Hi There

Profile

I am Amit Kumar (X / Twitter). This website is home to my thoughts and writing.

Who I am

I'm a builder at heart, and have been in building mode ever since I first learned to program. It still amazes me how many of the world's problems can be solved by just building great software.

I love reading, technology, psychology, and finance. In my free time, I love watching comedy.

What I'm doing now

I'm the founder of toflow.ai, and a passionate builder of software products. Over the course of my career, I've had the opportunity to build and contribute to amazing products across domains — gaming, mobility, quick commerce, construction tech, and now sales tech.

Experience

  • toflow.ai — Founder. Building an AI-native outbound automation platform for sales teams, helping them automate LinkedIn and email outreach using Claude / ChatGPT.

  • RDash (YC W22) — Founding CTO. Built the team and turned the founder's vision into a SaaS product for design and build firms. Led the technology vertical until my departure, by which point the company had reached $1.5M ARR. Also played a crucial role in setting up the initial sales enablement stack, including inbound, CRM, and outbound.

  • Blinkit — Team Lead. Joined as part of the company's transformation journey from Grofers, a grocery delivery company, into the quick-commerce giant it is today. Built the core of the search infrastructure and the customer experience around cart checkout. Built the Checkout Service, one of Blinkit's core services, powered by FastAPI, async Postgres, and DAGs — it currently powers 3 million orders per day.

  • Mobility (Shuttl & Koko) — Worked at Shuttl, a commuting service for office-goers, and later as Head of Engineering at Koko, an "Uber for rickshaws."

  • Times Internet — Engineer, IC. Spent the first 2 years of my career mostly as a hands-on individual contributor, where I helped build Times Assistant (an AI assistant for Times Internet, India's largest digital company after Meta and Google), and later Brainbaazi, a "Who Wants to Be a Millionaire" style game for Indian audiences.
