What Sobolt does

Sobolt B.V. is a Rotterdam-based AI software company founded in 2016 that builds a modular platform to accelerate the energy transition in the Dutch built environment. Its core products — Hometwin (digital housing dossier), Subsidiecheck (address-level subsidy aggregation), Warmtescan (AI-validated thermal facade scanning), Energieloket (resident information portal), Energieadvies (certified energy advisory), Zonnedakje (solar rooftop analysis), and Isolatieprogramma (end-to-end insulation program outsourcing) — combine computer vision, predictive analytics, and LLM integrations on an API-first, cloud-native architecture (Google Cloud, AWS, Microsoft Azure). The platform is certified ISO 27001, ISO 9001, GDPR-compliant, and WCAG 2.1-accessible, designed for Dutch public-sector buyers.

Sobolt primarily serves four verticals: Dutch municipalities (e.g., Rotterdam, Amersfoort, Tilburg, BEL gemeenten), mortgage providers (Rabobank flagship relationship covering 100,000+ mortgage customers), energy companies, and member organizations such as Vereniging Eigen Huis. Its GTM mixes direct enterprise sales with a white-label / partner channel model, where member organizations and housing corporations deploy Sobolt software to their constituencies. Revenue is generated through multi-year SaaS subscriptions (€500–€12,500/month depending on program tier), per-unit fees for transactional products (€35–€75 per home for Warmtescan, €2,500–€7,500 per municipality for Zonnedakje), and custom co-development services at €125/hour. As of 2024, Sobolt reports 150+ organizational customers and insights delivered to 200,000+ homes, with active operations including Fix-teams in 30+ municipalities for energy-poverty intervention. The company operates as an independent private B.V. with no disclosed external institutional shareholders or parent company.

Broad incumbents

• Eneco: Eneco is a major Dutch energy company offering integrated energy, sustainability, and home services to residents and businesses. As Sobolt's energy-company customer segment, Eneco is both a partner and potential competitor offering similar digital sustainability services at much greater scale.
• Vattenfall (heat/energy transition): Vattenfall is a major European energy company with growing heat-network and residential sustainability offerings in the Netherlands. Comparable to Sobolt as a customer/partner in the energy-company segment, with significantly larger scale and integrated heat-transition capabilities.
• Watershed: Watershed is an enterprise climate platform offering carbon accounting, reporting, and reduction software to large corporates. Comparable to Sobolt in delivering measurable sustainability outcomes via software, though focused on corporate climate disclosure rather than residential energy execution.

Direct peers

• Dexter Energy: Dexter Energy is a Dutch AI-driven energy forecasting and trading platform serving energy companies and municipalities with renewable asset optimization. Comparable to Sobolt in its use of AI for energy transition software in the Dutch market, though more focused on supply-side forecasting than built-environment demand.
• Kelvin: Kelvin is a Dutch/EU SaaS platform that turns building energy data into actionable decarbonization insights for real estate owners and municipalities. It overlaps directly with Sobolt's Hometwin and Energieadvies offerings in serving housing corporations and municipalities with sustainability software.
• Atriensis: Atriensis is a Dutch software and services provider for energy labels, MJOP, and building sustainability data, serving municipalities and real estate owners. Overlaps with Sobolt's energy label automation and housing data modules.
• Reasy: Reasy provides a Dutch resident-facing energy advice and subsidy platform used by municipalities and housing associations. It competes directly with Sobolt's Subsidiecheck and Energieloket products in the same Dutch municipal channel.
• Solar Monkey (Sunrock): Solar Monkey is a Dutch AI-driven solar performance analytics and design platform for installers and municipalities. Direct overlap with Sobolt's Zonnedakje in solar potential analysis for Dutch municipalities and developers.

Emerging players

• Greenly: Greenly is a carbon accounting and climate management SaaS platform serving enterprises. Adjacent to Sobolt in the broader climate-tech SaaS category, addressing sustainability reporting rather than built-environment execution but competing for the same corporate sustainability budget.
• Eturnity: Eturnity is a European SaaS platform for heating and energy planning in buildings, serving installers and housing providers. Comparable to Sobolt's Warmteprogramma and Zonnedakje offerings with a similar B2B SaaS model for energy transition in the built environment.
