Founded in 1994 by Sean O’Sullivan, SOSV — The Accelerator VC — operates eight accelerator programs around the world:

SOSV invests in over 150 companies per year and over its two-decade history has a net realized IRR of over 30%, putting it in the top 5% of private equity managers in the world. The team at SOSV dedicates approximately 20% of our own time promoting big ideas for positive global change, from organizations and movements that focus on STEM (Science, Technology, Engineering, Math) education to environmental causes such as global warming.


RebelBio is an Innovation Engine to build the future with biology.

We invest in innovative biotechnology startups and help them solve global grand challenges through scientific innovation. We’re the leading early-stage  accelerator in life sciences and part of SOSV, the accelerator VC.


We accelerate early-stage startups to the seed stage. We de-risk and accelerate biotechnology and build lean, profitable businesses in a revenue-focused programme, while empowering the founding team to make their vision a reality.

Our accelerator helps life sciences innovators, academics, biomakers and citizen scientists to change the world with biology. We provides early-stage funding, fully-equipped lab space, a ‘startup 101’ business training and mentorship to drive this transition in a fast-paced, intense 4 months programme. The first months offers hands-on business training to refine the business plan and strategy, then it kicks-off with three months in the lab. Each week, the teams receive intensive mentoring and training, as well as networking opportunities and pitch events throughout the programme. The accelerator culminates in a demoday showcase and we keep supporting the teams afterwards.

Can you grow a moonshot in a petridish? Our process makes it possible.






You will receive investment of $100,000 for just 8% equity in your biotech startup and you will have a world leading VC on your cap table to assist in getting follow on investment, . This investment comprises of $50,000 in cash, which can be spent on the company as you see fit  and $50,000 in programme costs which will cover all the awesome resources provided by RebelBio over the course of the programme. These resources include BSL-2 Facility, access to world class mentorship and the potential access to follow on investment via RebelBio exposure and events.

Post program companies can access a further 25k at an uncapped valuation if they meet the criteria for follow on.


RebelBio operates in a fully-equipped BSL-2 lab in University College Cork, a prestigious National University of Ireland specialising in microbiology, microbiomics and molecular biology. The RebelBio Lab includes all necessary pieces of lab equipment needed for routine microbiology and chemistry, with access to more advanced equipment in UCC, the UCC SynBioCentre and the prestigious Tyndall Institute by request and arrangement.


You’ll be mentored by a global group of the most talented, successful and provocative minds in Science and Business. Our mentors list is constantly growing, and will support you from bench to market.

After the program ends, you’ll pitch to potential investors and allies including your hosts, SOSV, for follow on funding. Training in communications, marketing and pitching is given throughout the programme with regular opportunities to develop this crucial skill in representative setting; be as ready as you can be!

Connections to other alumni companies may open unique collaborations, mind-share, or simply a social outlet for like minds.
