Where the Next Trillion Dollars in Enterprise AI Would Come From

Companies like Scale AI and Surge AI generate approximately a billion dollars annually by teaching AI systems what quality looks like, not through foundation models or GPU sales, but via data infrastructure and human-in-the-loop systems.

§01

Models are general. Value is specific.

AI doesn't fail from lack of intelligence but from insufficient context, judgment, and domain intuition. Financial AI must think like bankers and reason like analysts. This translation layer emerges from people experienced within those workflows, not larger models. Enterprise AI's next trillion dollars unlocks through this mechanism.

§02

Why we started gAI Ventures

Amit Goel (Medici founder, NYC unicorn) and co-founder Kushal Prakash (ex-AI researcher, Forbes 30 Under 30) launched gAI Ventures with a hypothesis: vertical AI differs fundamentally. Winners require deep domain expertise, proprietary quality data, workflow embedding, strong engineering, and genuine industry infrastructure, not just AI applications.

The team built deliberately:

  • Consumed dozens of research papers
  • Developed multiple AI-native products (FastTrackr AI, Swik AI, Stella AI)
  • Achieved #1 Product Hunt ranking globally
  • Launched products serving 13+ customers within 6–7 months
§03

AI works best when humans stay in the loop

Thomas Dohmke notes: "80% of code will be written by Copilot soon. Developers won't be replaced." Goldman Sachs' David Solomon observed AI generates "95% of IPO prospectuses; the final 5%" requires human judgment.

The pattern: AI accelerates execution; humans provide judgment.

§04

What this looks like in practice

FastTrackr.AI example (wealth management):

AI capabilities:

  • Join meetings
  • Process documents
  • Extract structured data
  • Update CRMs
  • Draft follow-ups

Advisor responsibilities:

  • Build trust
  • Understand client nuance
  • Make judgment calls
  • Navigate risk

Magic emerges through reallocation of human attention, advisors gain client time while backend friction disappears.

Harvey AI example (legal):

AI handles:

  • Contract drafting
  • Clause analysis
  • Regulation summaries

Lawyers provide:

  • Judgment application
  • Negotiation
  • Risk assessment

Impact: Associates save 30–40% drafting time; partners focus on strategy.

§05

AGI is not around the corner

Andrej Karpathy emphasizes AI lacks curiosity, intrinsic motivation, and cultural understanding. Autonomous agents frequently fail. Today's solution: chunked autonomy with human supervision.

§06

Building AI products is 10% models, 90% messy workflows

Two tax AI startups launched simultaneously with identical models. Within six months, one gained 10,000 users; the other had 12. The difference: one founder invested in comprehensive pipelines (intent detection, retrieval, structured outputs, reasoning scaffolds, guardrails) while the other dumped everything into context windows.

Product engineering, not AI magic, created this disparity.

§07

Why vibe-coding won't build serious companies

Tools like Cursor and Lovable assist development but don't produce enterprise-grade products. Output quantity differs from output quality. Without domain depth, rigorous engineering, and workflow embedding, developers create demos rather than companies.

§08

Vertical AI needs more upfront work

Vertical AI demands:

  • More people
  • Greater integration complexity
  • Extended timelines
  • Forward-deployed engineers
  • Security and privacy reviews
  • Trust development

Incumbents cannot simply rebrand existing SaaS as AI. Winners rebuild from first principles, tightly connecting model capabilities to actual problems.

§09

The real revolution

This transformation focuses on knowledge transfer, converting domain-specific human wisdom into general intelligence useful within spreadsheets, hospital systems, or logistics dashboards. This layer quietly powers the AI expansion.
