted fundraise, and an AI security land grab turned a seed check into one of the fastest exits in enterprise AI infrastructure history.
When Index Ventures and Bessemer Venture Partners wrote Ryft an $8 million seed check in 2024, the expectation was a five-to-seven-year hold on a company building data infrastructure for AI agents. Less than two years later, Cyera has acquired the 15-person startup for an estimated $100 million to $130 million. That is a 12-to-16-times return on a bet that barely had time to breathe.
The deal was not planned as an exit. "We were not planning to sell and were not actively seeking a buyer," Ryft chief executive Yossi Reitblat told Calcalist. "We had strong momentum, but Cyera approached us before a significant fundraising round. The war disrupted that process." Reitblat and Cyera co-founder Tamar Bar-Ilan had served together in Israel's Unit 8200 intelligence corps. Bar-Ilan flew to Israel, and conversations that began as partnership talks became acquisition negotiations — happening, as Reitblat put it, while they were running to shelters.
The war in Gaza, which began in October 2023, is not the story's main character. But it is the accelerant. Ryft was preparing for a Series A. The war froze that process and opened a window Cyera moved through. The estimated price — $100 million to $130 million on $8 million raised — reflects the strategic premium Cyera paid for speed, talent, and a product it did not want to build from scratch.
The problem Cyera is buying its way into
AI agents are becoming a permanent part of enterprise infrastructure. They read data, write data, authorize transactions, and hand off tasks to other agents. Traditional data security tools were not built for actors that are neither fully human nor fully automated — entities that accumulate permissions across dozens of systems and operate at speeds no human security team can monitor in real time.
Cyera, valued at $9 billion after a $400 million Series F in January 2026, has built its business on data security posture management — discovering where sensitive data lives, who can access it, and how it is exposed. The addition of Ryft extends that capability to the layer where AI agents actually interact with data: the authorization decisions, the access patterns, the data trails that exist only because an agent touched something.
"The value of a company is not measured by headcount or the amount it has raised," said Yonatan Itai, Cyera's co-founder and vice president of research and development, in comments to Tech Funding News. "Ryft brings deep technological expertise in a highly relevant area, solving one of the most critical challenges in enabling secure AI adoption. This is a domain we aimed to accelerate over the coming year, and speed to market was essential."
Ryft's platform automatically analyzes data access across an organization — for both human users and AI agents — and automates authorization, classification, and optimization. Its managed layer sits on top of an open-source standard for modern data lakes, handling compliance, disaster recovery, and governance without locking customers into a single vendor. Customers include Sonos, Unity, and Voodoo, according to Calcalist.
Cyera's own blog, published when it was named a Leader in Forrester's Sensitive Data Discovery and Classification report in April 2026, frames the problem directly: "AI changes what 'good' looks like. Data is constantly moving across SaaS, cloud, and on-prem. Access changes fast. New apps, pipelines, third parties, and agents show up every day. Soon, it will be every minute. A point-in-time inventory is not enough." The post describes a product called Access Trail that tracks every human and AI interaction with sensitive data — exactly the visibility gap Ryft was built to close.
What the math means
The Ryft return multiple is unusual even by the standards of a frothy AI infrastructure market. A 12-to-16-times gross return on a seed deal closing in under 24 months is rare in enterprise software; it is nearly unheard of in a category — agentic data governance — that did not exist when Ryft was founded in 2024.
Index Ventures and Bessemer Venture Partners co-led the seed round, with participation from members of the Wiz founding team and executives from Zscaler, CrowdStrike, Confluent, and Cisco, according to Tech Funding News. Ryft employed approximately 15 people at the time of acquisition, most of them based in Israel. Reitblat will now lead Cyera's AI security division.
Cyera, for its part, has been among the fastest-moving companies in data security. This acquisition is its fourth in five years, following purchases of Trail Security for $162 million in 2024, and two others the company has not disclosed publicly. Total funding raised exceeds $1.7 billion since the company's founding in 2021. In January 2026 alone, Cyera closed $400 million at a $9 billion valuation — tripling its valuation in a single year.
Cyera has also set a publicly stated target of $1 billion in annual recurring revenue within the next year, more than tripling current levels, according to Tech Funding News. Whether it can execute to that pace is an open question; the company has not disclosed its current ARR.
The market signal
Every acquisition is a data point. This one says several things at once.
First, the governance layer for AI agents is not theoretical. Enterprises are deploying agents that touch sensitive data, and the tooling to track those interactions — to see what the agent saw, what it did, where it sent the data — is becoming a required purchase, not a nice-to-have.
Second, the consolidation is happening faster than most observers expected. Ryft had $8 million and 15 employees. It was not a mature company with a long sales cycle. It was a point solution built for a specific problem, and Cyera decided it was cheaper to buy that solution than to build it internally over the next 18 months.
Third, the war in Israel continues to shape which Israeli technology companies can raise money on US terms — and which become acquisition targets instead. Reitblat's account of the deal being negotiated while running to shelters is not marketing language. It is a description of how external shocks can restructure a company's capital trajectory in a single week.
For founders in the agentic data governance space, the message is mixed. Build too slowly and a company like Cyera buys your competitor and locks up the enterprise relationships. Build too fast and you need the kind of capital that a war can interrupt. For enterprise buyers still improvising their way through AI agent security, the message is simpler: the window for choosing your preferred vendor is narrowing.
What happens next depends on whether Cyera can actually integrate Ryft's technology into a coherent product — and whether that product can retain the startup's customers, who chose Ryft specifically because it was not a large vendor. For now, the deal stands as one of the more striking data points on how quickly the infrastructure layer for AI agents is being built, priced, and consolidated.
