Broader Perspective and New Solutions

Purchasing consulting services offers several advantages compared to hiring a permanent employee. Consultants bring extensive experience from various industries, enabling fresh perspectives and innovative solutions tailored to your business needs.

Flexibility Without Long-term Commitments – or the Chance to Build a Lasting Partnership

With us, you can bring in the right experts exactly when you need them most – without commitments you’re not ready to make. It’s a flexible and cost-effective way to support your everyday work. But if continuity and long-term collaboration matter more to you, we’re more than happy to build a model where the team and expertise grow alongside your business.

Access to Expertise Even Without Hiring Permission

Often, companies are unable to hire new employees – the hiring approval may be missing, even though the need is urgent. Consulting allows you to access the expertise quickly, easily, and in a scalable and controlled manner.

Expert Leasing and Problem Solving

We offer expertise. Our consulting services cover the full spectrum of software development – from design to delivery, from interfaces to integrations, mobile to embedded systems, and AI to governance models. Most assignments last 6‑18 months, but we’re just as eager to jump into short-term projects or multi-year engagements.

Our Expertise: Roles and Specializations

From us, you can access AI professionals, architects, full-stack developers, data experts, testing and QA specialists, and DevOps professionals.

We are often involved even before the implementation phase. We help refine ideas, plan the way forward, and ensure the direction is right before the big wheel starts turning. Need support in a critical situation? We tackle even the most difficult technical challenges with agility, and bring top-level expertise to clarify your strategic direction when needed. 

Client-Driven: How We Build Teams

We build purpose-driven teams tailored to each client's needs, drawing on expertise from Siili One, our wider group, and our extensive EU-wide network. The team can be local, hybrid, or fully remote, and led from Finland when needed. We don’t follow a one-size-fits-all model, but we’ve served hundreds of clients across Finland and the EU. As our client, we want to understand what works best for you.

A Broad Network at Your Service – Backed by the Entire Siili Group

Siili One combines Siili’s own expert force and a wide partner network into a single service. Our subsidiaries VALA, Supercharge, Integrations Group, and Siili Auto are all part of the offering. Our network spans over 700 partner companies in Finland and the EU – amounting to tens of thousands of professionals.

The Right Expert – From Anywhere

We choose the best possible expert for your situation, needs, and preferred ways of working – whether they come from Siili or our network. This brings flexibility, speed, and scalability.

Pricing Models and Contract Terms

Our pricing is flexible: choose between hourly rates or monthly pricing – or let’s explore new models together that fit the age of AI. We always operate with clear terms: we use the Finnish IT2022 standard contract terms or another suitable model agreed with the client.

It All Starts with Understanding

Buying from us always begins with a conversation. While we use modern information systems to find the right experts, what matters most is first understanding you and your situation – we’re in a people-driven expert business.

Solutions Built Around Your Needs

Whether it's expert leasing or complex problem solving, we approach the need through client understanding. We find the right solution for you – the right person, team, or combination of skills.

A Simple Contact Is All It Takes – We Move Fast

Expert leasing with us is straightforward: reach out, and we’ll quickly find the right professional. Even more demanding challenges are handled smoothly – a single message starts a conversation that leads to concrete action.

Lean but Comprehensive Contracts

Together, we agree on the steps for collaboration, including continuous care and success tracking. Our contracts are lean but cover all the essentials – including warranty terms based on, for example, the Finnish IT2022 standard conditions.

An Ecosystem, Not a Silo

We stand out from competitors by not competing with everyone – we collaborate with all software consulting companies committed to quality. We believe in a model where the client’s best interest comes first, and the right talent is found from the ecosystem – whether it’s from our own people or the tens of thousands of professionals in our partner network.

A Platform, a Workplace, and a Matching Engine

Siili One is a platform, an ecosystem, and a responsible partner. We are both a workplace for over a hundred of Finland’s most experienced software consultants, and an EU-wide matchmaking engine. We know our experts and support their development through training and community. This benefits our clients too – through committed, current, and motivated professionals.

