In their own words, as submitted to SaaSHub.

Resonis
Diffee

Your sessions matter. So do the 167 hours in between. Resonis gives your coaching clients a private space to check in between sessions, whenever something's on their mind. It listens and reflects back in their own words, usually with one gentle question. It never gives advice and never coaches....

Questions & Answers

As answered by people managing Resonis and Diffee.

What makes your product unique?

Resonis's answer

Resonis gives the coach a written brief before every session, built from what the client shared in the days between. Most coaching tools collect something from clients, like tasks, habits or ratings. Resonis is the one that hands you the read: what's happened, the themes, the mood, the wins, and what your client wants to explore. And it never coaches. It listens and reflects, then hands everything back to you.

Why should a person choose your product over its competitors?

Resonis's answer

If you already have tools for booking and payments, Resonis does the one job they don't: the 167 hours between sessions. There's no homework to set and no activities to build, and clients join free with nothing to download. You get a short brief before every session, see when a client has gone quiet, and every message is screened for signs of risk. One flat price for up to 25 clients, with no commission on what you earn.

How would you describe the primary audience of your product?

Resonis's answer

Independent coaches who work one to one with the same clients over several sessions: life, mindset, career, wellness, leadership and business coaches. Especially coaches who want to stay connected to clients between sessions without being on call by WhatsApp.

What's the story behind your product?

Resonis's answer

I'm Michael, a certified REBT mindset coach. When I was coaching, I'd ask a client how things had been and get a fraction of the story. The moments that really mattered had happened days earlier. After a cancer diagnosis I stepped back from coaching, and during treatment I started building the tool I'd always wanted: something that holds those moments without getting in the way of the coaching. Resonis does exactly that, and nothing more.

Which are the primary technologies used for building your product?

Resonis's answer

  • Anthropic Claude (AI)
  • Python
  • Supabase (EU-hosted database)
  • Railway
  • Stripe
  • Cloudflare
