Andreessen Horowitz Expands Fifth Growth Fund to $8.5B

Andreessen Horowitz said on August 31, 2026 that its Growth practice has closed additional capital, bringing the firm’s fifth Growth fund to a total of $8.5 billion. The firm disclosed the expansion in a post co-authored by David George, the general partner who leads its Growth investing team, and Raghu Raghuram, a managing partner and general partner on the Growth and Infrastructure investing teams.

The additional close enlarges a vehicle the firm first announced earlier this year. Andreessen Horowitz said on January 9, 2026 that it had raised more than $15 billion across new funds, including $6.75 billion for the Growth fund, $1.176 billion for American Dynamism, $1.7 billion for Apps, $700 million for Bio + Health, $1.7 billion for Infrastructure, and $3 billion for other venture strategies. In that announcement, cofounder Ben Horowitz said the haul represented more than 18% of all venture capital dollars allocated in the United States in 2025.

An Expanded Fund for a Larger Market

George and Raghuram wrote that the additional capital “became the obvious thing to do for both founders and our Limited Partners,” pointing to what they described as an unusual investing environment with at least six mega-trends emerging at once.

The trends they identified are enterprises putting AI tools to work across their organizations, with the authors stating they believe there is no upper bound on the demand to turn compute into business outcomes; consumer AI, which the authors described as barely a thing yet beyond ChatGPT’s form factor beginning to replace the search engine, though they expect it will be transformational when the time is right; American Dynamism, where they see national security, industrial policy, and technological progress converging to rebuild physical systems spanning defense, manufacturing, energy, infrastructure, and space; robotics and autonomy, which they described as poised to be the biggest distributed infrastructure deployment in our lifetime; healthcare, which they noted represents 18% of GDP; and the rebuilding of the entire compute stack for the AI era.

The authors framed the fund’s purpose around founders rather than technology alone, writing that technology has become powerful for company-builders while remaining unevenly diffused across the economy, and that their job as investors is to identify founders and help them however they need.

Scaling Through Inflection Points

The post described the growth stage as a series of inflection points where a founder’s early instincts are no longer sufficient and companies must become multi-product, multi-channel, and multi-geography, often all at once. The authors cited Databricks evolving “Lakehouse” into what they called a dominant platform, and SpaceX evolving from a launch provider into a global communications, data infrastructure, and AI company, as examples of the transitions growth-stage companies face.

Andreessen Horowitz said that in its more than seven years running a16z Growth, the practice has helped over 100 companies through these transitions. The firm’s Growth page states that the practice invests in the market leaders in technology and manages over $24 billion across five vintages; its listed portfolio includes Anduril, Coinbase, Cursor, Databricks, Figma, OpenAI, SpaceX, Stripe, Waymo, and Wiz.

An Expanded Growth Platform

Alongside the capital, the firm detailed an expanded set of Growth Platform offerings aimed at sales, marketing, and pricing. The platform gives portfolio companies access to the firm’s expertise, network, and infrastructure for growth-stage companies, including a go-to-market team that connects companies with new customers, a talent network for executive and technical hiring, global efforts covering international capital, partnerships, and customers, and a New Media team for brand building.

The new offerings cover six areas: sales and marketing leadership, including team structure for the next stage of growth; AI-native go-to-market work spanning agentic operations, AI-native revenue operations, demand generation, and consumption-based pricing; go-to-market strategy and positioning, including ideal customer profiles, category narrative, and core messaging; scaling sales and marketing motions from founder-led sales to revenue engines; pricing and packaging as companies move from single product to platform, including what the firm called AI margin governance; and revenue operations, including compensation plan design and usage-based pricing transitions.

The firm said the operators leading these expanded efforts previously spent time in-house at or closely advised companies including Lovable, Atlassian, Samsara, 1Password, Miro, PagerDuty, Segment, and Workday during their hypergrowth and pre-IPO years.
