KALLISTACK was founded in Bastia by Alexandre Sciacca, a full-stack engineer with more than ten years of experience.
You talk directly to the person who designs and builds your project, from the first meeting to maintenance. We work with SMEs, startups and public bodies, in Corsica and beyond.
Frequently asked questions.
Where in Corsica do you work?
We are based in Bastia and work across the whole of Corsica: Haute-Corse (Bastia, Cap Corse, Balagne, Corte, the eastern plain) as well as Corse-du-Sud (Ajaccio, Porto-Vecchio, Propriano). Websites, software, AI and consulting also work very well remotely: we support clients on the French mainland and abroad, in French or English.
How much does a website cost?
It depends on the project: a showcase site of a few pages, an online shop and a business application differ in scope and budget. After a first conversation about your goals, you receive a clear, itemised quote with no jargon. We reply to every enquiry within 48 hours.
Can you bring artificial intelligence into my business?
Yes. We first identify the tasks where AI genuinely saves time: answering your customers' frequent questions, sorting and summarising documents, extracting invoice data, preparing drafts. We then set up the right solution (an assistant connected to your content, automation, or AI hosted on your own server when confidentiality requires it) and train your team to use it.
Do you supply IT hardware?
Yes. We advise on, supply, install and maintain workstations, servers, NAS, Wi-Fi networks and AI servers for businesses. We also build custom PCs and repair computers, for businesses and individuals alike, in Bastia and across Corsica.
Will my website rank well on Google?
Every site is built for search from the start: fast, mobile-friendly pages, a clear structure, structured data and content written around what your customers search for. We can then support you over time: Google Business Profile, rank tracking, new content. Nobody can honestly promise the top spot, but a well-built site starts with a real head start.
I'm not technical: is that a problem?
Not at all. Tell us what you want to achieve: we turn your need into a solution, explain every choice in plain language and remain your single point of contact, from the first meeting to maintenance.
Who looks after the site or software after launch?
We can host it, monitor it, back it up and keep it evolving, with the same point of contact as at launch. If you would rather manage it yourself, we train you to do so.
What other services do you offer?
Beyond the web, AI and hardware, we build custom software and SaaS, create brand identities and digital marketing campaigns, shoot drone aerial photography, run penetration tests and cybersecurity audits, develop smart contracts and video games, and offer consulting and training. One point of contact for all your digital projects.
