Wave Capital

Wave Capital Research Investment Thesis Wave Capital is a seed-stage venture capital firm founded in 2017 by three experienced operators: David Rosenthal (formerly of Madrona Venture Group), Sara Adler (former head of corporate development at Airbnb, with prior roles at Facebook and Dropbox), and Riley Newman (one of Airbnb's first 10 employees, former head of data science). While initially dubbed the "Airbnb Mafia" fund due to its founders' backgrounds, Wave has evolved its thesis to focus more broadly on exceptional founders from top-tier technology companies—what the partners term the "unicorn mafia." The firm's core belief is that great companies are built with exceptional teams who have a real mission and deep experience. Wave invests in founders who have operated at scale in world-class organizations like Airbnb, Dropbox, Uber, Facebook, and DoorDash. The fund operates with a highly concentrated, selective approach: it aims to make no more than four investments per year, leads most rounds, and takes a hands-on operational role with each portfolio company. Operating Philosophy Wave operates as a lean, partnership-driven firm with no dedicated staff beyond the three founding partners. This structure ensures that the partners bring their full operating backgrounds and expertise directly to portfolio companies. The founders have stated: "Our success is determined by the success of the companies we back." This alignment means partners serve as de facto operational members of founding teams, providing guidance not just on fundraising and strategy, but on organizational building and go-to-market execution. The firm's willingness to engage deeply with founders is evidenced by their approach: they sometimes work with entrepreneurs before a specific venture idea is crystallized, helping them brainstorm and evaluate opportunities. For example, they worked with Henrik Berggren (formerly of Dropbox) to explore ideas before settling on Steady Health, a modern clinic focused on diabetes management. Investment Approach & Stage Focus Wave Capital is a seed-stage venture fund. Based on available data: Primary stage: Seed rounds and pre-seed investments Secondary stage: Series A for strong portfolio follow-ons Check size: Historically in the range of $1M-$3M for seed rounds (based on portfolio data) Lead/Follow: Wave leads or co-leads the vast majority of its investments Portfolio strategy: Highly concentrated with ~4 investments per year, total of 26+ investments across the fund's lifetime Recent Activity & Portfolio Wave Capital closed its first $55 million fund (Wave I) in July 2018. As of early 2025, the fund has made 26 investments with notable recent activity: Recent Investments (2024-2025): mpathic (Series A, March 2025): $8.07M investment, co-led with Foundry and Next Frontier Capital Ohana (Seed, June 2024): $3M investment alongside angel investors and other VCs Synternet (Seed, March 2024) Portfolio Exits: Boox (Acquired by FabFitFun, July 2025) One additional acquisition in January 2023 Notable Portfolio Companies: Alma: Marketplace for charitable donations (founded by Dan Hill and Michelle Rittenhouse, both former Airbnb employees) Steady Health: Modern diabetes management clinic (founded by Henrik Berggren, formerly of Dropbox) Twity: Web3 marketing platform (raised $1.5M Series A + $5M PE round in January 2023) Locale, EPNS, Huddle, The Luupe: Additional early investments The portfolio reflects the evolution from Airbnb-focused to broader "unicorn mafia" thesis: many founders come from Airbnb, but an increasing number originate from Dropbox, Uber, DoorDash, and other scaling tech companies. Sector and Market Focus Wave Capital focuses on marketplace models and consumer-centric businesses, reflecting the founders' deep expertise in these domains from their Airbnb experience. The portfolio shows some concentration in: Marketplaces: Alma (charitable giving), Locale (community), and other marketplace models Consumer Services: Healthcare (Steady Health), real estate services (Ohana), and other direct-to-consumer businesses Web3/Emerging Tech: Demonstrated by investments in projects like Twity and EPNS (Ethereum Push Notification Service) However, the fund has signaled openness to high-quality founders from any sector where those founders bring operational expertise from tier-one companies. Geographic & Demographic Preferences Geographic Focus: Primarily United States, with clear focus on San Francisco Bay Area where the fund is headquartered. Open to national opportunities where strong founder networks exist. Founder Preferences: Experienced operators from top-tier technology companies (Airbnb, Dropbox, Facebook, Uber, DoorDash, etc.). The fund has shown particular enthusiasm for: Co-founders with complementary skills (e.g., product + data science + operations) Teams that knew the Wave partners from previous work Founders with proven success in scaling operations at large organizations Mission-driven founders with clear convictions about what they want to build Decision Making & Involvement Decision Process: Partnership model where all three partners participate in major investment decisions. Small fund size (3 partners, no staff) means tight-knit decision making. Timeline: Not explicitly stated, but the selective approach (4 investments/year) suggests deliberate, thoughtful evaluation process. Board/Involvement: Partners take active roles—often board seats or deep advisor relationships. Portfolio founders have described them as "members of the early team" rather than passive investors. Fund Status & Deploy Rate Based on timing: Wave I: Closed July 2018 with $55M Current status: Actively deploying as of February 2026 Activity: Recent investments in 2024-2025 suggest fund is still in growth phase, likely raising for Fund II Deployment pace: Conservative (4 investments/year) means typical 10-year deployment window Competitive Positioning Wave Capital occupies a unique position in the seed venture market: Differentiation: Deep operating expertise from world-class tech companies Network: Strong alumni networks from Airbnb, Dropbox, Facebook, and other major tech firms Value-add: Partners bring hands-on operational guidance, not just capital Focus: Concentrated portfolio allows deep engagement with each founder Segment: Fits within the broader "mafia investing" phenomenon where alumni from successful companies band together to back similar talent Market & Macro Context Wave operates in the competitive seed-stage venture market where capital has become increasingly abundant. The fund's thesis about doubling down on exceptional operators from proven companies is a response to the recognition that founder quality and execution capability are primary drivers of startup success. The firm's reluctance to be constrained by old networks (Airbnb-only) reflects broader industry recognition that talent and entrepreneurial drive emerge from many sources.
