Sachin Garg, fractional CTO

If you're not sure it can be built, or whether to build or buy, I can help you find out, then lead the build.

I've been building software for 27 years, from GPU speedups to computer vision and audio, long before any of it was called AI. So I can usually tell quickly whether something can be built, and what it will really cost.

What I usually find

Usually, it's new to the team

The team often has the right intent, but not yet the experience for the decision in front of it. Nobody in the room has built this exact thing before, and the best person for a hard problem is someone who has already solved it.

First, a small prototype

If the answer isn't clear on the call, we guide your team to build a small prototype on your own data, and help you read what it shows, before the budget moves. Real data is messier than the demo's.

Bought the CRM, built the portal

At a revived heritage travel brand, we moved a 40-person sales team onto a new CRM, bought off the shelf. And an in-house portal replaced several paid travel-booking tools in about three months, built around how their team actually works. It cut both the licensing and the running costs.

A note from me

The standard test images for compression research were too small, too old, and only 8-bit precision. In 2007, I put together a new high-resolution, high-precision set, each image picked to stress the algorithms in a different way. I test your prototype on the most appropriate data.

Some of the work

Deep tech · Image compression 18.8× faster image compression on the GPU
Deep tech · Computer vision 100 at 30 FPS objects detected and tracked in real time
AI · VoIP, New York 9 → 2 months: an AI project at a crawl, shipped

Clients stay unnamed here. I'm happy to walk you through any of these on a call.

How I work

Weeks 1–3 · Get clear

What I look at first

What you're trying to achieve, and where things really stand. The quality of the work so far, and how the ground reality compares with how it feels to you. That can go either way: sometimes the work is worse than it looks, and sometimes it's much better than it feels, simply because it isn't finished yet. The skills the job needs against the skills on the team. Whether your timeline and budget estimates are realistic. And the gap between what I hear from leadership and what I hear from the people doing the work. That gap usually tells me the most.

Early on · Make it visible

Progress everyone can see

Status updates that say what's really done, in enough detail to act on, and a working build you can try every week. A lot of the misunderstandings I see start with updates that skip the details.

As gaps show up · The right people

People who've solved it before

I look for people and tools that have already solved the exact problem you're struggling with, not just a good developer, a good marketing team, or a good CRM. A job post that says “great machine learning engineer” vs “a machine learning engineer who has worked on audio models, and plays a musical instrument” can turn a 3-month project into a 3-week sprint.

When you're ready · Hand off

A team that doesn't need me

Knowledge moves to your team, and if you need a full-time CTO, I help you find the right one. By then, no part of your product should depend on one person, including me.

How we'd start

Everything starts with one paid call. By the end of it, we'll both know whether there's more to do, and which of the other two options fits.

01 Start here

A first call

$500
  • 90 minutes with me, working on your actual problem.
  • Real answers and clear next steps on the calls themselves.
  • Up to two follow-ups, with you or the people on your team.
  • If it wasn't worth it, one click refunds the full $500.
Pick a time

The right first step for nearly everyone.

Some teams take the solutions and run with them on their own. That's a perfectly good outcome.

02

A fixed-price review

$3.5–6K

A close look at the question and at what you have so far, over two to three weeks.

  • A small prototype, built and measured on your own data
  • The cost of each option: build or buy, your own servers or an API
  • Solutions to the problems we find, worked out together with you and your team
03

Your fractional CTO

$8–12K a month

A few hours a week on the hard technical calls, and on getting the right people to build it. The monthly range depends on how much of my time you need.

  • Architecture, hiring, and vendor calls
  • Finding specialists who have already solved your exact problem
  • A planned hand-off to your own team

Bootstrapped and pre-revenue? Book a 40-minute Founder Call for $200. It doesn't include follow-up calls, and the same one-click refund applies.

Fair questions

Because it's working time on your problem, and you get real answers on the call itself. It also covers up to two follow-ups, including calls with people on your team if needed.

Sometimes, for a tricky performance problem or a code review. Mostly I make sure the right people are writing it, and that what they build is what you actually need.

Then I'll tell you plainly, and show you why, before the money moves.

A sample of your real data, whatever you've built or tried so far, and time with the people who know the problem best.

No. I take no reseller fees or commissions from any vendor, so I'm truly on your side, with only your best interest in mind.
