The problem

B2B sales teams run outreach across three disconnected silos: a mailbox, a LinkedIn account, and a phone. Each silo has its own tool, its own sequencing logic, and zero awareness of what the others are doing. Reps end up double-touching the same prospect on two channels in the same day, miss the right moment on the third, and waste hours stitching together a picture of who has been contacted, where, and what they said back.

What I built

A multichannel outreach platform that collapses Gmail, LinkedIn and WhatsApp into a single coordinated flow — one prospect, one journey, three channels.

• A multi-tenant Supabase backend with row-level security, so each workspace stays fully isolated.
• A queue-based engine that orchestrates outreach across the three channels, with per-channel rate limits and quiet hours to keep accounts safe.
• Stripe billing wired into Supabase auth — full self-serve signup, plans and upgrades, no manual intervention.
• A Unipile integration so a single user can run multiple accounts per channel in parallel.
• The full marketing site and product dashboard, designed and shipped on Vercel.

Calyxo is the proof that Oxelis does not stop at advice — the same playbook (research the problem, build the working system, measure that it moves the number) gets shipped end-to-end, only this time the client is me.

The result

In private beta, with the full multichannel engine in production and the first cohort of users onboarded. Public launch in 2026.
