Zephyr Business Group

What Zephyr Business Group does

Zephyr Business Group LLC is a privately held business services firm headquartered at 1 Washington Mall, Boston, MA, founded in 2018. The company delivers integrated back-office financial services and fractional CFO expertise to a horizontally segmented client base spanning early-stage startups (pre-seed through Series C), small and medium businesses, non-profit organizations, and solo entrepreneurs. Its core product is the Complete Back Office Solution (bookkeeping, HR and benefits, bill pay, AR/AP management) starting at $1,000/month, supplemented by premium Fractional CFO Services starting at $1,500/month and a $150/month solo entrepreneur offering branded Zephyr for One.

The company's service delivery model is built on a curated third-party technology stack — QuickBooks Online for GAAP-styled bookkeeping, Gusto for payroll/HR/benefits, and Bill.com for accounts payable — combined with human bookkeepers and bespoke financial modeling. Zephyr differentiates through customized financial models built from scratch per client, sliding-scale pricing tied to client revenue and capital raised, and a bundled service approach that consolidates functions typically sourced from multiple vendors. Services are sold via direct website sales and a referral program with $500 payouts, and delivered remotely across all 50 US states plus DC.

Zephyr serves 60+ clients with cumulative reported client capital raises of $340M+ and operates without external institutional funding or disclosed revenue figures. The leadership team includes Managing Partner & CEO Alec Lai, VP of Client Services & Experience Sarah Chapdelaine, and Director of FP&A Sydney Belcher, supported by two junior financial staff. The firm has built adjacent partnerships for tax and filing services (Accountalent, CorpNet) and benefits administration (Vita, Justworks), extending its addressable service surface without internal build-out.
