Your Team Has AI Tools. Your Team Still Does All the Work.
AI assistants generate suggestions. Someone still has to implement them.
Your team uses 6+ disconnected tools — nothing shares context
ChatGPT and Jasper generate drafts — someone still copy-pastes them into 5 more apps
Sintra AI creates content — it has no API, no execution layer, no shared workspace
Your RevOps stack has no AI execution layer — just AI suggestion tools
Every new AI tool = another onboarding, another vendor, another invoice
You're paying for headcount to implement what AI should be doing automatically
SynthAI Executes. Your Team Approves.
Autonomous Campaign Execution
Brief the AI once. Watch it build the campaign, generate creatives, launch on Meta/Google, and report back — without anyone touching another tool.
Replaces 1–2 marketing FTEs at $60–120K/year
API-First Architecture
Connect SynthAI to your CRM, marketing stack, and data warehouse. Build automations that trigger campaigns from CRM events. Sintra has no API. This is what sets us apart.
HubSpot · Salesforce · Zapier · Make · custom stacks
Proactive Intelligence
Your AI operations layer monitors performance and pushes recommendations to your team every morning — without anyone writing a prompt. Every team member sees what to work on. Nothing falls through the cracks.
Replaces weekly analytics reviews and campaign status meetings
Workflows that ship — not chats that draft.
Three of the workflows our B2B customers fire on day one.
Sales sequence + CRM logging
SynthAI drafts the outbound email, sends from your domain, logs the activity in HubSpot, and books the reply on your calendar.
Daily campaign optimizer
Each morning, Basis reviews ad and email performance, pauses losers, scales winners, and posts the summary to your team Slack.
Lead enrichment + routing
New form-fill comes in → Lumen enriches the lead, scores it against your ICP, writes the first-touch email, and routes to the right rep.
Built for these teams
Not everyone is a fit. These three are.
B2B SaaS · 11–200 employees
RevOps/Marketing Ops teams stitching together HubSpot, Outreach, Apollo, ChatGPT, and Notion. SynthAI replaces the glue.
DTC eCommerce · $1M–$50M ARR
Brands running Meta + Klaviyo + Shopify + a freelance designer. SynthAI ships ads, emails, and creative end-to-end.
Marketing agencies · 5–25 brands
Replace a 3-tool stack per client with one SynthAI workspace, white-label reports, and one bill.
