Wall Street fixates on chipmakers and hyperscalers, but the harder problem in AI is implementation. Getting agentic workflows, orchestration platforms, and AI-native applications into Fortune 1000 environments is where projects stall, and where specialist services firms quietly get paid. With corporate IT budgets cautious, several implementation plays trade under $15: real AI revenue, real customers, small-cap value pricing.
Four stocks under $15 worth examining as under-the-radar enterprise AI implementation plays.
Grid Dynamics (NASDAQ: GDYN)
Grid Dynamics (NASDAQ:GDYN) builds agentic systems for large enterprises with a recently launched GAIN platform suite covering commerce, software development, risk, and physical AI. Shares sit at $7.13, down 45.61% over the past year as IT spending pauses dragged the stock into small-cap value territory.
Q1 2026 revenue came in at $104.10 million, with AI revenues reaching 29.3% of total revenues and full-year 2025 AI revenue clearing $90 million at 30% year-over-year growth. The balance sheet is essentially debt-free with $327.47 million in cash, and analysts carry a $9 target with six buy ratings and zero sells. CEO Leonard Livschitz called “2026 a pivotal year for the accelerated adoption of our AI offerings”. The bull case: a pure-play AI implementation services business at roughly 1.4x sales, with hyperscaler partnerships and a top-five customer roster now fully diversified away from retail.
Risks include client concentration and gross margin compression to 34.8%. For investors wanting AI exposure without hardware-layer multiples, Grid Dynamics is the clearest architecture play.
C3.ai (NYSE: AI)
C3.ai (NYSE:AI | AI Price Prediction) sells the C3 Agentic AI Platform and industry applications, with heavy federal, defense, and aerospace exposure. Shares trade at $9.29, down 59.13% over a year after Q3 FY26 revenue collapsed 46.1% to $53.26 million, missing expectations.
The bull case is a turnaround. New CEO Stephen Ehikian is six months into restructuring expected to generate roughly $135 million in annual operating expense savings, including a 26% workforce cut. Federal, defense, and aerospace bookings rose 134% year over year and made up 55% of total bookings, while subscription revenue is now 90% of the mix. Ehikian says C3 is “uniquely positioned to win in Enterprise AI” as a “more agile, more disciplined, and more accountable organization.”
Risks are clear: cash burn accelerated to negative $56.2 million in free cash flow, gross margin compressed to 17%, and a securities class action is pending. For aggressive investors, federal momentum and cost cuts offer a credible recovery angle at a deeply reset price.
BigBear.ai (NYSE: BBAI)
BigBear.ai (NYSE:BBAI) runs an AI-powered decision intelligence platform for national security, defense, and border operations, recently bolstered by Ask Sage and CargoSeer acquisitions. Shares trade at $4.18, placing the company in small-cap territory after a volatile year.
The setup is a balance sheet transformation. BigBear.ai ended 2025 with $462 million in cash and investments after raising $693 million and reducing debt by more than 90%. The $250 million Ask Sage acquisition adds a generative AI platform with 100,000+ users across 16,000 government teams. Management guided FY26 revenue to $135 million to $165 million, with a backlog above $400 million. CEO Kevin McAleenan said the company is in “the strongest financial position in the company’s history.”
In Q4 2025, revenue fell 38% year over year, gross margin compressed to 20.3%, and the company carries a high beta of 3.051 with material weakness in internal controls. The defense AI tailwind plus a fortress balance sheet makes this a watchable speculative position.
DXC Technology (NYSE: DXC)
DXC Technology (NYSE:DXC) is a global IT services firm whose newly launched OASIS AI orchestration platform positions it to ride enterprise AI transformation budgets. Shares trade at $9.50, down 37.38% on the year.
The valuation case is strongest here. DXC generated $713 million in free cash flow in FY26 against a market cap near $1.55 billion, repurchased $250 million of stock, and trades at a forward earnings multiple of just 4x. Insurance Software & Services grew 7.3% in Q4 and Consulting & Engineering returned to growth at 1.7%. CEO Raul Fernandez framed the OASIS launch as part of repositioning DXC for “the next phase of enterprise IT and AI driven transformation.”
FY27 guidance calls for revenue of $12.11 billion to $12.35 billion with organic declines, and Global Infrastructure Services shrank 10.6% organically. Sub-5x free cash flow on a real AI orchestration story is rare.
A single-digit share price alone is not a reason to buy. Each has clear execution risk, and the AI implementation theme is only as durable as the corporate budgets funding it. Use these profiles as a starting point for your own research.
