01 · Underneath
Usually, the system still works
What's missing is the confidence to change it: what it really does lives in one person's head, or left with the vendor who built it, and there are few tests to catch a mistake.
A small senior team of tech experts, led by Sachin Garg, CTO
We help you make your old system safe to change again.
We start with the system you have, and with whoever on your team knows it best.

Why we build on what works
Rewriting it from scratch is rarely the answer.
When every deploy feels risky, we make changes in small, safe steps until shipping is routine again. We lead the work with your team, and make sure it ships.
We don't rent you developers. Anyone we help you find joins your team, not ours.
A New York based VoIP company's mobile apps
Native iOS and Android apps
One hybrid app, sharing the web app's code
The native iOS and Android apps were brittle and unstable. We planned and led the move to one hybrid app that shared most of its code with their web app, which was already stable. The app became much more stable, customers were happier, and it cost less to maintain, with half the team it needed before.
What we usually find
Every change feels risky, so people stop making them.
We find out why, and fix it with the people you already have.
02 · Make it safe to change first
Before anything changes
Automated tests around the parts your business can't do without, so a mistake shows up before your users see it. Then each change is small enough to check properly, and easy to undo.
03 · If a part really needs replacing
Old and new, side by side
The new piece runs alongside the old, and the old stays until the new one has proven itself with real users.
Some of the work
Stalled work, moving again.

One telehealth platform, first version to retirement, used by Mayo Clinic and Boston Children's
Telehealth · Boston and Denmark

An AI project at a crawl, shipped once the right specialists joined
AI · VoIP, New York
8 years · Telehealth · Boston and Denmark
We led a client's telehealth platform from its first version to retirement. Through the Covid19 waves, Partners Healthcare, Boston Children's, Mayo Clinic, and municipal healthcare providers across Denmark used it. Along the way, the team went from 13 people in three countries to a remote team of four, and delivery got twice as fast.
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 close look at the system, what depends on it, and the people who know it best, with solutions worked out alongside your team.
- The code, and how changes get tested and deployed today
- Which parts carry the most risk, and what to change first
- 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
Our senior team works the plan with your people, through to a planned hand-off.
- Sachin sets direction and checks the work
- Delivery led week to week, alongside your team
- A planned hand-off to your own team

Bring whoever on your team knows the system 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 really needs a rewrite?
Then we'll say so plainly, and tell you which part. Sometimes one piece really is cheaper to rebuild than to fix. It's rarely the whole system.
What if only one person knows it?
Then they stay at the center of the work, and what they know gets shared as we go. If they've already left, it takes longer, but it can be done.
Can AI help with an old system?
Yes, and we use it. For a New York based VoIP company, we used AI to help migrate their old front ends. With or without AI, we make changes in small, safe steps.
Do you take commissions from vendors?
No. We take no reseller fees or commissions from any vendor, so we're truly on your side, with only your best interest in mind.
