About
Senior engineering,
without the overhead.
One senior engineer who plugs into your team — in the CTO seat, at the keyboard, or both. Architecture, hands-on development, and technical strategy without a full-time hire.
IN2Labs helps startups, research groups, and established companies make the right technical decisions and ship production software — as a fractional CTO, as a contract engineer, or both. Work happens directly with founders, principal investigators, and technical leaders, not through account managers or layers of junior staff.
IN2Labs is deliberately a one-person senior practice out of Boston — not an outsourcing operation with a bench of interchangeable developers, and not a principal who wins the work and hands it to someone junior. The engineer you talk to on the first call is the one who designs your architecture and writes your code, because there is nobody else to hand it to. Clients are not limited to New England — the practice works nationwide.
"If it doesn't ship, it isn't research — it's a slide deck."
Eric P. Hassey, the founder, has 15+ years across government systems and consumer apps — including R&D at MIT and, separately, service as principal investigator on an NSF SBIR Phase I award at Preventa Medical Corporation. That's the same research rigor and production discipline behind every engagement, whether it's a two-week technical triage or an ongoing fractional CTO role.
Client work
Preventa Wellness
A preventive-health platform where I have been CTO since 2019. Encrypted health data, audit logging, and BAA-covered infrastructure, architected for regulated health data from day one. If you're building in health tech, I've already solved the compliance problems you're about to hit.

IN2Labs also ships products of its own — that R&D lives at in2labs.studio.
How the work runs
01
Understand first
Understand the problem and your constraints deeply before writing a line of code.
02
Ship constantly
Working software beats slide decks. Ship to production early and often.
03
You own the IP
Clean ownership, end to end. What gets built for you is yours, full stop.
04
Right-sized tech
The simplest architecture the problem demands — never more.
