Selling to the Biggest Companies
F100 buyers actively seeking AI solutions. A 2–3 person team can ship something a Fortune 10 finds useful.
Championed by Harshita Arora & Brad Flora at YC
THE PROBLEM
What needs to be solved
Fortune 100 companies have a paradox: they have the most data, the biggest budgets, and the most to gain from AI — but their internal IT organizations can't move fast enough. A Fortune 10 company might have 200 AI use cases identified but only capacity to build 10. Their procurement teams are actively looking for external solutions and, for the first time in decades, are willing to buy from startups because they recognize that a 3-person AI startup can often deliver better results than their internal teams.
WHY NOW
What changed in 2025–2026
The enterprise AI buying cycle has compressed from 18 months to 3-6 months. CIOs have AI mandates from their boards and allocated budgets that must be spent. The stigma of buying from tiny startups has evaporated — F100 procurement teams now have 'innovation' tracks specifically designed for startup vendors. And AI tools have made it possible for a 2-3 person team to build enterprise-grade solutions (with proper security, compliance, and integrations) that would have required 20+ engineers two years ago.
MARKET CONTEXT
The size of the opportunity
Fortune 100 companies collectively spend $50B+ annually on technology, with AI budgets growing 40% year-over-year. The key insight is that these companies buy outcomes, not technology. If you can demonstrate that your AI solution saves a specific team 2,000 hours per year or reduces error rates by 50%, procurement will find the budget. Average initial contracts range from $200K-$2M, with expansion to $5-20M within 2 years for solutions that prove ROI.
FOUNDER FIT
Who should build this
Founders with any enterprise sales experience have an advantage, but it's not required. What matters more is the ability to identify a specific, quantifiable pain point within a large organization and build a focused solution. Prior experience working at a Fortune 500 company — understanding their internal politics, procurement processes, and IT requirements — is extremely valuable. Technical founders who can also sell (or who partner with someone who can) are ideal.
WHAT YC SAYS
The YC partner perspective
Harshita Arora and Brad Flora challenge the assumption that selling to large enterprises requires a large sales team. Their thesis: in the AI era, a 2-3 person technical team can ship something a Fortune 10 company finds genuinely useful. The key is extreme focus — solve one specific problem exceptionally well for one specific team at one specific company, then expand. The F100 is not one customer; it's hundreds of teams, each with their own budget and pain points.
