Alta

Alta describes itself as an AI GTM system of actions. Its AI SDR agent, Katie, handles outbound prospecting and outreach, and Alta also offers an AI calling agent, so teams can combine email and phone in one AI-driven motion.

Katie researches prospects, writes personalized outreach and follows up, working from your targeting and messaging. Alta is listed on Salesforce AgentExchange, and it includes white-glove onboarding to set up the agents around your process. The company raised a $25 million Series A in July 2026, so it is still building its track record, but it is growing quickly in the AI SDR space.

Alta suits B2B sales teams that want an AI SDR plus AI calling with hands-on setup support, particularly those already using Salesforce.

Pricing is custom and usage based, described as paying for what you use and scaling with your team, and quotes are gated behind a contact form. Before buying, ask exactly what is metered, such as contacts enriched, messages sent, calls placed or meetings booked, and whether there is a minimum commitment.
