A Helsinki-based healthtech startup founded by serial entrepreneurs has closed an oversubscribed €7.5 million seed funding round to scale its artificial intelligence operating system designed specifically for cancer care professionals.
Gosta Labs, founded by the former Kaiku Health founders, secured investment led by Voima Ventures, with participation from COR Group, Terveystalo, the Aho family, and both existing and new investors, including Reaktor and several angel investors. The round follows a €1.7 million pre-seed investment in 2024, bringing the company’s total funding to nearly €10 million.
The startup addresses mounting pressure on oncology departments worldwide. By 2050, more than 35 million new cancer cases are expected to be diagnosed across over 100 different types of cancer, whilst clinicians currently spend several hours daily on administrative work within fragmented systems.
Gosta Labs’ AI operating system transforms patient visits into structured data in real time, automatically summarising and visualising patient journeys whilst capturing clinical data relevant to care. The system also assesses key clinical parameters for each treatment pathway and links decisions to international guidelines, enabling faster and more consistent care delivery.
Proven Track Record
The company was established in 2023 by Lauri Sippola and Henri Viertolahti, who previously founded Kaiku Health. That venture was acquired by Swedish precision radiation medicine company Elekta in May 2020, demonstrating the founders’ ability to build and scale regulated digital health solutions.
Kaiku Health’s patient monitoring platform was being used in more than 40 European cancer clinics at the time of acquisition, helping patients track symptoms and enabling healthcare teams to respond quickly to reported issues.
Initial real-world results from the Gosta AI Operating System were presented at the ESMO 2025 Congress, a leading global oncology conference. The findings suggest the system generates high-quality oncology consultation notes in real time, structured according to institutional standards, whilst automatically classifying Performance Status and CTCAE toxicity grades.
Dr Razvan Popescu, Medical Director at Tumour Centre Aargau and lead investigator in the study, said the technology has already reshaped clinical workflows at his cancer centre. Oncologists were able to complete follow-up visit documentation in a median time of under two minutes, cutting documentation time by more than two-thirds for each patient visit.
International Expansion
Gosta Labs’ AI operating system is already in use with leading healthcare providers in Finland, Switzerland, the Baltics, and Australia. The company’s leadership team combines artificial intelligence scientists with experienced oncology and medtech leaders, including Chief Medical Officer Dr Lionel Hadjadjeba and Chief Operating Officer Reetta Arokoski, both of whom bring decades of experience scaling cancer-care technologies internationally.
Jussi Sainiemi, Partner at Voima Ventures, highlighted the team’s proven execution capabilities. Voima Ventures is a Helsinki-based deep tech venture capital firm that focuses on science-based companies tackling global challenges.
Lauri Sippola, CEO and Co-Founder of Gosta Labs, said: “We started Gosta Labs to bring AI to support extremely complex medical specialties like oncology, to give care teams back time and headspace for their patients by taking on the documentation work that drains their day. This funding helps us bring our trusted AI assistant to oncology teams around the world.”
The fresh capital will enable Gosta Labs to expand its medical device grade product internationally whilst deepening its AI foundation to ensure patient encounters are safer, more personalised, and less burdened by administration.
