Webinar Replay: The Future Is Fractional — How Part-Time Devs Can Drive Startup Growth

The fractional hiring model is not new — but the scale at which startups are adopting it is. This webinar captures a live conversation between two practitioners who have been building and placing fractional engineering talent for years, covering the real mechanics of what makes it work.

What does this webinar actually cover?

The session is structured around three questions that founders and engineering leaders ask most often when considering fractional hiring for the first time.

First: what are the real benefits of working with part-time developers — not the marketing version, but the operational reality? Second: how do you manage a fractional team so it performs like an internal team instead of an outsourced vendor? Third: when does a fractional CTO or head of engineering make sense, and how do you know if you are at that point?

The panel doesn’t hedge on any of these. Both speakers have spent years on both sides of these engagements — as fractional practitioners and as operators who hired fractional talent — so the answers are grounded in what actually happens, not theory.

The webinar also covers the path from fractional to full-time — arguably the most underappreciated benefit of the model. Working together part-time for two or three months gives both parties a signal quality that no interview process can replicate. The trust gap that usually makes senior hiring risky gets closed through demonstrated collaboration instead of educated guesswork.

Who are the expert speakers in this webinar?

The panel brings together two MIT computer science alumni with extensive real-world fractional experience — one focused on the supply side of part-time tech work, and one on the demand side.

Ernie Park, Founder, Part-Time Tech

Ernie Park has been featured in the Wall Street Journal and Good Morning America for his work evangelizing part-time work in tech. A former engineering leader at HubSpot and Brex, and a YC S12 alumnus through MicroEval, Ernie studied computer science at MIT before spending years inside high-growth companies building the kind of engineering teams that fractional models are now replacing for many startups.

He founded Part-Time Tech to share the research, frameworks, and practical resources he developed for engineers who want to work part-time — and for companies that want to hire them without losing the rigor they would expect from a full-time hire.

Praveen Ghanta, CEO and Co-Founder, Fraction

Praveen Ghanta is a serial entrepreneur, software developer, professional investor, and operator who has been on both sides of the fractional hiring equation. He spent time as a fractional developer in the early 2000s, then employed fractional developers at his startup HiddenLevers — which he founded and exited in 2021 at 16x revenue. He now leads Fraction, a platform that matches senior fractional engineers, designers, and growth operators with SaaS companies that need embedded senior talent without the overhead of a full-time hire.

How does the fractional hiring model actually work in practice?

The mechanics of fractional hiring are simpler than most founders expect, but the management implications are not. The model works when companies treat their fractional hire the way they would treat a senior employee — with full context, real accountability, and a clearly defined scope — not the way they would treat a contractor handed a ticket queue.

Fractional developers typically operate on a weekly rhythm: async check-ins, sprint participation, and direct access to whoever owns the product decisions. The constraint is hours, not access. A fractional engineer with 15 hours per week is more useful when those hours are allocated to high-leverage work — architecture decisions, code review, unblocking junior engineers — than when they are spread across shallow tasks that don’t compound.

The webinar covers specific practices for onboarding, sprint planning, communication cadence, and performance review that make part-time collaboration function at full-time quality. These are not generic management frameworks — they are patterns that Ernie and Praveen have tested across dozens of engagements and refined based on what actually broke.

When does a fractional developer outperform a full-time hire?

The clearest use cases are also the most common: post-seed companies that need senior technical judgment before they can justify a full-time engineering lead salary; teams that need to scale development capacity on a six-month runway without locking into multi-year compensation packages; and founders who want to evaluate a candidate’s actual work before making a full-time offer.

But the webinar goes deeper than the obvious cases. The panel discusses the specific signals that tell you a fractional arrangement is working — and the signals that tell you it is time to convert to full-time. The threshold is not purely budget. It is about whether the company’s core engineering work has become continuous enough, complex enough, and strategic enough to require a full-time presence.

The case for fractional hiring as a solution to the talent wars makes the structural argument: in a market where senior engineers are expensive and scarce, fractional arrangements let startups access talent they could not otherwise afford to hire, while giving engineers a working structure that matches how senior professionals actually prefer to work at this stage of their careers.

How do you manage part-time developers without losing velocity?

The management question is where most fractional arrangements succeed or fail — not in finding the right person, but in giving them what they need to do their best work in limited hours. The webinar addresses this directly with the practices Ernie and Praveen have seen work across different startup stages and team structures.

The core principle: fractional developers need fewer meetings and more context. The time investment that costs a full-time employee an afternoon costs a fractional employee a material percentage of their weekly allocation. The teams that get the most from fractional engineers are the ones that invest in async documentation, clear sprint goals, and minimal coordination overhead.

The panel also covers the emotional dynamics of part-time work: how fractional developers signal commitment without being always-on, how managers learn to calibrate expectations against hours rather than presence, and how the relationship evolves as trust builds. These dynamics are specific to the fractional model and are not well covered in standard engineering management literature — which is part of why this webinar exists.
