Owner · Lahiri & Byrne Consulting · Priyanka Ganguly
That's where the work happens.
Ugly. Overweight. Built something he didn't entirely plan, with people he didn't expect to find, in a direction he didn't predict. Still going. Still surprised.
About
Rahul Lahiri is the Owner of Lahiri & Byrne Consulting Private Limited — a firm he founded in 2023 after the entrepreneurship bug bit him during what he describes as a "perfectly mediocre" 9-to-5. The company found its footing in its first year — no investors, no safety net, and more moments of genuine uncertainty than he'd like to admit. Some of it was hard work. Some of it was good timing. Some of it was pure dumb luck, and he's honest enough to know he can't always tell which was which.
Based out of Howrah, West Bengal, India, he specialises in helping small, early-stage businesses grow — with a particular focus on e-commerce in US domestic markets. He's worked across industries, stumbled into some of them entirely by accident, and found that occasionally the stumbling is where the interesting things are. He doesn't have credentials on a wall. Some clients have come back, which he finds quietly encouraging and tries not to overthink.
When he's not buried in growth strategy or digital marketing, you'll find him reading things nobody asked him to read, thinking about the heat death of the universe, and drinking more tea than is probably advisable. He speaks Bengali, English, and Hindi — and isn't on any social media platform, which he finds suits him just fine and his productivity enormously.
Let's be honest: Rahul is ugly and fat. He knows it. His clients know it. The mirror has known it for years. Nobody is hiring him for his looks. They hire him — when they do — because he shows up, tries hard, and is honest about what isn't working. There have been wins. There have been failures. There have been moments that went well for reasons he still can't fully explain. He'll tell you about all of it — the failures, frankly, taught him considerably more than the wins did.
What We Do
Lahiri & Byrne works with early-stage and growing businesses to do the things that actually move the needle. See client work →
Clean, fast, conversion-focused websites that don't embarrass you in front of customers.
Getting your business in front of the right people — not just any people.
Emails people actually open. Which, in 2025, is genuinely saying something.
Making the behind-the-scenes run smoothly so your team isn't firefighting at 4pm every Friday.
A clear plan for where you're going and how to get there — without the 80-slide deck nobody reads.
Deep expertise in US domestic e-commerce. If you're selling online in America, this is the lane.
Fun Facts
Ugly. Fat. Profitable. Not necessarily in that order, but all equally true. His clients care about exactly one of those three things.
Takes genuine joy in simple things — a strong cup of tea, a quiet evening, an interesting conversation about the nature of the universe. He does not need much. He cares deeply about doing good work — the wins, the losses, and especially what the losses teach you.
Would not survive a photo shoot. Has not survived every business challenge either — but he's faced them all, learned from the ones that went wrong, and shown up again anyway.
Grossly overweight by conventional measures. Working hard, making mistakes, and learning from them by every other. Still going. That counts for something.
Has strong opinions on cosmology, philosophy, literature, and science. His clients, for reasons that remain unclear to him, keep coming back.
Has strong opinions about tea, the heat death of the universe, and why most business decks are written for the person who made them, not the person reading them. He will share all three — unprompted, at length — and somehow make it feel like time well spent.
Has exactly one wife — Priyanka Ganguly — which, by all accounts, is already more responsibility than most people can handle. He considers this, without question, his best decision. Whether the feeling is mutual is a separate conversation.
Has no Instagram, no Twitter/X, no LinkedIn, no TikTok, and no Facebook. Is therefore, by current societal standards, either a recluse, a luddite, or a deeply suspicious individual. He is none of these. He simply looked at what social media was asking for in return — attention, time, a quietly eroding sense of self-worth — and declined the terms. His clients reach him by email. He replies promptly. The algorithm is not involved.
Is the proud father of two sons: a Labrador Retriever named Tonic Poochie Lahiri, the elder son (born 2021, extremely fluffy, answers to nobody, zero business sense), and Srijon Sankar Lahiri, the younger son (born 2025, human, already showing signs of chaos). Together they have formed an unspoken coalition dedicated entirely to making Rahul question every life decision he has ever made.
Career
No corporate ladder. No conventional career path. Just a sequence of decisions — some good, some embarrassingly wrong — and a stubborn refusal to stop learning from both.
Quit a perfectly mediocre job, bet entirely on himself, and started a consulting firm with no investors, no loans, and no safety net. Most people thought this was a terrible idea.
The company turned profitable in its first year of operation. No external funding. No investors. He still isn't entirely sure how.
Built hands-on expertise in US domestic e-commerce markets — not through coursework or certifications, but through doing it, repeatedly, for real clients with real money at stake.
Across industries, across geographies — some clients grew significantly, some engagements didn't go as planned. Every single one taught him something. That accumulation — good and bad — is what he brings to the table. See the work →
