Growth & Exit Strategies


Builtwins aims to become a leading operating layer for commercial buildings across multiple international markets. Growth is driven by the deployment of the company's physical digital twin platform combined with an agentic layer, increasing adoption within large real estate portfolios and expansion into additional geographies. Under this scenario, Builtwins successfully accelerates commercial adoption and scales internationally.

Exit Scenario 1 – Trade Sale


Builtwins is an attractive acquisition target for a building technology provider, energy management platform, industrial software company or engineering group seeking advanced digital twin and predictive optimisation capabilities. Potential acquirers could include global building technology and infrastructure players looking to strengthen their smart building offering through acquisition rather than internal development, or even AI companies seeking to integrate physical models.

Examples of potential strategic buyers include:

  • Sweco
  • Siemens
  • Honeywell
  • Johnson Controls
  • Equans
  • Anthropic

Exit Scenario 2 – Private Equity


Builtwins could also attract interest from private equity investors seeking scalable software businesses with recurring revenues, international expansion potential and exposure to the growing energy efficiency and smart building market. Such a transaction could provide additional resources to accelerate growth and international expansion, potentially followed by a later strategic acquisition.

In May 2026, such a transaction occured when Bregal Milestone took a majority share in a competitor of Builtwins: meteoviva. This is also what we, at Spreds, saw with the sale of Itineris to Cobepa. Such deals demonstrate the attractiveness of specialised software companies with strong recurring revenues and defensible market positions. 

Two cases


To illustrate the potential range of outcomes, Builtwins has prepared two cases based on the same strategy, business model and market opportunity.

Both cases assume continued deployment of the company's digital twin platform, international expansion, increasing adoption within large real estate portfolios and further development of its AI-powered capabilities.

  • The Management Case reflects the trajectory targeted by management and assumes successful execution of the company's growth plan.
  • The Conservative Case reflects a more cautious outcome in which commercial adoption progresses more gradually and the company reaches a lower scale at exit.

Scenario 1 – Management Case


Scenario 2 – Conservative Case




Key management participation in the share capital


Builtwins has established an equity incentive plan for its CEO, Steven De Laet, and CFO, Edouard Moens de Hase, enabling them to become significant shareholders in the company over time. The plan aligns management's interests with those of investors by directly linking their potential ownership stake to the company's growth and performance. As the shares are acquired from existing shareholders, the plan is non-dilutive for new investors (including the Builtwins 1A compartment of Spreds Finance).

Conditions of the offer


The Builtwins 1A compartment of Spreds Finance would participate in the financing of Builtwins BV/SRL for an amount between €200,000 and €1,200,000 (the “Capital Increase”).

Out of the total amount raised during the offering period, Spreds Finance will invest €1 per Participatory Note, subject to compliance with the conditions applicable to this investment.

Maximum amount of the offer: €1,000,000

Subscription price: Each Participatory Note has a nominal value of €1. In addition, a subscription fee of up to 5% of the nominal value per Participatory Note (i.e. €0.05) will be charged. The total subscription price of a Participatory Note is therefore a maximum of €1.05. The minimum subscription amount is €500 (excluding subscription fees).

Conditions precedent to the offer


The Participatory Notes will only be issued if, within six months following the Closing Date (the “Effective Date”), the following cumulative conditions precedent are fulfilled, prior to Spreds Finance subscribing for shares in Builtwins:

  • The total amount of subscription commitments to this capital increase is at least €200,000 and does not exceed €1,200,000.
  • The capital increase is carried out on the basis of a pre-money valuation of no more than €4,300,000.
  • Spreds Finance participates in the capital increase for an amount equal to the proceeds of the subscription to Participatory Notes of the Builtwins 1A compartment. This amount must be at least €100,000.

Spreds Finance will verify, no later than six months after the Closing Date (the “Effective Date”), i.e. by 28/12/2026, whether these conditions have been met.

If one or more of these conditions have not been satisfied by that date, the Notes will not be issued and investors will be reimbursed for their subscription amount no later than 15 business days after the Effective Date.

Tax Shelter (45%)


This investment qualifies for a tax reduction for Belgian investors under the tax shelter incentive scheme for start-ups. A tax reduction of up to 45% of the total nominal amount invested in Participatory Notes will apply, as the Underlying Assets consist of shares in a micro-enterprise. The total tax benefit is therefore up to €0.45 per Participatory Note.

The available tax shelter budget amounts to €500,000.

Valuation of the company


Builtwins has set a pre-money valuation of €4,300,000. This valuation is based on the technological value already created, commercial validation in real-world deployments, growth potential through validated channel partners, and market comparisons with comparable companies.

