Company profile
researched Aug 2026Pure Storage was founded in 2009 in Silicon Valley, incubated inside Sutter Hill Ventures under the code name "Os76, Inc." (Delaware entity formed 2009-11-03 per SEC EDGAR former-names records). Sutter Hill managing director Mike Speiser served as the company's founding CEO, investor and board member starting around October 2009 -- a pattern Sutter Hill later repeated with Snowflake. The technical co-founders were John Colgrove (an engineer previously at Veritas Technologies and Amdahl, and an entrepreneur-in-residence at Sutter Hill, BS Rutgers University), who became Pure Storage's chief architect and later Chief Visionary Officer, and John Hayes, who became co-founder and chief architect/CTO. The company emerged from stealth in 2011. Its first product, FlashArray, launched in 2011, pioneering all-flash arrays for mainstream enterprise storage (versus traditional spinning-disk arrays), pitched on lower power/space footprint and better performance/economics via data reduction.
Funding history (pre-IPO, per Wikipedia's history section, cross-checked against Crunchbase's (partially paywalled) round count of 8 total pre-IPO+secondary rounds): an early ~$5M round, a Series B of ~$20M, a Series C of $30M in August 2011 (coinciding with the company coming out of stealth), a $40M round in August 2012 supporting European expansion, an undisclosed investment from In-Q-Tel (the CIA's strategic venture arm) in May 2013, a $150M round in August 2013, and a $225M Series F in 2014 that valued the company at roughly $3 billion. Total pre-IPO venture capital raised is reported at over $470 million. Confirmed/likely investors across these rounds include Sutter Hill Ventures (earliest/lead), Greylock Partners (first partnered at Series B per Greylock's own portfolio page, with venture partner Aneel Bhusri as the named Greylock investor), Redpoint Ventures, Index Ventures (whose partner Mike Volpi later joined Pure Storage's board in July 2012), Samsung Ventures, T. Rowe Price, Tiger Global, DAG Ventures, and In-Q-Tel; a definitive round-by-round investor breakdown could not be fully confirmed because Crunchbase's public page kept detailed investor/date data behind a login paywall.
Pure Storage went public on the New York Stock Exchange on October 7, 2015 under ticker PSTG, selling roughly 25 million shares for about $425 million (implying roughly $17/share), pricing at a valuation below its last private "unicorn" mark -- a widely-covered "down-ish" tech IPO of that era; multiple outlets noted shares ended below the IPO price on their market debut. Founding CEO Scott Dietzen (who had succeeded Speiser as CEO before the IPO) led the company through the offering. In August 2017, Charles Giancarlo -- a former Cisco CTO/EVP, former Avaya CEO, and Silver Lake operating partner -- was named CEO, replacing Dietzen; Giancarlo remains Chairman and CEO as of 2026. Founder John Colgrove remains a board member and, per current filings, holds the title Founder, Chief Visionary Officer and Director; co-founder John Hayes departed operational duties over time and now appears as an advisor, having gone on to found autonomous-vehicle startup Ghost Autonomy.
Business model
B2B enterprise hardware and subscription software/services company; sells all-flash storage arrays (FlashArray, FlashBlade) and increasingly monetizes via the Evergreen subscription family (including Evergreen//One Storage-as-a-Service) and cloud-native/Kubernetes data services (Portworx), moving from a capex hardware model toward recurring subscription/ARR revenue.
Product revenue from sale/lease of flash storage hardware plus growing subscription services revenue (Evergreen//One STaaS, Portworx, software/support contracts); reports both product and subscription services revenue, with subscription ARR exceeding $1 billion by fiscal 2023.

