🧠 Inspiration

Sabl AI was born out of a real problem — I got my hands on a massive scraped dataset of business leads, but had no streamlined way to manage and reach out to them at scale. CRMs like Salesforce are powerful, but slow to act. Outreach tools are siloed. I needed something faster, something that could initiate conversations, not just store them. That’s when I realized: if sales is all about timing and context, why not have an AI do the heavy lifting the moment a lead lands?

🚀 What it does

Sabl AI automates the first touch with leads — combining Salesforce, Slack, and AI voice calling into one seamless workflow. With a single action in Salesforce, Sabl:

Places an AI-powered outbound voice call to the lead
Creates a dedicated Slack channel with real-time call transcription and summary
Gives the team a centralized space to collaborate, follow up, and convert

It transforms lead management from static records into live, ongoing conversations.

🛠️ How we built it

We used:

Salesforce Apex + Flows to define trigger logic and send lead data
Slack API to dynamically create channels and post updates
Vapi.ai to handle real-time voice calls and transcriptions
OpenAI for summarization and suggested next steps
A JWT-authenticated Node.js proxy server to glue everything together and securely handle logic between services

Everything is designed to be low-latency and scalable across thousands of leads.

🧱 Challenges we ran into

Getting Salesforce Flows and Apex to cleanly trigger external voice calls without timing out
Handling Slack event consistency with scheduled messages and channel creation
Managing auth flows across Salesforce, Slack, and Vapi while staying secure
Making the AI-generated voice sound human enough for a natural first impression

🏆 Accomplishments that we’re proud of

Seamlessly integrated three major platforms (Salesforce, Slack, Vapi) in a single workflow
Built a Slack-first experience for lead management that feels collaborative, not clunky
Enabled full AI voice call initiation directly from Salesforce — no third-party app jumping
Made it possible to run entire lead engagement flows without a human touch, until it matters

📚 What we learned

Slack can be an incredibly powerful UI layer for enterprise workflows when used creatively
Salesforce Flows + Apex are surprisingly flexible if you think modularly
Good outbound AI needs tight control over timing, tone, and context — it’s not just about GPT
