The founders

Hi, we're Ben and Billy.
We built Calso.

We're a two-person team in Melbourne. Between us we built the phone agent, the supplier ordering, the admin automation, and the website you're reading right now. No outsourced dev team, no enterprise org chart — just the two of us and one stack.

Who's behind Calso

Two builders, one product.

Co-founder

Ben Adler

Builds Calso end-to-end — product, architecture, code, copy, ops. Grew up around small businesses in Melbourne and got tired of watching owners drown in admin after close. Calso is the thing he wished existed.

Co-founder

Billy Watson

The other half of Calso. Builds alongside Ben on product, design, and the messy operational details that turn a tech demo into something a real venue can actually use day to day.

Why Calso

Aussie hospo doesn't need another dashboard. It needs its phone answered.

The cafes, restaurants and bakeries we know run on ten open tabs, a phone that won't stop ringing during service, and an owner who does the supplier calls, the ordering, the reviews and the admin at 11pm after close. The “AI” most of them see pitched is a US SaaS tool with eight tiers, dashboards nobody opens, and a New York accent on the phone.

Calso is the opposite. One line, Australian voice, speaks like a local. It picks up the phone, takes the booking, rings the supplier, sends the recap, chases the review. No seats, no tiers, no per-minute charges. Built for venues, not for enterprise procurement.

We ship Calso end-to-end ourselves — product, architecture, code, copy, ops. Modern small-team toolkit, AI pair-programming included. But the decisions, the direction and the accountability are ours. If a venue needs Calso to behave differently or something breaks at 10pm, you're not logging a ticket with a helpdesk in another timezone — you're talking to the people who built the thing.
