As of November 11, 2026, Knowlify describes itself as “an AI-native Meta ads agency that creates and improves video ads weekly,” with campaign management available as an option. It says it serves “B2B, B2C and D2C” companies; its site does not describe a SaaS-specific practice.
Plans “start at $5,000 a month, for creative with campaign management or creative alone,” with “no annual contract” and media spend paid separately to Meta. Knowlify publishes a 30-day guarantee. Its own guide notes that its UGC-style ads “use AI presenters, not real people.”
Choose it when: creative volume is your bottleneck and you are comfortable with AI-produced video.

GrowthSpree calls itself “an AI-native marketing agency for B2B SaaS and B2B companies” that runs paid media, ABM, RevOps and search as one system, across Google, LinkedIn, Meta, Reddit and others. It says it is not a fit for “B2C brands, consumer apps, ecommerce, and DTC companies.”
Its company fact sheet lists a “flat monthly retainer starting at $3,000/month” for paid media, ABM and RevOps, with “no percentage-of-spend” and terms of “month-to-month, cancel anytime.” Its Meta page says Conversions API and HubSpot or Salesforce offline events are included, and that it does not offer video production.
Choose it when: you want Meta run as one channel inside a broader B2B pipeline program at a low published starting retainer.

Flighted describes itself as a “performance marketing agency specializing in Meta ads for ecommerce and B2B SaaS brands spending $25k+ a month,” and also runs TikTok and Google.
It publishes “a flat monthly retainer from $5,000, with no percentage-of-spend fees” and a “minimum ad spend: $25K a month.” Its pricing guide states “month to month after a two-month testing period” and that campaigns are usually live within two weeks.

Choose it when: you are a funded B2B SaaS company that wants LinkedIn and Meta run together by a SaaS-only team.

KlientBoost is a performance marketing agency covering paid ads, SEO, conversion rate optimization and email. Its Facebook ads page covers “eCommerce, SaaS, or lead-gen” campaigns.
A fee is not published. It says “Sometimes a percentage of ad spend makes the most sense. Other times, a flat fee works better,” and it offers pay-for-performance. It works with budgets “from as little as $5,000 per month,” and for bigger goals recommends “at least a timeline of 6 months.”
Choose it when: you want a choice of fee structure, including performance pricing, and conversion rate work alongside ads.
It depends on what you need. Raintree Ads fits if you want the founder running your account at a flat $2,400 a month. GrowthSpree and Hey Digital fit if you want Meta inside a multi-channel B2B SaaS program, Flighted fits accounts spending $25K or more a month, and Knowlify fits if creative volume is the gap.
Of the seven agencies here, four publish a starting fee: Raintree at $2,400 a month flat, GrowthSpree from $3,000, and Knowlify and Flighted from $5,000. Hey Digital, Directive and KlientBoost do not publish a fee. Ad spend is paid to Meta on top of any fee.
Yes, when the account optimizes for pipeline instead of form fills. Sending CRM stages like SQL and opportunity back to Meta teaches the algorithm which leads close. In our FlexiBake case study, cost per lead fell 74% and lead volume rose 289%.
It varies. Flighted publishes a $25K a month minimum, KlientBoost works with budgets from $5,000 a month, Hey Digital gives Meta spend guidance of $3K to $8K a month at Series A, and Raintree’s best fit is $10,000 or more a month in Meta spend.
Hire a Meta specialist when Meta is a core channel and you want depth on creative and measurement there. Hire a multi-channel agency when you want one team running LinkedIn, Google and Meta together. Raintree is Meta-first, with other channels available as add-ons.
