I am so excited to show you what we've been building.
@opensurf.ai — automation you can stop thinking about.
(real-time execution; no cuts or speed-ups)

One Monday morning sit-down I joked, "We should totally automate this"
A few days later, Dom casually dropped: "Done"
He’d built a CLI that spun up Estii in a headless browser, logged in as a demo user, navigated through key screens, and captured perfect screenshots in every mode.

By the time we finished Estii, we had 515 end-to-end tests. Some ran for minutes — full onboarding flows, pricing calculators, proposals, integrations.
We even built a semantic layer to help Playwright find everything on the screen. It worked, but it feel like avoidable busy work.

Lesson 1: When two nutters build an enterprise SaaS single- (double-?) handedly, there’s only one way they sleep at night: tests.
Lots of tests.

We have nine Australian Wood Ducklings living with us at the moment (Amy volunteers for Sydney Wildlife)
Just look at the little guys!

Five years ago, Dom and I quit our comfy jobs to build a SaaS product called Estii.
We poured our hearts into it, had a blast, and learnt a ton.
I’m still blown away by the breadth and quality of what the two of us were able to ship in such a short time.
