Enterprise AI continues reshaping the software landscape, with SoundHound AI (NASDAQ: SOUN) and C3.ai (NYSE: AI) representing two distinct approaches to capturing that opportunity.
SoundHound targets conversational and agentic AI markets, while C3.ai focuses on deploying enterprise AI applications across government and large commercial customers.
Both companies recently reported quarterly results that revealed sharply different growth trajectories, financial conditions and strategic priorities heading into the second half of 2026.
SoundHound posted first-quarter 2026 revenues of $44.2 million, a 52% year-over-year increase, with its core automotive and IoT AI business growing 88% excluding acquisitions.
Management reaffirmed full-year revenue guidance of $225 million to $260 million, reflecting sustained demand across automotive, restaurants, financial services, healthcare and enterprise customer service verticals.
The company’s planned acquisition of LivePerson represents its most significant near-term growth catalyst, with management projecting a long-term revenue opportunity of roughly $500 million through cross-selling voice AI, digital messaging and omnichannel customer engagement solutions.
SoundHound also introduced OASYS during the quarter, a self-learning agentic AI platform designed to automatically create, orchestrate and improve AI agents while leveraging the company’s proprietary speech foundation models.
Management expects OASYS to reduce reliance on third-party large language models, lowering operating costs and improving scalability over time, though persistent operating losses and LivePerson integration risk remain material concerns for investors.
C3.ai, by contrast, reported fourth-quarter fiscal 2026 revenues of $51.6 million, with full-year revenues declining to $250.3 million, and management guided fiscal 2027 revenues to $210 million to $240 million, signaling continued top-line pressure.
Founder Thomas Siebel returned as chief executive officer and implemented a broad restructuring that reduced headcount by approximately 35% and targeted roughly $135 million in annual operating cost savings.
C3.ai exited the quarter with more than $670 million in cash, cash equivalents and marketable securities, giving it substantial flexibility to execute its turnaround without requiring additional capital raises.
On a year-to-date basis, SoundHound shares have declined 37.4%, outperforming C3.ai, whose stock has fallen 64.6%, and also faring better than the Zacks Computers – IT Services industry’s 35.5% decline.
Among comparable peers, Palantir Technologies has lost 25.6% year to date, while BigBear.ai Holdings has dropped 41.2%, with none of these companies matching the broader Zacks Computer and Technology sector’s 36.4% gain or the S&P 500’s 23.3% advance.
On a forward 12-month price-to-sales basis, SoundHound trades at 10.63x, slightly below the Zacks Computers – IT Services industry average of 11.05x, while C3.ai trades at a discounted 5.66x, reflecting slower growth and execution uncertainty.
The Zacks Consensus Estimate for SoundHound’s 2026 loss has widened to 18 cents per share from 9 cents over the past 60 days, though analysts still project revenue growth of 38% in 2026 followed by 15.9% growth in 2027.
C3.ai’s fiscal 2027 loss estimate has narrowed to 82 cents per share from 92 cents over the past 30 days, with fiscal 2027 revenues projected to decline 11.5% before returning to 8.7% growth in fiscal 2028.
C3.ai currently carries a Zacks Rank of 3 (Hold), while SoundHound carries a Zacks Rank of 4 (Sell), reflecting near-term caution on SoundHound’s aggressive and capital-intensive expansion strategy.
Despite SoundHound’s stronger revenue momentum and innovative product pipeline, C3.ai’s fortress balance sheet, decisive restructuring actions and improving earnings expectations position it as the lower-risk investment option among the two at this stage.
