A signature brand. A strategic advisory.
MGA.Expert is a boutique advisory specialized in designing, implementing and running strategic partnership programs, combining consulting authority with the personal signature of its founder.
To turn connections into concrete growth opportunities through strategic relationships, execution and collaboration.
To help companies build and run partnership programs with clear goals, processes, owners and KPIs.
To be a reference in Partnerships as a Service, professionalizing alliance development for companies that don't yet have a structured internal team.


“More than recommending partnerships, we take responsibility for developing them.”
MGA.Expert is a consultancy founded and led by Mariane Siqueira, a specialist in Strategic Partnerships and Business Development.
Our experience was built in practice, working directly on structuring, leading and developing partnerships for companies and organizations across different markets.
That experience gave rise to our Partnerships as a Service model: methodology, specialized professionals and continuous execution for companies that want to develop strategic partnerships.
