The problem

Money isn't lost at the sale. It's lost before it.

Every operation has two silent leaks: customers who walk away for lack of a reply, and the hours your team burns on repetitive tasks. Neither shows up in a report — and both cost money every day.

1

Nobody answers in time

The customer writes at 9 p.m., on a Sunday, or during rush hour. By the time someone replies, they already bought elsewhere.

2

Follow-up depends on memory

"Let me think about it" is a sale nobody touches again. Without a system, follow-up lives in a busy person's head.

3

Repetitive work drains the team

Data entry, generating documents, answering the same question 40 times a day. Hours of valuable people spent on tasks a system does better.

The process

How we work

No black boxes. This is exactly what happens from first contact to the point where your system keeps improving month after month.

Step 1 · Audit

Diagnostic & audit

Investment
Free

The starting point. Before proposing any technology, we measure your operation — because you can't improve what hasn't been measured. For larger operations, we offer an in-depth written audit as a standalone service.

1

20-minute call

We learn how your requests come in, who handles them, and which processes consume most of your team's time.

2

Operations map

We document channels, volumes, schedules, and the exact points where customers or working hours get lost.

3

Δ calculation

We quantify the leak in money: what it costs per month when things go unanswered, unfollowed or done by hand.

4

Prioritized plan

You receive the three actions that recover the most results, in order. The plan is yours, whatever you decide.

Step 2 · Implementation

Implementation: agents & automations

One-time fee
Quoted in your audit

We build your complete system: the AI agents that talk with your customers and the automations that run your internal processes. Everything integrated with the tools you already use — and nothing goes live without your approval.

1

System design

We define which agents and which automations your operation needs, in what order, and what they integrate with.

2

Build & training

We train each agent on your real information: pricing, policies, tone of voice and human-escalation rules.

3

Integration & testing

We connect your calendar, CRM and customer channels. You test the system and we tune it until you approve.

4

Go live

We activate in phases, monitor closely during the first week and fine-tune with real conversations.

Step 3 · Growth Partner

Growth Partner

The goal isn't to install a system. It's to grow with you.

Implementation solves today's problem. The partnership solves tomorrow's.

Every month we review your operation's numbers, find the next bottleneck and fix it. Your system doesn't stay the same — it improves as the business does.

We're not a vendor you call when something breaks. We're the person who tells you what to fix before it does.

01Monthly metrics review and identification of the next bottleneck
02Ongoing adjustments and improvements at no extra development cost
03New automations as the business grows
04Direct access — no support tickets, no middlemen
Let's talk about the partnership
Solutions

Systems that work while you sleep.

Two fronts, one goal: conversational agents serve your customers on the outside, and automations run your processes on the inside. We choose the ones your operation needs — starting with the one that recovers the most results.

A Conversational agents — the face to your customers

Automated response across every channel

Replies in seconds by text, direct message, web chat or email, handles the common questions and hands off to a person when it matters.

Voice agent

Answers the phone with a natural voice, books the appointment on your calendar and never misses a call.

Booking & reminders

Offers real time slots, confirms, reschedules and reminds. Fewer no-shows, fewer back-and-forth calls.

Follow-up & reactivation

Follows up on every "let me think about it" and re-engages the people who quoted and never came back.

Lead qualification

Separates the curious from the buyer before your team invests an hour. The good ones reach your closer ready.

After-hours coverage

Nights, Sundays and holidays covered. Most lost requests arrive when nobody is working.

B Operations automations — the engine inside

Documents & quotes

Generates, organizes and sends documents, quotes and invoices with no manual typing and no copy-paste errors.

Data & CRM in sync

Every conversation, appointment and sale gets logged where it belongs — no copy-pasting between systems.

Reports & internal alerts

Your team gets the right information at the right time: daily summaries, tasks, deadlines and alerts.

Industries

Any business with customers who expect an answer.

Every system is trained for the specific operation of your industry. These already have proven templates — and if yours isn't listed, we build it from scratch.

About

Why Delta Y exists.

The story behind the name, and the reason we work the way we work.

Delta Y wasn't born from a trend. It was born from seeing the problem up close.

Working alongside professionals from different fields — accountants, lawyers, operations teams — Delta Y's founder watched the same pattern repeat itself: talented people investing hours in repetitive tasks, information scattered across systems that don't talk to each other, customers waiting for answers that arrive late, and money leaking through processes nobody has time to fix.

And that's where the opportunity was: artificial intelligence now allows a business to achieve better results without growing its structure — with the team focused on what creates value, while systems take care of the repetitive work. More efficiency, better metrics, an operation that's genuinely organized.

That's why Delta Y exists: to install those systems in businesses of any industry, anywhere in the world — so that change isn't a promise, but a number measured every month.

Δy

Δ (delta) is the mathematical symbol for change. Y is the output variable — and also the fork: the point where one path splits in two. Δy = the change in your result. It's our name, our promise, and the only metric we accept to be judged by.

— Mission

No business should lose a customer for lack of a response, or an hour of its team's time on a task a system can do.

— Vision

To be the reference AI growth partner globally: intelligent systems working inside every operation that decides to grow.

— Principles

We measure everything — the Δ is the metric. We speak plainly: if AI isn't right for you yet, we say so. And no lock-in: you stay because it works.

FAQ

What everyone asks before saying yes.

Straight answers, no fine print. If your question isn't here, the assistant in the corner or the audit will solve it.

How is this different from a cheap chatbot?

A chatbot answers questions. An AI agent does things: checks your calendar, books the appointment, updates your CRM, sends the reminder and escalates to a human when the conversation needs it. And we train it on your pricing, your policies and your tone.

Do you only serve customers, or automate internal processes too?

Both. Besides the agents that talk with your customers, we automate internal operations: document and quote generation, data entry, CRM synchronization, reports and alerts. If a task is repetitive and follows rules, it can almost certainly be automated.

How much does it cost?

It depends on scope — that's why the audit is free: we don't quote without knowing what you need. Implementation is a one-time fee based on the agents, automations and integrations, and the partnership is a flat monthly fee with no lock-in. You leave the audit with the exact figure.

How long until it's running?

7 to 14 days for a standard system. Cases with complex integrations or multiple agents can take 3 to 4 weeks. You get the exact date in the proposal.

Will it sound like a robot to my customers?

Before going live, you test the agent and we tune it until it sounds like your best front-desk person. And there's always one configured rule: when a customer asks for a human or the conversation gets complicated, your team steps in.

Does this replace my team?

No — it amplifies it. Systems handle the repetitive: answering the same question, entering data, chasing confirmations. Your team is freed for what truly needs human judgment: closing sales, handling complex cases and growing the business.

What about my data and my customers' data?

Your data is yours. Systems run on enterprise infrastructure, access is limited to what's needed to operate, and we never sell or share information with third parties.

Is there a lock-in?

No. The monthly partnership is month to month. If the system isn't delivering results, you cancel. We'd rather you stay because the number goes up, not because you signed something.
