Duty Ventures - Software Design and Engineering Company

I'm leading a software development agency focused on fast iterations. Most of our clients are shipping more features, responding faster to support tickets, and have accelerated growth because of us.

We focused on HealthCare a lot lately due to the accelerated digitalization in this industry. I am a strong believer that we can make healthcare more technically advanced via pure software. 

In terms of technologies, our previous projects involved Ruby on Rails, React, React Native, Scala, Java, Kubernetes, GCP, AWS (ECS, RDS, AKS), Stripe Connect, HIPAA compliance.

Some of our previous clients: 
- Spotify
- Colgate
- Go4Ellis (incl. HIPAA compliance)
- KindBody (+1 HIPAA)
- NXT Sports
- Noom (Healthcare)
- Mochila Fulfillment
- 3Step
- Mylk Guys (YCombinator)
- NLV Productions
- SH Technologies
- One Step Software (Techstars)
- Ergodic Labs
- Med Prep
- Testing Psych
- Abundance Digital

Transforming Visions into AI MVPs & Products | Founder @Duty Ventures | Ex {Google, Apple and Amazon}

Hi, I’m Cosmin, the Founder and Lead Engineer of Duty Ventures. 

After some experience as a software developer in companies such as Google, Apple, and Amazon, I decided to launch my project.

With several former colleagues and college friends, we launched our own startup specializing in software development for entrepreneurs and customers needing software development services. 

Duty Ventures is all about developing software products from start to finish, thanks to the experiences we have all acquired in the past years.

One of our most successful services is aimed at entrepreneurs and early-stage founders, for whom we provide an MVP-builder service getting their product from 0 to 1 within weeks!

However, our services are not limited to that. The teams we create do much more than just create MVPs and are able to adapt to the different technologies requested, all of this in an agile way.

Our most recurrent services are the following:
- MVP creation
- Custom Software Development
- Blockchain Development
- Mobile Development
- Checkout pages
- E-Commerce

And our most used technologies are:
- Ruby on Rails
- React
- React Native
- Java
- NodeJS

Engineering Teams for Ambitious Founders | Founder @Duty Ventures | Ex {Google, Apple and Amazon}

Perhaps my biggest lesson from working more than 5 years providing Software Development Services is: don’t burn bridges. It’s hard to do it. At some point, you might not deliver as well as you used to. There are peaks, and they are valleys. We need to be able to cross both, since we only have a North Star. What’s important is the process, not the outcome. If you focus on the process, the right outcomes will naturally come.

Now back to my idea: no matter what happens with a relationship, it’s best to end it on good terms. Make sure both sides are happy after moving in completely different directions. Why? Because really, that leaves the door open for future opportunities. This happened to me! Not once, not twice, but many times. Your current project might end, but the founder will have another side project they want to pursue, or they will move to a high-growth startup that could use your expertise.

It’s easier and better to invest in current and previous relationships than to build new ones. But one needs to do both for the best outcomes.

Remote work sounds simple. Hire from anywhere. Get talent everywhere.

But here’s what nobody tells you - compliance is a minefield.

Every country has its own labor laws, tax codes, regulations. What’s fine in the US might get you flagged in Germany or India.

I’ve worked with startups scaling global teams and seen founders blindsided by fines, audits, or even payroll freezes. Usually because they tried to copy-paste a US process onto the world.

Here’s what I tell anyone building a remote team:
- Never assume the rules are the same. Research each country before you hire.
- Don’t rely on guesswork. Use proper global payroll and compliance platforms.
- If you’re unsure, talk to a local expert. A quick check can save you months of trouble.
- Pay attention to IP and confidentiality laws. These differences can bite you later.

Bottom line: remote work makes geography irrelevant for talent, but not for compliance.

Get this wrong, and small mistakes become big distractions. Get it right, and your team can focus on what matters.

Ran into compliance surprises building your team? I’d love to hear what happened and what you learned.

