The senior buyer decision

Fractional vs Agency vs In House.

Three engagement shapes. Three different bets. The wrong call here costs months and six figures. This page is the senior buyer’s decision framework: when to pick which, when to combine them, and what the actual numbers look like in 2026.

TL;DR · Start fractional. Move what works in house.

Senior team velocity vs mixed staffing

The verdict

Most teams move fastest by starting fractional, then transitioning what works in house.

Fractional shapes the system at senior speed. In house inherits it once the path is clear. Agencies fit narrow well scoped work in parallel. The teams that get this sequencing right move faster and waste less than the teams that pick one shape and stick to it.

01 · The three shapes

Senior, multidisciplinary, embedded. Owns strategy through engineering and operation. Engaged per engagement, not per seat.

Mission critical work where the path is still ambiguous and the buyer needs senior speed without adding headcount.

03 · How to choose

Four scenarios · One recommendation each

01

Pick · Fractional

New category, ambiguous path, senior team needed yesterday.

You are building something that has never been built. The path is still being discovered. You need senior people who can make decisions, not execute against a SOW. Fractional moves now and shapes the system. In house would take six months to even start.

02

Pick · Agency

Defined scope, known patterns, fixed deliverable.

You know exactly what you want. The pattern is known. The deliverable can be specified up front. An agency is purpose built for this and pricing is predictable. Fractional is overkill, in house is overhead.

03

Pick · In house

Mature product, stable scope, multi year horizon.

The product is real. The scope is stable for the next two to four years. You can attract and retain senior talent in your category. In house compounds. Fractional and agency burn money against a problem that no longer needs outside speed.

04

Pick · The hybrid

Most companies, most of the time.

Start fractional. De risk the build. Establish the system. Once the path is clear and the work is stable, transition what works in house. Use agency for narrow, well scoped projects in parallel. The teams that get this right move faster and waste less.

04 · Frequently asked

Common questions from senior buyers.

What is a fractional product team?

A fractional product team is a senior multidisciplinary team (product, design, engineering) engaged per engagement instead of hired full time. It delivers staff level continuity without the fixed cost and ramp of in house headcount. Bttr. operates as a fractional product team.

Fractional product team vs agency · what is the actual difference?

A traditional agency delivers artifacts to a scope, then hands off. A fractional product team owns strategy through engineering and operation, with senior people doing the work rather than selling it. Fractional is better when the product is mission critical and the path is still ambiguous. Agency is better when scope is fixed and the path is known.

When should I hire in house instead?

Hire in house when scope is stable and predictable for two or more years and you can attract and retain senior talent in your category. Use a fractional team to move now, de risk the build, and establish the system the in house team later inherits.

Which is fastest to start?

A fractional product team starts in days. An agency takes weeks for scoping, SOW, and account ramp. In house hiring takes months to recruit, onboard, and form a working team. If the timing pressure matters, the answer is fractional.

Is fractional cheaper than in house?

For the same work over a fixed window, fractional is usually higher day rate but lower total cost because there is no recruiting, no benefits, no ramp, no bench, no retention overhead. For ongoing stable work over years, in house wins on cost. The break even depends on the scope and the retention dynamics in your market.

Can I mix all three?

Yes, and most strong companies do. Fractional for the senior, ambiguous, strategy through engineering work. Agency for narrow scoped deliverables (a brand refresh, a specific campaign build). In house for the day to day operation of the system once the path is clear.

How does Bttr. engage fractionally?

Bttr. is a senior only team that engages per engagement, not per seat. The people who pitch are the people who ship. We typically run a fixed timebox sprint to establish the system, then transition into a stewardship retainer or hand to the client team. See the engagement models page for the four shapes we offer.
