## 21X (formerly Structurely)

21X, previously known as Structurely, is a conversational AI platform for automating the conversations that drive revenue and customer experience. It covers inbound and outbound voice, two-way SMS, RCS, email and chat from a single agent builder, so a mortgage lender, real estate team or home services company can qualify leads, answer routine questions and keep every follow-up moving without expanding a call centre.

The platform is organised around a four-step flow: connect the tooling that captures inbound calls and maximises outbound contact rates; converse with fine-tuned AI that sells, overcomes objections, follows up and handles requests; take action by booking appointments, scheduling callbacks, transferring calls and extracting insights; and sync everything back by dispositioning conversations and updating your CRM automatically. Because actions and dispositions flow into existing systems, AI-handled conversations appear in the same pipelines your team already reports on.

Commercial terms combine a platform fee with usage-based metering in tokens, so cost scales with actual activity rather than idle seat licences. Voice usage runs as low as $0.07 per minute with your own carrier (BYOC), SMS as low as $0.02 per message and AI email as low as $0.02 per email. Three tiers are offered — Small Team, Large Team and Enterprise/Build Your Own — with the top tier adding custom SLAs, isolated infrastructure, SSO/SAML, white-label or headless deployment and dedicated AI engineering support. The company is headquartered in Aspen, Colorado.

**Pricing & Plans:** Platform fee plus usage-based pricing. No seat licences; you pay for the platform and for activity metered in tokens. Voice from about $0.07 per minute (BYOC), SMS from about $0.02 per message, AI email from about $0.02 per email, with volume discounts on higher tiers. Three plans — Small Team, Large Team and Enterprise / Build Your Own — are quoted via sales; a demo AI call is offered before you commit.

- **Inbound and outbound AI voice:** AI agents handle inbound calls and run proactive outbound campaigns across voice, SMS, email and chat, 24/7, without adding headcount.
- **Multi-channel conversation routing:** Agents qualify, answer, transfer, schedule, escalate and route each conversation based on intent, context and your business rules.
- **Action taking, not just talking:** Book appointments, schedule callbacks, execute live transfers to human reps, trigger workflows and capture documents and signatures automatically.
- **Automatic dispositions and CRM sync:** Conversations are dispositioned automatically, CRM records are updated, and customer data syncs back into your existing tools and workflows.
- **AI Power Dialer for Salesforce:** Launch AI and human dialing campaigns directly from Salesforce with call screening, live transfers and performance reporting.
- **Agent builder with industry templates:** Build agents with prebuilt industry templates for mortgage, real estate, life insurance, home services, private aviation and more.

**Strengths:** Handles voice, SMS, RCS, email and chat in one platform rather than separate point tools; Automatic dispositions and CRM sync keep AI conversations inside existing reporting; No per-seat licensing; cost tracks actual conversation volume; Prebuilt industry agents for mortgage, real estate, insurance, home services and more

**Limitations:** Platform fee is not published, so you must talk to sales to model total cost; Usage is metered in tokens, making spend harder to forecast than flat per-seat pricing; Initial setup of agents, telephony, A2P registration and workflows requires onboarding effort; Advanced capabilities like SSO/SAML, dedicated infrastructure and white labeling are Enterprise-only

## Zappx

Zappx is built by salespeople for salespeople, and it shows in the feature set. The core idea is parallel power dialing: instead of working a list one number at a time, Zappx dials up to five prospects at once and connects you to the first person who hangs up, so your team spends more of its day in live conversations and less waiting for a ring.

Around that core sit the mechanics that make cold calling less painful. Wrong numbers are filtered out automatically, voicemails can be dropped without any manual effort, and local presence rotates area codes to match the location of the prospect you are calling, which helps pickup rates and reduces the chance your calls get flagged as spam.

The AI layer handles what happens after the call connects. Automated transcription, sentiment analysis and call summaries give reps and managers a clear picture of each conversation, while realtime analytics add instant feedback, live leaderboards and the ability to compare past data against current performance. A testimonial from Closify's Alex Heiden reports making 50% more dials per day than with any other dialer. Pricing is not published, so you book a demo to see it in action.

**Pricing & Plans:** Contact for pricing. No public price list is advertised; the path in is booking a demo with the sales team.

- **Parallel power dialing:** Dial up to five prospects simultaneously and route the reps to the first person who picks up, so time is spent on conversations rather than ringing.
- **Filtering and voicemail automation:** Wrong numbers are filtered out automatically and voicemails can be left without manual effort, keeping your queue moving.
- **Local presence:** Area codes rotate to match the prospect's location, which helps improve pickup rates and keeps calls from looking spammy.
- **AI call intelligence:** Automated call transcription, sentiment analysis and call summaries let reps and managers review what actually happened on the call.
- **Realtime analytics:** Instant feedback, live leaderboards for friendly competition and historical performance comparisons keep the team focused.

**Strengths:** Dials up to five prospects in parallel to maximise connection rate; Filters wrong numbers and automates voicemails to keep the queue moving; Local presence rotates area codes to improve pickup and avoid spam flags; AI transcription, sentiment analysis and call summaries built in

**Limitations:** No public pricing; you must book a demo to get numbers; Parallel dialing to 5 lines can be inefficient or costly if your lead list quality is poor; No free plan advertised, so testing requires talking to sales
