AI agents & chatbots for SaaS companies
Automated customer support, onboarding, and expansion for SaaS products. 80%+ ticket deflection, RAG-grounded on your docs, integrated with Intercom, Zendesk, and your CRM — not another "we'll get back to you" bot.
Support costs scale with ARR. Until they don't have to.
SaaS companies hit a wall at the 1st-line support ratio. Docs exist but customers won't find them. Help-desk agents answer the same 200 questions 10,000 times, burning senior time on tickets that could have been deflected in a sentence. The economics of "hire another tier-1" start to break around Series B, and the queue keeps growing.
"We've added AI to our support" often means a worse version of the docs search — a chatbot that pattern-matches on keywords and sends users in circles. It doesn't read the changelog, doesn't know the customer's plan, can't reset a password or add a seat, and can't tell you when it's about to hallucinate.
The real answer is a RAG chatbot grounded on actual docs plus an agent that can take actions — reset a password, upgrade a seat, issue a credit — with human approval where it matters. Cited answers, confidence-threshold escalation, and full context handed to the human when it's time for a human. That's what caps headcount without breaking your CSAT.
Three SaaS agent patterns we ship in production.
Metrics below are ranges from live deployments across B2B SaaS customers.
Tier-1 support agent with RAG
RAG chatbot grounded on your help center, past tickets, changelog, and product docs. Handles password resets, billing questions, feature lookups, and integration troubleshooting. Escalates with full context to the human team for anything it isn't sure about.
Customer onboarding agent
In-app agent that walks new users through their first-value milestone. Monitors events from your analytics stack (Segment, Amplitude, PostHog), proactively nudges when a user stalls, and hands off to CS when a high-ACV account needs a human touch.
Expansion & churn-signal agent
Agent that monitors usage patterns for expansion signals (hitting plan limits, new team members invited, feature activation) and churn risks (login drop, support-ticket spike). Drafts expansion emails for your AE, flags at-risk accounts for CS.
Multi-tenant chatbot infrastructure for vertical SaaS.
White-label multi-tenant chatbot infrastructure for a vertical SaaS.
The platform served 200+ end-clients, each with their own knowledge base. We built a multi-tenant RAG chatbot infrastructure — shared orchestration, per-tenant vector stores, usage billing, per-tenant analytics, and white-label branding. Tenants self-serve via an admin UI; we handle the core infra.
The stack we deploy behind SaaS support and growth agents.
Native integrations with the help-desk and CRM you already use. RAG tuned for help-center scale. Observability per tenant.
Intercom · Zendesk · Help Scout · Front
Native integrations with webhook-driven handoff. Conversation context transferred, not re-asked.
HubSpot · Salesforce · Pipedrive
Agent reads account context (plan, renewal date, usage), writes back conversation summaries, flags at-risk accounts.
Pinecone · Qdrant · pgvector
Vector stores tuned for help-center and product-doc scale. Incremental re-index on doc publishes.
GPT-4o · Claude 3.5 · GPT-4o-mini
Claude for multi-turn reasoning; GPT-4o-mini for high-volume tier-1 deflection where cost matters.
Segment · Amplitude · PostHog · Mixpanel
Event-driven triggers for onboarding nudges and churn signals.
LangSmith · Helicone · custom dashboards
Per-tenant analytics, hallucination rate monitoring, cost tracking.
Multi-tenant & data isolation.
Four questions every SaaS team should ask before shipping a chatbot to end-customers. Here are ours, answered honestly.
How is tenant data isolated?
Per-tenant vector stores with strict access controls; separate retrieval scope per session; no cross-tenant leakage even with shared LLM API keys.
SOC 2 / ISO / GDPR?
We deploy on SOC 2-compliant infra; GDPR DPAs standard; EU-residency deployment option. We're not SOC 2 Type 2 as an entity — we deploy into your compliance posture.
Can we self-host?
Yes. Self-hosted stacks on Llama 3.3 or Mistral are standard for customers who can't send user content to OpenAI/Anthropic APIs.
Does it cite sources?
Yes — every answer cites the doc section it pulled from, and you can configure a confidence threshold below which the agent escalates instead of answering.
From tier-1 chatbot to multi-tenant platform.
Fixed project pricing. Per-conversation unit economics modeled in the discovery workshop so you know the monthly run-rate before you sign.
| Deployment | Scope | Price |
|---|---|---|
| Tier-1 support chatbot | RAG on help center, single help-desk integration, basic analytics | $8,000–$16,000 |
| Full support + CRM agent | Help desk + CRM writeback + action-taking (password reset, seat change) | $15,000–$30,000 |
| Onboarding + expansion agent | Event-driven in-app agent, analytics stack integration, CS handoff | $14,000–$28,000 |
| Multi-tenant chatbot platform | White-label, per-tenant isolation, usage billing, admin UI | $30,000–$80,000 |
| Monthly retainer | New docs, new intents, new channels, analytics, model upgrades | $2,000–$8,000/mo |
Per-conversation API cost typically lands $0.01–$0.05 depending on model mix and retrieval size. We model your specific volume and deflection economics in the discovery workshop.

Ready to cap your support headcount?
One 20-minute call. We'll look at your ticket volume, your docs, your help-desk stack, and tell you what's realistic to deflect — and what to leave for humans. If the math doesn't work at your volume, we'll say so.
