About this formation
What began as software that assists salespeople is splitting into software that replaces entire slices of the sales function outright, and the vertical-specific bets are where the real specialization shows up. Avoca, ShortLoop, SpadeWorks, and Twine all target a narrow, unglamorous problem, the missed phone call, but they've each picked a different vertical, service businesses, dealerships, trade contractors, to own end to end rather than building one horizontal dialer. Meanwhile Paragon AI, Fabius, and Hindsight represent the older instinct of the category: sit alongside human reps and turn calls into CRM data or coaching insight rather than take the call yourself. That split matters because this formation is growing at 7.50x, nearly double the 3.91x rate of Sales Enablement and well ahead of Customer Success at 4.76x, meaning the fastest growth is concentrated in the agents doing the selling, not the tools helping humans sell better. This timing tracks closely with voice AI reaching commercial-grade latency and reliability only around 2023, which is exactly when Avoca, ShortLoop, Persana AI, and Yuma AI all emerged, suggesting the phone call itself only recently became automatable rather than merely analyzable. The result is a category quietly redefining what "sales software" even means, from a system of record into a system of action.
