The search startup Glean just announced a new funding round that would double its valuation in just six months, raising $260 million at a $4.6 billion valuation. Plus, shares of Oracle are hitting all-time highs today after posting an earnings beat along with a slew of data center announcements and cloud computing partnerships. Keeping the edge though, could prove difficult for its chaiman Larry Ellison.
