AI automation studio

We don't drop AI into your process. We rebuild the process.

what we build

Three shapes of build. One outcome.

Hours back, errors down, work that used to be someone's job just running on its own.

AI agents

Agents that take a job description, an SOP, or an inbox and actually do the work. Research, triage, drafting, follow-ups, data entry. Trained on your playbook and your data, not a generic chatbot fine-tune.

Workflow automation

End-to-end pipelines for the work that hits your team every day. Order processing, lead routing, billing reconciliation, report generation. Real error handling, audit logs, and human approval points exactly where you want them.

Integrations and data sync

Custom integrations between the tools that don't talk to each other. Two-way sync, conflict handling, retries, audit logs. The kind of plumbing that looks invisible until you notice nobody is exporting CSVs anymore.

how we work

Identify, develop, adopt.

Three steps from first call to a system the team actually uses.

01

Identify

We start by watching how your team actually works. Where time leaks, where work piles up, which steps get redone because the previous step was unreliable. The output is the 5% of opportunities worth building, ranked by hours saved per week.

02

Develop

Plans are short, iteration cycles are short. Solutions slot into the tools your team already runs: n8n, Make, Zapier, custom Python. Built right the first time so they hold up in production from day one.

03

Adopt

We sit with the operators, train them, tune the system to how they actually use it, and stay close until the new way is the only way. By the time we step back, it is just how work gets done.

Why teams pick calmstack.

Fixed scope, fixed price

You know the cost and the deliverable before we start. No open-ended retainers.

Built on your stack

We work with the tools you already pay for. No forced migration to something new.

You own everything

Code, documentation, and credentials are yours. There is no vendor lock-in with calmstack.

A human stays in the loop

Automation handles the repetitive part. You keep the judgment calls and the final say.

in their words

What clients say about the work.

I've been working with developers for over a decade now and Kunal is the single best developer I've worked with. An absolute pleasure to work with, he not only provides exceptional technical ability in automation and AI, but also goes above and beyond to communicate throughout the project. He's also personally a pleasure to work with and will find a creative solution to any technical problem you have. If you get a chance to work with Kunal please jump at the opportunity, he is a gem.

Kunal Barve

Founder, automation engineer

Builds AI agents and automation systems on n8n, Make, Zapier, and custom Python. Dozens of bespoke API integrations shipped across operations, sales, and content workflows.

Anyone can chain a few APIs together with a no-code tool. That is not what we do. We build engineered systems, custom-coded and properly logged, designed to run unattended for years and survive the messy real-world data a demo never has to deal with.

6+ hrs/day 6+ hours of manual work cut every day for Bunsters Worldwide, an Australian beverage company. Around $17,000 a year saved in labour cost.
$210 to $25k AgentLink, a founder-led real-estate platform, went from $210 to $25,000 MRR in a single month after agentic systems for client matching, payments, and inbound communications shipped.
30 hrs to 15 min B2B content research pipeline rebuilt for Kyle. Research, source-checking, and outline drafting handled end-to-end, with quality the team signed off on.
