Good● Moved fast by only

building what’s needed

Bad● > 4 languages in

production● Complexities in the

interfaces● Boilerplate HTTP

servers● No cross-system

versioning

Making it happen

Launching 1st August

Know what customers want, now make it happen in the app

Most needs are on the frontend

Clojurescript

Need more front-end manpower

Single Page Application: My thinking at the time

Javascript

● Existing frontend is in Javascript

● Humongous community● SPA frameworks: React,

Ember, Flight.js, etc.● All the supporting

libraries that we would need

● Pool of JS talent readily available

Clojurescript

● I am “10x” more productive in Clojure

● Interoperable with Javascript

Built a new feature with Clojurescript for the first time

Startup concerns on Clojure(Script)

CEO Hiring and training

Uncommon stack lessen chances of funding or acquisition

CTO Many libraries are one-person projects

Grow, Grow, Grow

Phase 3

Team

Our job posting in August

“Spokepoint is an MIT startup in Cambridge, MA looking for a Clojurescript frontend contractor (remote possible). Don't know Clojurescript? Doesn't matter. I can help you with that. We are looking for the right person rather than checking a set of skills.

Our web apps are built on Clojurescript, Clojure, Go, and Docker.”

3 out of 3 of our developers with different backgrounds

survived Clojure and ClojureScript

Summary

● Built minimal pieces with pain driven development method

● Clojurescript / Reagent enabled us to deliver quickly on the front-end

● There are developers that want to get paid to use Clojure and Clojurescript
