From 850 EUR per month. In short Polargate Care is a monthly retainer for software that is already in production: senior maintenance, evolution and support for websites, portals, mobile apps and internal tools, from 850 EUR per month. Requests enter a multi-tenant ServiceDesk and are charged against a contracted pool of hours. An autonomous fix agent prepares changes as pull requests, and a human reviews every diff before anything is merged or deployed. 48h First response on business days 48/48 Audit findings confirmed and closed in one monthly cycle (Hotel Talavera, August 2026) 33 Findings fixed in the same monthly cycle on a second hotel site (Hotel Marien, August 2026) 0 Changes deployed without a human reviewing the diff ## Capabilities We watch what is live, and improve it every quarter. ### Monitoring and evolution Uptime, error and Core Web Vitals monitoring, dependency and security updates, a quarterly roadmap and full release management for web, App Store, Google Play and over-the-air updates, on a monthly senior retainer. From 850 euros a month, minimum three months. That is what a site plus ServiceDesk with 16 maintenance hours and 4 urgent hours is invoiced at. See the service [Monitoring and evolution](https://polargate.ai/services/care/monitoring-and-evolution) Your software stays alive, looked after by the people who built it. ### Maintenance and ServiceDesk A monthly retainer for software already in production: two separate budgets of senior hours, planned maintenance and urgent work, run through a ServiceDesk your team uses by email, with a full audit and a written report every month. From 850 EUR per month, minimum three months. Budget sizes and price reviewed every quarter; anything outside the budgets is quoted before it starts. See the service [Maintenance and ServiceDesk](https://polargate.ai/services/care/maintenance-and-servicedesk) Take a site that is already live and put its defences up, measured before and after. ### Security hardening Hardening for websites and applications that are already in production: headers, content policy, HSTS, cookies, TLS, dependencies and tenant isolation, with a measured grade at the start and a second measurement at the end. Every number in the report carries the host it was measured on, the date and the tool that produced it. Fixed price per engagement, quoted after the diagnosis and split into three phases: diagnosis, hardening, and closing with the link audit and the report. Keeping the posture up afterwards runs as a monthly maintenance fee. We do not sell this by the hour. See the service [Security hardening](https://polargate.ai/services/care/security-hardening) ## How it works 01 Week 1 to 2 ### Takeover and baseline audit We take access to the repository, hosting, database, domain and analytics, then audit the live site from the outside and the code from the inside. You get a ranked list of findings and a short risk register, so you see the real state of what you own before anything is touched. 02 Week 2 to 4 ### Close the critical findings Critical issues go first: security headers, exposed permissions, soft 404s, broken indexation, performance blockers. Each fix travels as a reviewed pull request and is deployed with your approval, so the retainer starts from a clean, known baseline instead of inheriting debt quietly. 03 Every month ### The monthly cycle Tickets flow through the ServiceDesk against your hour pool, the scheduled audit runs over the live site and the repository, and the fix agent proposes changes as pull requests. A human reviews and merges. At the end of the month you get a report of what changed, why and at what cost in hours. 04 Every quarter ### Review and re-plan Every quarter we look at consumption, recurring issues and what the product needs next. The hour pool is resized up or down to match reality, evolution work is agreed as a small roadmap, and anything that has grown into a project is quoted separately instead of eating the retainer. ## What Care is Care is a monthly retainer for software that is already live. Polargate keeps your website, portal, mobile app or internal tool secure, fast, current and improving, month after month, and the person who answers your ticket is the same senior engineer who can read the code. It is maintenance plus evolution: patches and fixes, but also the small improvements a product needs to stay useful. ## Who it is for Mid-market companies, roughly 50 to 500 employees, that depend on a digital surface they cannot staff a full team for. Hotels and hotel groups, industrial and B2B companies, event businesses, corporate portals. Two situations fit best: you launched with Polargate and want that work protected, or you inherited a site from an agency that has gone quiet and you need someone senior to take it over. We work in English, Spanish and Dutch. ## How it works Every request enters a multi-tenant ServiceDesk, by email or through your client portal. Each ticket is triaged, estimated in hours and charged against your monthly pool, which you can watch in real time. An autonomous fix agent classifies the ticket and prepares the change as a pull request in your repository. A human reviews every diff before it merges. Two rules are enforced in the database itself: nothing deploys on its own, and the agent never replies to a client unreviewed. Once a month a scheduled audit runs over the live site and the repository, covering security headers, structured data and AI search readiness, Core Web Vitals, broken routes and dead dependencies. It reports; it does not deploy. For Hotel Marien that routine runs on day one of every month. ## What it costs From 850 EUR per month. The retainer buys a contracted pool of hours split between planned maintenance and urgent work, with clear rules for overflow, and hours left over go into improvements rather than disappearing. The price above the entry level depends on the surface under care: how many applications, how many languages, which integrations, and whether native releases in the