What to look for
- Ask how many concepts and variants they ship per month and how tests are read.
- Check who writes briefs and who decides which ads to cut.
- Confirm usage rights for creator footage before production starts.
- If you sell to Boston's student or healthcare-adjacent audiences, ask for examples aimed at similar audiences rather than generic consumers.
- Ask how quickly a winning Boston test becomes new variants, and who approves them on your side.
How we picked
Each agency has a published Growth Partner Confidence Score and an official source documenting performance creative work, linked on its card. For this page, each agency has a documented offer or case for ad creative built for testing. Agencies with a Boston-area office are labelled; the others are listed as remote options from their US location (or documented US campaigns) and client work, an editorial suitability judgement rather than a verified remote-service promise. Scores were not changed for this page, and results quoted from agency sources are self-reported.

Frequently asked questions
- What does a performance creative agency do?
- It researches angles, scripts and produces ad variants, then uses paid results to decide what to make next. Some also buy the media; many hand ads to your media team.
- Are these agencies based in Boston?
- Fetch & Funnel (177 Huntington Ave, Boston, MA) has an office in the area. The other agencies are included as remote options based on documented work. Each card shows the agency's actual base. Confirm availability and any in-person requirements.
- Can a remote agency handle a Boston brief?
- Usually, for strategy, media and most creative. If you sell to Boston's student or healthcare-adjacent audiences, ask for examples aimed at similar audiences rather than generic consumers.
- How much do performance creative agencies charge?
- Engagements are usually a monthly retainer tied to creative volume; production days and creator fees can be extra. Each profile lists the agency's disclosed budget band where available.
