启动资金：~$40M across two rounds from Sequoia, Tiger Global and others, plus a $5M strategic investment from Cisco

起因

经过

Cisco invested $5M a year before the exit; by mid-2024 Robust had ~$10M annual revenue and 70 employees, with major banks among customers; the EU AI Act formally took effect on 1 Aug 2024; Cisco announced its intent to acquire Robust on 26 Aug 2024, with US reports valuing the deal around $400M; the acquisition was completed on 24 Sep 2024.

结果

Acquired by Cisco — announced 26 Aug 2024, completed 24 Sep 2024; founder Yaron Singer joined Cisco as a senior executive, and the technology became Cisco's security-for-AI line within the Cisco Security Cloud.

可借鉴之处

当初创公司的押注是风险将受监管时，监管者的时间表可成为其退出日历——规则生效时，老牌企业收购品类领导者，因此先打造品类。
