On 4th July 2005 at 5:52 UTC, my life changed

This day taught me how a 15-year-old child sitting in a small town of Ahmedabad, India, through a connection and by taking an initiative can be part of something bigger, that takes one out of the world. 

NASA launched its bold mission to impact the comet and few people from earth got a chance to be part of that mission and I was one of them. The Deep Impact spacecraft travelled 429 million km (267 million mi) in 174 days to reach comet Tempel 1 at a cruising speed of 28.6 km/s (103,000 km/h; 64,000 mph).

This incident changed my perspective on how small things can lead to a big impact you can never think of.

In the following years, I excelled at education, worked with cross-functional teams from product, technology, operations, marketing,  sales, customer success to drive and to lead companies on collaborative, strategic initiatives leading to an impact of 300M$+

Over the last decade, I have worked with early stage startups, SMBs, Enterprises and Government Institutions and worked on cross-functional projects to deliver impact.

Now, I work with SaaS companies to increase their onboarding & retention through product growth and  generating a product strategy that makes the user comes back and get their job done by taking a unique collaborative cross-functional inter-department approach with sales, marketing, product and tech teams.

Helping non-tech businesses build software products in 8-12 weeks | DM me your app ideas | Owner - Ionio |

Hi, I'm Rohan! I run Ionio — a strategic AI consultancy for Retail & Ecom SaaS. We help mid-market platforms ($5M-100M ARR) build AI features that reduce churn, justify premium pricing, and turn their product into something merchants can't live without.

Over the past 5 years, we built 40+ products and helped founders go from zero to seven figures multiple times. Same playbook, over and over: take an idea, ship it fast, make it work, scale it.

After doing that tens of times, we wanted to take everything we learned and bring that energy to companies at the next stage. That's how we ended up focused on mid-market Retail & Ecom SaaS.

I'm genuinely passionate about this space. Generative AI lets us do something that was never possible before: personalize every single customer interaction. Not segments. Not cohorts. Actual one-on-one conversations at scale. Retail and ecom is where that has the biggest impact.

I've been working in AI since 2016 — back when that meant computer vision, not ChatGPT. Smart cameras, facial recognition, number plate recognition. That foundation matters when you're building production systems that actually need to work.

Previously: From 18 to 20, Sr. Software Engineer at SmartCow (Deep Tech AI company in Malta). At 17, Python work for a Mumbai startup, who are YET to pay me. At 15, building websites and apps for family friends in Java. It's been over a decade.

I started Ionio as a college junior, from my parent's bedroom, while hiring someone to do my assignments & a chauffeur to take me to college. Now it's a little less grunge than that.

In another life: rapper, musician, and cinematographer. Now I just build AI for retail... :(

What our clients say:

"Working with Ionio felt like having an extension of my own team — professionals who genuinely cared about delivering results, not just collecting a check."
— Stefan Georgi, Founder, 9-figure ecom founder

"Fastest I've ever launched a polished product. From wireframes to +1000 paying users in <8 weeks."
— Brad Milne, CTO, SupplierHQ

"Ionio has the character to navigate challenges and the technical depth to turn our 'AI-first' vision into reality."
— Sallyann Della Casa, CEO, Gleac

Read 35+ case studies on our site.

I post about: AI strategy for retail, technical deep dives, and behind-the-scenes of building Ionio.

If you're leading product, engineering, or strategy at a Retail & Ecom SaaS company, or a founder in any space — DM me, I always reply. If you're in Mumbai, I'll buy you a coffee.
