When to choose Hyperbound vs Sellible (and when to walk away)
Choose Hyperbound if

Walk away from Hyperbound if
- Walk away if you require transparent self-serve monthly billing or your budget ceiling is under $1,000/mo (Hyperbound requires sales-gated custom quoting).
- Walk away if your workflow cannot tolerate acoustic latency overhead: Network jitter and round-trip audio inference delays can occasionally introduce micro-pauses that break human conversational cadence during rapid verbal exchanges.
- Walk away if persona context boundary drift is a deal-breaker for your team: When reps introduce non-standard technical edge cases outside ingested collateral, synthetic buyers can hallucinate organizational priorities or concede points prematurely.
