Mentor

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.

❗Your team is using AI—but it’s fragmented, unmanaged, and underutilized.❗

Why? Because rolling out AI across your company isn’t just about access—it’s about governance, visibility, and real ROI.

❌ Giving ChatGPT access to a few employees ≠ AI adoption
❌ Shadow AI tools = security and compliance risks
❌ No prompt standardization = inconsistent outcomes
❌ No usage analytics = no learning or optimization

That’s why we built AICamp.

✅ One secure platform to roll out AI to your entire organization
✅ Centralized access to GPT-4, Claude, Gemini & more
✅ Custom AI Assistants, Prompt Library, Usage Analytics — all in one place
✅ Built-in security, governance, and team controls

See how AICamp helps teams adopt AI with structure and speed.
