Act One Ventures Research
Investment Thesis
Act One Ventures invests in extraordinary founders transforming how modern businesses operate and scale in the AI economy. Founded in 2016 and headquartered in Los Angeles, Act One partners with early-stage entrepreneurs building the next generation of AI-native systems that fundamentally reshape enterprise operations—not just making them faster, but fundamentally different.
The firm's core thesis centers on companies rearchitecting the systems behind modern enterprise: infrastructure, automation, and decision-making. They believe that AI represents a new computing paradigm (like the microprocessor or the internet) that rewrites what's possible, and they seek to back the outlier founders who are rebuilding core business systems from the ground up.
Investment Focus Areas
Act One targets three primary investment verticals within AI-native enterprise software:
Compliance & Risk Infrastructure: AI platforms that keep enterprises honest, secure, and audit-ready. They back companies building oversight systems into the age of automation—governing how AI is deployed, monitored, and held accountable at scale. Recent investments include Optimal AI (code review automation) and Metatate (data policy management).
Commerce & Logistics: Smarter systems for how products are discovered, priced, delivered, and managed. Act One invests in AI-powered operations platforms that turn logistics into prediction engines, powering faster fulfillment, cleaner data, and real-time decision-making from warehouse to checkout. Portfolio companies include Nearfleet (hub-less delivery), Chord (commerce data platform), and Latii (construction materials supply chain).
Fintech & Payments: New financial infrastructure powered by AI that replaces manual review and slow decisions with systems that think, learn, and move money instantly. Investments include GAIL (Voice AI for financial services), Finix (payment infrastructure), and Track Royalty (AI-powered royalty accounting for music industry).
They explicitly avoid non-technical founding teams, consumer apps, and non-AI-native businesses.
Investment Stage & Check Size
Act One leads at Pre-Seed and Seed stages exclusively. They typically invest $1M-$3M per round, making approximately 7 new investments per year. This "fewer bets, deeper relationships" model allows them to remain highly engaged and provide significant operational support to their portfolio companies.
Portfolio & Track Record
With 60+ portfolio companies and 9 years of operating history, Act One has demonstrated strong execution and founder satisfaction. Notable exits include:
- AuditBoard (acquired by Hg for $3.15B in 2024)—the largest VC-backed M&A exit of 2024. Act One led the Seed round in 2016.
- Repeat (acquired by WeCommerce)
- Silversheet (acquired by Amn Healthcare)
- Qless (acquired by Palisades Growth)
- Thrasio acquisition of Storepath
Recent portfolio additions (2024-2025) include Optimal AI (code review agents), GAIL (Voice AI for financial services), Chord Commerce (AI-powered commerce data platform), and Latii (construction supply chain).
Team & Operational Support
Act One is led by two General Partners with strong founder and operator pedigrees:
- Alejandro Guerrero, General Partner: Previously CEO/Founder of UniqApp, Co-Founder of Live Entertainment Network, Associate at UCLA VC Fund. Deep experience in early-stage company building and scaling.
- Michael Silton, General Partner: Previously Executive Director of UCLA VC Fund, CEO/Founder of Rainmaker Systems (public company), CEO/Co-Founder of UniDirect Systems (sold to Avent). Strong track record building and scaling enterprise software.
Additional core team includes Gabriela Camilli (Sr. Associate, former attorney) and Israel Muñoz (Principal). Act One has assembled a world-class advisory board across critical functions:
- David Chaiken (Technology): Chief Architect at Pinterest, Yahoo, SAP
- Meredith Finn (Finance): CFO at Front, MANTL; Partner at March Capital Partners
- Lara Brooks (Go-to-Market): CRO at DailyPay, VP Sales at Paycom
- Monica Pool Knox (HR & Strategy): CEO of Good Trouble Ventures, 2x public company CHRO, former Microsoft HR executive
- Jan-Christopher Nugent (Sales & Marketing): Co-Founder/CEO of Nogin, VP Sales/Marketing at Digital River
This advisor network provides founders with immediate access to world-class expertise in scaling operations, go-to-market strategy, team building, and technology architecture.
Founder-Centric Approach
Act One's investment philosophy emphasizes:
-
Bringing Founding Experience: The partners approach company building as a craft, offering clear actionable advice, strategic customer introductions, and intentional spacing to let founders execute.
-
Leading with Trust: Beyond capital, Act One's experienced advisors actively support founders in navigating key early decisions. They position themselves as founders' "first call at any hour."
-
Building Around Founder Insight: Act One seeks founders who've lived their problem—people with years of industry experience who understand where legacy systems fail. They partner with technical founders who already possess deep domain expertise.
-
Delivering an Engaged Community: Portfolio founders benefit from access to experienced entrepreneurs and operators (advisors and LPs) eager to open doors, provide feedback, and connect to customers.
Diversity & Inclusion Leadership
Act One is a leader in VC diversity and inclusion. The firm originated and continues to champion the Diversity Rider—a contractual mechanism to include underrepresented investors on cap tables. The Diversity Rider is now used by leading firms including Greycroft, Fifth Wall, Harlem Capital, Plexo, and Precursor Ventures. Act One includes the rider in every term sheet and has built a diverse team and LP base reflecting their commitment to changing the venture landscape.
Geographic & Market Focus
Headquartered in Los Angeles, Act One invests primarily in California (especially LA and Bay Area) and has developed strong networks in New York and emerging tech hubs. They selectively invest outside the US in founders with unique advantages (e.g., Latin America-based founders serving underserved markets).
Recent Activity & Fund Status
Act One raised $73 million for Fund III (closed January 2024), bringing their total assets under management to $148 million across three funds plus multiple SPVs. The firm is currently in active deployment mode, making new investments regularly throughout 2024 and 2025.
Recent investments (2024-2025) include:
- Optimal AI (code review automation, November 2024)
- GAIL (Voice AI for financial services, 2025 seed lead)
- Chord Commerce (AI-powered commerce data platform, 2025)
- Latii (construction supply chain, November 2025)
The fund demonstrates strong recent activity with consistent deployment across their investment thesis areas.
Decision Process & Timeline
Based on portfolio activity and investment volume, Act One follows a partnership-based decision process where both General Partners evaluate opportunities together. Their stated commitment to founder relationships and relatively low investment volume (7 per year) suggests they take time to deeply evaluate opportunities, typically making seed round decisions within 4-8 weeks for promising teams.
Founder Reception
Portfolio founders consistently praise Act One for deep operational experience during scaling, valuable introductions and network access, respect for founder autonomy, and a diverse and inclusive team that genuinely supports underrepresented founders. Daniel Kim (AuditBoard co-founder) noted: "The Act One team brought a level of operational experience that was truly valuable through scaling and financing. They help navigate challenges and bring an incredible network."
