Background
Ossus, formerly Librar Labs, is a YC-backed library software company. It hired Hyperke to build and run outbound as a customer acquisition channel for the education market.
The Problem
Ossus, formerly Librar Labs, was a YC-backed library software company with three weeks before Demo Day. The founders wanted to reach 500 schools by the end of the batch and were planning outreach at more than 500,000 emails per month. They lacked experience running cold email at that volume and could not risk their main domain.
The team also needed an audience that standard databases barely covered: school librarians, principals and IT decision-makers. Buying another contact list or increasing send limits would leave those constraints unresolved.
What We Did
We built a list of approximately 30,000 verified contacts using school directories, staff websites and accumulated reply data from earlier outreach. Names, roles and school domains helped us identify relevant decision-makers and validate email patterns. Our existing campaign data supported contact discovery in a market poorly covered by standard databases.
We provided dedicated sending capacity across more than 180 domains and launched five messaging variants. Every 48 hours, we used response data to stop weaker variants and expand the ones producing interest. This connected audience discovery, delivery infrastructure and campaign learning in one managed process.
When bookings exceeded the team's call capacity, the client's engineers built a direct signup route. We adapted the outreach so interested schools could create an account without waiting for a demo, while Hyperke continued handling meeting coordination and follow-up.
The Results
The initial sprint generated 108 combined demos and signups in 14 days. In his later account of the engagement, Eren reported more than 300 meetings and an attendance rate above 80%. These describe different reporting points and should not be added together.
Ossus gained access to school decision-makers, a managed outbound operation and a way to capture demand when its sales calendar filled. The work supported the company's need to build customer traction quickly while the founders continued developing the business.
With you guys, you did some magic actually. We had a show up rate over 80%.
