Sandbox Studios Research
Investment Thesis
Sandbox Studios is a $30M seed-stage venture capital fund based in West Hollywood, Los Angeles, founded in 2021 by Jackie Fast. The fund invests exclusively in consumer brands that are founded by or partnered with A-list celebrities. Their core thesis is that celebrity brands outperform when ownership, distribution, and execution are aligned. Rather than treating celebrities as mere endorsers, Sandbox Studios structures talent as equity owners and treats them as a powerful marketing and distribution asset.
As Jackie Fast puts it: "I don't look at the celebrity as a person or a founder. I look at the celebrity as the marketing arm or the marketing special dust that you can add to a product." The fund believes the future of consumer is "founder-led and culturally powered" — not just celebrity-endorsed.
Sector Focus
Sandbox Studios invests across a range of consumer verticals, united by the common thread of celebrity involvement:
- Food & Beverage — Canned cocktails (XED), protein bars (NuSkool Snacks), ice cream (Dr. Bombay), upcycled candy (Climate Candy), premium canned wine (Maker Wine), beverage technology (Next Century Spirits)
- Beauty & Personal Care — Beauty (Sarelly), personal care (HawthornE)
- Health & Wellness — Sustainable healthcare (Cabinet Health), supplements (The Absorption Company)
- Lifestyle & Home — Cleaning products (Safely), home emergency kits (JUDY), fashion (Destree)
- Media & Entertainment — Media & IP (Invisible Universe)
- Technology/SaaS — Influencer SaaS (Superfiliate), Web3 (Unblocked)
They explicitly focus on brands where celebrity founders bring real distribution, credibility, and cultural relevance — not just awareness.
Stage Focus
Sandbox Studios primarily invests at the seed stage. Their Fund 1 ($30M, 2021 vintage) is a seed-stage vehicle. They partner early with founders building the next generation of consumer and commerce brands.
Check Size
As a $30M seed-stage fund, typical check sizes are estimated in the $250K–$2M range based on fund size and portfolio count (17+ companies visible on their website).
Lead Tendency
Based on available data, Sandbox Studios appears to both lead and follow rounds. The Maker Wine investment (October 2024) and other portfolio investments suggest they can lead seed rounds in their core thesis area. Third-party data from Raizer suggests they typically follow, but given their specialized thesis and hands-on approach, they likely lead in deals where they have strong celebrity-brand conviction.
Recent Activity
Sandbox Studios has been actively deploying from Fund 1:
- October 2024: Invested in Maker Wine, a female-founded premium canned wine brand
- February 2025: Participated in a $1.2M seed round (per ReFED Capital Tracker)
