Let’s talk about Nexthink Spark

Powered by Nexthink. Engineered by Ellipsys.

What Nexthink Spark does

Help that arrives in the conversation.

Nexthink Spark is described by Nexthink as a personal IT agent for every employee. A person explains a problem in plain language, in a channel they already use such as Microsoft Teams. Nexthink Spark looks at what is happening on that person’s device and can resolve many everyday issues there and then, within guardrails that IT defines. When it cannot, it passes the issue to the service desk with the context attached.

Nexthink Spark is a Nexthink product, and the name belongs to Nexthink. This description reflects Nexthink’s public product page and documentation, checked on September 20, 2026.

Why Sentinel

The platform is excellent. The discipline behind it makes the difference.

Nexthink Spark gives every employee a personal IT agent inside the tools they already use. The platform is excellent. What separates a deployment that transforms your service desk from one that stalls is the discipline, the sequencing and the hands on engineering behind it.

That is where Ellipsys puts its focus. Spark Sentinel is built end to end around it: a start that puts readiness first, one engineering team throughout, a fixed path to governed production, and proof of value the day you launch.

How Sentinel works

Built once. Improved every week after.

Spark projects stall when the people who built the agent move on. With Sentinel, the engineers who configure your agent also supervise it in production: it arrives with an owner, a rhythm and a plan for what it learns next.

  2. Buildagent and automations

The line is how Nexthink Spark goes live. The loop is why it keeps getting better.

What you get

One service, from readiness to results your executives see.

  1. Ready before day oneA readiness guide and the analysis done ahead of time, covering ticket drivers, use cases and access mapping, all land before kickoff. Delivery opens with targets already chosen.
  2. One team throughoutThe same engineers and strategists, based in the United States, from design to daily supervision, on your business hours. Continuity of people means continuity of context.
  3. Engineering in productionWe build and test the automations, workflows and Remote Actions that let Nexthink Spark fix issues at the source, drawing on a mature automation library.
  4. Fluent across the platformNexthink Spark does not operate in isolation, and neither do we. It lands as an integrated capability alongside the rest of your Nexthink estate.
  5. Supervision every weekEvery Nexthink Spark conversation, whether resolved, escalated or abandoned, feeds a weekly review with documented improvement actions and full audit trails.
  6. Value your executives seeWe baseline ticket volume, resolution time and deflection, then report tickets avoided, hours returned and dollars saved each quarter.

The point

Nexthink Spark is what your employees see. Sentinel is the discipline behind it, keeping coverage, quality and measurable value growing long after go live.

We do not start the clock until you are set up to win. Your first week is spent on real fixes, not paperwork.

The Ellipsys readiness principle
Enterprise confidence

Confidence on both sides of the conversation.

An agent that acts on people’s devices has to earn trust twice: from employees who accept its help and from IT leaders who control what it may do. Nexthink provides the controls; experience is knowing how to use them.
What you see

Proof in your environment, early.

We measure launch in working examples. Early in the service, Nexthink Spark demonstrates each of its four core capabilities live in your estate, on the issues your ticket data says matter most.

Lane 1

Workflow action

An automated process with several steps that resolves an issue end to end, such as an Office repair sequence.

Lane 2

Remediation action

A single corrective fix on the device, such as restarting an application or clearing a cache.

Lane 3

Diagnostic check

A check that only reads, gathering the information needed to diagnose a problem before anyone touches it.

Lane 4

Ticket escalation

When human help is needed, Nexthink Spark opens a ticket in your service desk with the full conversation and context attached.

The rhythm

One method, run to a rhythm.

Sentinel applies the three Ellipsys operating capabilities to Nexthink Spark, and runs them to a steady cadence.
  1. 01

    Adopt

    Stand up a governed, stable Nexthink Spark that resolves real issues from day one and earns trust across IT.

    Working and strategy sessions, conversation reviews, and a written recap within a day.

  2. 02

    Transform

    Make Nexthink Spark part of the daily rhythm of IT, expanding coverage and tying every deliverable to a business outcome.

    Continuous

    Knowledge curation, automation library growth, guardrails and AI governance with full audit trails.

  3. 03

    Evolve

    Grow resolution rates and coverage year over year, so the value keeps compounding.

    Quarterly

    Value reviews with your leadership, measured against the KPIs we baselined together.

Choosing Ellipsys means the team that helps you plan is the team that builds, and the team that builds is the team that stays. The platform will impress you. What you will remember is how quickly it started paying off, and how little of that was left to chance.

What Nexthink reports

Nexthink reports that Nexthink Spark resolved 77% of Level 1 IT issues at first contact during the early adopter program (Nexthink press release, January 20, 2026). This is Nexthink’s product figure. It is not an Ellipsys delivery result, and what you see will depend on your own environment.

Ready when you are.

We will walk you through the readiness guide, shape the first use cases around your own ticket data, and have Nexthink Spark working live issues in your environment fast.
