Weekly Venture Deal Tracker: FieldPulse, Bisly, Carbelim

BuiltWorlds’ Venture & Investments research team is dedicated to meticulously tracking venture activity happening throughout the built environment—as evidenced by our recently released Q2 Venture Report. That includes charting each publicly-announced, AEC-related venture deal that takes place. This information is available exclusively to our Venture & Investment Research Track members—accessible via our Venture Dashboard. However, each week, we like to give the industry at large a glimpse into the types and sizes of deals taking place around the world. We call this our Weekly Venture Deal Tracker.

This week in built environment venture, we saw a number of deals place around the world, including three involving the AEC industry startups FieldPulse, Bisly, and Carbelim.

FieldPulse Raises $50 Million

FieldPulse, a customizable field service management (FSM) software provider, secured $50 million in Series C funding led by Fulcrum Equity Partners, with participation from Catalyst Investors. The investment follows the company’s four fold growth over 21 months since its Series B and the launch of Field Intelligence, an AI-powered scheduling solution.

The funding will support AI-driven product development, deeper platform customization, and expansion of the customer success team. The FSM market, valued at $4–5 billion in 2024, is projected to grow to over $11 billion by 2032, fueled by digital transformation and automation trends.

Fulcrum, which also led the Series B, reaffirmed its confidence in FieldPulse’s execution and customer-first approach. Catalyst joins as a new strategic partner, citing the company’s potential to lead the shift toward AI-enabled field service operations. Learn more

Bisly Raises €4.3 Million

Estonian smart building automation company Bisly has raised €4.3 million in a round led by 2C Ventures, with participation from existing backers Aconterra, Pinorena, Foxway founders, and Estonia’s state-backed SmartCap Green Fund (part of the EU’s NextGenerationEU plan). Already the leading provider in Estonia—where most new apartments sold in 2024 include Bisly tech—the company will use the funds to deepen its presence in Germany and the UK, and open a new Warsaw office to target Poland’s fast-growing smart infrastructure market.

Bisly’s AI-powered, cloud-based platform uses patented digital twin technology to manage energy use and indoor environments, cutting automation costs by up to 50% versus legacy systems and offering CO₂ reductions up to six times cheaper than transport electrification. The system works with both new and existing buildings and integrates with third-party devices to avoid vendor lock-in.

The funding will also support the launch of a wireless retrofit product line, expand engineering and sales teams, and sustain the company’s triple-digit revenue growth trajectory into 2025. Learn more

Carbelim Raises Pre-Seed Funding

Indian climate-tech startup Carbelim, incubated at IIT Madras, has raised a pre-seed round from Campus Fund and angel investors to expand its algae-powered systems that convert CO₂ into oxygen and valuable plant-based products like vegan Omega-3.

Founded by Dr. Karthika Gopi, Rahul Babu, and Gopakumar G, Carbelim’s BioMimetic Facade and OmegaPod integrate modular algae-based photo-bioreactors into building exteriors and micro-farms, capturing pollutants, releasing oxygen, and producing biomass. Each square meter captures up to 52 kg of CO₂ and produces 28 kg of biomass annually, monitored via Carbelim’s AI dashboard.

The company has seven US patents filed, a $5.1M Letter of Intent from a German airport developer, and discussions underway with South American governments for algae-integrated infrastructure projects. Funding will accelerate R&D, AI optimization, global expansion, and extraction of high-value pigments for pharmaceuticals and cosmetics, creating multiple revenue streams from its sustainable technology.
