Web Development Company in Mumbai.
Plazmasoft builds production-grade web apps, mobile apps, and AI-powered products for startups and growing businesses. Office in Ghansoli, Navi Mumbai, working with clients across Mumbai and globally.
Local, But Not Only Local
A dev studio in Navi Mumbai, built for global clients
Plazmasoft has an office in Ghansoli, Navi Mumbai, with our head office in Noida. Having a presence in Navi Mumbai means Mumbai, Navi Mumbai, and Thane-based founders can meet the team building their product in person, not just over a call.
Most of our work still happens remotely. We build for clients across India, the US, the UK, and the UAE, using the same process either way: a written scope document, two-week development sprints with a working demo each time, and direct access to the engineers on your project instead of an account manager relaying updates.
Our stack is Laravel and React for web applications, Flutter for cross-platform mobile apps, and GPT-4, Gemini, or custom LLM pipelines when a product needs AI. We build MVPs, extend existing codebases, and take on full product builds for founders who need software that ships, not a demo.

How We Work
From discovery call to launch
Discovery call
We spend 45 minutes learning what you are building, why, and who uses it. We ask about your timeline, budget, and any constraints. No pitch, just questions.
Scope and spec
We write a detailed scope document covering every screen, API endpoint, and user flow. This becomes the contract. No surprises mid-project.
Design
We design in Figma before writing a line of code. You approve the design. Only then does development start.
Development sprints
We build in two-week sprints with a working demo at the end of each. You can see real progress, not status updates.
QA and launch
We test on real devices, browsers, and screen sizes. We fix every bug before handover. Then we deploy and help you go live.
Post-launch support
Every project includes a 30-day bug fix window after launch. We are also available for ongoing development retainers.

Client Stories
What clients say
"Rajnandan delivered a two-sided marketplace in 4 months that I had been trying to build for a year with another team. He understood the product deeply from the first call and pushed back when my ideas were not practical. The code is clean and the app has been running in production without any major issues."
Pravin Sharma
Founder, Ongofix
"We needed someone who understood trade finance, not just Laravel. Plazmasoft took the time to learn our domain before writing any code. The platform they built handles complex document workflows that would have taken a bigger team months longer to figure out."
Dipesh Shah
CEO, TradeGuardian
"We had 8 weeks and a tight budget. Plazmasoft delivered a complete customer app, driver app, and operations dashboard on time and within budget. The route optimisation alone saved us 30 percent on driver costs. I would hire them again for the next product."

Common Questions
Working with a Mumbai-based studio
Where exactly is Plazmasoft located in Mumbai?
Shop No. 58, Vrindavan Dham, Plot No. 5 to 8, Sector 5, Ghansoli, Navi Mumbai 400701, Maharashtra, India. We also have a head office in Noida.
Is your office in Mumbai or Navi Mumbai?
Our Mumbai office is in Ghansoli, Navi Mumbai. We work with clients across Mumbai, Navi Mumbai, and Thane, in person or remotely.
Do you only work with clients based in Mumbai?
No. Having an office in Navi Mumbai means local founders can meet the team in person, but most of our clients work with us remotely, including startups in the US, UK, and UAE. Video calls and async updates work fine for the vast majority of projects.
Can we meet in person before starting a project?
Yes, if you are in Mumbai, Navi Mumbai, or Thane. We are happy to do an in-person discovery call at our Ghansoli office or at your location before any commitment.
What kind of companies in Mumbai do you typically work with?
Mostly early-stage startups and small to mid-size businesses that need a production web or mobile app, not just a prototype, plus a few established Mumbai-based companies extending or rebuilding an existing product.
How much does a website or web app cost in Mumbai?
A focused MVP web app typically runs INR 2 to 8 lakh depending on scope. A simple business or marketing website is cheaper. We quote a fixed price off a written scope document, not a ballpark number on a call.
How long does a typical project take?
A focused MVP takes 6 to 8 weeks. Larger products with multiple integrations take 3 to 6 months. We scope every project before giving a timeline so the estimate is one we can actually hold to.
What technologies do you build with?
Laravel and React for web applications, Flutter for cross-platform mobile apps, and GPT-4, Gemini, or custom LLM pipelines for AI integrations. We pick the stack based on what the product needs, not what is trendy.
