Kong Inc.
Kong sells API gateway infrastructure that routes traffic between apps, services, and now AI models.

The call
Kong's core gateway business looks safe on install base alone, but its AI growth bet is racing open-source and AI-native rivals that shipped first.
Kong sells software that sits between apps and the APIs they need, protecting and managing traffic. This core business is difficult for competitors to dislodge because customers have woven Kong deep into their systems, and big cloud companies like Google and Amazon have their own competing products but are not winning Kong's customers back. However, Kong is now trying to grow by adding AI features like managing connections between AI tools and businesses. The problem is that smaller, free competitors like LiteLLM and Zuplo are already shipping AI gateway products from the ground up and winning customers, while Kong bolted AI features onto its older system. The question that will decide Kong's future is whether its AI gateway business becomes a real, profitable product line or just a minor add-on that doesn't move the needle, a picture that will likely become clear over the next one to two years as customers choose sides and growth numbers either strengthen or stall.
Why
01
AI pressure: LiteLLM, Zuplo, OpenRouter. Open-source LiteLLM (40K+ stars) and AI-native Zuplo offer free or purpose-built AI gateways, undercutting Kong's bolted-on MCP support. Could AI do the core job? Only partly.
02
Bigger players: Google Apigee, Salesforce MuleSoft, AWS API Gateway. These lost ground to Kong for years and show no sign of reversing it, even as they add their own AI features. Could a giant copy it? Probably.
03
What protects it. 37,000+ companies already run Kong Gateway in production, and ripping out infrastructure that routes live traffic is expensive and risky.
What would change this call
Kong announces named enterprise logos for its AI-gateway/MCP or Metering & Billing product by 2027. shows the AI-pivot is gaining real paying adoption beyond the core gateway business.
Kong's net revenue retention rate is reported below 110% in any future disclosure. would indicate core installed-base expansion is weakening.
LiteLLM, Zuplo, or Tyk announce enterprise customers switching from Kong for AI-gateway/MCP use cases. would confirm Kong is losing the new AI-connectivity growth vector to native rivals.

Key numbers
- $100M+ ARR
- ~130 enterprise customers, $769K avg ACV
- $175M raised at $2B valuation
Named risks
- Kong's AI/MCP gateway features described as plugin-bolted, not natively architected, per 2026-01-04 critique.
- Open-source LiteLLM and OpenRouter could commoditize the AI-gateway feature set Kong is betting growth on.
- Only 2-3% of open-source install base converts to paid Konnect contracts per analyst estimate.
- No new funding round disclosed since November 2024 despite continued global office expansion.
- Kong Gateway Enterprise 3.11.x end-of-life migration through mid-2027 could affect renewal and churn.