App Store and Google Play are in scope. Work that is really a new project is quoted as one, so the retainer never turns into a slow, invisible bill. ## What you get A named senior engineer, a first response within 48 business hours, and a monthly report that says what changed and why. The audits are real work, not a screenshot of a dashboard: the August 2026 cycle on Hotel Talavera confirmed 48 findings and closed them, including 16 real bugs, and the same month on Hotel Marien closed 33. Ownership stays with you: repository, Supabase project, hosting, secrets and domains. If you ever stop, you take the whole stack with a written handover. What you get - Access to the Polargate client portal and ServiceDesk: tickets by email or web, attachments, full history and ratings on close - A contracted hours agreement with two pools, planned maintenance and urgent work, and a consumption balance you can check at any time - A takeover audit of the live site and the repository: security, SEO and AI search readiness, Core Web Vitals, accessibility and dead code, with findings ranked by severity - A monthly maintenance report by email: every change, the reason for it and the hours it used - Reviewed pull requests in your own repository for every fix, dependency bump and framework update - A maintained security baseline: HTTP security headers, CSP and HSTS, row level security on your database, CORS restricted to your domain - A maintained AI search and structured data layer: JSON-LD per page, sitemap with real lastmod, robots policy and bidirectional hreflang - Release management for native apps: over the air updates for JavaScript changes, App Store and Google Play submissions for native ones - A written handover pack: repository, Supabase project, hosting, secrets and domains, ready to leave with whenever you decide ## Proof Concert Music Festival ### From a frozen line-up to an app that updates itself A Spanish summer music festival had its line-up compiled into the app binary and its backend locked inside a no-code platform. Polargate rebuilt the foundation in four days, ten days before the season started. 2026 Read the case [From a frozen line-up to an app that updates itself](https://polargate.ai/work/concert-music-festival) KD.tech ### One platform for a semiconductor company: site, ServiceDesk and admin portal on a single codebase Polargate replaced KD.tech's WordPress site and a planned Odoo rollout with one React and Supabase platform holding the bilingual corporate site, a customer ServiceDesk and an admin portal, and now runs it on a monthly senior retainer. 2026 Read the case [One platform for a semiconductor company: site, ServiceDesk and admin portal on a single codebase](https://polargate.ai/work/kd-tech) Hotel Talavera ### A bilingual hotel website that crawlers and AI assistants can read A 4-star city hotel in Castilla-La Mancha had a website that search engines received as an empty container. Polargate rebuilt it as 16 pre-rendered bilingual URLs and now runs it on a monthly Care retainer with a recurring audit loop. 2026 Read the case [A bilingual hotel website that crawlers and AI assistants can read](https://polargate.ai/work/hotel-talavera) Elite Smart Build ### A custom operating system for Elite Smart Build Elite Smart Build, a Spanish hotel refurbishment contractor working in more than twenty countries, ran every site on spreadsheets and email.

Polargate Care starts at 850 EUR per month. That covers a contracted pool of senior hours split between planned maintenance and urgent work, ServiceDesk and client portal access, the monthly audit and the monthly report. Above the entry level the price depends on how many applications, languages and integrations are covered, and whether App Store and Google Play releases are in scope. Larger evolutions are quoted separately. How is this different from a traditional agency maintenance plan? Three differences. The person answering your ticket is a senior engineer who reads the code, not a first line agent who forwards it. The work is measured in a visible pool of hours, so you can see what you paid for. And an autonomous agent prepares routine fixes as pull requests, which makes small work cheap enough to actually do, while a human still reviews every diff before it merges. Do you maintain a site or app you did not build? Yes, if we can take it over properly. Care starts with an audit of the live site and the repository, so both sides know what is there before anyone commits to hours. Stacks we do not work in, or code we cannot get access to, are not a fit and we say so. If the state is bad, a remediation project comes first and the retainer starts after it. Is it safe to let an AI agent change my production code? The agent never touches production. It classifies the ticket and opens a pull request in your repository, and a human reviews the diff before anything is merged or deployed. Two limits are enforced in the database itself: no automatic deployment and no automatic reply to a client. There is also a daily spending cap. You keep exactly the review trail you would have with a human only team. What happens to hours I do not use, and can I cancel? Unused planned hours go into improvement work rather than being billed for nothing, following the rules written into your contract. Urgent hours sit in a separate pool with their own overflow rules. The retainer runs month to month after an initial minimum term, so you can pause or cancel, and if you leave you get a written handover of repository, backend, hosting, secrets and domains. Do you offer 24/7 support? No. Polargate is a senior led studio, not a call centre, and promising round the clock cover would be dishonest. Urgent tickets have their own pool of hours and are picked up ahead of planned work, with a first response within 48 business hours as the standing commitment. Coverage spans European and American business hours, from UTC minus 5 to UTC plus 1. INITIATE ## Start the engine Tell us what you are building in a few short questions.
