The pre-seed round was led by Vicus Ventures and CIV to support expansion within enterprise certification markets.

The funding round was led by Enlightened Hospitality Investments and accompanies a global partnership with Shake Shack.
"I have always believed that Enlightened Hospitality – the ethos that when you take care of your people, your people take care of your customers – is how to create sustaining success in any business"
The pre-Series A round was led by VERBUND X Ventures with backing from Octopus Ventures, Armajaro Holdings, and Green Angel Ventures.
"Efficient use of cloud and AI is possible when the right culture and tooling is embraced. With Greenpixie’s high fidelity sustainability data enterprises can maximise the full potential of their intelligence. This funding will enable us to accelerate our mission and continue our global reach in these pivotal times."
Headline led the Series A investment to help the company accelerate product development and expand its international presence.
"AI‑driven discovery is rewriting how customers find products, and the economics are moving fast. As more searches are answered directly by AI, brands that are invisible in this layer of search will simply see less demand. The companies that adapt first will protect and grow market share; those that don’t will lose it quietly. We backed Semrush early as the category leader and exited following its IPO at around a $2B market cap. Now, we see a new generation of businesses coming up and Searchable is primed to win this market, which is why we are ecstatic to lead the current round."
The oversubscribed funding round was led by SFC Capital to support clinical expansion and regulatory progress for the firm's memory testing platform.
"Many new therapies for Alzheimer’s disease and related conditions are designed to work at the earliest stages of the disease process. However, most existing cognitive tests detect impairment only once irreversible damage has already occurred. Our test shifts the detection window years earlier, providing a far more sensitive way of identifying subtle changes in memory."