Speed, Reach & Scale: Find Expertise in One Day

Our smallest clients work with one expert for a week, while for the largest, teams can grow to nearly a hundred. When the need is for individual talent, we find the right person within one day of our first discussion in 80% of cases. For demanding roles, team setups, or price points, finding the right experts usually takes 2–5 business days. When we activate our full network of 700+ companies, most matches are found in 1–2 weeks. Fewer than 1 in 10 searches go unmatched.

One Place – All the Expertise

We offer a broad range of capabilities from software development and AI to business development and solving critical challenges. With us, you get the experts, the solutions, and continuous support – all from one place, through one responsible partner.

Subcontracting is a Strategic Way for Us to Strengthen Our Expertise When Needed

Siili One utilizes subcontracting in situations where the client’s need requires rapid response, specialized expertise, or broader arrangements. The goal is not to find the cheapest option but the right professional at the right time for the right need. For us, subcontracting is above all partnership-based collaboration as part of a broader ecosystem. We approach partnerships with the same care as we do our own recruitments.

All Work is Done Within the EU and Under Siili’s Responsibility

Our clients expect all work and data processing to be carried out exclusively within the EU. This is based on the requirements of the EU General Data Protection Regulation (GDPR) and other data protection regulations. Siili has EU offices in Finland, Germany, Poland, Hungary, Austria and the Netherlands. In addition, our partner network includes expert companies widely from Finland and other EU countries, including e.g. Poland, Estonia, Latvia, Lithuania, Czech Republic, Slovakia, Croatia, Hungary, Bulgaria, and Romania.

Quality and Accountability Are Always a Priority

Our subcontractors work the same way as our in-house consultants. They are integrated into client teams, often under the client’s direction, sometimes guided by Siili. All work is delivered under Siili’s name and responsibility. The expectations regarding quality, commitment and working practices are the same. We want to take as good care of our partners as we do of our employees.

This Brings Speed and Flexibility Without Compromises

Subcontracting enables us to bring in specialized expertise flexibly and quickly, depending on the client’s situation. The work is always delivered responsibly, with high quality and in full compliance with applicable legislation – with the client’s goals at the center.

Shared Core, Different Operating Model

Buying from Siili One Ltd (est. 2019) or Siili Solutions Plc (est. 2005) doesn’t mean stepping into entirely different worlds – quite the opposite. Siili One is an integral and inseparable part of the Siili Group: same ownership, same quality, same culture. The difference lies in the operating model and the client target group.

Siili Solutions: Industry-Specific and Strategic Partner, a Pioneer in AI-Powered Development

Our parent company focuses on large and mid-sized client companies as well as the public sector, delivering industry-specific, business-critical solutions. The company executes end-to-end projects that combine strong software development, advanced use of data and AI, and measurable business impact – with the aim of driving sustainable growth.

Siili One: Client-Centric Expertise for Clients of All Sizes

Siili One also delivers with agility – but serves clients of all sizes, as well as the entire Siili Group. From scaleups and startups to SMEs, listed companies, and public organizations. No industry boundaries: what matters most is shared values, especially responsibility. Offering ranges from individual experts to full teams, from mainstream tech to rare special skills, solving complex challenges.

A Wide Network, a Centralized Competitive Edge

Siili One is the competitive edge of the entire Siili Group – now available directly to clients as a service launched in 2025. With our centralized matching engine and curated expert network, we can find the right expert for nearly any need – quickly and reliably. Our network has been systematically developed since 2015 – it now includes tens of thousands of experts across Finland and EU countries.

Over 100 Experienced Experts in Our Core Team

Over 100 consultants at lead level in the permanent core team of Siili One in Finland. Our consultants have an average of 15+ years of experience, and our retention rate (as of 4/2025: 8.8 years) is twice the industry average – providing our clients with predictability and stability.

One Door – Shared Expertise

You can purchase services from any Siili Group company – all backed by the same combined expertise. At Siili One, our focus is on finding productive value-creators fast. Just choose the Siili door that best fits your situation.

Client situations typically fall into two main categories:
1. When you’re looking for an expert or a team to support your operations, or
2. When you need a solution to a business or technology challenge.

Our approach adapts to your situation – below you'll find the questions we ask in each case.

