I’ve been tracking the companies building primitives specifically for agents rather than humans. The pattern is becoming obvious: every capability a human employee takes for granted is getting rebuilt as an API.
Here are some of the companies building for AI agents:
AgentMail — agents can have email accounts
AgentPhone — agents can have phone numbers
Kapso — agents can have WhatsApp numbers
Daytona / E2B — agents can have their own computers
monid.ai — agents can read social media (X, TikTok, Reddit, LinkedIn, Amazon, Facebook)
Browserbase / Browser Use / Hyperbrowser — agents can use web browsers
Firecrawl — agents can crawl the web without a browser
Mem0 — agents can remember things
Kite / Sponge — agents can pay for things
Composio — agents can use your SaaS tools
Orthogonal — agents can access APIs more easily
ElevenLabs / Vapi — agents can have a voice
Sixtyfour — agents can search for people and companies
Exa — agents can search the web (Google isn’t built for agents)
What’s interesting is how quickly this came together. Not long ago, none of this really existed in a usable form. Now you can piece together an agent with identity, memory, communication, and spending in a single afternoon.
Feels less like “AI tools” and more like the early version of an agent-native infrastructure stack.
Curious if anyone here is actually building on top of this. What are you using?
Also probably missing a bunch - drop anything I should add and I’ll keep this updated.
