They called. You missed it.
Someone else got paid.
Sindero texts them back in seconds, asks what they need, and hands you a ready-to-call lead — before they dial the next name on Google.
The whole system, in five steps.
Call goes unanswered
You're on a job, driving, or your hands are full — the phone rings out.
Instant text-back
The customer gets a reply within seconds, so they don't hang up and dial someone else.
Details get gathered
A short back-and-forth learns their name, the issue, location, and how urgent it is — so real emergencies stand out from routine calls.
Job lands in your hands
You get a ready-to-call lead, sitting in your phone, ready to close.
If it sits too long, we remind you
Haven't called back yet? You get a nudge — so a real lead doesn't quietly go cold.
Built by two people, not a company.
We're Yassin and Bakr. We built Sindero after hearing the same story too many times — a plumber on a job, a customer who called, and a job that went to whoever picked up next. So we fixed it, tested it on ourselves first, and now we set it up personally, by hand, for every business we bring on. No call center, no support queue — just two people who'd rather prove this works than promise it does.
YASSIN & BAKR
We tested this before we ever showed it to a business.
We built the AI, the missed-call detection, and the text-back flow — then ran it against real scenarios ourselves before putting it in front of a single plumber. The demo above isn't a mockup or a video. It's the same system, live, responding to whatever you type.
What's new isn't whether it works — it's that we set it up personally, by hand, instead of a self-serve signup queue.
After 30 days, it costs less than one lost job a month.

No new habits to learn
Nothing to log into, nothing to check. It runs on its own, quietly, in the background.
You stay in control
Every lead lands as a text on your phone — you call, you close, on your terms.
Nothing sits forgotten
If a lead goes unanswered too long, we nudge you — so it doesn't quietly turn into a lost job.
