You can onboard a pre-vetted fintech development team in as little as a few days through a platform like Trio, with individual developers often starting within a week and larger team build-outs typically landing in the two to three week range. That speed comes from screening happening before you enter the process rather than during it.
The typical flow: you share your requirements around stack, compliance needs, and team structure, and Trio returns a shortlist of matched candidates. You interview, select, and move to contracting. Many developers in the pool actively want new engagements, so the lag between first conversation and day one tends to run much shorter than a traditional recruiting process.
A few things can stretch the timeline. Very niche tech stacks and slow internal decision-making both add time. Being clear upfront about what you actually need versus what would be nice to have appears to speed up matching more than anything else.
