Who are Glean's decision-makers?
Glean's executive bench combines deep technical founders — all with search and infrastructure pedigrees from Google and Facebook — with proven enterprise-software operators recruited to scale the business through its growth phase. The founding team retains significant operational authority, with CEO Arvind Jain and CTO T.R. Vishwanath directing product strategy, while President Tamar Yehoshua and COO Amar Maletira run the scale-up functions of product, engineering, and go-to-market.

Who leads Glean?
Arvind Jain is co-founder and CEO. Before Glean, he was a Distinguished Engineer at Google for over a decade, leading teams across Search, Maps, and YouTube. He then co-founded Rubrik — the data security company that went public on the NYSE in April 2024 at a multi-billion dollar valuation — where he ran all of R&D. This track record of taking a technical startup through hyper-growth and a public offering makes him one of the more experienced CEOs in the enterprise AI space.
T.R. Vishwanath is co-founder and CTO, drawing on prior work at Facebook building News Feed and Ads infrastructure at massive scale, and 8 years at Microsoft before that. He owns Glean's core search architecture, the permissions-aware knowledge graph, and AI research functions including the Waldo reinforcement learning model. Tamar Yehoshua joined as President, Product & Technology in March 2024; at Google she led the Search Experience team, and at Slack she was Chief Product Officer during the company's 10x revenue growth, public listing, and $27.7B acquisition by Salesforce — bringing directly applicable scale-through-transition experience.
Who actually makes buying decisions at Glean?
Glean's enterprise sales cycles typically involve three buyer personas working in concert. The economic buyer is the CIO or CITO — who signs off on six-figure or seven-figure annual commitments. CIOs are drawn to Glean's security story (permissions-aware retrieval, no data duplication, Glean Protect Plus governance), its model-neutral architecture that avoids LLM vendor lock-in, and the availability of on-premises deployment (via the Dell Technologies partnership) for regulated industries.
The technical champion is usually a Director or VP of Engineering, IT, or Workplace Technology who evaluates the depth of the 100+ connector integrations, API flexibility, MCP server/host support, and administrative tooling for permissions management. The end-user champion is often a head of People/HR or a functional leader in Sales Ops or Customer Success who has a concrete productivity use case — AI-assisted onboarding, contract Q&A, or customer context retrieval. Deal velocity is typically set by how quickly the CIO and technical champion align on security and integration requirements; end-user adoption rates then drive renewal and seat expansion.
How is Glean organized as it scales toward 2,000+ employees?
Glean operates with a dual-track structure at the executive level: Tamar Yehoshua owns Product and Engineering, and Amar Maletira owns Sales, Customer Success, Finance, and Operations. This clean split between product-technology and go-to-market is typical of enterprise software companies preparing for a public offering. Maletira confirmed active in his COO role in May 2026 when he welcomed public-sector leaders at Glean's California State Innovation Day in Sacramento.
With approximately 1,650 employees across Palo Alto, San Francisco, New York, London, and Bangalore, Glean is at the inflection point where organizational design and process infrastructure matter as much as raw hiring speed. The Glean:GO conference initiative — launched in 2025, with its 2026 edition at Fort Mason, San Francisco on August 26–27 — signals an intent to build a user community and partner ecosystem, a move typical of platforms preparing for a public market debut. Sunil Agrawal as CISO reflects the company's emphasis on enterprise security as a first-class sales motion, not an afterthought.
