AI trained for ecommerce · LATAM

sell and support,
at scale.

Every unanswered message is a sale going cold. Steff closes it: replies in under 9 seconds, recommends, builds checkout and recovers the cart the customer was about to leave. That is what you hire — more revenue from the same traffic, with no extra shifts.

00 / the night

a message at 11:14 p.m.
a sale that does not walk away.

This is the story of what happens when you hire heysteff — and of the revenue you stop losing when nobody on the team is awake.

  1. 11:14 p.m.

    The customer asks

    “Do you have the kit in M?”. With no reply they go to another store. The cart stays open and goes cold. That sale does not come back.

  2. 11:14 p.m.

    Steff acts

    It checks live stock, confirms the size and suggests the poles. First reply in under 9 seconds. Your team is still asleep.

  3. 11:15 p.m.

    The sale closes

    Checkout in the same chat. +$48.900 in seven seconds. That is the gain: the sale that today evaporates between shifts.

without steff

the night eats the sale.

  • The message sits on read until morning.
  • The cart is abandoned. The automatic email does not unlock the objection.
  • Your team walks into 40 “where is my order?” tickets.

with heysteff

the same night, the sale is yours.

  • Replies in < 9s, 24/7, in your brand voice.

what you gain when you hire us

More money from the same traffic

You do not need more ads. You close what already comes in: carts that return, checkouts born in chat, sales at 11 p.m.

A team that does not burn out

70–90% of repetitive tickets (order, size, tracking) stop being copy-paste. People stay for the work that needs judgment.

An operation that does not sleep

The same tone at 3 a.m. as at 3 p.m. $0 setup, a real Free plan with no card, and you cancel whenever you want.

01 / impact

measurable impact on your operation.

Figures we publish and measure. What counts, what does not, and what we compare against is in the methodology — these are not unsupported marketing averages.

< 9s

First-response time

Immediate 24/7 support so you capture intent before the customer cools off.

87%

Resolved without a human

Repetitive order, catalog and cart questions close on their own. The rest escalate to your team.

4.2×

Cart recovery

Conversational follow-up versus no follow-up (or only the platform's automatic email).

70–90%

Repetitive tickets resolved

The range we see in ecommerce operations: Steff does not replace human judgment — it replaces copy-paste.

24/7

Coverage without shifts

The same brand voice at 3 a.m. as at 3 p.m. You pause the bot per conversation, channel or workspace.

$0

Implementation cost

Starter the same day. Pro in 3–7 days. No lock-in. Cancel whenever you want.

02 / product

AI built for ecommerce, not generic tickets.

Steff is not a button tree. It reads intent, uses your catalog and your tools, and closes — or escalates — in your brand's voice.

Turn conversations into sales

It recommends products, answers size or stock questions and generates the payment link inside the chat. The customer does not jump to another app: checkout starts on WhatsApp, Instagram or Messenger.

Recover revenue lost to abandonment

On Shopify, abandonment triggers an automatic follow-up on the channel the customer already used. It offers the right incentive and reopens checkout. No spam: you set the rules.

24/7 support, consistent with your brand

You upload policies, FAQs and examples. You adjust formality and proactivity. Steff does not invent lead times or prices: it answers with what you taught it, and if it is unsure, it escalates.

Fast, adjustable setup

You connect channels, upload the catalog or link the store. Starter is live the same day. Copilot mode lets a human take any conversation in one click.

Control and organize post-purchase

Order status, exchanges, returns, payment proofs and voice notes. Steff reads the image, transcribes the audio and replies with context — or opens a ticket if there is anger or a claim.

Early pilot customers. We will publish names when the case is closed together — until then, these are the dashboard metrics, the same ones in the methodology.

Outdoor store with 4 storefronts (.cl, .com, .mx, .co). Before: two people answering the same questions all day on WhatsApp, Instagram and email.

the sale you lose when nobody replies.

The platform's automatic email does not unlock an objection. Steff follows up on WhatsApp or email, answers the question and reopens checkout. The 4.2× figure compares that conversational follow-up against no active follow-up.

05 / stack

it connects to the systems you already use.

Shopify is native (OAuth, catalog, orders and carts). WooCommerce, TiendaNube, HubSpot, Defontana or your ERP come in through HTTP tools and webhooks: the agent works with live data, not a static FAQ.

⬢

Your site and catalog

Native Shopify. WooCommerce and TiendaNube via API. Stock, variants and checkout from the chat.

  • Shopify OAuth
  • Woo · TiendaNube
  • Catalog via tools

ERP, CRM and logistics

We do not ask you to abandon your stack. If it exposes HTTP, Steff looks up orders, couriers or CRM in the same conversation.

  • HubSpot · Defontana
  • Webhooks + REST
  • Polling every 5 min

10 / questions

what people ask before booking.

Does Steff replace my team?

No. It resolves 70% to 90% of repetitive questions and escalates anything that needs judgment (out-of-policy refunds, claims, very upset customers). You define the keywords that always escalate, and any human takes over the conversation in one click with copilot mode.

What makes heysteff different?

One agent that answers, sells and recovers carts in the same inbox — WhatsApp, Instagram, Messenger and Gmail — with native Shopify and API tools for everything else. Your brand's voice, pause in one click, and published figures with a methodology. A real Free plan, no setup fee.

Does it work if I do not use Shopify?

Yes. WooCommerce, TiendaNube, HubSpot, Defontana or your own system connect through the tool builder. Automatic abandoned-cart recovery is Shopify-specific; on other platforms the agent still answers, sells and books appointments.

Is there an implementation fee? How long does it take?

Zero setup cost. Starter is live the same day. Pro, 3 to 7 days. Max, 2 to 3 weeks with dedicated onboarding.

Is there a lock-in contract?

No. You cancel whenever you want. Free does not ask for a card. Payments are month to month, or annual with 20% off.

How much does it cost?

Free 0 USD/month. Starter 149, Pro 299 (the most chosen for ecommerce, with 1 Shopify store and carts), Max 549. Billed per resolved conversation. Details under pricing.
