Most existing solutions rely on static or delayed data sources, which creates a lag in responding to user behavior. Systems lack the ability to capture and process real-time actions, environmental changes, and contextual signals. Dynamic personalization is rarely a core architectural principle, which results in “average experience” outputs that fail to meet a user’s immediate needs.
Cutting in & Opportunity
Build a data platform capable of continuously ingesting and processing multi-source real-time signals (behavioral data, sensors, location, third-party APIs)
Integrate a decision engine at the infrastructure layer so that content, interfaces, and functionalities adapt automatically to the user’s current state
Create a cross-application personalization protocol that allows multiple products to share a dynamic user profile for precise context matching
Focus on API-first models that allow seamless integration of personalized video, whether for ecommerce try-ons, interactive storytelling, or AI-driven social experiences. Additionally, tools that simplify video prompt design and content moderation will reduce friction.
Innovate around personalization algorithms and content governance systems to manage scale and quality.
Positioning as a middleware layer between raw video generation models and end-user applications unlocks broad use cases.
Case in Point
Startups like Synthesia have made strides by enabling AI-generated video avatars for training and marketing. Runway provides creators with accessible video editing powered by generative AI.

Replacing Government Consulting:
Automating Bureaucracy and Cutting Waste
Governments globally spend billions annually on consulting firms to navigate complex regulations, procure approvals, and manage compliance. This creates an entrenched industry with high costs and slow processes, limiting agility and innovation.
Challenge
Government workflows rely heavily on human experts for knowledge-intensive tasks that are repetitive and rules-based. Consulting firms act as intermediaries, but their involvement drives up costs and creates dependency. Existing software solutions often remain bespoke, fragmented, and lack scalability.
Cutting in & Opportunity
Develop AI-powered platforms that leverage large language models to automate regulatory interpretation, policy compliance checks, and government procurement processes. These platforms should embed up-to-date legal frameworks and provide transparent audit trails to increase trust. The focus is on transforming opaque bureaucratic workflows into efficient, accessible, and scalable systems.
Opportunities exist in building domain-specific LLMs tuned for various government functions, integrating with public data sources, and creating user-friendly interfaces for officials and contractors.
Startups can also create feedback loops to continually improve AI accuracy and relevance based on regulatory changes.

AI-Native Enterprise Software:
Reshaping Workflows and Value Capture
Enterprise software giants emerged by harnessing cloud computing to offer vastly improved, scalable products that incumbents struggled to replicate. AI now presents a similarly transformative wave, embedding intelligence deeply into core workflows rather than treating it as an add-on.
Challenge
Existing enterprise software often functions as a system of record, tracking human activity but lacking intelligent assistance. Legacy vendors face inertia and complexity in redesigning products to integrate AI meaningfully. Customers expect faster, more accurate, and context-aware tools, but widespread adoption demands trust and seamless integration.
Cutting in & Opportunity
Focus on building AI-native applications that augment employee productivity across sales, HR, finance, and operations by embedding AI assistants that proactively surface insights, automate routine tasks, and continuously learn from interactions.
Position products not as mere incremental upgrades, but as entirely new workflows that fundamentally redefine how work is done, distinct from legacy systems.
Developing vertical-specific AI models trained on domain data can differentiate offerings. Startups can also capture value by making AI explainable and compliant with enterprise security standards. The goal is to become indispensable in day-to-day operations, shifting cost centers into profit drivers.
Case in Point
Companies like Gong apply AI to analyze sales conversations for coaching and forecasting. UiPath automates workflows with AI-powered robotic process automation. These illustrate how AI can move beyond simple automation to strategic business enablers.
Why This Matters
The next generation of enterprise software will be defined by AI’s ability to transform work itself.
Startups that embrace this from day one avoid legacy constraints and capture disproportionate value by rewiring how businesses operate at scale.
Lean Team Productivity Metrics:
Redefining Scale Through Revenue per Employee
The era of sprawling corporate behemoths is giving way to lean, nimble teams powered by AI and cloud infrastructure. These small groups can achieve outsized impact by focusing relentlessly on efficiency and execution.
Challenge
Traditional companies grow headcount to scale, which often dilutes focus and slows decision-making. High costs and internal politics sap energy. For startups aiming to build category-defining businesses, balancing rapid growth with maintaining a high-agency culture remains difficult.
Cutting in & Opportunity
Design companies that optimize for revenue per employee, leveraging AI tools to automate routine tasks and amplify human judgment. Building “10-person, $100 billion” companies means rethinking org structure, workflows, and talent acquisition to maximize individual leverage.
