The problem
Three places where a business loses leads before a manager even says hello. One agent closes all three.
A client writes in the evening and gets a reply in the morning. By then they have already booked with whoever answered in a minute. Response speed beats price: the agent replies in seconds, at 3 am too.
80% of questions repeat: how much, how long, how do I book. Paying a person to type the same answers is expensive - and they also take vacations and sick days. The agent takes the routine, people keep the deals.
SaaS bots with "pick a menu option" don't know your prices or services - the client gets annoyed and closes the chat. An agent trained on your data answers the actual question, like an employee who memorized everything and never gets tired.
See it live
One conversation, zero manual entry. While the bot chats on Telegram, the deal moves through your CRM pipeline and every answer lands as a field — in real time.
Formats
Three typical scenarios. Not sure which one is yours - tell me on a call where you lose clients. If a simple €400 automation is enough, I'll say so.
from€500
Answers questions about your services and prices, collects contacts, sends leads straight to you.
For services, clinics, salons, studios
from€1 500
Qualifies the lead, books the appointment, keeps the CRM card updated - like a manager, just around the clock.
For sales teams and client booking
from€3 000
Works with several systems at once: CRM, inventory, calendar, documents. Doesn't just answer - gets things done.
For companies with complex processes
A chat that answers from your knowledge base — without hallucinations. Citations, sources, fallback to a human.
Lead qualification with function calling, scenario classification, automatic pipeline movement in your CRM.
Daily lead pulls, email classification, on-brand content generation, report aggregation.
AmoCRM, HubSpot, Pipedrive, Telegram, WhatsApp, Instagram DM, Slack, Google Workspace.
Not a black box. Dashboard with dialogs, tags, response rating, exports and manual overrides.
GPT-5 / Claude / Gemini — we pick per task and budget. Swap without rewriting the project.
Zero risk
Not verbal promises - actual clauses in the contract we sign before work starts.
The price is set before we start and doesn't change along the way. More scenarios than planned - we agree on a new quote first, then I build.
The launch date is in the contract. If a delay is on me, you get a discount for every week it slips.
Chat history stays with you, personal data is handled under GDPR, models run through European endpoints. No "the data went somewhere, who knows where".
Prompts, knowledge base, integrations and access are all registered to you. Switch developers - the agent keeps working without me.
The process
A typical plan for a chat agent. The multi-tool one goes through the same steps, just with more integrations. Your part takes a couple of hours.
30 minutes on where you lose clients: what people ask, what should happen with a lead, where the agent lives - website, Telegram, WhatsApp. Then a quote and a contract.
I build the base from your price lists, pages and FAQ and tune the tone to your brand. The agent learns to answer like your best manager, not like a bank robot.
CRM, calendar, handover to a human. Then I grill the agent with tricky questions: provocations, typos, off-topic stuff - and tighten up the answers.
We switch it on for real clients. For the first week I watch live conversations and fix the weak spots. You get an admin panel with metrics: chats, leads, conversion.
Pricing
EU agencies: €2,000–8,000
A narrow bot for one job: FAQ, order status or qualification — one channel.
EU agencies: €8,000–20,000
RAG on your data + CRM integration and lead qualification. The most common pick.
EU agencies: €20,000–60,000
An agent that acts, not just answers: multiple tools, integrations and automations.
EU agency prices shown for comparison — the same work at €100–200/hour. On top: API only, €30–80/month at 1000+ dialogs. Final number fixed after a 30-minute call. No mandatory retainer.
Comparison
The job is the same - answer clients fast. Here is what each option costs over a year.
| Agent by buildbyalex | SaaS builder | One more manager | |
|---|---|---|---|
| Upfront | €500-3 000 one-time | €0-100 | recruiting + onboarding |
| Monthly cost | €10-50 for API | €50-500 subscription | from 5 000 zł + social contributions (ZUS) |
| Works 24/7, no days off | yes | 8 hours, vacations, sick leave | |
| Knows your services and prices | canned replies | yes | |
| Writes to CRM and books clients | rarely and poorly | yes | |
| Languages: PL / EN / UA / RU | limited by plan | whatever they happen to speak | |
| Replies in seconds | yes | when not busy | |
| Code and prompts are yours | no, you rent a platform | the knowledge leaves with them |
The agent doesn't replace your team - it takes over the repetitive 80% so people can work on deals instead of copy-paste.
It depends on the number of integrations and how complex the processes are. A simple FAQ agent is a different league than one wiring together CRM, calendar and payments. I don't pull a number out of thin air — we run a short scoping based on your processes and you get a fixed figure before we start.
Real. Function calling, tools, RAG, dialog classification, backend logic, integrations — that's what separates a working agent from a wrapper.
Yes. I work in line with GDPR, sign a data processing agreement, and can host the knowledge base and conversations on EU servers. Your data is never used to train public models and stays with you.
In a well-built RAG — almost never. I enforce a strict-citation mode: if the answer isn't in the corpus, the agent says 'I don't know' and routes to a human. It's controllable.
No. The agent takes over the repetitive, time-eating tasks — FAQ, lead qualification, order status — and escalates the harder cases to a human with a ready summary. Your team gets time back for the work that actually needs people.
Usually 2–6 months, depending on query volume. We calculate the break-even point before we start — from the number of conversations the agent will take over and the team hours it frees up. If the numbers don't add up, I'll say so straight.
Through the native API. AmoCRM v4, HubSpot, Pipedrive — they all support webhooks and REST. The bot tags, moves through the pipeline, leaves notes. Everything a manager does manually — automatic.
A focused bot — a FAQ assistant or lead qualifier — ships in 1–2 weeks; an agent with RAG and a CRM integration takes 3–4 weeks. Running costs are mostly API: a typical agent on GPT-4o-mini / Gemini Flash sits around €30–80/month at 1000+ dialogs. The date and cost are in writing before we start.
Yes. A single agent handles Polish, Russian, Ukrainian and English, replying in whatever language the customer writes in. The RAG layer is built on your documents and knowledge base, so answers come from your sources — not the model's general knowledge. Your data stays yours and is never used to train anyone else's model.
We work across all of Poland and remotely — Warsaw, Kraków, Wrocław, Gdańsk, Poznań or a smaller town, it makes no difference. Calls, demos and handover happen online; the contract and payment are remote. An in-person meeting in Warsaw is available on request.
What clients say
A few words from founders and teams I've shipped for.
Launched our store in 11 days — multilingual, fast, and already on page one for three of our main keywords.
The Telegram bot handles the first conversation with every lead now. My sales rep only steps in when the deal is hot.
Leads land in our CRM with every field already filled. No more copy-pasting from chats — the pipeline moves itself.
Shipped to the App Store and Google Play in three weeks. The handover docs let my team take it from there without me.
Set up our Google and Meta ads from zero. Cost per lead dropped by about a third in the first month.
He rebuilt the site and six weeks later ChatGPT was recommending us by name. Didn't know that was even possible.
Free 30-minute call. No sales pitch — just a real conversation about what you need and whether I'm the right person to build it.
No sales pitch — just a clear read on your scope.
