Builds a real-time AI assistant for sales teams that joins live calls, synthesizes organizational knowledge from CRMs, ERPs, docs, and Slack, and surfaces technical answers, objection handling, and automated notes.
Real-time AI call support, automated note-taking to Slack and CRM, continuous learning from every call, deep integrations with organizational knowledge sources. Making every rep perform like the team's top technical closer.
Investment in RAG pipelines for real-time audio processing. Multi-modal AI capabilities (voice + text). Expansion into post-call analytics and coaching. Deeper CRM/ERP integrations likely. Move toward predictive deal intelligence.
<p>Real-time AI assistant that joins live sales calls to surface technical answers, handle objections, and provide product knowledge instantly.</p>
It's like having your company's best product expert whispering the perfect answer in every sales rep's ear during every call.
Caretta's core use case is a real-time AI assistant that joins live sales calls and listens to the conversation as it unfolds. When a prospect asks a complex technical question or raises an objection, the AI instantly retrieves and synthesizes relevant information from the organization's knowledge base—including CRM records, product documentation, engineering specs, Slack threads, and prior call transcripts—and surfaces a concise, accurate response for the sales rep. This eliminates the need for reps to say "let me get back to you," dramatically shortening sales cycles and increasing close rates. The system uses advanced NLP and retrieval-augmented generation to understand conversational context, match queries to the most relevant knowledge fragments, and present answers in a format optimized for real-time verbal delivery. Over time, the AI learns from every interaction, expanding its objection library and improving response accuracy across the entire sales organization.
It's like having a Google search engine that already knows your entire product catalog and whispers the top result into your earpiece before the customer finishes their question.
<p>Automated post-call note generation and CRM/Slack synchronization that eliminates manual data entry for sales reps.</p>
The AI listens to your sales calls and automatically writes up perfect notes and pushes them to your CRM and Slack so reps never have to.
After every sales call, Caretta automatically generates structured, high-quality notes summarizing key discussion points, action items, objections raised, competitor mentions, pricing discussions, and next steps. These notes are instantly pushed to the team's CRM (e.g., Salesforce, HubSpot) and relevant Slack channels, ensuring that deal records are always complete and up-to-date without any manual effort from the sales rep. This solves one of the most persistent problems in sales operations: incomplete or inaccurate CRM data caused by reps who are too busy selling to log notes. The system uses NLP-based extractive and abstractive summarization to distill hour-long conversations into concise, structured records. It identifies and tags key entities (contacts, products, competitors, dollar amounts, dates) and maps them to the correct CRM fields. Sales managers gain full visibility into pipeline health, and reps reclaim hours each week previously spent on administrative busywork.
It's like having a meticulous executive assistant who sits in every meeting, takes flawless notes, and files everything in exactly the right folder before you even hang up.
<p>Continuous AI learning system that absorbs knowledge from every sales call to build and expand the organization's collective sales intelligence.</p>
The AI gets smarter after every single sales call, learning new objections, product details, and winning talk tracks so the whole team benefits.
Caretta's continuous learning engine treats every sales call as a training opportunity. As reps interact with prospects, the AI identifies new objections, novel technical questions, competitive intelligence, updated pricing discussions, and successful talk tracks that are not yet captured in the existing knowledge base. These insights are automatically flagged, validated, and incorporated into the organizational knowledge graph, making the AI progressively smarter over time. This means that when one rep encounters a new competitor objection and handles it successfully, that knowledge becomes available to every other rep on the next call. The system uses techniques from active learning and knowledge graph construction to continuously expand its coverage without requiring manual curation. Sales leaders can review and approve suggested knowledge additions, ensuring quality control. Over time, this creates a powerful flywheel effect: more calls lead to more knowledge, which leads to better real-time support, which leads to more successful calls—compounding the organization's collective sales intelligence.
It's like if every time one person on your team learned a new trick, the entire team instantly knew it too—like a hive mind for your sales floor.
<p>Slack-native AI assistant that provides daily team briefings, answers ad-hoc product questions, and supports asynchronous sales enablement.</p>
A smart Slack bot that knows everything about your product and deals, so reps get instant answers without bugging the product team.
Caretta extends its AI capabilities beyond live calls into the team's daily Slack workflow. The Slack-based assistant provides automated daily briefings summarizing upcoming calls, deal status changes, and key insights from recent conversations. Reps can also ask the AI ad-hoc questions at any time—about product features, pricing rules, competitive positioning, or customer history—and receive instant, contextually accurate answers drawn from the full organizational knowledge base. This dramatically reduces the volume of internal escalation tickets to product, engineering, and sales enablement teams, and ensures that reps always have access to the latest information regardless of time zone or availability of subject matter experts. The assistant uses conversational AI and retrieval-augmented generation to understand natural language queries in Slack, retrieve the most relevant knowledge fragments, and deliver concise answers formatted for quick consumption. It also proactively surfaces relevant information based on upcoming meeting context, ensuring reps are always prepared.
It's like having a brilliant colleague who never sleeps, never gets annoyed by repeat questions, and always has the perfect answer ready in your team chat.
Natively built for the hardest sales conversations, complex technical products, where generic AI assistants fail. Real-time knowledge synthesis improves with every call across the entire sales org. Backed by YC and a16z at pre-seed/seed stage.