5 worst discovery questions:

5 difficult scenarios for salespeople:
(Even for the top ones.)

5 difficult scenarios for salespeople:

Stop trying to fake urgency in B2B. 
(it doesn't work)

𝗬𝗼𝘂 𝗰𝗮𝗻𝗻𝗼𝘁 𝗰𝗿𝗲𝗮𝘁𝗲 𝘂𝗿𝗴𝗲𝗻𝗰𝘆 𝘄𝗶𝘁𝗵𝗼𝘂𝘁:

→ Knowing pain
→ Understanding the impact of pain

𝗙𝗼𝗿 𝟮 𝗿𝗲𝗮𝘀𝗼𝗻𝘀:

1️⃣ Not every problem is worth solving

Trying to create an urgency won't work if they don't have something that is worth solving.

Nobody will buy a strong painkiller for a mild headache, even if it’s the last day of a 20% discount.

If the impact of the pain is close to zero, no urgency will stick.

2️⃣ A problem can have different solutions

Even if the pain is real, buyers still have options.

𝗧𝗵𝗲𝘆 𝗰𝗮𝗻:

•⁠ ⁠Build in-house
•⁠ ⁠Pick a cheaper workaround
•⁠ ⁠Wait until the budget frees up

Both a raincoat and an umbrella protect you from rain.

If you don’t show why your path is better, faster, or safer;

Urgency dies.

𝗧𝗟;𝗗𝗥

𝗧𝗼 𝗰𝗿𝗲𝗮𝘁𝗲 𝗿𝗲𝗮𝗹 𝘂𝗿𝗴𝗲𝗻𝗰𝘆:

-⁠ ⁠Find the pain that matters most
- ⁠Show the true cost of doing nothing
- ⁠Prove why solving it now beats later
- ⁠Position your solution as the safest path

Deals move when urgency is real. 

Not when it’s forced.

How do you create urgency without sounding pushy?

5 Unexpected Things in Sales
(hope they happen to you today)

5 Unexpected things in sales:

Contact data is out of control.
(for real)

Don't get me wrong.

I don't mind people pitching me.

I do it every day, too.

BUT

Every single week, some people:

- Add me to lists I never joined.
- Drop me into random waitlists.
- Email me again after I unsubscribe.
- Promise what no one can deliver.
- Sends emails written with poor prompts.
- Message me on WhatsApp out of nowhere.

I block them. They switch mailboxes.
I say, “I’m not a fit,” they keep texting.
I say it on the phone, they keep selling.

“I want to tell you about a promo…”
 “There’s a new offer…”

I don't want to click on report Spam.
I don't want to be rude.
I get it, we all try to make a living.

But this is not outreach.
This is not marketing.

This is SPAM.

Are some people ruining the industry?

Bad contact data can kill your business.
(real examples)

Your data provider is the most important part of your tech stack.
It is non-negotiable.

If your data is bad, you lose.
Simple as that.

𝗦𝘁𝗮𝗿𝘁𝘂𝗽 𝟭:
Picked the best provider, tested ICP coverage.
Checked accuracy and verified test emails.
Only had HubSpot + the data provider (not ideal).

𝗥𝗲𝘀𝘂𝗹𝘁𝘀:
Hit targets.
Scaled the team.
Added new tools later.

𝗦𝘁𝗮𝗿𝘁𝘂𝗽 𝟮:
Paid for expensive tool stacks for sequencing, etc.
Then, they selected the most cost effective data provider.

𝗥𝗲𝘀𝘂𝗹𝘁𝘀:
High bounce rates.
Burned mailboxes.
Low call connect rates.
The team missed targets.
The company started downsizing the sales team.

𝗠𝘆 𝘁𝗶𝗽𝘀:
1.  Build a sample list. Verify it.
2. Check coverage across your ICP + regions.
3. Choose tools that use waterfall enrichment.

If your data provider is wrong, nothing you do will work.
You cannot afford bad data.

How do you choose your contact data provider?
