Kalungi: What It Is, Who It's For
Kalungi is a B2B SaaS marketing agency that sells a fractional CMO plus an execution team under one retainer. Its homepage lists CMO-as-a-Service, CMO coaching, ABM, RevOps and HubSpot optimization, branding and design, paid media, content and SEO, and web development. It builds its approach on the T2D3 growth framework from founder Stijn Hendrikse. Two competitor pages say it was founded in 2018, but Kalungi's homepage does not state a founding year. Sources disagree on location. Kalungi's site gives a Kirkland, Washington address, while two competitors say Seattle. Kalungi announced on March 16, 2026 that Antoine Vial became CEO, with Hendrikse staying on as Chairman. We read that announcement only as a search snippet.
It is built for B2B SaaS companies that want one vendor to own strategy and execution and can fund a large retainer. Kalungi's homepage claims 280+ SaaS clients served. Seed-stage companies and teams that want performance-only SEO or AI search work should look elsewhere. We found no AI or GEO offering from Kalungi, so it sits in this category as a B2B SaaS agency, not an AI specialist.
What Kalungi Actually Does
Kalungi sells three engagement models on its homepage. Full Service targets SaaS companies at $5MM to $10MM ARR and is said to replace 10+ hires, with pay-per-performance available. Syntropy targets $1MM to $5MM ARR teams, where Kalungi advises and the client's team executes. T2D3 targets pre-PMF and seed companies with playbooks and templates.
Per a competitor's description, each client gets an Associate CMO for day-to-day leadership, supported by specialists. The workflow runs from consultation to a roadmap presentation, onboarding and execution. One search snippet mentions 4 to 6 weeks of onboarding, which we could not trace to a source.
Kalungi is not independently verified for output quality. The most consistent criticism comes from competitors: a high price floor, a thin G2 base and single-vendor dependency. Treat those as opinion, not findings.
Kalungi Pricing
Kalungi publishes no pricing. Figures below are third-party reported, mostly from one competitor, and not independently verified.
- Full service: about $45,000/month, with one October 2026 snippet citing $50,000 or more.
- CMO coaching: around $6,500/month, depending on coach seniority.
- Scoped project work: $15,000+/month, attributed to an unnamed productized-services directory.
- Kalungi OKR tool, a separate product: Basic is $30/month billed annually, or $35/month billed monthly, with 5 active OKR sets.
A competitor reports that paid media, martech subscriptions, extra personnel and major launch PR are outside the retainer. A performance-linked component can also raise total spend. Total cost is likely well above the retainer figure.
Strengths
Kalungi Pros
- The tiering by ARR stage (T2D3, Syntropy, Full Service) makes it clear which engagement fits a given company.
- One retainer covers fractional CMO leadership and execution across content, paid media, ABM and HubSpot work.
- The homepage names many clients and quantified results, such as DataGuard's claimed 330% MQL growth and $4M pipeline in under six months.
Trade-offs
Kalungi Cons
- Kalungi's main weakness as a B2B SaaS marketing agency is unverified proof: every case study number is vendor-sourced, and we found no independent verification.
- No G2 count or score, no Clutch profile and no independent practitioner review were found. A competitor reports that G2 has too few reviews to be useful.
- No price comes from Kalungi, and reported figures start at a level that excludes many early-stage SaaS company budgets.
- The 2026 CEO change adds some uncertainty about continuity for the marketing team. That is a competitor's opinion, though the change itself is vendor-confirmed.
- No AI usage or disclosure was found, which limits fit for readers shopping for AI marketing services.

Bottom line
Kalungi Verdict
Kalungi offers a clearly structured, stage-based B2B SaaS marketing retainer with named clients and quantified results, but all of that proof is self-reported and no price is public. It is a plausible fit for funded SaaS teams that want a fractional CMO and an execution team in one contract, and a poor fit for seed-stage budgets or anyone seeking AI search work. Ask for client references you can call and a written scope that itemizes media, tooling and PR before signing, given the thin public documentation found in this research.
