908 Devices	Manufacturing	230	$50M	United States	TriNet HR Corporation	TriNet PEO	PEO (Professional Employer Organization)	2022	n/a	In 2022, 908 Devices deployed TriNet PEO in a PEO (Professional Employer Organization) arrangement to centralize payroll and HR-related workforce administration for approximately 200 employees. The deployment covered the company headquarters in Boston, MA, a satellite office in North Carolina, and a distributed remote employee population, and it established a biweekly payroll cadence for multi-state exempt and non-exempt payroll processing. TriNet PEO was configured to support core payroll processing, payroll accounting and tax withholding workflows, and benefits and retirement contribution administration. Functional capabilities implemented included biweekly payroll runs, post-payroll general ledger postings, payroll accruals and reconciliations, unemployment insurance and benefit deduction handling, commission processing, and administration of employee stock purchase program offering periods. The implementation integrated TriNet PEO operations with equity plan administration via an outside Shareworks/Morgan Stanley platform, maintaining alignment of payroll tax withholdings and equity release data between TriNet PEO and Shareworks. Operational workflows required coordination with Finance for bank funding and month-end close tasks, and with Legal and Human Resources for grant approvals and equity plan governance, reflecting cross functional data flows for compensation and stock plan events. Governance and process changes were formalized through payroll process and procedure documentation, development of training documentation, and designation of a Payroll and Equity Specialist reporting to the Controller to act as the primary internal resource. The role supported escalated employee payroll inquiries, liaison work with external auditors, and operating procedures that reconciled payroll outputs from TriNet PEO with internal accounting controls and equity administration processes.
Aaptiv	Leisure and Hospitality	150	$15M	United States	TriNet HR Corporation	TriNet PEO	PEO (Professional Employer Organization)	2018	n/a	In 2018, Aaptiv implemented TriNet PEO in the PEO (Professional Employer Organization) category to outsource core HR services and establish an employer of record relationship with TriNet HR Corporation. Aaptiv is a New York City based mobile fitness company that experienced rapid headcount expansion, growing from 10 to 70 employees within a year and operating with a broader employee base reported at 150, and the TriNet PEO engagement was positioned to provide a scalable HR administration layer for that growth. The TriNet PEO deployment centralized payroll processing, benefits administration, and compliance management, while providing HR technology services to reduce manual administrative work. Functional capabilities implemented included payroll processing and tax filing, benefits enrollment and administration, workers compensation administration, and HR administration workflows that supported the People Operations function. TriNet PEO served as the operational backbone for routine HR transactions, enabling systematic onboarding and benefits provisioning aligned to a high-growth leisure and hospitality workforce. Governance and operational impact focused on shifting transactional HR ownership to TriNet, which freed Aaptiv’s Head of People Operations and leadership to prioritize talent attraction and retention. Company executives Ethan Agarwal and Tanaz Mody reported that TriNet’s services and technology provided peace of mind by handling payroll and benefits professionally, and helped Aaptiv position employee benefits as a recruiting and retention advantage. TriNet is also recorded as a customer of Aaptiv’s product, indicating a reciprocal commercial relationship between the two organizations.
Adcentrx Therapeutics	Life Sciences	50	$5M	United States	TriNet HR Corporation	TriNet PEO	PEO (Professional Employer Organization)	2021	n/a	In 2021, Adcentrx Therapeutics implemented TriNet PEO, a PEO (Professional Employer Organization) solution to centralize HR and payroll functions. The engagement ran November 2021 through February 2022 and was led by the Director of Finance and Human Resources at Adcentrx Therapeutics, a San Diego biotechnology start-up focused on protein conjugate therapeutics. TriNet PEO was configured to provide core HR and finance capabilities including payroll processing, administration of employee benefits, time off management, and expense reimbursement. The implementation included TriNet Transamerica 401K plan setup and payroll-to-401K linkage to support retirement contribution processing. Accounts payable transaction handling was documented and operationalized, with flow charts developed to standardize payables workflows. Operational coverage concentrated on HR and Finance functions across the company's approximately 50 employees in the United States, centralizing payroll and benefits administration through the TriNet payroll platform. The deployment aligned payroll cycles, benefit enrollment, time-off workflows, and expense reimbursement routing within TriNet PEO to create unified personnel and payroll records. Governance changes included preparation of a consolidated budget and defined cost centers to map payroll and benefits expenses into finance reporting, and the development of process diagrams for accounts payable to enforce consistent procedures. Rollout sequencing followed the November 2021 to February 2022 schedule, progressing from initial payroll and benefit enrollments to 401K activation and formalized AP process documentation.
