MISSED CALL LOGGED · 2:14 PM · RESPONSE DISPATCHED

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.

That's a $300–1,200 job, captured automatically — with nobody picking up the phone.
How it works

The whole system, in five steps.

01

Call goes unanswered

You're on a job, driving, or your hands are full — the phone rings out.

02

Instant text-back

The customer gets a reply within seconds, so they don't hang up and dial someone else.

03

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.

04

Job lands in your hands

You get a ready-to-call lead, sitting in your phone, ready to close.

05

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.

Who's behind this

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
Proof

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.

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.

Common questions

Before you call us, you probably want to know this.

Getting started
I've never used anything like this — is it hard to set up?
+
No — you don't set up anything. We configure it on your existing number personally, and walk you through exactly what changed. If you can answer a text message, you already know everything you need to run this.
Speed
How fast will this actually be live for me?
+
Same day, in most cases. Once you send us your business name and number, we set up the forwarding on our end and confirm it's working before we tell you it's live.
Your number
Do I need a new phone number for this to work?
+
No. It runs on the number you already give customers. We set up call forwarding behind the scenes — your number, your business card, your Google listing all stay exactly the same.
Billing
What happens after the 30 free days?
+
It becomes $200/month. No card is needed to start the trial, so nothing gets charged automatically — we'll check in with you before day 30 to see if you want to continue, and you can cancel anytime after that with no questions asked.
Privacy
Is my customers' information safe?
+
Yes. Conversations are only used to build the job ticket handed to you — names, numbers, and job details aren't sold or shared with anyone else.
Already have help
I already have someone answering calls — why would I need this?
+
This covers you the moments they can't — after hours, during lunch, or when a call comes in while they're already on another line. It's a backup, not a replacement, at a fraction of the cost of adding more coverage.
Final step

Want this running on your own number?

Send your business name, phone number, and email, and we'll walk you through the demo built specifically for you — no cost to look, no obligation after.
