Your clients are asking for AI search, assistants and automation. Hiring AI engineers is slow and expensive, and turning the work down sends clients to someone else. We give you a senior team you can sell under your own name, starting this month.
What we build for your clients
AI search and assistants
Search across a client's documents, answer questions from their own data, and generate reports and presentations automatically.
Workflow automation
Replace slow, manual steps in content, review and approval workflows.
Flutter apps
One codebase for iOS and Android, with AI features built in.
Project or dedicated team
A fixed scope and price for one client build, or engineers working in your process, your tools and your brand, month to month.
Start small. Scale when it works.
Step 1: 20-minute call
Talk to the engineering lead who'd run your project. We sign an NDA first if you'd like.
Step 2: Paid pilot, 2–4 weeks
We deliver one real piece of a client project, under your brand.
Step 3: Ongoing partnership
Project by project or a dedicated team, growing with your pipeline.

Small, senior, AI-first
Director of Engineering
15+ years building products from early-stage MVPs to systems used by millions. Former CTO; scaled Paytm's chat platform to 3 million users. Leads engineering at Synthlane.
We're a small, AI-first engineering team led by senior engineers who've built at Meta and Paytm, and for global companies in pharma and gaming. Every project has a senior engineering lead who runs your calls and delivery. You talk to the people building your project, not account managers.

Our engineers have shipped AI that teams at large companies use every day.
With guardrails
Access control, audit trails and review steps built in from day one.

Questions agencies ask
Will my client know you're involved?
No. We work under your brand, with your email addresses and in your tools. Your client only ever sees your team.
Who owns the code?
You do. Full IP transfers to you on payment, and the repositories live in your accounts.
Can you join client calls?
Yes. Our engineers join as part of your team, under your company name, and can present technical work directly.
Who will I actually work with?
A senior engineering lead runs your project day to day: calls, scoping and delivery. Rahul leads engineering across all Synthlane projects. Execution is done by our engineers under the lead's direct review.
What if an engineer isn't the right fit?
Tell us and we replace them at no extra cost, with a proper handover so the project keeps moving.
How do you price?
A fixed price per project after a short scoping call, or a monthly rate per dedicated engineer. The pilot is a fixed, paid engagement.
What technology do you use?
Python and TypeScript, LangGraph and MCP for agents, Claude, GPT and open models, Flutter for mobile, on AWS, GCP or Azure. We fit your stack.
How does payment work?
Projects are billed by milestone. Dedicated teams are billed monthly in advance. We invoice in USD, GBP, EUR or INR.
