AI Tools & Playbooks

The AI stack running underneath every Xtendly engagement.

"AI-powered humans" isn't a slogan — it's the specific software your SDR or AI Engineer works inside every day. Here's exactly what's in the stack, what each tool does, and why it's part of the playbook.

Why we show you the stack instead of hiding it

Optional

Our AI tools are available add-ons — use ours, use yours, or mix and match

7 gates

Verification checkpoints an AI-assisted engineering task must pass before it's marked done

Black boxes — every qualified lead, booked meeting, and shipped commit is logged and reviewable

Why this page exists

You're not just hiring a person. You're hiring the system behind them.

When you hire an Xtendly SDR or AI Engineer, they show up trained on a stack that would normally take you months to evaluate, license, and integrate yourself. These tools are optional add-ons, not a hidden markup — and because we're tool-agnostic, we're just as happy working inside your existing stack. This page is the honest inventory of what we've built and know works, and why it earned a place in our playbook.

For SDR Services

The AI stack behind every SDR engagement

Your human SDR runs outbound with Xtendly's own prospecting playbooks. Underneath that, two AI platforms handle the always-on layer — catching inbound replies the second they land and keeping your storefront and marketing content moving without waiting on a human's calendar.

Pippify

Your AI SDR that qualifies, books, and closes

Inbound qualification

✓Engages every inbound lead the moment it arrives and scores intent with 95%+ qualification accuracy
✓Books meetings directly onto your reps' calendars — only the ones that clear your qualification bar
✓Runs automatic follow-ups and reminders so deals keep moving without anyone chasing
✓Syncs with HubSpot, Salesforce, Zoho, Google Calendar, WhatsApp, and the rest of your existing stack

Why Xtendly uses it: your outbound SDR is one person with finite hours. Pippify is the net underneath — it catches every inbound reply, chat, and web form lead the instant it arrives, so nothing goes cold waiting on human bandwidth.

Prosperna

AI-powered storefront & marketing assistant

Content & engagement

✓AI-generated product descriptions, SEO tags, blog posts, and landing pages, on brand and in minutes
✓AI chatbots handle inquiries and route qualified conversations across Facebook, email, and SMS
✓Drag-and-drop page builder — the same one Xtendly uses to publish its own site
✓Pre-integrated local payments and logistics, so a lead can go from inquiry to checkout in one flow

Why Xtendly uses it: Prosperna was founded by Xtendly's own CEO, so it's the platform we trust to turn inbound interest into an on-brand, always-responsive storefront — no separate agency or build cycle required.

For AI Engineering

Verification-gated tooling for AI-assisted engineering

"AI-accelerated" should never mean "unreviewed." Xtendly's AI Engineers write and ship code with the help of AI coding agents — but every task they touch runs through a governance layer that sits on top of the agent, not inside it, so "done" is never just the agent's word.

Proprietary-grade governance layer built into every AI Engineer's workflow

Engineering QA

Locked acceptance tests. The tests a task is judged against are hash-locked before work starts, so an agent can't quietly rewrite the test it's supposed to pass.

External verify, not self-declaration. A task can't be marked done until the real toolchain — tests, lint, typecheck, build — comes back green.

Adversarial review. A second, independent review pass catches "tests pass but the test was inadequate" — the failure mode a same-model check misses.

Held-out audits. Periodic regression checks run against material the implementing agent never saw, catching drift a visible test suite wouldn't.

No vacuous passes. A feature has to ship a test that actually fails without the change — an empty or trivial check is flagged, not accepted.

Human-owned judgment calls. Mid-task decisions that need taste — not just correctness — get surfaced for a person to accept or redirect, instead of the agent silently deciding.

Why Xtendly uses it: AI-assisted development moves fast enough that self-graded "it works" isn't a real quality bar. This layer means every commit your AI Engineer ships rests on an external check, not the model's own say-so — the same standard we'd want if it were our own production system.

How this shows up in your engagement

Tools you inherit, not tools you have to manage

01 — Optional

Available as an add-on

Want us to run on the tools we've built and trust? That's an added subscription. Prefer your own stack? We're tool-agnostic and will work inside it instead.

02 — Configured

Wired to your stack

CRM, calendar, and codebase integrations are set up during onboarding as part of the engagement, not billed as a separate project.

03 — Logged

Reviewable by you

Every AI action — a qualified lead, a booked meeting, a shipped commit — is tied to an audit trail you can inspect anytime.

04 — Evolving

Proven before it ships

We evaluate new AI tooling continuously and only fold it into the standard playbook once it's proven in production, not on a demo.

Frequently asked questions

Everything you need to know about Xtendly's AI tools

Do I pay extra for these AI tools? +

These tools are optional and do require an additional subscription fee if you want us to use the tools we've built and know work. That said, we're tool-agnostic and use whatever it takes to get the job done — including your existing stack, if that's the better fit.

Which AI tools does Xtendly use for SDR services? +

Xtendly SDRs work alongside Pippify, an AI SDR that qualifies inbound leads in real time and books meetings directly on your calendar, and Prosperna, an AI-powered storefront and marketing platform that generates on-brand content and engages customers across channels the moment they show intent.

What AI tooling supports Xtendly's AI Engineers? +

Xtendly AI Engineers ship through a governance layer that sits on top of AI coding agents. It locks acceptance tests so they can't be silently edited, requires an external adversarial review before any task is marked done, and runs held-out regression audits the implementing agent never sees.

Are these AI tools a replacement for the human SDR or engineer? +

No. The tools handle the repetitive, always-on layer of the work — real-time qualification, content generation, test verification — while your dedicated Xtendly SDR or AI Engineer owns strategy, judgment calls, and the relationship with your team.

How does Xtendly keep AI-generated work from being a black box? +

Every AI action is logged and tied to an audit trail you can inspect. On the engineering side specifically, no task is marked complete on the agent's own word — it has to pass an external, independently verified check first.

Will these AI tools work with our existing CRM or codebase? +

Yes. Integrations with your CRM, calendar, and codebase are configured during onboarding as part of the engagement, not sold as a separate implementation project.

Can we request a different AI tool or opt out of one? +

Yes. The stack described here is our default playbook because it's proven in production, but we'll work within your existing tools where it makes sense — particularly on the engineering side, where clients often already have CI and review tooling in place.
