Headcount: 56 (+229%)
Specialism: Microsoft
HQ: London
Owned and led by former Insight and Quantiq bigwig Stuart Fenton, this ambitious Microsoft partner is aiming to add another 30-40 heads in 2026.
Companies House accounts show its average monthly headcount rising from 17 to 56 between calendar 2021 and 2024. Employee numbers have since rising to 95, it told us.
The London-based outfit counts Power Platform, Dynamics 365 and AI among its Microsoft sweet spots.
2026 will see organisations move from trialling AI to full adoption of agentic services, Fenton tells us (see below).

Q&A with Ingentive CEO Stuart Fenton
How have you been able to increase headcount in a flat market?
We have the benefit of being in a part of the market including Dynamics and AI that is growing faster than the overall market. Additionally, we added more capabilities in order to provide more services to our clients. On average we grew over 100% in 2025 and for January 2026, our growth rate was 177%. Headcount is a shade under 100 heads now and we expect to add between 30 and 40 heads during 2026.
What mega trend do you think will most shape the year for your company?
This year remains the year of AI transformation as we move from organisations trialling technology to full adoption of agentic services to reduce white collar headcount.
Which competitor or peer do you respect the most, and why?
We do not really have direct competitors for the overall business, but pieces of the business compete with various others. I think Transparity and Infinity are great firms in an overlapping space. Kainos too has some decent skills in AI.
What’s a fact or quirk about your company most people won’t know about?
Our growth rate continues to be really strong and while still pretty small, we expect to catch many of our competitors through organic growth.
Does the rise of AI and automation make it less likely you’ll continue to add headcount at the same rate in the coming years?
The correlation between headcount growth and revenue growth is broken because of AI. We are no different. We need half the resources in back-office functions than would have needed even three years ago. We already have a number of agents performing tasks in the business and this will dramatically increase through 2026.
