Sept 10 (Reuters) - Enterprise AI search firm Glean

raised over $260 million in a new funding round, doubling its

valuation to $4.6 billion, as investor interest in startups that

deploy artificial intelligence-powered services continues to

grow.

The Series E funding round, led by Altimeter and DST Global,

has boosted Glean's valuation from its previous $2.2 billion in

February.

The company uses conversational AI assistants and large

language models like OpenAI's GPT, which powers ChatGPT, to

generate personalized answers to queries based on a company's

internal data.

Founded in 2019 by former Google employees, Glean counts

Reddit ( RDDT ), Pinterest ( PINS ), Databricks, and others

among its customers.

The company also announced new features that allow users to

create "multi-step" prompts using natural language to remove the

necessity for coding skills or prompt engineering.

Co-founder and CEO Arvind Jain, who also co-founded data

management startup Rubrik, said in February the company plans to

increase hiring.
