Honest comparison
Sealio, Gong or Modjo: they don't do the same job.
Gong and Modjo are revenue intelligence tools. They record, transcribe and analyze calls so managers can coach after the fact. Sealio is a closing copilot: it works during the call, while the prospect is still on the line. It is not a better Gong — it is a different job.

When to pick which
Sealio is for the salesperson who closes live. The objection is detected in real time, a cue or script from your product sheet appears, and you rephrase it while the prospect is still there.
Gong
Gong fits teams that want a coaching and analysis platform after calls — especially on an English-speaking market, with managers who listen back afterwards.
Modjo
Modjo does the same job as Gong, closer to French-speaking teams. If your priority is reviewing calls, scoring conversations and coaching the team, that is the right aisle.

Common questions
- Is Sealio a Gong alternative?
- Not as a replacement. Gong analyzes calls afterwards for managers. Sealio feeds you an answer during the call, from your product sheet. If you want after-call coaching, Gong (or Modjo) is still the right tool. If you want a live rundown, this is a different purchase.
- What about Modjo?
- Modjo is a revenue intelligence platform built for French-speaking teams. Sealio does not try to do that job better: it does not record for the manager, it assists the closer during the conversation.
- Can I use Sealio with Gong or Modjo?
- Yes. A copilot during the call and an analysis platform after the call complement each other. Sealio does not replace a revenue intelligence tool, and the reverse is not true either.
- Does Sealio analyze calls after the fact?
- It produces a structured debrief from the live transcript — points covered, objections, commitments. That is not the core of the product. The job is having the right answer while the prospect is still on the line.
