What It Covers

Jason Lemkin analyzes the 2026 B2B AI landscape, revealing how venture capital and software budgets concentrate in AI-native companies while traditional SaaS struggles, requiring founders to capture AI tailwinds or face market share loss.

Key Questions Answered

• •Venture Capital Concentration: Half of all venture dollars in 2025 went into just four AI deals, with total dollars matching 2021 levels but distributed to less than half the number of companies, making fundraising harder for non-AI startups despite headline valuations.
• •Software Budget Allocation: Gartner projects record 15.2% software spend growth in 2026, but half goes to vendor price increases and 30% to new AI tools, leaving minimal budget for traditional products that don't replace humans or enable massive productivity gains.
• •AI Product Requirements: Products must replace humans, create cyborg-level augmentation like Cursor for developers, or deliver order-of-magnitude productivity gains to capture budget. Adding copilot features without enabling 5x price increases fails to unlock necessary TAM expansion for meaningful growth.
• •Market Share Urgency: Companies that didn't ship agentic AI products in 2025 receive a D-minus grade. Founders have until 2026 to launch AI-native offerings before competitors capture market share, as efficiency ratios show companies like HubSpot increasing revenue per employee 2.6x since 2021.
