Four ways lead response quietly kills revenue.

The 30-minute gap

When a lead messages at 9 PM Tuesday, they're talking to three of your competitors by 9 AM Wednesday. Response speed beats response quality 9 times out of 10.

The consistency drift

Your top salesperson closes 35%. Your newest rep closes 12%. It's not talent — it's script adherence. Manual processes drift. AI that follows your script doesn't.

The channel fragmentation

WhatsApp Business App. Instagram DMs. Website chat. Telegram. Each one is a separate inbox with separate history. Leads fall between them every day.

The CRM lag

By the time a deal lands in Pipedrive, it's stale. Custom fields blank. Follow-ups missed. Pipeline shows revenue that isn't there.

Dialogex runs your exact sales process. Not a generative improv show.

FSM-based conversation engine

Under the hood, Dialogex uses a finite state machine with AI-powered branching. Deterministic where it matters (qualification, pricing rules, escalation). AI-flexible where it helps (tone, objections, natural phrasing). Your playbook is the contract.

Buyer persona AI testing

Ten AI-simulated buyers stress-test your script — skeptic, price-sensitive, competitor-fisher, time-waster, technical evaluator. Each conversation scored. You see where the script breaks, fix it, then real leads talk to it.

Unified channels + native CRM

WhatsApp, Telegram, Instagram, web widget — one inbox, one history per lead. Pipedrive two-way field-level integration. Built-in CRM for teams that don't have one yet.

8-language native support

European SMBs live in 8 languages. Dialogex speaks Portuguese, Spanish, English, German, French, Italian, Dutch, and Russian — native, not translated.

Live in under a day — if you know what you want.

Why this exists.

Vladislav Umnov — Staff AI Engineer

17 years building production software. Previously built LampaBot — an AI sales agent for Russian real estate — processing thousands of leads across 2+ years in production.

I built Dialogex because every AI sales product I tried either hallucinated away my pricing rules, lost conversation context after 3 turns, or required a PhD to configure.

The FSM-based approach + automated persona testing isn't marketing novelty. It's what I built for myself after monolithic prompts burned me on LampaBot v1.

I'm building this for European SMBs who've been burned by chatbot promises before. If that's you, we should talk.

Frequently asked questions

Is this production-ready?

Dialogex is running in production today with a 90-95% success rate in persona testing. The core conversation engine has LampaBot-level hardening. Some peripheral features are still being polished (advanced analytics, custom integrations beyond Pipedrive). Early customers get direct input on the roadmap.

What happens if the AI says something wrong?

Three layers of defense. First, the FSM constrains the AI to your approved script — it can't offer discounts you didn't authorize. Second, persona testing catches drift before production. Third, the AI detects its own uncertainty and transfers to your team.

GDPR compliance?

Hosted on Hetzner Germany (EU data residency). LLM calls route through Anthropic EU and OpenAI EU. DPA template provided on signup. Data retention configurable per client.

Which languages really work well?

Tested heavily in English, Russian, Portuguese, and Spanish. The other 4 languages (German, French, Italian, Dutch) are functional but less battle-tested. Tell us which language matters for you and we'll prioritize tuning.

What's the onboarding time?

Realistic: 2-4 hours of your time spread over 2 days. Conversational AI onboarding covers 80%, then 1-2 calls to refine edge cases and connect channels.

Can I cancel?

All self-serve tiers (Free, Starter, Professional, Growth) are month-to-month — cancel anytime. Enterprise and Design Partner Program agreements have terms specific to the contract.

Who owns the conversation data?

You do. Export anytime, CSV or API. We don't train models on your conversations.
