From Agency Vendor to Product Partner: How the Best Clients Actually Work With Us
Stop Buying “Hours.” Start Buying “Velocity.”
When you hire a vendor, you are buying their time. You are the manager. You have to police their efficiency. When you hire a Product Partner, you are buying velocity—the speed at which your business validates hypotheses.
The Shift
- Vendor Mindset: “I need 3 developers for 3 months to build this feature list.”
- Partner Mindset: “I need to increase retention by 20% in Q3. Here is our budget. How do we get there?”
In the Partner model, we might tell you *not* to build the feature you requested because the data suggests it won’t move the needle. A vendor will never tell you that, because it reduces their billable hours.
Startup Studio vs. Agency: The Structural Difference
Understanding who you are hiring is critical.
The Agency (The Vendor)
- Business Model: Service Fee / Hourly Rate.
- Incentive: Maximum utilization. Keep the project going as long as possible without getting fired.
- Risk: Low. If the product fails, they still get paid.
The Startup Studio (The Partner)
- Business Model: Hybrid (Fee + Equity/Revenue Share) or Venture Building.
- Incentive: Exit value / Revenue growth.
- Risk: Shared. If the product fails, our equity is worthless.
This structural alignment changes everything. It means when we see a security flaw or a UX dead-end, we fix it—not because it’s in the contract, but because it protects *our* investment too.
Transparency: Give Us the “Why,” Not Just the “What”
The biggest mistake founders make is treating their external team like mushroom farmers: keeping them in the dark and feeding them manure.
Successful clients open the books.
- “We have 6 months of runway.”
- “Our CAC (Customer Acquisition Cost) is too high.”
- “Invest needs to see $10k MRR by June.”
When we know the constraints, we can engineer around them. We might suggest a no-code MVP to save 3 months of dev time. We might suggest cutting a “nice-to-have” animation to double down on site speed. If you only give us a Jira ticket, we can only give you code. If you give us context, we can give you strategy.
The “No” Policy
A vendor says “Yes” to everything. “Can we add AI?” Yes. “Can we change the color scheme mid-sprint?” Yes. “Can we support IE11?” Yes.
A Partner says “No.” “No, AI adds complexity we don’t need for MVP.” “No, changing the design now delays launch by 2 weeks.”
Our best clients trust our “No” more than our “Yes.” They understand that every “No” is a decision to protect the timeline, the budget, and the core value proposition.
Integration: We Are Not “Over There”
Vendors live in their own Slack. They have a weekly status call. They feel “other.” Partners live in your Slack. We attend your All-Hands. We argue with your Head of Sales about lead qualification.
The Integration Checklist
- [ ] Shared Slack Channels: No silos.
- [ ] Direct Access: Developers talk to Founders, not just through PMs.
- [ ] Shared Roadmap: We work off the same Master Roadmap, not a separate “Outsourced” list.
How to Hire a Product Partner
If you are ready to stop managing vendors and start building with partners, the interview process needs to change.
Don’t Ask:
- “What is your hourly rate?”
- “Can you send me a quote for these 50 features?”
Do Ask:
- “Here is my business goal. How would you solve it?”
- “Tell me about a time you told a client they were wrong.”
- “How do you handle technical debt?” (See our thoughts on Cheap Dev Costs)
Conclusion: The Choice is Yours
You can rent hands, or you can recruit minds. Hands are cheaper in the short run. Minds are cheaper in the long run.
If you are building a commodity, hire a vendor. If you are building a company, hire a Startup Studio.
Frequently Asked Questions
Does a Product Partner cost more than a Vendor?
On an hourly basis? Usually yes. On a “Cost Per Successful Outcome” basis? We are significantly cheaper. A vendor might charge $50/hr but take 1,000 hours to build the wrong thing ($50k waste). We might charge $150/hr but build the *right* thing in 200 hours ($30k success).
Do you take equity?
We operate on a flexible model. For select high-potential startups, we offer “Venture Services” where a portion of our fee is swapped for equity, ensuring total alignment.
Can I transition from Vendor to Partner with my current agency?
It’s difficult. The “Vendor” DNA is hard to rewrite. If their business model relies on maximizing billable hours, asking them to be efficient is asking them to lower their revenue.
What if I already have an in-house CTO?
Great. We work alongside CTOs as their “Special Forces” team. The CTO sets the vision; we provide the execution velocity and specialized skills (AI, Blockchain, Growth) that they might not have in-house.
Is We Are Presta an Agency or a Studio?
We are a Startup Studio. We build our own products, and we start products for others. We have skin in the game.
