How can the price be fixed for custom work?

Each build covers one workflow with written acceptance criteria. If you want more, it becomes the next fixed build. You never get a surprise invoice.

What does "typically 2–6 weeks" mean?

The AI Feature Sprint is 2 weeks. Agent and voice builds usually take 3–4 weeks, and apps and MVPs 4–6. Your quote gives an exact launch date, and the 25% late refund applies to that date.

Karthik, the founder, scopes every project and reviews every release.

Yes. It goes in your Git repo and your cloud account from day one.

What about AI and hosting costs?

You pay providers like OpenAI, Anthropic, Plivo and your cloud host directly, at cost. The quote includes an estimated monthly running bill.

What if our AI prototype already exists?

Common. On the call we'll tell you honestly whether it can be saved or should be rebuilt.

Do you work with our time zone?

Yes. Work is async with daily updates, plus one or two live calls a week at a time that suits you.

Can I start smaller than $4,997?

Not as a build. The $99 Blueprint gives you a written plan you can take to any developer.

Founder-led build studio · Fixed price · You own the code

Get the AI agent or custom app your team keeps putting off. Fixed price, live in weeks.

We build one production system at a time: an AI agent, voice agent, automation, web app or SaaS MVP. Each one is scoped on a single page, priced $4,997–$9,997 before we start, and typically live in 2–6 weeks. If we're late, you get 25% back.

Projects start at $4,997. For anything smaller, the free ROI calculator and blog are a better fit.

Shipping production Laravel systems since 2022

Built for clinics, lenders, colleges, agri-traders and dozens of retailers

Every build ships with an admin panel, tests and your own repo

Sound familiar?

You already know which job a machine should be doing.

Someone on your team spends hours a day on it: re-typing invoices into the CRM, calling back leads who went cold, answering the same five questions on WhatsApp, copying numbers between three spreadsheets. You've looked at fixes. A freelancer quoted by the hour and couldn't say when it would be done. A no-code tool worked until it needed your real data. An agency wanted a $20,000 discovery phase.

You don't need a strategy. You need one system, built properly and running by next month.

Four fixed-price builds

Pick the one that pays for itself first.

AI Agent & Automation Build · $7,500 · typically 3–4 weeks

An agent that runs one workflow end to end. It reads the email, PDF or form, extracts the data, updates your CRM or database, drafts the reply and asks a human before anything risky. Up to 2 integrations.

Best for: ops teams buried in manual work.

Scope my workflow →

Voice Agent Build · $7,500 · typically 3–4 weeks

An AI caller that answers or rings leads, qualifies them, books the meeting and logs everything in your CRM. Built on the voice stack we developed for our own Voice Agent product.

Best for: sales and front-desk teams missing calls.

Scope my voice agent →

AI Feature Sprint · $4,997 · 2 weeks

One AI feature inside the app you already run, such as a support copilot, document classifier, lead scoring or smart search. Shipped behind a feature flag with tests.

Best for: SaaS teams whose AI prototype never shipped.

See the Sprint →

Custom App or SaaS MVP · $9,997 · typically 4–6 weeks

A web app, internal tool or SaaS MVP with logins, roles, an admin panel, payments and one core workflow (AI optional). Deployed to your cloud account.

Best for: founders with a pilot customer, demo day or spreadsheet that's outgrown itself.

Bigger than one build? We split it into a series of fixed builds after a $99 Blueprint, so you never sign a blank cheque.

Real repos, real clients

Systems we've built and still maintain.

Lending-tech platform, India (2026)

Bank-statement analysis for loan decisions. It parses statements from 7 major Indian banks, uses Claude to flag cash-flow patterns and bounces, scores risk and exports PDF credit reports. Borrowers upload documents through WhatsApp and Telegram bots.

Laravel · React · Python · Claude

Agri-trading business (2025)

Replaced paper registers for maize procurement with farmer records, weighments, payments, penalties, a payment-due dashboard and exports. First commit to final export feature took about two weeks.

Laravel · Filament

Clinic-management SaaS (2023–25)

Appointments, patient records, treatment plans, prescriptions, invoicing, reminders and subscriptions for multi-doctor practices, plus Flutter apps for doctors and patients. More than 700 merged pull requests.

Laravel · Vue · Flutter · Razorpay

Fireworks retailers, Tamil Nadu (2023–now)

Online ordering, price lists, packing and dispatch, and payment confirmation for dozens of retailers who take most of their year's orders in the weeks before Diwali. One retailer's savings scheme now sends WhatsApp payment reminders and overdue alerts automatically.

Laravel · Filament · WhatsApp Business API

No black box

From first call to production in four steps.

Scope (30 min). One call. We pick one workflow and write down what "done" means. Prefer it in writing? Get the $99 Blueprint.
Fixed quote (within 48 hours). One page: scope, acceptance criteria, price, start date, launch date. No hourly billing, no change orders.
Build (typically 2–6 weeks). Async updates every working day, code in your repo from day one, a staging link to click through, and one or two live calls a week in your time zone.
Launch and hand over. Deployed to your cloud, with documentation and a handover call. Bugs in our code are fixed free for 12 months.

Where the risk sits

If we miss, we pay.

Late = 25% back. The launch date goes in the quote.
Doesn't do what we agreed in writing = full refund. We judge it against the acceptance criteria you signed, not a vibe.
12-month warranty. Bugs in code we wrote are fixed free.
You own everything. Your repo, your cloud account, no licence fees, no lock-in.

Boring, maintainable technology on purpose.

We build in Laravel (PHP 8.2+) with Filament admin panels and React or Vue front ends. Mobile apps are Flutter. We use Python where the AI or voice work needs it. We integrate OpenAI and Claude, Stripe and Razorpay, Plivo telephony, WhatsApp Business, Telegram, Zoho, HubSpot, Salesforce and GoHighLevel. Any competent PHP developer can pick up the code after us.

A good fit if…

You can name the job you want off your team's plate
You have $5,000–$10,000 for the first build and can decide without a procurement cycle
You want it running in weeks, and you want to own the code

Probably not a fit if…

The budget is under $5,000 or you need hourly help
You want a 6-month platform rebuild before anything ships
You need a team to sit in your office (we're remote, India-based, and overlap with US, UK and EU hours)
