Inflection Ventures Research

Investment Thesis

Inflection Ventures is a New York-based venture capital firm built around a single organizing idea: back the companies building the AI infrastructure that will power everything else, alongside the national-security and defense-technology stack that depends on it. The firm's public positioning leans heavily on category creators in AI compute, energy for data centers, defense manufacturing, and cybersecurity. Rather than sourcing brand-new seed deals, Inflection positions itself as an access vehicle into differentiated, high-growth private companies, drawing on more than two decades of relationships across technology and financial services to get allocation into rounds and secondaries that are otherwise hard to reach.

Stage Focus

Inflection explicitly targets late-stage private companies rather than early-stage venture. Its own messaging emphasizes "vigorous revenue generation and sustained growth" as a filter, and the portfolio (Palantir, Databricks, SpaceX, Anduril, CoreWeave, xAI) is dominated by pre-IPO and growth-stage category leaders rather than seed or Series A startups. The firm frames its edge as generating "venture returns in years, not decades" by buying into already-de-risked, fast-compounding businesses, which is consistent with a secondary-market / SPV-style access strategy rather than primary round leading.

Check Size

Check size is not disclosed publicly. Given the profile of portfolio names (some of the largest private technology and defense companies in the market), allocations are likely structured through SPVs or fund-of-one vehicles sized to whatever access is available in a given round rather than a fixed check-size band.

Lead Tendency

Nothing in the public record suggests Inflection leads primary rounds. The portfolio composition and site language ("identify and steward promising private companies," reliance on relationships and access) point to a follow/access investor rather than a lead investor.

Recent Activity

Inflection's own news page functions as a running commentary on its portfolio's momentum rather than a fundraising announcement feed, which itself signals an access-and-hold posture. Recent items (all early 2026) tracked substantial developments across the portfolio: Exowatt launching a dedicated data-center energy division (ExoRise) and a new 24/7 renewable power business line; Anduril reportedly raising up to $8B and separately committing $1B to expand U.S. defense manufacturing; Radiant clearing a DOE safety milestone for its Kaleidos microreactor; Abnormal AI (formerly Abnormal Security) being named to Fortune's 2026 Cyber 60 and closing a $250M Series D at a $5.1B valuation; Nvidia investing $2B into CoreWeave; and SpaceX advancing both an orbital solar network filing and anticipation of a 2026 IPO. This is a firm actively tracking and publicizing the trajectory of large, already-successful holdings.

Portfolio Highlights

Disclosed portfolio companies span four themes: AI infrastructure and data platforms (Palantir, Databricks, CoreWeave, xAI, Vercel, Groq), defense and national security (Anduril, Shield AI, Epirus, CHAOS Industries, SpaceX), energy for compute (Radiant Nuclear, Exowatt), and cybersecurity (Proofpoint, Abnormal Security). Several of these — Palantir, Databricks, SpaceX, Anduril, CoreWeave — are among the most closely watched private/newly-public technology companies in the market, suggesting Inflection's differentiation is access rather than sourcing.

Team

  • Kabe Roshan — Founder and General Partner. Early personal investments in Facebook and Palantir sparked his move into private-market investing; 15+ years and 125+ advanced-technology company investments.
  • Shiven Ramji — Venture Partner. President of Customer Identity Cloud at Okta; two decades in security and developer tools; angel investor in 50+ private companies; board member at Aiven.
  • Karl Feng — Venture Partner. Head of Product at Forge; 20+ years across private markets and fintech, including Carta, Bank of America, Goldman Sachs, and NYSE.
  • Kevin Arsenault — Operating Partner. 20+ years in cybersecurity; early CrowdStrike sales team member and VP at Proofpoint; now CRO at Push Security.
  • Dov Yoran — Strategic Advisor. Co-founder and former CEO of ThreatGRID (acquired by Cisco, 2014); led Cisco's Security Business Group strategy; co-founded Command Zero in 2024.
  • Christiane De Carvalho — Investor Relations. Background spanning marketing, technology, and data-driven martech/adtech innovation.

Decision Process

The firm operates as a partnership of a founder/GP plus multiple venture and operating partners drawn from security, fintech, and infrastructure backgrounds, rather than a solo-GP structure. Domain experts (e.g., Ramji in identity/security, Arsenault in cybersecurity operations) appear to inform sector-specific diligence.

Founder Preferences

Public materials emphasize "founder-driven, technology product companies that aim to change their industries," with a bias toward technical, category-defining teams in AI infrastructure, defense, and energy rather than generalist consumer or SaaS founders.

Geographic Focus

Headquartered in New York, with a Los Angeles presence noted on the site. No explicit international mandate is disclosed; portfolio companies are overwhelmingly U.S.-based.
