5. ServiceNow, Inc. (NYSE:NOW)

ServiceNow, Inc. (NYSE:NOW) is one of the fastest-growing agentic AI stocks to buy. However, investors still want proof that the AI narrative will translate into durable upside for the company. Despite the strong results, Stifel cut its price target on ServiceNow to $135 from $180 on April 2, 2026, while maintaining a Buy rating, citing weaker channel checks and a very weak U.S. federal spending environment, a reminder that even strong agentic positioning does not make the core business immune to execution and demand concerns.

In late January, the company reported fourth-quarter subscription revenue of $3.47 billion, up 21% year over year, while total revenue rose 20.5% to $3.57 billion. Current remaining performance obligations, a key forward-looking software metric, climbed 25% to $12.85 billion.

ServiceNow also said Now Assist net new ACV more than doubled in the quarter. The agentic angle became more explicit on January 20, 2026, when ServiceNow expanded its collaboration with OpenAI to power agentic AI experiences across enterprise workflows.

The company said the partnership would help customers access frontier-model capabilities inside ServiceNow’s platform, with use cases ranging from real-time voice agents to more autonomous IT and workflow orchestration. ServiceNow said it already powers more than 80 billion workflows annually, which is what makes its bull case stronger than most: it is trying to layer agents onto an already entrenched enterprise workflow system rather than starting from scratch.

ServiceNow, Inc. (NYSE:NOW) provides a cloud-based AI platform that helps enterprises automate and manage workflows across IT, customer service, HR, and other business functions.

4. HubSpot, Inc. (NYSE:HUBS)

HubSpot, Inc. (NYSE:HUBS) is one of the fastest-growing agentic AI stocks to buy.

HubSpot’s agentic push is starting to show measurable traction rather than just branding varnish. In its earnings materials, the company said more than 8,000 customers had activated Customer Agent, which was resolving about 65% of conversations, while more than 10,000 had activated Prospecting Agent, up 57% quarter over quarter. HubSpot reinforced that point on April 2, 2026, when it announced outcome-based pricing for both products starting April 14, arguing that agents had sufficient customer and business context to be priced based on completed results rather than raw usage.

However, this remains an early and crowded category where many projects may not hold up. Gartner said on June 25, 2025, that more than 40% of agentic AI projects could be canceled by the end of 2027 because of rising costs, unclear business value, or inadequate risk controls. That caution matters for HubSpot too: the products look promising, but the long-term payoff still depends on execution and durable customer ROI.

The company reported its fourth-quarter results in early February, posting revenue of $846.7 million, up 20% year over year, while full-year 2025 revenue rose 19% to $3.13 billion. Management said 2025 was shaped by momentum in its “agentic customer platform,” with AI adoption accelerating as Breeze Customer Agent and Breeze Prospecting Agent delivered outcomes for customers.

HubSpot, Inc. (NYSE:HUBS) provides cloud-based software for marketing, sales, customer service, content management, operations, and commerce through a unified customer platform.

3. Appier Group, Inc. (OTC:APPIF)

Appier Group, Inc. (OTC:APPIF) is one of the fastest-growing agentic AI stocks to buy.

The most interesting part about Appier is that the company is not merely describing itself as an AI software vendor in the vague, overused sense. The company now explicitly brands itself as an “Agentic AI-as-a-Service” provider, and on March 16, Appier released a whitepaper focused on autonomous marketing, framing agentic AI as a system for planning, execution, and continuous optimization rather than simple assistance. A few days earlier, on March 11, it announced new research aimed at improving the reliability of agentic AI systems through a risk-aware decision framework. That lines up with the company’s push to automate real business decisions inside marketing workflows.

In mid February, Appier reported fiscal 2025 revenue of JPY 43.7 billion, up 28% year over year, and said its fiscal 2026 guidance implies another 24% increase to JPY 54.0 billion. The company said the outlook was driven by advancements in Agentic AI and dual-engine market penetration.

Appier Group, Inc. (OTC:APPIF) provides AI software for marketing, advertising, and customer engagement, with products built around data-driven targeting, personalization, and automated decision-making.

2. SoundHound AI, Inc. (NASDAQ: SOUN)

SoundHound AI, Inc. (NASDAQ: SOUN) is one of the fastest-growing agentic AI stocks to buy.

On April 9, 2026, SoundHound announced a partnership with Associated Carrier Group to bring agentic AI to telecom customer service and employee experience. The deal adds another enterprise vertical to SoundHound’s AI Agent Platform and supports the company’s broader push beyond voice assistants into systems designed to handle more of the actual service workflow. Earlier, on February 24, SoundHound also introduced Sales Assist Agent, a real-time tool for retail teams, indicating a broader commercial rollout of agentic products across industries.

SoundHound entered 2026 with strong momentum. In late February, the company reported full-year 2025 revenue of $168.9 million, up 99% year over year, while fourth-quarter revenue increased 59% to $55.1 million. It also said it closed a record number of enterprise deals in the quarter and forecast another year of growth as businesses shift spending toward AI-native platforms.

SoundHound AI, Inc. (NASDAQ: SOUN) provides voice, conversational, and agentic AI software for customers across automotive, restaurants, retail, telecom, and other enterprise markets.

1. Palantir Technologies Inc. (NASDAQ: PLTR)

Palantir Technologies Inc. (NASDAQ: PLTR) is one of the fastest-growing agentic AI stocks to buy.

Palantir’s product releases in March reinforced its push into agentic AI. On March 31, 2026, the company said the AIP Analyst would become generally available starting the week of April 13. Palantir describes the product as an interface for agentic workflows that allows users to query ontology data in natural language, with the system autonomously searching data, transforming it, and generating summaries and visualizations. Earlier, at AIPCon 9 on March 12, Palantir also highlighted customer deployments across industries, suggesting that adoption is moving beyond experimentation and deeper into operational use.

Palantir’s case starts with scale and acceleration. In early February, the company reported fourth-quarter revenue of $1.406 billion, up 70% year over year, while U.S. commercial revenue rose 137% to $507 million. Full-year 2025 revenue reached $4.475 billion, and Palantir guided for 61% revenue growth in 2026, with U.S. commercial revenue expected to grow 115%. Those numbers stand out because only a few software companies of this size are still growing anywhere near that pace.

Palantir Technologies Inc. (NASDAQ:PLTR) develops software platforms for government and commercial customers focused on data integration, analytics, and operational decision-making.
