Large blocks of space are in high demand among Bay Area tech companies expanding into and within San Francisco, but startups and small tech companies from outside of the Bay Area are carving a niche within the city as well. Some are taking advantage of leasing smaller office blocks or moving into co-working space as an entry into the city's office industry.

“San Francisco continues to attract startups that are in hyper-growth mode,” Kilroy Realty Senior Vice President, Asset Management Rick Buziak said in a press release.

Tel Aviv-based AppsFlyer opened an 11K SF U.S. headquarters in mid-February at Kilroy Realty’s 100 First St., where Okta signed a 207K SF lease in December. The South of Market office offers capacity for further growth. The mobile attribution and marketing analytics company recently secured $56M in Series C financing. The office on the 25th floor offers an open-office plan.

Adikteev entered San Francisco to be closer to its San Francisco-based clients, tech partners and publishers, according to Adikteev Chief Revenue Officer for Apps and Managing Director, USA, Alexei Chemenda.

“San Francisco is the center of innovation where all tech companies are concentrated,” Chemenda said in an email. “Most of our mature clients are often [San Francisco]-based, and it’s important for us to be close to them to understand their needs and adapt our product.”

The France-based mobile marketing platform company secured $12M in a Series B funding round and plans to grow internationally. It also recently opened an office in New York City. Adikteev combines creative technology, data and artificial intelligence for advertisers and app developers.

By the end of 2018, there will be approximately 10 to 15 Adikteev employees at WeWork's Montgomery Station office at 44 Montgomery St.
