A few days ago RexiO went live on Product Hunt. What most people saw was a clean launch page and a working product. What they didn't see is where this actually started.
I'm Sijan, the solo founder behind RexiO. I didn't come from a tech family, a CS degree, or any kind of funding. My first real "internet" experience was on a Nokia button phone I could barely afford to put credit on I didn't even understand what the word meant at the time.
Years later, my first paid coding job was a website I built with 20 of mobile balance and zero real knowledge of what I was doing. RexiO itself started as an accident I was building an unrelated social app, added a small AI chatbot just to answer support questions, and that chatbot slowly became more interesting to me than the actual product. I eventually scrapped the whole thing to chase it.
Since then it's been a solo build: writing my own orchestration layer, an intent classifier, 30+ tools, model routing across providers, and fine-tuning our own Bangla-first models on borrowed Colab GPUs plus a full frontend rewrite along the way, more 12-hour bug hunts than I can count, and a relationship ending in the middle of it that honestly redirected the whole direction of my life.
RexiO is Bangladesh's own AI, built by SpritEX. Chat naturally in Bangla or English, get instant answers, generate code, search the web in real time, and get help from an AI that learns who you are every day.
