Top 7 Emerging B2B and Technology Sub-Sectors Booming Through 2031

Several high-growth sub-sectors across technology, finance, healthcare, and specialized service industries are experiencing massive expansions, with forecasted Compound Annual Growth Rates (CAGRs) scaling well into double digits. These accelerating spaces are largely propelled by enterprise automation, shifting global demographics, the transition to decentralized computing architectures, and the structural rise of the experience economy.

Staying ahead of these macro trends requires targeting the specific, fast-moving niches capturing major venture capital and corporate spending. Highlighted below are the 7 key industries and the distinct sub-sectors positioned to lead global market growth through 2031.

Embedded Finance

This sub-sector covers the integration of financial service tools—such as payment processing, lending infrastructure, insurance, and investment widgets—directly into non-financial software applications, marketplaces, and retail environments. Growth is exploding because it removes friction for consumers, allowing them to complete transactions, split payments, or secure credit at the exact point of need without leaving a brand's ecosystem.

In this Market Glass report, the global market for Embedded Finance is estimated at US $107.3 Billion in the year 2025, and is expected to reach US $877.1 Billion by 2032, growing at a CAGR of 35.0% over the analysis period 2025-2032. Embedded Payment, one of the segments analyzed in the report, is expected to record a 36.6% CAGR and reach US$444.6 Billion by the end of the analysis period. Growth in the Embedded Insurance segment is estimated at 32.9% CAGR over the analysis period.

Edge Computing

Edge computing encompasses the specialized hardware, software, and decentralized infrastructure designed to process data locally—on the device itself or an adjacent local gateway—rather than routing it back to a centralized cloud server. This approach dramatically slashes latency, saves massive amounts of network bandwidth, and secures data privacy.

MarketsandMarkets, in Edge Computing Market by Offering (Hardware, Software, Services), Application (Video Analytics, Asset Monitoring, Automation, IoT Monitoring, Content Delivery), Deployment Mode, Organization Size, Vertical, and Region – Global Forecast to 2031 notes: The global edge computing market is expanding rapidly, with a projected market size rising from USD 111.34 billion in 2026 to USD 317.39 billion by 2031, for a CAGR of 23.3%. Several key drivers and restraints primarily shape the growth of the edge computing market. Drivers include the surge in adoption and practice of Internet of Things solutions across various industries, driving the need for real-time data processing and analytics at the network’s edge. Rising demand for low-latency applications further propels market expansion, alongside strict government regulatory requirements that encourage secure and compliant edge deployments. Additionally, integrating artificial intelligence and machine learning empowers organizations to realize smarter, autonomous operations directly at the edge.

Passwordless Authentication & Identity Management

This specialized security field focuses on modernizing identity verification through biometrics, cryptographic security passkeys, and multi-factor authentication systems that completely eliminate the need for traditional, alphanumeric passwords.

Biometric And Passwordless Authentication Market Outlook 2026-2034: Market Share, and Growth Analysis By Technology, By Component, By Authentication Model, By End-User Industry, by OG Analysis, states that the Biometric And Passwordless Authentication Market is valued at US$39.1 billion in 2026 and is projected to grow at a CAGR of 15.1% to reach US$116.1 billion by 2034. Demand is driven by credential theft concerns, user demand for frictionless login, zero trust architectures, and stronger digital service adoption. Key challenges include privacy debates, spoof resistance requirements, legacy system integration, and uneven acceptance across sectors and age groups. Competition spans identity platform vendors, device makers, cybersecurity firms, card networks, and specialized biometric software providers. Regional demand patterns vary with regulation, buyer maturity, local production depth, and sector adoption behavior.

Cloud-Native Application Protection Platforms (CNAPP)

This cybersecurity sub-sector unifies disparate cloud security tools—including container scanning, cloud security posture management, and runtime infrastructure protection—into a single, integrated platform. It enables enterprise security teams to track and mitigate vulnerabilities continuously from code development to live production.

In Global Cloud Native Application Protection Platforms Market 2026-2030, TechNavio identifies the convergence of AI and autonomous threat remediation as one of the prime reasons driving the global cloud native application protection platforms market growth during the next few years. Also, harmonization of data security posture management and identity governance and transition toward hybrid agentless and agent-based observability architectures will lead to sizable demand in the market. The global cloud native application protection platforms market is forecasted to grow by USD 18274.3 mn during 2025-2030, accelerating at a CAGR of 20.5% during the forecast period.

Remote Patient Monitoring (RPM)

Remote Patient Monitoring includes the connected medical devices, wearable health trackers, and continuous streaming platforms that monitor patient health metrics (like glucose levels, heart rate, and blood pressure) outside of conventional clinical settings.

Bosson Research’s Global Remote Patient Monitoring Market Research Report 2026 (Status and Outlook) notes the global Remote Patient Monitoring market size was estimated at USD 1592.0 million in 2025 and is projected to grow at a compound annual growth rate (CAGR) of 16.90% during the forecast period.

Predictive Supply Chain Analytics

This niche covers the advanced data platforms that leverage machine learning algorithms, real-time IoT tracking sensors, and historical data to forecast logistics bottlenecks, optimize inventory distributions, and anticipate shipping delays.

TechNavio’s Global Supply Chain Analytics Market 2026-2030 forecasts this market to grow by USD 18755.2 mn during 2025-2030, accelerating at a CAGR of 22.6% during the forecast period. This study identifies the rapid evolution toward autonomous agentic decision intelligence replaces passive descriptive analytics dashboards as one of the prime reasons driving the global supply chain analytics market growth during the next few years. Also, enterprise migration toward cloud native analytics platforms enhances cross organizational data synchronization and strategic convergence of corporate financial planning and operational supply chain analytics drives profitability will lead to sizable demand in the market.

Eco-Tourism & Experiential Travel

This consumer-driven sub-sector centers around travel platforms, sustainable accommodations, and curated live events tailored specifically toward environmentally responsible tourism, cultural submersion, and personal wellness experiences.

Maia Research, in Global Ethno Tourism Community Based Eco Tourism Industry Trends Analysis Report 2025, Forecast to 2033 (Broken Down by Type, End User, Regional Analysis, and Competitive Landscape) projects this market at USD 14351.31 Million in 2025 and is expected to reach USD 60890.6 Million in 2033, growing at a CAGR of 19.8% from 2025 to 2033.