Profile (continued)
Product line expanded with FlashBlade (2016, unstructured/file and object storage aimed at AI/analytics/HPC workloads, later extended as FlashBlade//EXA in 2025), the Evergreen subscription family (2015) that lets customers non-disruptively upgrade controllers/media under a single subscription, and Evergreen//One (2018), a true Storage-as-a-Service/consumption offering. Pure Storage made several acquisitions to broaden beyond arrays: StorReduce (August 2018, ~$25M, cloud data deduplication), Compuverde (April 2019, undisclosed, scale-out file software), and -- most significantly -- Portworx (announced August/closed September 2020, ~$370M), a Kubernetes-native container data management platform that became the core of Pure's cloud-native/DevOps strategy. In February 2026 the company announced a definitive agreement to acquire 1touch.io, a data intelligence/discovery and orchestration company, alongside a broader corporate rebrand.
Financially, Pure Storage grew from about $6M revenue in fiscal 2013 to $43M (FY2014), $174M (FY2015), and crossed $1 billion in annual revenue in fiscal 2018 (its first GAAP-profitable year). By fiscal 2023 subscription/ARR had surpassed $1.1 billion, and by fiscal Q4 2026 quarterly revenue exceeded $1 billion. As of August 19-20, 2026, trailing-twelve-month revenue was reported at roughly $3.94B (up ~21% y/y), with the stock trading around $112/share and a market capitalization of roughly $37.2 billion (per stockanalysis.com), reflecting strong investor enthusiasm tied to AI-era data infrastructure demand (the company has partnered with NVIDIA, Cisco and SK hynix on AI-optimized storage). The company also made a notable strategic investment, participating in a CoreWeave secondary share sale around November 2024 (per Wikipedia), signaling exposure to the AI-cloud infrastructure boom.
IMPORTANT / UNUSUAL FINDING -- CORPORATE REBRAND: Multiple independent-seeming sources (Wikipedia's Pure Storage/Everpure article, SEC EDGAR's submissions JSON for CIK 0001474432, a PR Newswire press release dated February 23, 2026 titled "Pure Storage Becomes Everpure; Announces Intent to Acquire 1touch," and stockanalysis.com's live quote page) consistently indicate that Pure Storage, Inc. formally renamed itself Everpure, Inc. in early 2026, with the new brand debuting in market communications on/around March 5, 2026. There is some inconsistency across sources about the ticker: the February 23, 2026 press release stated the ticker would remain NYSE: PSTG under the new name, while SEC EDGAR's current filer record and stockanalysis.com's live quote (as of August 19-20, 2026) show the ticker as simply "P" on NYSE. This suggests a ticker change occurred at some point after the initial rebrand announcement, or reflects source lag. Because this rebrand falls after this researcher's normal knowledge cutoff and could not be triple-verified via a fully independent, non-AI-summarized primary source (e.g., a manually rendered SEC filing or a second wire service), it is flagged here as a plausible-but-not-ironclad fact. For purposes of this record (which tracks the company historically known as, and originally invested in as, "Pure Storage"), the entry retains the name "Pure Storage" and historic ticker "PSTG,” with the rebrand fully documented in this narrative for the database maintainer's awareness. If confirmed false on further review, all "Everpure"-related content above should be disregarded and the company treated as continuously named Pure Storage, Inc. / NYSE: PSTG through 2026.
Competitively, Pure Storage/Everpure operates in the enterprise/AI data storage market against NetApp, Dell Technologies (PowerMax, PowerStore, Unity XT), Hewlett Packard Enterprise (HPE Alletra, 3PAR, Nimble Storage), IBM (Storage FlashSystem), Hitachi Vantara, Huawei, and newer all-flash/AI-storage entrants such as VAST Data and Infinidat, as well as open-source alternatives like TrueNAS. Pure has consistently been named a Leader in Gartner's Magic Quadrant for primary storage for roughly a decade-plus. A significant historical event was patent/trade-secret litigation with EMC (2013-2016) over alleged reverse engineering and trade secret theft, which the companies settled for $30 million in 2016. More recently, in 2024, Pure Storage was named among companies affected by a third-party Snowflake-account data breach; the company stated no customer PII was compromised, though some internal system information was accessed.
