Funding Stage Trends

Seed Stage ($1-5M)

What's working: Strong founding teams with clear vision and early customer traction. Pre-product raises are rare unless the team has exceptional pedigree.

Typical metrics: 5-10 design partners, clear problem validation, $10-50K MRR optional but helpful.

Series A ($8-15M)

What's working: Proven product-market fit, $100K+ MRR with strong growth, clear go-to-market motion.

Typical metrics: $1M ARR, 100%+ YoY growth, expanding team from 5-10 to 20-30 people.

Series B ($20-40M)

What's working: Scaled revenue, proven unit economics, category leadership emerging.

Typical metrics: $10M+ ARR, path to profitability visible, expanding to enterprise or new verticals.

Series C+ ($50M+)

What's working: Market leaders with strong competitive moats preparing for eventual IPO or acquisition.

Typical metrics: $50M+ ARR, strong brand recognition, international expansion or major product expansion.

Geographic Trends

San Francisco Bay Area

Still the AI epicenter, but less dominant than before. Advantages: dense talent network, proximity to VCs, AI research talent from universities and big tech companies.

New York City

Strong for AI in finance, healthcare, and media. Growing AI ecosystem with increasing VC presence.

Remote-First Startups

More accepted than ever. Many successful AI startups are fully remote, accessing global talent. VCs still prefer some in-person element for early teams.

Emerging Hubs

Austin, Miami, Denver seeing growth in AI startups. Lower costs, good quality of life, but smaller talent pools.

What's Not Getting Funded

Based on TBPN VC interviews, these categories struggle to raise:

ChatGPT Wrappers

Unless you have massive distribution or a specific vertical moat, thin API wrappers don't interest VCs anymore.

Consumer AI Toys

Fun demos without clear monetization or retention strategies. The "cool AI app" phase is over.

Infrastructure Without Differentiation

Another vector database or LLM hosting platform without clear technical advantages faces tough sledding.

Teams Without AI Expertise

Traditional founders trying to bolt on AI without deep technical expertise struggle versus teams with real AI backgrounds.

Advice for AI Founders Raising in 2026

Before You Raise

• Get paying customers: Revenue talks. Design partners are nice, but VCs want to see people paying.
• Prove unit economics work: Show that margins can be healthy despite AI inference costs.
• Build defensibility: Articulate clearly why you win versus well-funded competitors.
• Demonstrate domain expertise: Show you deeply understand the problem space.

During Your Raise

• Focus on metrics: Growth rate, retention, expansion revenue, gross margins
• Tell the vision story: Where does this go in 5-10 years?
• Address AI-specific concerns: Model risk, data privacy, regulatory considerations
• Show sustainable advantages: Why you, why now, why can't incumbents do this?

Picking Investors

• Prioritize VCs with AI domain expertise
• Look for value-add beyond capital (network, recruiting, strategy)
• Check references from other portfolio companies
• Ensure alignment on exit timelines and growth expectations

Alternative Funding Paths

Traditional VC isn't the only option in 2026:

Bootstrapping

More viable than ever if you can reach profitability quickly. Many AI tools businesses reach $1M+ ARR bootstrapped, then can raise from a position of strength.

Revenue-Based Financing

For companies with revenue but wanting to avoid dilution, revenue-based financing offers growth capital with different terms.

Strategic Investment

Large tech companies investing in AI startups that complement their offerings. Can be great for distribution but watch for conflicts.

Looking Ahead: Rest of 2026

Trends to watch for the rest of 2026:

• Consolidation: Expect acquisitions as larger players buy proven AI startups
• Profitability focus: More companies targeting cash-flow positive versus growth-at-all-costs
