Not a platform. A partner.
A dedicated engineer who joins your team
When you partner with SIMBA, you don't get a login and a knowledge base article. You get a Forward Deployed Engineer — a real person who builds your voice agents, lives in your Slack, and iterates with you every single week.
Other platforms give you a dashboard and wish you luck. We embed with your team, learn your business, and own the outcome. Your FDE handles setup, tuning, monitoring, and expansion — so your voice agents keep getting better, not stale.
We set it up for you
Your FDE builds the agents, configures integrations, and trains the knowledge base — not your team.
We join your Slack
Need a tweak? Tag your engineer. No tickets, no wait times, no support queue.
We iterate constantly
Weekly reviews, prompt tuning, new use cases. Your agents get smarter every week because a human is actively improving them.
We own the outcome
Your FDE is measured on your results — resolution rates, call quality, ROI — not on closing a ticket.
What your FDE does — week by week
Onboards into your tools, builds V1 agents, goes live on a pilot use case.
Monitors every conversation, tunes prompts and flows, fixes edge cases in real time.
Weekly performance reviews, new use case rollouts, integration expansions, and continuous optimization.

Operations & Automation
Navigate any phone tree automatically
SIMBA agents don't just answer calls — they make them. With built-in IVR detection and navigation, your agents can call insurance companies, pharmacies, vendors, and government agencies, then navigate through their phone trees to reach the right department and complete the task.
This unlocks operations use cases that other voice AI platforms can't touch: automated insurance verification, prescription status checks, vendor follow-ups, claims submissions by phone, and any workflow where your team currently sits on hold pressing buttons.
Detects IVR systems automatically
SIMBA recognizes when it hits a phone tree — DTMF menus, speech-based IVR, or hybrid systems — and switches to navigation mode.
Presses buttons and speaks responses
Handles "press 1 for billing" and "say your account number" prompts, navigating multi-level menus to reach the right destination.
Completes the task end-to-end
Once connected, the agent handles the conversation — verifying insurance, checking claim status, confirming appointments, or collecting information.
Runs hundreds of calls in parallel
What takes your team 8 hours of hold time, SIMBA completes in minutes by running calls concurrently.

What is an AI voice agent?
An AI voice agent is a software system that uses artificial intelligence to have natural, human-like phone conversations. Unlike traditional IVR systems that force callers through rigid menu trees, AI voice agents understand natural language, respond in real-time, and take actions like booking appointments, looking up account information, or processing transactions — all through voice.
SIMBA Voice Agents by Speechify is an enterprise AI voice agent platform that enables businesses to deploy conversational AI agents for customer support, lead qualification, outbound sales, and reception. SIMBA agents operate across phone, web chat, WhatsApp, SMS, and email with sub-second latency in multiple languages.
How do AI voice agents differ from chatbots and IVR?
Traditional IVR systems use pre-recorded prompts and DTMF keypad input (“press 1 for billing”). Chatbots handle text-based interactions. AI voice agents combine the best of both: they understand spoken language, respond with natural-sounding speech, and take real actions in your business systems. The result is a phone experience that feels like talking to a knowledgeable human — available 24/7, in any language, at a fraction of the cost of a contact center.
What industries use AI voice agents?
AI voice agents are used across healthcare (patient scheduling, intake, follow-ups), insurance (quoting, claims, enrollment), financial services (loan servicing, collections, account support), home services (dispatch, appointment booking), hospitality (reservations, concierge), education (enrollment, tutoring support), and legal (intake, case status updates). Any business that handles phone calls at scale benefits from voice AI automation.
