Nikhil Kamath-backed KNAV acquires UK accounting firm

• KNAV, a global accounting + advisory firm (HQ in Atlanta, born in Mumbai), has acquired Aventus, a UK-based accounting firm based in London.
• This one’s a game-changer for the India–UK–US–Europe corridor. 
• It’s KNAV’s third major acquisition in 12 months.
• FYI: In 2024 KNAV’s overall revenue was $35.5Mn!

First, KNAV tapped the US-India corridor

Founded in Mumbai in 1999, KNAV was created with a vision to serve businesses in the US-India corridor.

Since then, KNAV has grown to become one of the fastest-growing firms in the accounting space, with a strong presence in seven countries:

• US
• Canada
• UK
• Netherlands
• India
• Singapore
• Philippines

They have over 600 professionals worldwide.

In FY24, KNAV US reported $35.5M in revenue. And 2025? All signs point to a much higher number.

KNAV is also recognized as one of the fastest-growing CPA firms by Accounting Today.

Next, India-UK-Europe corridor

On 16th April KNAV announced its acquisition of Aventus, a UK-based accounting firm based in London.

This is KNAV’s third acquisition in 12 months, following:

• HLG in the Netherlands
• Natarajan & Swaminathan in Singapore

So, who is Aventus?

Aventus is a UK-based firm known for audit, tax, financial reporting, and outsourced finance services.

They’re also a fellow Allinial Global member—just like KNAV—which makes this integration smoother and more aligned.

With this deal, 4 partners and 27 professionals join KNAV’s UK operations

Why this acquisition matters

• India-UK corridor: The UK remains a critical market for Indian businesses, serving as a gateway to Europe. The India-UK corridor is growing in importance, especially as Indian companies continue to expand their footprint internationally. This acquisition puts KNAV in a stronger position to support those businesses.

• Local strength meets global capability: Aventus brings local know-how; KNAV brings international scale. Together, they offer clients the best of both worlds.

• Expanding regional presence: With strongholds in the US, Netherlands, and Singapore, the UK was a natural next step for KNAV’s global roadmap. Important step for KNAV as it continues its global expansion.

• With 90% of the India-UK Free Trade Agreement already agreed upon, this corridor is only going to get hotter.

How does this affect KNAV’s strategy?

KNAV’s model has always focused on being a “One Firm”—meaning consistent, collaborative service delivery across all locations.

This deal could help KNAV, replicate what worked in the US (where it’s among the top 300 CPA firms)—now in the UK.

By pairing India’s technical teams with local delivery from Aventus, clients benefit from both efficiency and on-ground support.

What KNAV’s leadership is saying

Vaibhav Manek, CEO of KNAV India, put it best:

“This merger reflects our commitment to building a globally integrated practice anchored around our exceptionally talented team in India.”

He added that the UK is key to their global corridor strategy—right up there with the US, Netherlands, and Singapore.

In case you forgot…

Nikhil Kamath’s US investment arm NKSquared took a minority stake in KNAV back in 2024.

Here’s what he had to say now:

“KNAV is building a truly global professional services firm—one that brings together local insight, cross-border capability, and world-class leadership.

This integration reflects the kind of forward-looking, execution-driven growth that we are proud to support.”

The big picture…..

KNAV is quietly becoming a truly global firm—especially for clients operating between India, US, UK, and Europe.

This latest deal:

• Strengthens UK operations
• Supports Indian multinationals expanding abroad
• Delivers on KNAV’s “One Firm” promise
• Positions KNAV to compete at the highest level in both the US and UK markets
