From Agency to Product: Turning Services into SaaS on Purpose
Belkins started as a pure service business. Over time, we realized some of our hardest, most annoying problems were actually products in disguise. That’s how things like deliverability tooling and, later, AI‑assisted workflows were born. I’ve come to believe agencies are one of the best ways to incubate SaaS—if you know what you’re looking for.

From Agency to Product: Turning Services into SaaS on Purpose
Agencies are underrated SaaS incubators. Belkins taught me that almost every painful, repeatable service hides a product. The trick is productizing on purpose.
1. Why agencies are perfect SaaS laboratories
In an agency:
You touch many similar customers
You see the same problems over and over
You feel operational pain before the market does
That’s gold.
Instead of guessing what to build, you’re getting punched in the face with real constraints every day.
2. Signals a service should become a product
The patterns I watch for:
Repetition: same workflow across many clients
Pain: team complains about it constantly
Value: solving it unlocks obvious, measurable ROI for clients
Defensibility: it relies on data, process, or expertise that isn’t trivial to copy
If something hits all four, I stop and ask, “Are we accidentally sitting on a product?”
3. The productization path: from internal tool to SaaS
I like a staged path:
Internal tool
Build the minimum system that makes your team’s life easier.
No login, no billing—just usefulness.
Packaged service
Wrap that tool in a clearer offer.
Sell it as “X” with a fixed price and outcome.
External product
Add self‑serve UX, onboarding, documentation.
Start selling it outside your agency base.
The mistake is trying to jump straight to step 3.
4. Avoiding cannibalization and internal war
When you productize inside an agency, people get nervous:
“Will this kill our services?”
“Who owns revenue now?”
My rules:
Be explicit: the product exists to augment services, not replace them (at least early).
Create separate P&Ls as soon as possible.
Give someone clear ownership of the product with permission to say “no” to custom work.
Services are your distribution. Product is your leverage. Don’t turn them into enemies.
5. Org design: who does what
At first, the product team is tiny:
1 founder / PM hybrid
1–2 engineers
1 designer or UX‑minded dev
The agency team:
Feeds insights and bugs into a shared backlog
Gets priority on fixes, because they’re paying with real pain
Becomes your first “customer advisory board” whether they like it or not
Over time, I split:
Separate standups
Separate roadmaps
Shared goals around revenue and retention
6. Founder questions before you spin up “yet another product”
Before you decide to “build SaaS from our agency,” ask:
Are we solving a problem we deeply understand?
Would at least 5–10 of our existing clients pay for this separately?
Can I see a world where this has its own brand and website?
Do we have one person who will wake up owning product success?
Can we afford 12–18 months of investment before it becomes self-sustaining?
The more “yes” you get, the less it’s a vanity product and the more it’s a real business.
I write more about this agency → product path in my newsletter and share ongoing experiments on LinkedIn, so if this resonates, that’s where I unpack the details over time.
