Cleversafe

Cleversafe is a Chicago-born data‑storage company that built a patented, distributed object‑storage system for hyperscale, exabyte‑class data stores and was acquired by IBM in 2015 for roughly $1.3–1.4 billion[4][9].

High‑Level Overview

• Cleversafe built a distributed object storage platform designed to store very large volumes of unstructured data (what the founder described as a mission “to store the world’s data”)[1][3].
  - The product served large enterprises and public sector customers (examples cited in reporting include Shutterfly and U.S. Department of Defense customers) seeking scalable, durable, cost‑effective archival and active archive storage at hyperscale[4][6].
  - The technology solved the problem of scaling storage beyond traditional filesystems by using a novel combination of data dispersal, encryption, and commodity hardware to provide durability, security, and lower cost per byte for exabyte‑scale stores[6][4].
  - Growth momentum: Cleversafe grew from a long R&D and patent phase into a leading object‑storage player, amassed a large patent portfolio, and achieved a high‑value exit to IBM in 2015 that materially impacted the Chicago startup ecosystem[6][7][9].

Origin Story

• Founding year and founder: Cleversafe was founded in 2004 by Chris Gladwin, who led the company through its product development and commercialization[2][6].
  - How the idea emerged: Gladwin’s background in prior startups and a deep interest in encryption and distributed systems led him to apply ideas from encryption and linear algebra to create a new format and architecture for storing and protecting data on commodity hardware; he framed the company’s long‑term goal as storing the world’s data[1][8].
  - Early traction / pivotal moments: The company spent several years on technology development and building IP before landing its first enterprise customers (a normal pattern in enterprise storage), accumulated a large patent portfolio (over 1,000 patent applications/grants cited in reporting), and ultimately achieved a sale to IBM in 2015 that reportedly created dozens of millionaire employees and injected capital and experience back into the Chicago ecosystem[6][7][9].

Core Differentiators

• Architecture and data protection: Used dispersed object storage (data slicing/distribution and strong cryptographic protection) to provide durability and confidentiality without heavy reliance on replication, enabling lower storage cost at scale[6][4].
  - Patent and IP position: Very large patent portfolio (reporting cites hundreds to over a thousand patent filings/grants tied to Cleversafe), giving the company defensible technology and market credibility[6][7].
  - Hyperscale focus and commodity economics: Designed from the ground up to run on commodity hardware and scale to exabytes, targeting customers with massive, growing datasets[4][6].
  - Ecosystem and regional impact: Anchored in Chicago and closely connected to local universities and tech organizations (e.g., Illinois Tech relationships), which helped recruit talent and seed later regional investments by former employees and investors after the exit[6][9].

Role in the Broader Tech Landscape

• Trend alignment: Cleversafe rode the wave of exploding unstructured data volumes and the industry shift toward object storage as the dominant model for large‑scale, cloud‑native and archival storage needs[4][6].
  - Timing: Founded in the mid‑2000s, Cleversafe’s architecture and timing coincided with the rise of big data, cloud workloads, and customers needing durable, cost‑efficient storage at hyperscale—conditions that made its approach commercially attractive[1][6].
  - Market forces: Increasing data creation (media, scientific, telemetry, backup/archival) and a push to reduce per‑byte costs favored designs that replace expensive monolithic storage with distributed, software‑defined systems on commodity servers[4][6].
  - Influence: The company’s technology and patents influenced the object‑storage category and contributed to the mainstreaming of distributed object architectures; its high‑value exit also galvanized Chicago’s venture and startup scene by returning capital and experienced founders to the region[7][9].

Quick Take & Future Outlook

• What’s next (historical consequence): After Cleversafe’s acquisition, IBM integrated the technology into its storage portfolio; the founder, Chris Gladwin, leveraged the experience and capital to fund and found new ventures and philanthropic initiatives that continue to shape Chicago’s tech scene[4][8][9].
  - Trends that will shape the story: Continued growth in unstructured data, demand for secure and cost‑efficient long‑term storage, and cloud/hybrid storage architectures sustain the relevance of the object‑storage model Cleversafe helped commercialize[4][6].
  - How influence may evolve: Cleversafe’s main legacy is technological (object storage approaches and IP) and regional (a demonstrated big exit that seeded talent and investors). That combination—tech IP plus ecosystem capital—tends to produce ongoing startup activity and innovation in data infrastructure from former employees and local investors[9][7].

Quick takeaway: Cleversafe is a pioneering object‑storage company founded by Chris Gladwin in 2004 that built a patent‑rich, distributed storage architecture for exabyte‑scale data, culminating in a transformative IBM acquisition in 2015 and lasting influence on both enterprise storage design and the Chicago startup ecosystem[2][6][9].
