We are engineers and marketers with production experience. AI handles the routine; we invest the time in architecture, business and results. We do three things: build software, automate operations and bring in customers.
manifesto · why we do this
We came together as a team of specialists — each grew for years in their field inside large companies: development and integrations, paid advertising for leading CIS and US e-commerce, SEO, business analysis. First we brought AI into our own processes and saw how much it changes speed and cost. Now we do the same for others: fast, transparent and with no lock-in to a contractor.
Landing pages, corporate sites, online stores, portals and admin panels. On 1C-Bitrix, WordPress or a custom framework, from a simple storefront to a high-load service.
iOS and Android apps: cross-platform for speed and budget, or native where it actually matters.
Backend, APIs, automation, parsers. We connect your site to 1C, CRM, payment and inventory systems so data moves on its own.
We plug AI into the processes where people burn hours on routine. Not a chatbot for show, but tools that actually take load off sales, support and finance and turn data into decisions.
An assistant in your CRM: deal summaries, rep prompts, auto-filled fields and next-step suggestions.
Calls transcribed to text, scored against your script, tagged and sentiment-checked. Every call reviewed without manual listening.
AI rates how reps handle clients: script adherence, stop-words, missed deals. Objective, on every conversation.
Dashboards across funnel, sources and reps. Revenue forecasts and bottleneck alerts, not spreadsheets for their own sake.
AI knows your catalog, prices and specs and answers from it, to clients and reps alike. Fewer mistakes, faster replies.
Bots on the site, Telegram and WhatsApp that answer to the point 24/7 and hand off to a human when needed.
Auto-reconciliation, invoice and quote generation, receivables control, scheduled reports without manual crunching.
Every lead is qualified, routed to the right rep and answered instantly, any time, even at night.
Search across company docs, assistants for staff, automation of routine tasks and correspondence.

We set up and run paid traffic where it pays off. Google Ads, Yandex Direct and Bing, CIS and US markets, in two languages. We don't burn budget on impressions; we drive leads and sales.
Years of work and dozens of projects across niches: e-commerce and online stores, building materials and home goods, services, B2B, niche and complex products. We run bilingual campaigns across CIS and the US at once, working with Google Shopping and Merchant Center, product feeds, remarketing and full-funnel analytics.
We know ads beyond the dashboard: feeds, bidding, attribution, placement and negative-keyword cleanup. We understand where leads actually come from instead of trusting the platform's pretty automated reports.
Payment models
Pay for actual hours worked with transparent time tracking. Handy at the start and for one-off tasks.
A percentage of the orders the ads bring in. We're invested in sales, not in spent budget.
A small hourly fee plus a percentage of orders. Balance of stability for us and motivation on results.
Organic traffic that brings in leads for years with no cost per click. We do SEO like engineers: technical foundation and site structure first, then semantics and content for real demand. The track is led by a senior, and pairing it with paid ads and analytics shows the whole traffic picture.
Speed, indexing, clean structure and markup. We fix what blocks ranking at the code level, not cosmetically. Core Web Vitals, clean URLs, sitemap, hreflang, Schema.org.
We build the semantic core, cluster queries and create landing pages for real demand. Content that ranks and sells, not filler for word count.
Promotion for online stores and services: product pages, filters, categories, geo-targeting. We grow organic traffic and leads, not rankings for their own sake.

Behind the team are projects for leading CIS and US e-commerce and dozens of tasks for private businesses across niches. Some are under NDA, so these are generalised — we'll share real names, numbers and accounts on a call.
A system for a door factory: pulls orders from 1C over OData and shows statuses, stages and production deadlines in real time. The shop floor sees the plan, the manager sees readiness.
An automated parser of competitors' prices, stock and reviews. It collects data on a schedule and sends reports: who raised prices, who ran out of stock, what people write in reviews.
A full e-commerce build: catalog, payments, delivery, customer account. Stock, prices and orders sync with 1C, and product feeds flow into Google Shopping automatically.
The customer builds a product by parameters: size, color, material, hardware, and instantly sees the price and the look. The finished configuration goes into the order and into production with no manager.
Ran Google Ads for a US door retailer: rebuilt campaigns from Performance Max to Standard Shopping, fixed six product feeds and cleaned up Merchant Center. Leads come through calls and forms.
Connected call transcription and analysis to Bitrix24: every conversation is turned into text, scored against the script and tagged. The manager sees the team's quality without listening manually.
Vibecoding is not blind code generation and not magic. The engineer sets the architecture and makes the decisions; AI handles the routine: boilerplate modules, glue code, tests. The human owns what matters, the machine speeds up what repeats. What drops is hours spent, not quality.
We dig into the task and your business. We design the structure and stack before the first line of code, so we don't rewrite half the project later.
We quickly assemble a working skeleton. You see a clickable result instead of a forty-page spec, and changes happen early, where they're cheap.
We write code together with AI tools. This is the main time saving: what takes a week by hand takes us a couple of days.
Every piece of code goes through a human: security, performance, readability. AI is never left unsupervised.
We hand over the project with full documentation. Any developer can maintain it afterwards, not only us.
It wasn't a job posting that brought us together, but shared experience: each of us grew for years as a specialist inside large companies and private projects. Not all-rounder juniors, but seniors who built processes, budgets and products themselves — and now amplify them with AI.
Project management and development (PHP, SQL, Python, Perl), CRM, CMS and telephony integrations. Formerly head of marketing and digitalization at large companies. Sees the project as both an engineer and a business.
Vast experience and dozens of projects: leading CIS and US e-commerce plus private businesses across niches. Knows ads beyond the dashboard — feeds, bidding, attribution, funnel analytics.
Has sold diverse products across the US and CIS and talks to people in a way that makes them buy — with conversion worth being proud of. He hears what the client actually needs and helps us shape the product around that demand and present it simply and clearly.
Seasoned lead of organic growth: technical SEO, semantics, content and commercial promotion for online stores. Works for results in traffic and leads.
Specialist in interfaces and markup: tidy storefronts, responsive layouts and accessibility. Makes fast-built things look and feel premium.
A project manager from software companies and a business analyst. Turns a business goal into a clear spec and keeps deadlines, transparency and documentation.
// names, portfolios and roles for your project — on a call
Deep experience across several fields at once: development and integrations for CIS and US markets, AI automation on top of CRM and 1C, and paid advertising and SEO in e-commerce, B2B, services and niche products. Behind us are roles as heads of marketing, SEO and projects in large companies. We see the whole project: from code to lead to revenue.
We've written production code and run ads ourselves. We speak both code and business, with no broken-telephone in between.
The project won't fall apart on the second feature or turn into a mess. We lay a foundation you can build on.
We don't overbuild where simpler works. We offer options, not a single invoice with no explanation.
The code is yours, the stack is transparent, the docs are in your hands, the ad accounts are yours. You can leave any time.
We don't dump prices or cut corners on quality. We just spend fewer hours: what a typical studio writes by hand, we assemble with AI several times faster, and quality is held by engineer review, not by hours logged. Fewer hours means a smaller bill, with no hidden lines in the estimate.
* the speed-up is for typical tasks and may differ on complex projects
Every project ships with documentation: how the architecture works, how to deploy, how to maintain and where everything lives. So you don't depend on one contractor and can hand the project to anyone.
