About Alysia Silberg
Alysia Silberg is CEO and Founder of Street Global, an investment and media company based in San Francisco. Her bio says she grew up in South Africa. It describes her as a statistician who co-founded an enterprise voice analytics company, later acquired by a top-5 life-sciences company, and a global employee benefits company that was also acquired. Her site lists mathematics, statistics and financial modeling studies at Cambridge, Harvard, Stanford and UC Berkeley.
She is the author of UNEMPLOYABLE: How I Hired Myself. She founded and hosts the Global FiresideChat radio show on entrepreneurship and investing, which reports listeners in more than 65 countries. She is a UN Women Empower Women Global Champion and a Fellow of the RSA, the Royal Statistical Society and the IoEE.
She also advises Canadian, European, ASEAN, African and emerging-market governments on startup ecosystem development, technology access and trade.
Crunchbase classes her as an individual/angel investor at the seed and early-stage level, but its public counts are small (1 investment, 1 portfolio company, 1 exit). PitchBook lists a larger record under Street Global: 31 investments, 20 portfolio companies and 10 exits. These figures come from third-party databases and may be incomplete.
PitchBook dates a Seed round in Eztia to September 2025 and a Seed round in Aragorn to October 2022. It lists Bear Flag Robotics as a former holding, with an exit dated August 2021.
Her listed AI-related investments include Ideaflow (AI for collaboration), Spect (AI for health), Talus Bio (proteomics and AI), Bear Flag Robotics (robotic tractors and AI), Lofty.ai (real estate, AI and crypto assets) and Ambience. PitchBook dates an Ambience Healthcare investment to December 2023, and also lists Helicone (August 2023) and Middleware (August 2023). Her bio says she specializes in crypto, artificial intelligence and data-driven solutions.
Her stated strategy is to back performance-driven companies that solve big problems in very large markets. She looks for professionalized founders pursuing accelerated, venture-backed growth. An earlier Street Global description cites clear multi-billion-dollar markets and the potential to reach billion-dollar valuations in 5 to 10 years.
Sectors are AI, crypto, health, sustainability and cybersecurity. Her work spans Silicon Valley, Europe and emerging markets, including Africa and India. She says she introduces portfolio companies to customers, strategic alliances, international opportunities, new technologies and acquirers. No check size is published by her or Street Global.
