Ongoing Tech Help Every Month, Without Hiring a Full Team
TENSIX retainers give you a set amount of engineering work, server care and technical advice every month, delivered directly by founder Hemal Shah with the help of AI tools. Plans start at ₹39,999 a month, and the Growth Engine plan can be paused or cancelled at the end of any 30-day cycle.
What is a Fractional CTO for growing businesses?
A Fractional CTO is an experienced executive software architect who provides part-time, high-impact technical leadership, systems architecture, and engineering oversight without the ₹40L+ annual overhead of a full-time executive. At TENSIX, fractional CTO retainers pair hands-on code commits, server infrastructure hardening, and vendor technical vetting with flexible 30-day cancellation terms.

Common questions
What is a fractional CTO?
A fractional CTO is a senior technology leader who works with you part-time. You get help with technical decisions, planning and hiring without paying a full-time salary.
How is TENSIX structured?
TENSIX is run by one person, founder Hemal Shah. He uses AI coding and automation tools to work faster and reviews all the work himself, so you always deal with him directly.
Can I cancel?
The Growth Engine Retainer can be paused, changed or cancelled at the end of any 30-day cycle. The other plans run on a rolling monthly agreement, with notice terms agreed in writing before you start.
What counts as one engineering sprint?
A sprint is a focused block of work with a clear goal agreed at the start of the month, such as one new feature, one automation or one landing page.
Do you also do one-off code audits?
Yes. Hemal can review your code, database or cloud set-up and give you a written list of problems and fixes covering speed, security and cost. Contact Hemal for a quote.
Who owns the work done under a retainer?
You do. All code goes into your own GitHub account and runs on your own cloud accounts.
