What Boldr does
Boldr is a smart HVAC technology company founded in 2022 that designs universal smart thermostats and controllers for residential climate management. Its core product line consists of the Boldr Universal Thermostat (compatible with both central ducted and ductless HVAC systems) and the Boldr Smart Controller (designed specifically for ductless mini-splits and room air conditioners), both featuring presence-based sensing, zonal climate control, and integration with existing HVAC infrastructure rather than requiring full-system replacement.
The company operates a platform-plus-hardware architecture, pairing its devices with the Boldr Pro Platform — a contractor-facing tool for fleet management, predictive maintenance diagnostics, customer retention touchpoints, and business operations — and the Boldr Energy App, a free homeowner-facing mobile application offering real-time energy monitoring, smart scheduling, remote access, presence sensing, multi-property management, and humidity monitoring. Boldr sells primarily through HVAC contractors via the Boldr Pro program, which bundles dedicated account management, live phone/email support (US toll-free 888-269-1303, Eastern Time hours), and training; secondary channels include wholesale distributor networks and indirect contractor installations reaching residential consumers.
Boldr generates revenue through one-time hardware sales (thermostats and controllers at approximately $400 per unit, plus the Boldr Kelvin infrared heater line) and a recurring subscription component via the Boldr Pro Platform. The company has raised approximately $12.75 million across seven funding events between June 2022 and May 2026, with investors including Techstars (Stockholm accelerator), Ada Ventures, Norrsken VC, Futurology Ventures (which led the October 2024 round), Unconventional Ventures (which led the May 2026 $5M round), Prosegur, and S20 Fund. Boldr is led by three co-founders — Madiyar Ablyazov (CEO), Matheus Marotzke (CTO), and Toma Paro (COO) — with 11-50 employees and a stated dual presence between London (HQ) and US operations.

Boldr competitors and assessment
Company assessmentDirect peers
- Ecobee: Smart thermostat maker (now owned by Generac) competing in the same residential smart-thermostat category with energy-monitoring, scheduling, and HVAC integration features. Most direct comparable on product functionality and target end-user.
Broad incumbents
- Google Nest: Market-leading smart thermostat line owned by Google/Alphabet, distributed through retail and HVAC channels. Competes with Boldr for both consumer mindshare and contractor default installations, with vastly larger marketing and engineering resources.
- Resideo (Honeywell Home): Spun off from Honeywell and a major HVAC controls incumbent selling Honeywell Home branded smart thermostats, zoning, and contractor services tools. Competes in both Boldr's thermostat and contractor-platform categories through established wholesale distribution.
- Carrier: Major HVAC OEM with growing smart-thermostat and controls portfolio (including Carrier Smart Thermostat). Sets contractor default-install preferences that Boldr must dislodge in commercial and residential channels.
- Trane Technologies: Global HVAC OEM with smart-thermostat offerings (including Nexia) and a deep contractor network. Competes indirectly as the equipment manufacturer whose installed base Boldr thermostats must integrate with.
- Mitsubishi Electric Trane HVAC US: Joint venture selling Mitsubishi ductless mini-split systems with proprietary controls (kumo cloud). Competes in the ductless category Boldr's Smart Controller targets, with strong contractor loyalty programs.
Emerging players
- Sensibo: Smart AC controller focused on mini-splits and window A/C units, directly overlapping with Boldr's Smart Controller and universal mini-split value proposition. Closely comparable on ductless focus and homeowner app experience.
- Mysa: Smart thermostat company targeting high-voltage electric heating and mini-splits, with a consumer-direct channel. Competes for the same energy-conscious homeowner and electrification-driven install base as Boldr.
- Flair: Smart vents and room-level climate control system that, like Boldr, emphasizes zonal control to reduce HVAC energy waste. Overlaps with Boldr's zonal-control feature and energy-monitoring capabilities.
- Cielo WiGle: Smart thermostat and controller line specializing in mini-split and window AC retrofits. Comparable to Boldr Smart Controller in bringing smart features to ductless systems.