1. Expert Sales – When You’re Looking to Hire an Expert or a Team

We want to understand your goals, technical requirements, team dynamics, and success factors.

To find the most suitable expert or team for your needs, we’ll go through the following topics during our discussion:

• What is the role or team you're looking for?
  E.g. Fullstack Developer, UX Designer, Project Manager, etc.

• What project or task will the expert be working on?

• What is the name and industry of your company?

• When should the expert start, and how long is the assignment expected to last?

• How much of the expert’s time is needed?
  Typically 80% or 100%. Let's tailor it to your needs.

• Where should the work take place?
  Remote, at client site, or hybrid.

• What level of experience is required for the role?
  E.g. senior, lead, or varying levels.

• Does the role require proficiency in a specific language (e.g. a local EU language), or is English sufficient?

• What are the must-have skills or technologies?

• Is a goventment-issued background check (security clearance) needed?
  A prerequisite in some assignments within security-critical industries.
  

• What is the latest date by which you’d want the need to be filled?

• When would you like to receive our proposal?

• Do you have any preferences regarding the source of the expert?
  Do you prefer Siili’s in-house or Finland-based experts, or are you open to leveraging our broader EU-level partner network? If so, do you have a preference for any specific EU country?

• Do you have a preliminary idea of the desired price range or budget?

• Is there anything else we should know?

You’re also welcome to send this information by email to sales@siilione.com. It can help move things along, but there's no need for a full brief. We're here to ask, listen and understand.

2. Sales and Development of Business Solutions – When You're Looking for a Solution to a Technical or Business Challenge

In this case, our approach is always tailored and unique to your situation.

Briefly tell us the core of your problem or need – we’ll determine the right team or setup for the next steps. From there, we’ll identify the best way to proceed together.

Onboarding is the Foundation for Smooth Collaboration

Effective onboarding lays the groundwork for successful cooperation. Siili One consultants work in a wide range of roles, including developers, data experts, designers, project managers, and business consultants. Regardless of the role, it is important that the onboarding process appropriately covers both technical and business perspectives.

Start Preparing Early


Whenever possible, share key tools and documentation before the first working day and clearly communicate the purpose of the project and who it serves. During the first days, it’s helpful to walk through the goals, team practices, and decision-making processes. This helps the consultant understand the big picture and start contributing effectively right from the beginning.

Collaboration Builds Success


Siili One consultants are experienced and self-directed, but a smooth start is always built together. A well-structured onboarding process brings quick, tangible benefits: work flows more easily, misunderstandings are minimized, and the outcome is of higher quality. It's not just about practical arrangements – it’s a true investment in successful collaboration.

A Fast Start Also Supports Cost-Efficiency


When a consultant can quickly focus on the core of the work, the process becomes smoother and value-focused. Good onboarding provides the necessary context and clarifies goals, responsibilities, and ways of working. This shortens the time to productivity and helps establish a shared rhythm.

Experience Brings Confidence from Day One


Siili One consultants bring with them experience, adaptability, and readiness to act. When paired with a well-prepared client, this creates a partnership that is not only efficient but impactful – without compromising on quality.

Wide Range, Expert-Based Pricing

Our services are priced per expert – and our pricing scale is broad. We offer professionals in various roles, at different experience levels, and from multiple locations, both in Finland and across the EU. This enables us to deliver solutions that match your exact needs – including your budget.

Transparent Pricing Ranges

Our goal is to offer the most comprehensive platform for software consulting roles, pricing, and locations. In Finland, we’re already the number One – and we’re gaining strong ground across the EU. As of 2025, our pricing typically ranges from €50 to €150/hour (VAT 0 %), depending on the role, experience level, and location. For the most demanding expert services, such as strategy work, pricing is more tailored and defined case by case based on the scope and content of the service.

Fair and Sustainable Pricing Model

All our pricing is market-based – no overcharging, no undercutting. We’re committed to fair and sustainable collaboration that benefits the client, the expert, and our partners alike.

Collaboration Starts with Your Need, Not the Price

Tell us what kind of expertise you're looking for – we’ll find the right solution and pricing to match. We also explore new models tailored for the age of AI to better meet emerging needs.
