Usually, it's new to the team
Nobody in the room has built it before, so no one can say yet whether it will work on real data, or run fast enough on real hardware.
A small senior team of tech experts, led by Sachin Garg, CTO
We help you find out if your hard problem can be built, then lead the research and build.
We guide your team through a small prototype on your own data, before the budget moves.

27+ Years building software
30+ Products delivered
21+ Years leading teams
- Rawzor started in 2008 with image compression research. Since then we've built the signal processing for a blood-glucose monitor that plugs into a phone's audio jack.
- We started with AI/ML in 2013, when we trained computer vision ML models to detect and track fish species in open waters, and implemented image compression algorithms that ran on GPUs in 94.7% less time.
Why the hard part goes first
The part nobody is sure about gets built first.
It's tested on the hardware it has to run on, and you see the measurements before anyone commits to the full build.
We don't rent you developers. Anyone we help you find joins your team, not ours.
Why the test data matters
A new set of test images, in 2007
The standard test images for compression research were too small, too old, and only 8-bit precision. In 2007, Sachin put together a new high-resolution, high-precision set, each image picked to stress the algorithms in a different way. We test your prototype on the most appropriate data.
What we usually find
The right intent, not yet the experience.
A hard problem needs people who have solved problems like it before.
02 · What we do first
Who has solved it before
Before anything gets built, we look for people and tools that have already solved your exact problem. Then the prototype only has to answer what's still unknown.
03 · If it's worth building
The full build, with your team
We lead the work with your team and the specialists it needs, and make sure it ships.
Some of the work
Hard problems, built and measured.

An AI project at a crawl, shipped once the right specialists joined
AI · VoIP, New York
18.8× · Deep tech · Image compression
Compressing an 8 megapixel image with a proprietary algorithm took 3 to 4 minutes on iOS and Android. We moved the same algorithm onto the GPU, and it took around 10 seconds, 94.7% less time. We used OpenGL shaders instead of CUDA or OpenCL, so it stayed portable across desktop and mobile.
100 at 30 FPS · Deep tech · Computer vision
In 2013, we developed and trained computer vision machine learning models for detecting and tracking fish species in open waters. Keeping detection and tracking separate made it far more efficient: up to 100 objects at 30 FPS on a 3.1 GHz 4-core Intel i7, using OpenCV.
9 → 2 months · AI · VoIP, New York
A New York based VoIP company had spent nine months on an AI project that was moving at a crawl: self-hosting ASR models and LLMs for transcribing and summarizing calls, to keep costs down at scale. We brought in the right specialists, and it shipped in two months. We also drove the GPU batch-processing optimizations.
How we work
From stuck to self-running.
Your team takes on a little more each month, until it runs without us.
01 Weeks 1–3
Get clear
Where things really stand, including what leadership doesn't hear.
02 Early on
Make it visible
Honest updates, and a working build you can try every week.
03 Along the way
Build it up
Simpler architecture, vendors held to their word, gaps filled.
04 When you're ready
Hand off
Nothing depends on one person, including us.
01 · Weeks 1–3 What we look at first
- What you're trying to achieve, and where things really stand.
- The quality of the work so far. It can go either way: sometimes it's 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.
- The gap between what we hear from leadership and what we hear from the people doing the work. That gap usually tells us the most.
02 · Early on 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 we see start with updates that skip the details.
03 · Along the way Stronger, step by step
A simpler architecture, vendors held to what they promised, and specialists added where the team has gaps. Your people take on a little more each month.
04 · When you're ready A team that doesn't need us
Knowledge moves to your team, and we help you hire anyone who's missing. By then, no part of your product should depend on one person, including us.
Ways to start
Everything starts with one 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 Sachin on your real problem
- Real answers and clear next steps on the calls themselves
- Up to two follow-ups, with you or your team
- Not worth it? One click, full refund
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 · After the call
A fixed-scope review
$3.5–6K Fixed price, 2–3 weeks
A small prototype of the part nobody is sure about, built by your team on your own data with our guidance, and measured.
- Whether it works on your data, and runs fast enough on your hardware
- Whether your timeline and budget estimates are realistic
- Solutions to the problems we find, worked out together with you and your team
03 · After the call
Working together
$8–12K a month or a fixed-scope project
If it can be built, our senior team leads the build with your people, through to a planned hand-off.
- Sachin sets direction and checks the work
- Milestones tied to features your users can actually use
- A planned hand-off to your own team

Bring whoever on your team knows the problem best.
Why is the first call paid?
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.
What if it can't be built?
Then you hear it early, with the measurements that show why, while changing course is still cheap.
Who writes the code?
We provide senior product guidance to fix your prototypes. After that, your developers, or specialists we help you hire who have solved your exact problems before. We lead the work and make sure it ships. We don't rent you developers.
Does Sachin work on it himself?
Sometimes, for a tricky performance problem or a code review. Mostly he makes sure the right people are writing it, and that what they build is what you actually need.
