Founder-led software development
We design and build applications for your team and your customers. We connect them to your existing systems and support them after launch.
Work directly with Paweł Paruzel, the founder who designs and develops Syntelligence’s software.

Our AI and SaaS products
What we build
We build AI tools and business applications, and connect the systems you already use.
We build assistants and search tools that work with your documents and business data. They find answers, extract information and connect to your existing systems.

Your team needs answers from scattered documents
Contracts, instructions and proposals are stored in separate files. Your team needs a way to search them and extract the relevant details.
You have an application to build
You know who it’s for and what it needs to do. You need a team to design the first version, build it and get it into users’ hands.
Quotes and reports take too much manual work
Someone gathers data from several sources, runs calculations in a spreadsheet and copies the results into a document. You want that process to take less time and produce fewer errors.
The same data gets entered twice
An order arrives in one application, then someone copies it into CRM or accounting software. Those systems need to exchange data automatically.

Presence connects voice or video conversations to company knowledge and business systems. Depending on the implementation, the AI employee can find an offer, update CRM, book a meeting or hand a case to the team.

Explore our client projects tooHow we work
We define the scope, design the application and build it in short stages. You review progress regularly and test the software with your team before launch.
We learn about your users, their work and the tools they use. Together, we decide what the first release needs to include and agree on scope, schedule and cost.
You review the screens and a clickable prototype before development begins. We map out data sources, integrations and any tasks the AI needs to perform.
Every week, you get new features to test in your browser. You give feedback directly to the people building them.
We test the application, integrations and permissions, migrate the required data and train your users. We also agree on support after launch.
Planning the work
Before quoting, we establish what users need to do and what the software must support. That gives us a defined scope for the first release.
Your proposal
You know the cost before development begins.
Our proposal lists the features, integrations and work included. Maintenance and future changes are agreed separately.
Technical responsibility
Paweł Paruzel leads Syntelligence projects hands-on, from scope and architecture to development. You discuss requirements and trade-offs directly with the person making the technical decisions.
Built for further development
We plan the database and integrations with future features in mind, and document the technical decisions.
Direct technical contact
Discuss requirements and feedback directly with Paweł. The decisions you agree on become part of the scope and the application.
Testing before launch
We test key user tasks, integrations and permissions against the agreed requirements.
Source code and documentation
We hand over the source code, documentation and infrastructure access, and show your team how to use the application.
A prototype before development
You see how the screens look and how users move through the application before we start writing code.
Support after launch
We agree on who monitors the application, handles support requests and makes further changes.
Launch and support
We prepare the application for your data and users, with responsibilities agreed for launch and ongoing support.
Testing and sign-off
You try the test version and give us feedback. We check the software against the agreed features and requirements before you approve it.
Data migration and training
We migrate the data, configure the integrations and show users how to complete their day-to-day tasks.
Access to your code and data
You have access to the source code, database and infrastructure, along with the documentation needed to maintain and develop the application.
Bug fixes included for 90 days
For 90 days after launch, we fix bugs within the agreed scope at no extra charge. New features and changes to requirements are quoted separately.
Describe the application, AI tool or workflow you have in mind. We’ll explain how we can help and what we need to know before providing a quote.
01
Send a short brief and any useful files or links.
02
We review the requirements, data and systems involved.
03
We discuss scope, schedule and cost with you.
The cost depends on what the software needs to do, which systems it connects to and how it will be deployed. We agree the scope first, then provide a quote that sets out the work, schedule and payment terms.
We confirm the schedule once the scope is agreed. You review new features every week, so you can see progress before the full launch.
Code ownership and handover are agreed in the contract. At handover, we provide the repository, documentation and agreed infrastructure access, and identify the external services the application uses.
Yes. We assess the integration options for your CRM, ERP or other tools. We use APIs where available and agree on an alternative way to exchange data if needed.
We review your brief and supporting files, then explain how we can help, what needs clarifying and where to start. If another provider would be a better fit, we’ll let you know.
