AMP PBC Research
Investment Thesis
AMP PBC is a public benefit corporation founded in 2026 by Anjney Midha, a former general partner at Andreessen Horowitz, alongside an engineering co-founding team that previously built large-scale scheduling systems (including Google's Borg/GQM scheduler). AMP's stated mission is to "maximize the world's frontier output" by scaling compute access to unlock frontier AI progress. The firm's core belief is that focused, talent-dense independent teams produce breakthrough AI research faster than large incumbent labs, but are structurally constrained by inefficient and expensive access to compute (AMP cites 30-40% of frontier compute capacity going unused industry-wide). AMP positions itself explicitly as "not a cloud provider, not a traditional VC" but as an independent system operator of a pooled "AI grid."
Business Model
AMP operates a dual structure. An infrastructure arm ("the Grid") pools GPU/compute capacity across data centers and passes it through to portfolio and partner labs near cost, functioning like a utility rather than a markup cloud reseller. A separate venture arm, AMP Foundry, incubates and invests capital directly into frontier AI labs, at times leading or co-leading large rounds. Profits from carry and fees are reinvested into acquiring additional compute capacity, reinforcing the compute-for-equity flywheel. The PBC (public benefit corporation) charter also allows AMP's leadership to commit up to $500M from profits through 2030 toward a separate "Public Wealth Fund" aimed at education, workforce readiness, healthcare access, and local economic resilience, without exposure to standard shareholder-primacy suits.
Stage Focus
AMP does not fit a conventional early-stage-only or growth-only mold. Its checks have appeared in massive seed rounds (Periodic Labs' $300M seed), Series B rounds (Black Forest Labs, OpenRouter), and mega growth rounds (Anthropic's $30B Series G, River AI's $1.1B round). In practice AMP writes large checks wherever it can secure a position with frontier labs it believes are compute-constrained, spanning seed through late growth stage.
Check Size
Exact per-deal check sizes are not consistently disclosed. Some reporting attributes a roughly $300M allocation to AMP's participation in Anthropic's Series G, though this figure has not been independently confirmed via primary sources. Given the deal pattern (co-leading $300M-$1.1B rounds), individual checks are likely in the tens to hundreds of millions of dollars. This research intentionally leaves checkSizeMin/Max unset given the lack of verified per-deal figures.
Lead Tendency
AMP has both led/co-led rounds (Black Forest Labs Series B alongside Salesforce Ventures; River AI's $1.1B round alongside General Catalyst; a reported lead role in Periodic Labs' 2026 round) and participated as a significant-but-non-lead investor (Anthropic Series G; OpenRouter Series B). Lead tendency is best characterized as "both."
Recent Activity
AMP has been highly active since its 2026 founding: a ~$300M participation in Anthropic's $30B Series G (reported February 2026), co-leading Black Forest Labs' $300M Series B in December 2025, being reported as leading a $500M+ round in Periodic Labs at a $7.5B valuation (May 2026), participating in OpenRouter's $113M Series B (May 2026), and co-leading a $1.1B round in River AI (August 2026, alongside General Catalyst). The firm reportedly secured $1.3B in capital commitments within its first eight weeks from institutions, pension funds, and sovereign funds, with capital partners publicly acknowledged by founder Anjney Midha as including NEA, Andreessen Horowitz, Y Combinator, and StepStone Group.
Portfolio Highlights
Confirmed or credibly reported portfolio/investment relationships include Anthropic (frontier LLM lab), Black Forest Labs (frontier visual/image-generation AI, Germany), Periodic Labs (AI-for-science / materials discovery), OpenRouter (AI model routing/inference infrastructure, where Midha also sits on the board), River AI (open AI stack / fine-tuning and serving infrastructure, founded by xAI co-founder Igor Babuschkin), and Mistral (frontier LLM lab, France) per founder commentary, though the timing/vehicle of the Mistral relationship is less clearly documented than the others.
Team
- Anjney Midha, Founder & CEO — Former general partner at Andreessen Horowitz focused on AI, infrastructure, and open-source; previously at Discord; holds a bioinformatics master's from Stanford Medicine.
- An engineering co-founder referred to publicly only as "Seb," who built Google's Borg/PBorg/GQM cluster-scheduling systems, leads AMP's infrastructure/Grid engineering alongside another Google alum ("Mihai"). Full surnames were not confirmed in available sources, so they are not submitted as structured team records to avoid misattribution.
Decision Process
Not publicly documented. Given the small, founder-led structure, it is likely a tight partnership/solo-GP-adjacent process, but this is not confirmed and is left as "unknown."
Founder Preferences
Not explicitly published. Inference from the portfolio (Anthropic, Periodic Labs, Black Forest Labs, River AI) suggests a strong preference for technical, research-caliber founding teams (often ex-OpenAI, ex-Google DeepMind, ex-xAI) building frontier-capability AI labs rather than application-layer companies.
Geographic Focus
Global frontier AI labs, with confirmed activity in the US (Anthropic, OpenRouter, River AI, Periodic Labs) and Europe (Black Forest Labs in Germany; reported Mistral relationship in France).
Headquarters & Scale
AMP is generally reported as San Francisco-based, consistent with its founder's prior base at Andreessen Horowitz, though no source in this research confirmed a specific street address. The firm's first fund reportedly closed north of $1.3B in commitments within its first eight weeks, separate from the $500M Public Wealth Fund earmarked for public-benefit spending through 2030.
