Forward-deployed AI engineering
We put engineers inside your business to build AI that connects to the systems you already run, proves its value against a metric we agree in writing, and keeps working after go-live.
30 minutes with a founder. No slides. We reply within one working day.
A pilot that impressed the board in a meeting room often never meets a real customer. It was built on clean sample data. It did not connect to Tally, SAP or the core banking system. Nobody agreed what “good” meant, so nobody could say whether it worked.
Then the vendor moves on, the model changes, and quality drifts with no one watching.
Envisstack exists to close that gap. We build the unglamorous parts that decide whether AI earns its keep: the integration, the evaluation, the security review, the hand-off to a human, the weekly check on quality.
Start with a 2 to 3 week sprint, go straight to the system you already know you need, or begin with the basics that bring customers in.
Our engineers sit with the people who do the work, in your office or on your systems. We build in your cloud account or on your premises, not from a slide deck.
Every engagement has a success metric and an evaluation set agreed in writing before we write production code. If we cannot measure it, we do not ship it.
Hindi, Marathi, Tamil and Hinglish. WhatsApp first. The DPDP Act, RBI, IRDAI and SEBI rules. India-hosted deployments. The Java, SAP and Tally estates you actually run.
Security review, guardrails, observability and cost control are part of the first build, not a later phase.
Every go-live moves to a managed retainer. We measure quality every week and keep improving it.
Small, fixed-price steps. You decide at the end of each one whether to continue.
Workshops with the people who do the work. We find the 20% of the problem that matters and write the business case.
A fixed-price pilot on your real data, scored against an evaluation set agreed up front.
Production integration, security review, guardrails, monitoring, and training for your team.
A managed retainer that measures quality every week and keeps improving it.
Built for how India works
Hindi, Marathi, Tamil, Telugu, Bengali, Gujarati, Kannada and English, including mixed-script Hinglish. We test in every language we ship.
WhatsApp Business, phone, web chat and email, with a clean hand-off to your team.
Tally, SAP, Salesforce, Zoho, core banking platforms, and the legacy databases nobody wants to touch.
DPDP Act 2023 and its 2025 Rules, plus sector rules from RBI, IRDAI and SEBI. Data stays in India where the rules require it.
A lender’s tele-calling team spends most of its day on routine EMI reminders. A voice agent could take the first reminder call in the borrower’s language, confirm a promise-to-pay date, and pass hardship cases to a person. Before building anything, we would agree in writing how we judge it: the share of calls completed without a human, the accuracy of captured promise dates against a listened-to sample, and zero breaches of the lender’s recovery conduct rules.
Plain-language notes on getting AI into production in Indian businesses.
In your own cloud account or on your premises wherever possible, in Indian cloud regions by default. If your regulator requires data to stay in India, it stays in India. We document every place data goes before the pilot starts.
Whichever scores best on your evaluation set at a cost you can sustain. We are not a partner or reseller of any model provider, so we compare commercial model APIs with open-weight models hosted in your environment and show you the results.
You get the full evaluation report, the reasons it fell short, and our honest view on whether more work would change that. You are under no obligation to continue. A clear “no” after six weeks is cheaper than a vague “maybe” after a year.
You do: the code, prompts, evaluation sets, configuration and documentation built for you. Our pre-existing tools stay ours, and you get a perpetual licence to use them inside the system we deliver.
In 30 minutes we will tell you whether AI is the right tool for it, what it would take to prove, and what it would cost. If it is not the right tool, we will say so.