Builtwins is not a generic SaaS solution. The software is built around proprietary intellectual property (IP) — more than ten years of specialized R&D that cannot easily be replicated. This technological core creates a structural barrier to entry that differentiates the company from competitors and justifies a valuation above that of a typical early-stage SaaS business.

A. Technology and Market

More than 10 years of specialized R&D

  • The technology is the result of fundamental and applied research at KU Leuven, led by co-founders Dr. Ir. Filip Jorissen and Dr. Ir. Damien Picard. 
  • Cumulative R&D investment during the KU Leuven period: approximately €800,000 (non-indexed), contributed through a commercial licensing agreement with KU Leuven. 
  • Validated through international EU research projects (Horizon 2020 and Horizon Europe). 
  • International frontrunner in physics-based Model Predictive Control (MPC). 
  • Physics-based MPC using Modelica modeling delivers accurate results from day one, remains explainable, and performs robustly outside the training domain — characteristics that black-box machine learning competitors structurally lack. 
  • This approach is the result of years of scientific development and cannot be replicated through standard data-driven methods or off-the-shelf AI tooling. 

Four years of deliberate bootstrapping

  • The team deliberately chose to bootstrap before raising external capital. 
  • Objective: identify and solve technological challenges before scaling the business, thereby reducing financial risk for investors and validating the technology in real buildings. 
  • Result: Builtwins is no longer an early-stage project but an operational company with proven technology and satisfied customers. 

Proven traction: ~17 projects, 0% churn

  • The solution has been successfully deployed in approximately 17 projects/buildings (>300,000 m²), including reference sites such as Herman Teirlinck and VAC Mechelen. 
  • 0% churn — all customers remain active and satisfied. 
  • Average HVAC energy savings of 20–40%. 

B. Financial rationale

Financial plan as foundation

  • The valuation is based on Builtwins’ financial plan (management case and conservative case). 
  • Both scenarios demonstrate a clear and traceable path toward €5 million ARR as an exit threshold. 
  • Serviceable Addressable Market (SAM): €450 million (conservative estimate) up to €1.4 billion based on bottom-up analysis. 

Market comparisons

  • Dnergy (Belgium, comparable approach): approximately €10 million raised, with a last known valuation of €26 million. 
  • PassiveLogic (United States, physics-based digital twins with proprietary hardware): more than $100 million raised to date. 
  • BrainBox AI (Canada, AI-driven HVAC optimization): more than $70 million raised to date. 
The Builtwins valuation of €4.3 million is intentionally positioned at the lower end of the market spectrum.

Conservative multiple

  • Typical valuation multiples for comparable SaaS companies in proptech and energy tech range from 5x to 8x ARR in strategic exit scenarios. 
  • Companies with proprietary, difficult-to-replicate technology generally command structurally higher multiples, as the IP layer represents independent value on top of recurring revenue. 
  • Builtwins deliberately applies a conservative multiple of 3x to 5x forward ARR. 
  • The €4.3 million valuation corresponds to the lower end of that range and includes an implicit discount reflecting the company’s current stage of scale. 

Strategic acquisition value

  • Siemens, Honeywell, and Johnson Controls dominate the building automation market and are directly impacted by the type of technology developed by Builtwins, positioning the company as a potential acquisition target. 
  • The proprietary physics twin is precisely the type of IP that large incumbents are unlikely to develop internally within a short timeframe and are therefore more likely to acquire externally. 
  • The addition of agentic AI services on top of the physics twin also makes major AI platforms potential strategic partners or acquirers.


Confirmed Amounts


Investors are informed that the company has currently obtained non-binding commitments amounting to €300,000.

Use of Proceeds


  • Team (Hiring) – 45%: Recruitment of 7 additional FTEs (sales engineers, implementation specialists and software engineers) to expand the team from 3 to 10 FTEs. This will enable the execution of the existing contractual pipeline and support the scaling of new commercial opportunities.
  • Sales & Marketing – 25%: Expansion of the commercial pipeline beyond the Sweco channel through direct prospecting of building owners and facility managers, marketing campaigns, participation in conferences, and the development of new distribution and partner channels.
  • Product and R&D – 20%: Expansion of the development team and further enhancement of the existing platform. This includes improving the robustness and scalability of the core Model Predictive Control (MPC) algorithms, expanding protocol and hardware compatibility, and reducing onboarding costs. Resources will also be allocated to the development of agentic AI tools that automate the creation of digital twins and building commissioning, as well as to expanding functionalities related to smart energy grids and electrification, including the management of EV charging infrastructure, battery systems, and participation in frequency reserve markets.
  • General & Administrative – 10%: Office, legal, accounting, and IT expenses, as well as the operational overhead required to support the company’s continued growth.
