Bolt is the first opportunity in the Crowdcube Growth Series - an exclusive selection of lower-risk, later-stage primary and secondary opportunities that are typically reserved for institutions and family offices.

For decades, cities have been designed for cars, often neglecting pedestrians, cyclists, and public transport. Bolt is reversing that trend by reducing private car use, cutting emissions, and improving connectivity through shared mobility.

What is Bolt market potential?

The global shared mobility market is forecast to reach a Total Addressable Market of €376 billion by 2030, with the potential to provide flexible income to 16 million people worldwide.

metr on Invesdor

New technology for energy-efficient buildings

Industry - Proptech / AI

Valuation (pre-money) - 15,000,000.00 EUR

Company and product stage - The system fulfils international regulations and has already been contracted by almost 70 leading property and industrial companies for 3,600 buildings with more than 100,000 rental units in total.

What problem metr is solving?

The challenge:

Due to growing regulations, rising interest rates and increasing energy prices, landlords struggle to profitably manage real estate. Indeed, the real estate sector accounts for around 40% of all energy consumption in the EU, whereby 80% of the energy is used in the operating phase of buildings for heating & cooling. At the same time, most buildings are “low-tech” and still not energy-efficient. This leads to high energy bills, putting increasing financial pressure on tenants. Moreover, high interest rates, stricter regulations and increasing pressure to comply with environmental regulations and costly renovations reduce real estate yields for landlords.

metr’s solution:

By combining AI-powered software with an easy-to-install multi-functional gateway (m-gate) that reads out all kind of controllers of heating systems and connects them to the cloud, metr brings transparency and control to energy consumption. The platform detects inefficiencies across all kinds of heating manufacturers, recommends actions, and automates key processes like heating optimization and hydraulic balancing.

What is metr market potential?

Based on metr’s market assessment, the total addressable market for building energy efficiency and transparency in Europe is estimated at more than €110 billion annually, including:

~€87 billion in energy efficiency services

~€31 billion in energy transparency and data solutions

Augmented Robotics on Fundernation

AI that understands its environment – ​​efficient training of spatial AI with Horus AI

Estimated return of 263% 

Industry -  AI in robotics

Raising - 800.000 EUR

Valuation (pre-money) - 3.000.000 EUR 

Company and product stage - Two international patents granted—one for dynamic object recognition via smartphone in physical spaces (core to Horus AI), and another for integrating toys with smartphones used in AR Battle Core.

What problem Augmented Robotics  is solving?

Problem: Most machines—including robots and AR/VR systems—can capture visual input but lack a true understanding of their 3D spatial environment. Training such “Spatial AI” typically requires expensive hardware and expert knowledge, making it inaccessible at scale.

Solution: Augmented Robotics offers Horus AI, a patented platform that dramatically simplifies and democratizes Spatial AI training. Users only need to upload a short smartphone video of an object—no special equipment or expertise required—and the platform automatically generates a high-quality 3D recognition model. This process is at least 10× cheaper than traditional methods and works on standard smartphones.

What is H2 POWER N HEAT  market potential?

The Spatial AI market—covering domains like robotics, AR/VR, autonomous systems, and smart cities—is projected to grow at around 20% CAGR, and exceeded USD 100 billion globally in 2022.

Augmented Robotics is initially focused on the entertainment and toy sector, leveraging its scalable solution to digitize a largely analog industry. Through its DACH-region exclusive partnership with Simba Dickie, a major European toy company, it has already secured a significant distribution channel.

Beyond toys, Horus AI holds promise for software developers, CV specialists, and creators in 3D model training—opening doors to B2B use cases that tap into broader Spatial AI solutions across industries.

Medhunter on CrowdFundMe

Digital platform that revolutionizes recruitment in the private healthcare sector, connecting healthcare professionals with healthcare facilities in a direct, confidential and targeted way

Industry - HealthTech

Raising - 100.000 EUR

Valuation (pre-money) - 1,750,000 EUR 

Company and product stage -  Over 3,300 registered professionals (+73% quarterly growth)

What problem Medhunter  is solving?

Problem:

Medhunter addresses a long-standing inefficiency in the Italian private healthcare market: the difficulty in matching qualified healthcare professionals with private healthcare facilities. This is especially critical amid a chronic shortage of personnel and rising demand from the private sector 

Solution:

Medhunter offers a vertical digital platform tailored to healthcare recruitment—facilitating a direct, confidential, and efficient matching process. Utilizing a "reverse recruiting" model, professionals can anonymously explore job opportunities, while healthcare structures can view anonymized profiles and pay only (€25–€35) when they choose to unlock a professional’s identity, enabling a pay-per-lead model that bypasses intermediaries and cuts cost and friction

What is Medhunter  market potential?

The Italian private healthcare sector is substantial—valued at approximately €70 billion, with an expected growth rate of up to 8% annually. This shift has been fueled in part by professionals leaving the public sector for better opportunities in private care 

Medhunter's focus on a vertical, niche-focused marketplace gives it a scalable edge. The model demonstrates increasing effectiveness as more users join—thanks to network effects—and there is currently no dominant player in Italy’s private healthcare recruitment space
