who we are, and why a platypus

About Platypus

Platypus is AI booking for phone-only businesses. We make Main Street agent-native: one honest AI phone call makes a business bookable by every AI agent, and every booking after that is a text the owner answers with one letter.

The problem

In one month, every lab shipped a personal agent, and then they all added phone calls. Agents can book an airline or a big-box store, but not the 33 million US small businesses that run on a phone. Those businesses will never build a website agents can use, an API, or an agent of their own. Calling is the stopgap, and every agent that calls a shop starts from zero: the shop learns nothing, and the next agent calls again. Businesses hang up on AI calls, and people still spend 15 to 25 minutes calling around for a single booking.

What we do differently

The call is the onboarding, not the product. Everyone else calls a business every time; we call it once. On that call our voice agent says it is an AI in its first sentence, gets a price and an opening, books the job through our own tools while the owner is still on the line, and asks one question: "Next time a customer's agent needs you, can I text you instead of calling?" A yes is stored with the owner's exact words and the call it came from. From then on, every agent books that business by text.

Consent compounds; calls don't. Every yes becomes supply that any agent platform can route to, and every real booking teaches us what a business charges and how fast it replies.

Who built it

Platypus was built in one day at SpeedHacks, the official speedrun hackathon of SF Tech Week, in San Francisco on October 11, 2026, by a small team working in parallel coding sessions. It is built on Dial for voice calls and owner texts, Darwin for agent search, and Alike for shared memory across the team's coding sessions. The code is MIT licensed on GitHub.

Why the name

A platypus fits no category and lives in two worlds. So does Main Street: on the phone and, now, online. (And yes, the most famous platypus is a secret agent. Ours books oil changes.)

Status

Platypus is a working prototype. The booking core, the MCP gateway, the Darwin integration and the test suite are real; the demo shop's line is a second Dial number answered by Dial's AI, and texts to regular phones wait on 10DLC registration. The README lists exactly what is real and what is mocked.
