Bird Is Said to Raise New Funding at $2.5 Billion Valuation

SAN FRANCISCO — Bird, a start-up that rents out electric scooters, is being valued at $2.5 billion in a new funding round led by the venture capital firm Sequoia Capital, according to three people with knowledge of the deal.

The funding puts Bird’s valuation slightly above the $2.3 billion that it was pegged at last year. At the time, the $2.3 billion figure represented double the start-up’s previous valuation, as venture capital investors fought to pour money into scooter start-ups.
