The Opportunity Dealstack is a SaaS platform that powers private equity. Deal making in PE remains manual, chaotic and backward, and our goal is to end these outdated practices and become the new collaboration standard in the industry. Built by PE, for PE, our solution sits at the intersection of SaaS, fintech and legaltech. Our first product went live in 2023 and we have launched several more since, creating a multi-use case operating system for private equity.

Following strong commercial traction from leading industry players, we are building out our Client Success function in Bulgaria. We are looking for a proactive, detail-oriented individual to support our clients across their day-to-day use of Dealstack and to help deliver the onboarding of new investment programmes onto the platform. You will be at the frontline of client interaction, supporting investment professionals, lawyers and portfolio company teams, while also working behind the scenes to get their schemes set up correctly and on time. It is a broad role with real ownership from day one and plenty of room to grow as we expand the team in Bulgaria.

About Us Dealstack is on a mission to power private equity Dealstack was founded by experienced private equity practitioners with the goal of ending the outdated deal administration practices that have plagued the industry since its inception. Manual and repetitive, these practices remain very time-consuming, costly, and error prone. We know how frustrating they can be. Yet, while we cannot remove the need for these tasks to be completed, we can equip professionals with better tools.

The design of Dealstack is fully focused on helping our old selves work faster, smoother and feel better. By engineering away the burden of deal administration, we can give way to what matters most, creating value. We want Dealstack to become a central part of the dealmaking toolkit – just as obvious as Word, Excel or PowerPoint might feel today – only 100x better!

We recognise that changing old habits can be difficult. Our aim is not to change what works and take away that precious feeling of control. We want to enhance, not replace. Evolve, not revolutionise. We know that peace of mind is central to our users. To that end, we have built Dealstack with best-in-class security, service, and user experience as our core guiding principles.
