AI by Industry

What the World's Best Companies Require From AI.
What We Build For Yours.

Boards no longer ask whether to adopt AI. They ask which decisions it should inform, who stays accountable, and how the return is measured. Choose your sector to see the standard the leaders hold themselves to — and the modules we build, one function at a time, on servers you own.

01Private by default
Models run on the company's own server or a private VPS. Contracts, patient records, ledgers and price lists never leave the building.
02Grounded, cited answers
Every assistant answers from the company's own documents and shows the source. When the answer is not in the data, it says so.
03Human in the loop
AI drafts, ranks, flags and forecasts. A named person approves anything that touches money, patients, contracts or people.
04Measured, not assumed
Each module starts with a baseline (hours, days, error rate, cost) and reports against it. If the number does not move, the module is redesigned.
05Governed
Access control, audit logs, model versioning and a written AI policy aligned to ISO/IEC 42001, ISO/IEC 27001 and India's DPDP Act 2023.
06Owned outright
Source code, models, prompts and data pipelines are handed over. No per-seat licence to us, ever.

Enterprises & Business Management

AI for Business Management, Operations & Strategy

The best-run companies in the world no longer ask whether to use AI. They ask which decisions it should inform, who remains accountable, and how the gain is measured. Our enterprise programme applies that standard to a mid-size Indian business: private models on your own hardware, one module per function, each with a number attached.

What the leaders require

Board-level ownershipAI is a management programme with a sponsor, a budget line and quarterly review — not an IT experiment.
One source of truthTally, CRM, Excel and e-mail feed one governed data layer before any model touches them. Bad data in, confident nonsense out.
Decision rights stay humanPricing, hiring, credit and vendor decisions are recommended by AI and signed by a person, with the reasoning logged.
Return within four quartersEvery module carries a baseline and a target. Leaders expect payback inside a year or a redesign.

Module by module — what AI does, what we deliver, what you measure

What the AI does

Pulls sales, purchase, receivables, payroll and stock from Tally, CRM and spreadsheets every night
Writes the weekly management summary: what moved, why, and what needs a decision
Answers follow-up questions ("why did margin fall in the South region?") with the underlying rows
Flags anomalies — a debtor slipping past 60 days, a cost line growing faster than revenue

What we deliver

Private data warehouse on your server with connectors to Tally, CRM, banks and Excel
Management dashboard with a natural-language question box for directors
Automated Monday-morning board brief by e-mail and WhatsApp
Role-based access so each head sees only their own function

What you measure

Directors spend their review meeting on decisions, not on reconciling three versions of the same number.

Where management companies get breached

Business e-mail compromiseA spoofed MD or vendor e-mail asks accounts to change bank details; the payment goes to the attacker.Our fix: SPF/DKIM/DMARC enforced, payment-change verification policy, AI mail screening for look-alike domains.
Ransomware on the file serverOne phished laptop encrypts shared drives and Tally data; work stops for days.Our fix: Network segmentation, offline versioned backups tested monthly, endpoint hardening and our on-site security appliance.
Insider data exfiltrationA leaving employee walks out with the customer list and price book.Our fix: Data-loss monitoring, USB and cloud-upload controls, access revocation checklist and traffic analysis.
Exposed remote accessRDP or AnyDesk left open to the internet is found within hours by automated scanners.Our fix: VPN or zero-trust access behind the appliance, MFA everywhere, external exposure scan every month.

Cyber Security for Business

Are you paying for your firewall every year?

Most companies rent their security: a per-user, per-year licence that expires, tiers that hide the features you need, and a box that stops protecting you the day the renewal lapses. We build security appliances you own outright — configured for your network, monitored from Chennai, with support that is optional rather than mandatory.

Subscription firewall / UTMPK Rain owned appliance

Cost modelRecurring licence per user or per device, every year, rising with headcountOne-time build and installation. No per-user fee. Optional annual support

What happens at renewalProtection, updates and support stop until you pay againThe device keeps protecting you. Support renewal is your choice

OwnershipHardware is often locked to the vendor's licence; useless without itYou own the hardware, the configuration and the logs

FeaturesIntrusion prevention, web filtering, VPN and reporting sold as separate tiersFirewall, intrusion detection, guest isolation, device control, VPN and logging included

Your dataTraffic metadata and logs frequently sent to the vendor's cloudLogs stay on your device or your server. Nothing leaves without your decision

CustomisationGeneric rules; changes wait on the resellerRules written for your network, your devices and your working hours

SupportTicket queue, often abroadEngineers in Chennai. Alerts to your phone. On-site when needed

Some businesses still benefit from a commercial subscription firewall — large multi-site networks, or where an auditor mandates a specific vendor. We will say so in the assessment rather than sell you a device you do not need.

Defence in depth — seven layers, every one owned by you

We provide: DDoS absorption, bot management and web application firewall on Cloudflare or equivalent; origin shielding so attackers never see your server.

Threat explorer

The attacks your sector faces — and how we stop each one

Your storefront is attacked by software, around the clock, whether you notice or not.

ThreatHow it hits youHow we stop it

01Card testing & payment fraudBots push thousands of stolen cards through your checkout. You pay gateway fees and chargebacks; your merchant account is at risk.Bot management, velocity rules, 3-D Secure enforcement and fraud scoring on every order before capture.

02DDoS on sale dayA traffic flood takes the store offline exactly when you advertised. Revenue and reputation are lost together.Edge DDoS absorption, rate limiting, caching and origin shielding so the flood never reaches your server.

03Account takeoverReused passwords from other breaches let attackers log in, change addresses and use saved payment methods.MFA, credential-stuffing protection, login anomaly detection and session controls.

04Skimming via plugins and scriptsAn outdated plugin or a malicious script copies card details at checkout for months before anyone notices.Plugin and theme audit, content security policy, script integrity monitoring and regular penetration tests.

05Customer database leakNames, phones and addresses exposed through a weak admin login or an unpatched platform.Admin MFA, least-privilege roles, encryption, patch discipline and a breach-response plan.

06Refund and COD abuseCash-on-delivery fraud and refund scams eat margin quietly, order by order.Order risk scoring, address and phone verification, and refund-pattern analysis.

07Price scraping & stock hoardingCompetitor bots copy prices; scalper bots lock inventory in carts.Bot fingerprinting, cart-hold rules and rate limits per session.
