What Astira Capital Partners buys

Astira Capital Partners is a Boston private equity firm founded in 2023 by Azra Kanji, a former partner at Abry Partners. It closed its first fund at $675 million in October 2023, above its $500 million target. Astira buys business-to-business specialist services companies, where skilled professionals do high-value work for clients with help from data and technology. Its focus areas include office of the CFO services, financial services, professional and legal services, risk and compliance, marketing and information services, human capital management, digital and AI services, and supply chain and logistics.

It targets companies with $10 million to $30 million of EBITDA and $25 million to $250 million of revenue, putting $50 million to $250 million of equity into each platform. It takes control or structured minority stakes, expects founders and managers to keep real ownership, and plans to partner for roughly five years or more. Its platforms are Altus, CallRevu, ConData and Numera. Smaller firms are most likely to meet Astira as add-ons, as KBS CFO and Calldrip did in 2026.

Greymont’s take

How Astira Capital Partners fits a seller

Astira suits owners of larger specialist service firms, such as accounting, collections, audit or analytics businesses with at least $10 million of EBITDA, who want a buyer that will spend on technology and AI and help them make acquisitions. It expects founders and managers to keep a real ownership stake, so a sale usually means cashing out part of the business now and holding the rest for a later sale. It also buys divisions of larger companies, as with Altus, which it carved out of another investor's portfolio company.

Smaller firms mostly fit as add-ons, especially accounting and CFO practices joining Numera, which Astira says has added four practices since it invested. Owners should ask how their brand and staff will fit the platform, since Numera is folding ten legacy brands into one name, and what Astira's roughly five-year horizon means for any equity they keep.

Questions owners ask

What size companies does Astira Capital Partners buy?

Its criteria call for $10 million to $30 million of EBITDA and $25 million to $250 million of revenue, with $50 million to $250 million of equity invested in each platform.

Does Astira Capital Partners take minority stakes?

Yes. It makes control investments and structured minority investments, and in both cases it wants founders, partners and managers to keep a meaningful share of the ownership.

Will Astira buy a small accounting or CFO services firm?

As an add-on, yes. Its platform Numera, an outsourced accounting, tax and CFO services firm in Plano, Texas, bought KBS CFO in October 2026 and Decimal's direct services business in April 2026.

How large is Astira's fund?

Astira closed its first fund, Astira Capital Partners Fund I, at $675 million in October 2023, about five months after launch and above its original $500 million target.
