Artisan's Ava SDR added 800+ B2B customers in Q1-Q2 2026 against fierce competition. We pull the deployments, the per-seat pricing. The 30-day picture for buyers and operators.
Key takeaways
Artisan hit a milestone in April 2026 worth pulling apart in detail. Most coverage focused on the launch event and the funding number — the actual interesting story is in the deployment numbers, the new pricing model, the named enterprise customers signing in the first 30 days, and the architecture decisions buyers are making in response.
We'll walk through the announcement, the platform architecture as documented in vendor materials, the customer wins we have public confirmation on, the comparable vendors buyers are evaluating against in RFPs, and the procurement watch-outs that come up repeatedly in the contracts we've reviewed.
The deployment architecture across the named customers in the last 30 days converges on a small set of decisions that buyers should expect to make:
The teams that skipped any of these are the ones reporting reliability issues two months in. The ones that built all six in are the ones expanding to new use cases.

When you're at the contract stage, the lines that matter most:
The contract terms are where buyers leave the most money and the most leverage on the table. Spend the legal cycles before signing.
The sales and marketing vertical has agent-deployment specifics that don't show up in horizontal coverage and matter at procurement:
The vendors winning in sales and marketing are the ones that built around these constraints from day one rather than retrofitting them onto a horizontal platform after the fact.
The shortlist this segment most often produces in 2026:
The right answer depends on the existing stack, the in-house capability, the willingness to commit to a platform vendor for three or more years, and the strategic importance of the workflow being automated. There is no universal correct choice.

What's the difference between an AI assistant and an AI agent? An assistant suggests; an agent acts. Production sales and marketing AI agents in 2026 take real actions in real systems — booking, refunding, escalating, scheduling, drafting — and those actions are auditable. The shift from assistant to agent is what's driving 2026 budgets.
What's the right model for a sales and marketing AI agent? For most production deployments: Claude Sonnet 4.6 or GPT-4.1 for the reasoning loop, Haiku 4.5 or GPT-4o-mini for tool execution, Opus 4.7 for the hardest reasoning steps with explicit cost guards. Mix-and-match by intent class.
How do we measure agent quality in production? Resolution rate, customer satisfaction (CSAT or equivalent), escalation rate, escalation reason distribution, latency P95, cost per resolved conversation. All six together. Any one in isolation is misleading and will optimize the wrong thing.
Do we need MCP for an enterprise sales and marketing agent? Not strictly required, but increasingly the standard. New tool integrations are 5-10x faster to build via MCP than custom function-calling implementations, and the spec stabilization in early 2026 made it the default choice for new builds.
