SambaNova Raises $350 Million In Series E Financing

Listen to this article

SambaNova Systems secured over $350 million in a Series E funding round, marking a significant capital infusion amid a competitive AI chip market. The round was led by Vista Equity Partners and Cambium Capital, with participation from Intel Capital and a mix of new and existing investors, reflecting strong interest in SambaNova’s focus on efficient AI inference hardware.

SambaNova’s latest Series E round, exceeding $350 million, represents a strategic pivot toward inference focused AI hardware in a landscape where demand for efficient, scalable AI systems is surging. This comes after a five year gap since the 2021 Series D, during which the company navigated market shifts, including failed acquisition discussions with Intel. The timing aligns with the unveiling of the SN50 Reconfigurable Dataflow Unit (RDU), which emphasizes low latency performance for agentic AI applications, such as real time decision making systems. This round brings SambaNova’s cumulative funding to over $1.48 billion, supporting expanded manufacturing and cloud capabilities to meet enterprise needs in sectors like finance, healthcare, and telecommunications.

Which companies invested in SambaNova Systems?

Vista Equity Partners and Cambium Capital led the investment, signaling confidence in SambaNova’s dataflow architecture as an alternative to GPU-heavy systems. Key participants include Intel Capital (continuing its involvement since 2019), Qatar Investment Authority (QIA), GV (formerly Google Ventures), and new entrants like Battery Ventures, Mayfield Capital, and T. Rowe Price Associates. Existing backers such as BlackRock, Redline Capital, and Atlantic Bridge also rejoined, demonstrating sustained support. This diverse investor base, including sovereign wealth funds and tech focused VCs, highlights the round’s appeal amid broader AI infrastructure investments.

Though not officially disclosed, transaction details point to a post money valuation of approximately $2.24 billion, a decline from the $5.1 billion achieved in 2021. This adjustment reflects broader valuation compressions in AI startups, influenced by competitive pressures and economic factors. The partnership with Intel, including plans for co-selling and AI cloud integration, positions SambaNova to leverage Intel’s ecosystem for broader market access, potentially offsetting valuation dips by accelerating adoption. Customers like SoftBank underscore real world traction for SambaNova’s tech.

The capital will primarily fuel SN50 production ramp-up, SambaCloud expansion, and deeper software integrations for enterprise AI deployments. This focus on inference efficiency, claiming 2.5x higher 16-bit floating point performance and 5x at FP8 over prior generations, aims to address cost barriers in scaling AI agents. By emphasizing heterogeneous data centers with Intel components, SambaNova seeks to capture a share of the multi billion dollar inference market, offering alternatives to Nvidia’s ecosystem.

What is SambaNova Systems?

SambaNova Systems, founded in 2017 by former Oracle executives Rodrigo Liang, Kunle Olukotun, and Christopher Ré, has emerged as a key player in the AI hardware space by developing integrated hardware-software platforms optimized for large scale AI models. The company’s journey began with a seed round of $2 million in November 2017 from Celesta Capital, quickly followed by a $56 million Series A in March 2018 led by Walden International and GV (Google Ventures), with additional backing from Redline Capital and Atlantic Bridge Ventures. This initial funding enabled SambaNova to emerge from stealth mode and focus on its Reconfigurable Dataflow Architecture (RDA), designed to handle both training and inference workloads more efficiently than traditional GPUs.

Building momentum, SambaNova secured a $150 million Series B in April 2019, led by Intel Capital, which marked the beginning of a long term relationship with Intel. Existing investors like GV and Walden participated, bringing total funding to around $208 million at that point. The Series C round in February 2020 raised $250 million, led by BlackRock, with a post money valuation of $2.5 billion. This round included GV, Intel Capital, and others, and was aimed at accelerating enterprise deployments in finance, healthcare, and government sectors.

The peak of SambaNova’s early funding success came in April 2021 with a $676 million Series D led by SoftBank Vision Fund 2, pushing the valuation to $5.1 billion and total funding past $1.1 billion. Participants included Temasek, GIC, BlackRock, GV, and Intel Capital, reflecting high optimism during the AI boom. This capital supported the rollout of the SN30 chip and early customer wins, positioning SambaNova as a potential Nvidia alternative.

However, the subsequent years brought challenges. By late 2025, SambaNova explored a sale amid stalled fundraising, with BlackRock marking down its stake by 17% and an implied valuation drop to around $2.13 billion, a 57% decline from 2021. Acquisition talks with Intel, reportedly at $1.6 billion including debt, fell through, leading to the current collaboration instead. This shift underscores broader market dynamics, where AI chip startups face intense competition from Nvidia, which dominates with over 80% market share in AI accelerators.

The February 2026 Series E round, exceeding $350 million, revives SambaNova’s trajectory without a full exit. Led by Vista Equity Partners and Cambium Capital, it features a broad coalition: Intel Capital, QIA, GV, Battery Ventures, T. Rowe Price, Mayfield Capital, Assam Ventures, Gulf Development Public Company Limited, Saudi First Data, Seligman Ventures, and returning investors like A&E, 8Square, Atlantic Bridge, BlackRock, Nepenthe, Nuri Capital, and Redline Capital. The round’s structure, split into E-1 ($300 million at $30.99 per share) and E-2 ($44.87 million at $21.70 per share), implies a $2.24 billion post money valuation, confirming the downward trend but still substantial for a hardware focused firm.

This funding is inextricably linked to technological advancements. The SN50 chip, an upgrade from the 2024 SN40L, delivers 1.6 petaFLOPS at FP16 and 3.2 petaFLOPS at FP8, with capabilities to interconnect up to 256 accelerators via “multi terabyte per second” links. It targets agentic AI, where systems orchestrate multiple models in real time, offering 5x speed and 3x cost savings over rivals. CEO Rodrigo Liang emphasized shifting from model size to deployment efficiency: “AI is no longer a contest to build the biggest model… the real race is about who can light up entire data centers with AI agents that answer instantly.” Intel’s EVP Kevork Kechichian highlighted the need for GPU alternatives, while investor quotes from Cambium’s Landon Downs and Vista’s Monti Saroya praised the SN50’s fit for latency sensitive applications.

The Intel partnership is multifaceted: it includes AI cloud expansion on Xeon infrastructure, integrated systems combining SambaNova RDUs with Intel CPUs, GPUs, networking, and storage, and joint go to market efforts. Intel’s strategic investment accelerates this, targeting heterogeneous data centers to tap into the inference market, estimated at multi billions. This collaboration follows Intel’s failed buyout attempt, influenced by CEO Lip-Bu Tan’s dual role as SambaNova’s chairman since his early investment.

In the broader market, SambaNova competes in a $17.6 billion-funded AI chip startup ecosystem, where upstarts like Grok (xAI’s chip efforts) and others challenge Nvidia. Inference, comprising 90% of AI compute costs, is a high growth area, and SambaNova’s pivots, such as SambaManaged (July 2025) and AWS Marketplace integration (May 2025), address this. Customers including SoftBank validate traction, but challenges persist: Nvidia’s ecosystem lock-in, supply chain issues, and the need for proven scalability.

Looking ahead, the funding positions SambaNova for growth in agentic AI, potentially leading to an IPO or further rounds if SN50 adoption accelerates. Valuation recovery could hinge on revenue milestones, with the Intel tie-up providing distribution leverage. Overall, this round signals resilience in a volatile sector, emphasizing efficiency over hype.
