We build AI agents that file invoices.
Binjaw is an AI studio in Munich and Mangalore. ChatGPT drafts an email when you ask — our agents do the whole job unasked: filing invoices, answering the inbox, running 24/7 inside your systems. Built for teams in India and Germany as 2-week sprints or 4–10 week custom builds, advised monthly — fixed scope, priced before we start, and you own every line of code.
What is Binjaw?
A sole-proprietor AI studio
Binjaw is a sole-proprietor AI studio building for teams in India and Germany. Three focused services — two-week automation sprints, fixed-price custom AI builds, and monthly technical advisory — plus a growing catalog of practical AI tools. The difference from ChatGPT: our agents act on their own schedule, running your workflow 24/7 instead of waiting for a prompt. Every engagement is priced in writing before work starts: no hourly billing, and a missed final milestone is never charged. Self-funded. No decks.
Sprint. Build. Advise.

Tools you can
actually use.
The software we ship publicly. Each tool at binjaw.co/tools solves one specific problem — built in-house, free where we can, open about what’s live vs. what’s coming.

Notes on practical AI, delivery tradeoffs, and what we’re shipping lately. Short pieces, written in the open.
AI that ships, not AI that transforms
Small businesses don't need an 'AI transformation.' They need one workflow automated this month. Here's the difference — and why we built Binjaw around it.
ReadRAG without the hype — what actually works for small teams
Retrieval-augmented generation is the most over-pitched AI technique of the last two years. Here's what a minimal, useful RAG setup looks like for a non-enterprise team.
ReadWhy we fix the window, not the scope
Most AI engagements fail on timeline, not on specs. Fixing the delivery window forces smaller, shippable scopes — and surfaces the real constraint earlier.
ReadRAG vs fine-tuning — choosing the cheaper one
Fine-tuning is a fine tool. It's also the wrong one for almost every small-business use case. Here's the decision tree we actually run through.
ReadWhat we decline (and why)
A short list of engagements Binjaw says no to — so the scope is clear before the first call. No hidden terms, no bait-and-switch.
ReadPrivacy when you can't self-host
Most small businesses can't run their own model infrastructure — and shouldn't. Here's how we handle privacy when the model lives on someone else's GPU.
ReadTwo things we won’t compromise on.
Not testimonials — the operating principles we sign engagements against. If one of these becomes impossible mid-project, we renegotiate or refund.
“Fixed scope engagements ship in the quoted window or we don’t charge the final milestone. If we misjudged, that’s on us — not on you.”
“You keep the code. Every line we write lands in your repository, with an architecture doc and a runbook. If Binjaw disappears tomorrow, your system still runs.”
Good questions,
straight answers.
