Drift vs Intercom vs a Custom AI Agent: Which Should You Pick in 2026?

Drift was the poster child of conversational marketing — until Salesloft bought it, Clari bought Salesloft, and the combined company announced Drift's sunset in March 2026. If you're searching "Drift vs Intercom" right now, you're probably not comparing features. You're trying to figure out where to go next without setting fire to your pipeline.

TL;DR

• Drift is on a shutdown clock. After Salesloft bought it in 2024 and Clari merged with Salesloft in late 2025, its sunset was announced March 6, 2026, with 1mind named as the successor. Treat it as a migration, not a comparison.
• Intercom Fin is the closest like-for-like replacement, but it charges per seat plus $0.99 per AI resolution. Predictable at low volume, painful at high volume.
• A custom AI agent is the third path: a fixed-fee build you own outright, no per-conversation fee, wired into your own data and CRM.
• Buy the SaaS tool if your flow is generic and you want to ship this week. Build custom if your qualification logic is specific, or if per-resolution fees would scale into real money.
• Not sure which? The $497 AI Profit Leak Audit models your actual conversation volume and tells you which is cheaper over 12 months before you sign anything.

The state of play in 2026

The conversational-AI landscape shifted hard this year, so a fair comparison has to start with reality, not the marketing pages.

Drift no longer exists as an independent product. It was folded into Salesloft after the 2024 acquisition, and following the Clari–Salesloft merger in December 2025, the combined company announced Drift's gradual sunset on March 6, 2026 and named 1mind as the exclusive successor. Pricing was never transparent — the Premium tier started around $2,500/month with mandatory bundling, and higher tiers were quote-only. If you're a current Drift customer, the decision in front of you isn't "keep Drift or switch" — it's "migrate to what."

Intercom went the opposite direction: all-in on AI with its Fin agent. It's a mature, well-supported platform and the natural like-for-like replacement for a lot of Drift use cases. The catch is the pricing model (more on that below).

A custom AI agent isn't a product you buy off a shelf — it's an agent built around your specific funnel, your data, and your systems, that you then own. For a business whose lead-qualification or support logic is genuinely specific, this is increasingly the option that pencils out.

The honest comparison

Here's how the three stack up. Pricing and product status are as of June 2026 — SaaS pricing changes often, so verify before you commit.

Here's the number that bites: Intercom's Fin agent costs $0.99 per resolution on top of seat fees (Intercom pricing, 2026). At 500 resolved conversations a month that's about $495 in AI fees alone. At 5,000 it's roughly $4,950 a month, and it keeps climbing as you grow. A custom agent flips that math. You pay once to build, then cover only your own model and infra cost per conversation, which is usually cents rather than dollars. The more volume you run, the worse that per-resolution fee gets and the better a build looks.

When off-the-shelf (Intercom) is the right call

Don't over-engineer this. Buy the SaaS tool when:

• Your support or chat flow is generic — FAQs, order status, basic triage — and a vendor's pre-built agent already fits.
• You want to be live this week, not in a month.
• Your conversation volume is low to moderate, so $0.99/resolution stays comfortably below what a build would cost to amortize.
• You don't have anyone to own infrastructure and you'd rather pay a vendor to handle uptime.

For a lot of teams, Intercom Fin is genuinely the right answer. We'll tell you that if it's true.

When a custom AI agent wins

A custom build is the better call when:

• Your qualification or routing logic is specific to your business — scoring leads on signals only you care about, routing by rules a generic bot can't express. (This is exactly where conversational lead-gen tools like Drift were used, and exactly where SaaS hits a ceiling.)
• Your volume is high enough that $0.99 × every conversation becomes a real line item.
• You need the agent wired natively into your own data — your product database, your CRM, your internal tools — not bolted on through a vendor's integration layer.
• Ownership matters. You keep the code and the asset instead of renting it and being exposed to the next acquisition or sunset. (Ask any Drift customer how that feels right now.)

This is the same build-vs-buy question we walk through in detail in Build vs. Buy AI for Your Business — the framing there applies directly to chat and conversational agents.

The migration angle (if you're on Drift today)

If you're currently running Drift, you have a deadline whether you like it or not. Two honest paths:

1. Lift-and-shift to Intercom Fin — fastest, lowest-effort, and fine if your use case is generic. You'll trade a sunset risk for a per-resolution bill.
2. Rebuild as a custom agent around your actual funnel — more upfront work, but you come out owning an agent tuned to your qualification logic with no per-conversation fees. If Drift was doing real lead qualification for you, this usually wins over a 12-month horizon.

The trap is doing nothing until the sunset forces a rushed migration. Decide now while you have leverage. If you want help scoping the rebuild option, book a call and we'll map your Drift setup to what a custom agent would cost to run.

What this looks like as a build

A custom conversational agent isn't a science project. A typical scope:

• Discovery + design — map your qualification logic, data sources, and routing rules.
• Build — the agent, the integrations into your CRM/data, the handoff-to-human path.
• Production from day one — deployed on your infrastructure, monitored, with the conversation logic you control.

Most builds land in the 4–12 week range depending on integration depth. You can see how we scope conversational agents — including lead qualification — in AI Lead Qualification Automation, and how we run builds end-to-end on the AI Agent Development page.

The bottom line

"Drift vs Intercom" isn't really the question in 2026 — Drift is leaving. The real question is whether your conversational flow is generic enough to rent from Intercom, or specific enough to own as a custom build. If you're paying $0.99 per resolution on thousands of conversations, or your qualification logic is the actual competitive edge, owning beats renting.

Get the $497 AI Profit Leak Audit and we'll model your real conversation volume against both options and tell you, in writing, which one is cheaper over the next year — and what the build would take if custom wins.
