Nasuni, a Boston-based company that sells cloud file storage and unstructured data management software to large organisations, said on 4 March 2026 that it had acquired Resilio, a Bay Area company that makes high-performance file synchronisation and edge acceleration software.
The companies did not disclose the price or any other financial terms. KPMG Corporate Finance acted as Resilio's exclusive investment banking adviser. Nasuni described the deal as completed and said the two companies had started a phased integration of their teams, technology and operations.
Nasuni said existing Resilio and Nasuni customers and partners would keep receiving the same level of service and support during the transition, and that it would share more details about its plans in the following weeks.
What Resilio built
Resilio began as BitTorrent Sync, a peer-to-peer file synchronisation product that BitTorrent Inc. launched in 2013 and that was first pitched as a consumer rival to Dropbox. In June 2016 BitTorrent split the Sync business into a separate enterprise-focused company named Resilio, led by former BitTorrent chief executive Eric Klinker, who remained CEO at the time of the sale.
Blocks and Files named Ilan Shamir and Konstantin Lissounov, both former BitTorrent executives, as co-founders. Lissounov co-invented the original Sync technology. The company sells Resilio Connect, an agent-based product for larger businesses that runs over an organisation's existing storage and network and adds WAN acceleration, as well as lighter Sync products for small businesses and individuals.
Resilio now calls its product line the Active Everywhere Platform and says it is used for data-heavy work in architecture and engineering, media and entertainment, and financial services. In a 2024 profile, Blocks and Files reported that one customer ran more than 100,000 Resilio endpoints in its network. Resilio has not published its funding history or headcount, and the deal announcement did not include either.
“We're excited to welcome the Resilio team to Nasuni. Our customers already rely on Nasuni to manage, protect and activate their enterprise file data on a global scale.”
Why Nasuni is buying
Nasuni sells a software-defined network-attached storage and data management platform built on its patented UniFS global file system. The company says it has enterprise customers in more than 70 countries and a 98% customer satisfaction rating.
Nasuni plans to combine its cloud-based file services with Resilio's synchronisation and caching technology so that employees in offices, remote sites and hybrid setups can open shared files quickly. The company said this would reduce the need for VPN connections, separate sync tools and expensive hardware, while IT teams keep central control over security and governance.
Nasuni also said Resilio would help it move into high-speed data transfer and data orchestration, including for remote locations with limited bandwidth. Channel Insider reported that Nasuni presented the deal as a step towards moving data for AI and analytics pipelines.
Nasuni chief product officer Nick Burling said Resilio fitted the company's strategy for the Nasuni File Data Platform.
The leadership
Nasuni chief executive Sam King welcomed the Resilio team and said the deal would extend the Nasuni platform to improve enterprise productivity while simplifying operations and protecting IT environments.
Klinker had run BitTorrent before the 2016 split. When the separation was announced, BitTorrent co-chief executive Robert Delamar said the two businesses would be stronger apart, one focused on consumer media and the other on enterprise customers, and that Klinker was taking the part of the business he knew best.
Klinker said he was proud of what the Resilio team had built and described joining Nasuni as the next step for the company. Nasuni did not say what roles Resilio's leaders would take after the integration.
What happens to customers
Resilio's products remain available while the integration runs. Nasuni has not said whether the Resilio brand will be kept or folded into the Nasuni File Data Platform, and it gave no timetable for combined products beyond promising further updates.
The deal adds edge sync and transfer technology to a company that has built its business on central cloud storage, a combination aimed at teams that need to work on large files across many locations.
