Boom reaches out to your customers before you lose them. We run proactive outbound conversations at scale: recovering churned users, re-engaging drop-offs, and protecting revenue you thought was gone. AI agents hold real conversations with your customers over SMS, email, WhatsApp, or phone, in their language, on the channel they actually answer. Every month, companies lose 5-15% of revenue to churn, and more walks out through abandoned signups and failed onboarding. The tools built to fix this don't work. Win-back emails get ignored. Cancel flows only catch people at the door. Hiring humans doesn't scale. Boom does the one thing that works: a real conversation. 1,000x the reach of manual outreach, and the customer can reply.

malibou is a web application helping French SMBs to manage employees, run payroll and track compliance in a single app. When processing payroll in France, you either have the choice between an accountant with good advice but no way to connect an HRIS with him, or a good HRIS that does not include payroll services. It was time for a change, to finally bring payroll and HR at the same place. Due to increasing competition in the space, French payroll engines have just opened their APIs. This allows us to offer a unified payroll and HR solution, which wasn't possible before.

Lovage helps barbers and stylists fill empty appointment slots and get more clients. Beauty professionals frequently have gaps in their schedules due to cancellations, no-shows, and uneven demand. Lovage turns that unused availability into booked appointments. We integrate with booking systems to detect open slots, generate on-brand content, and distribute it to channels like Instagram where clients can instantly book. The result is more bookings, higher utilization, and increased revenue without relying on ads or manual marketing.
