We're building Kolkata's first AI-native real estate advisory
Thirteen years advising home-buyers and investors in Kolkata — now rebuilt around a simple conviction: choosing a home worth a crore or more deserves better than a glossy brochure and a pushy sales call. So we evaluate every project with the rigour an institutional investor would apply, and hand you the analysis for free.
Where we started
Sidus Realty was founded in Kolkata in 2013 by Ashish and Aditya Goyal. From the beginning the model was deliberately different from a traditional broker: we work as an authorised channel partner for the city's leading developers, which means we represent their projects directly — and you pay us nothing. Our brokerage is paid by the developer, so our advice is never bent by what a buyer’s commission would be.
For over a decade we’ve specialised in Kolkata’s premium and investment-grade residential segment — homes priced upwards of ₹1 crore — across corridors like New Town, Rajarhat, Tollygunge, EM Bypass, Joka, New Alipore, Ballygunge and Alipore. We know these neighbourhoods street by street — and we only put our name behind RERA-verified developments.
Why we rebuilt the firm around AI
Here’s the honest problem with buying property in Kolkata. At any given time there are over 300 active residential projects, and nearly all of them look excellent on a brochure. In practice only a handful will hand over on time, appreciate in value, and hold up structurally over the 20-year horizon that actually matters for a home. Most brokers are paid to push whichever inventory pays them the most — which is exactly the wrong incentive when you’re spending crores.
We decided to be the opposite of that. Instead of louder marketing, we built an evaluation system.
That’s the Sidus Score: a single number out of 100, backed by private sub-scores our team reviews and can override. On top of it sits our Investment Memo Generator — tell it which project you’re weighing, why you’re buying, and your budget, and it writes you a personalised, investor-grade memo in about thirty seconds, complete with an all-in cost breakdown at current West Bengal rates, a risk matrix, and comparable projects.
This is what “AI-native” means for us — not a chatbot bolted onto a broker’s website, but real analysis you can print, forward to your spouse or accountant, and act on. The technology does the filtering; our 13 years on the ground do the judgement.
What we’ve built for buyers
Free to use, no sign-up wall except where noted. Every one of them exists to help you decide, not to sell you.
Our four-dimension evaluation framework, scored out of 100. It’s how we tell you which projects deserve a serious look — and which ones we won’t list at all.

The AI-native real estate company
To build the most trusted real estate advisory in India — one where every recommendation is backed by transparent evaluation, not sales incentives, and where technology makes honest advice scalable.

Integrity, in the incentives
Integrity in every conversation, complete transparency on price and paperwork, and a customer-first model built into how we’re paid — not just how we talk. That’s how we’ve earned trust in Kolkata for years.
The people behind Sidus
Sidus is founder-led. When you deal with us, the philosophy that runs the firm is the same one that shapes every recommendation you get — honest evaluation over hard selling.
Ashish founded Sidus Realty in 2013 with a contrarian bet: that a real estate advisory could win by being genuinely honest rather than aggressively promotional. Over thirteen years he’s built deep, first-hand knowledge of Kolkata’s micro-markets — how each corridor has actually priced over time, which developers deliver, and where value really sits versus where it’s only marketed. Today he leads the firm’s strategy and its AI-native product direction, from the Sidus Score to the investment memo engine, translating that ground-level expertise into tools any buyer can use.
Aditya co-founded Sidus and drives the firm’s developer relationships and inventory access across Kolkata. Those direct partnerships are what let Sidus offer first-hand pricing, real availability and genuine offers at zero brokerage to the buyer — and what keep the shortlist current across the city’s leading builders. He works closely with developers and buyers alike to make sure what reaches you is accurate, RERA-verified, and worth your time.
