Building ViteFunnels: My Entrepreneurship Journey from Side Project to Agency

The story behind founding ViteFunnels - a digital solutions agency. Learn about the challenges, lessons, and insights from building a service business while working full-time.

ViteFunnels started as a weekend experiment and grew into a full-service digital solutions agency. The journey taught me more about business, clients, and myself than any book or course could. In this post, I’ll share the real story—the wins, the failures, and the lessons learned along the way.

The Beginning: Spotting a Gap

The Problem I Noticed

While working as a data engineer, I kept hearing the same frustrations from business owners:

“We have all this data, but we can’t make sense of it.” “Our marketing team uses five different tools that don’t talk to each other.” “We need someone who understands both the technical side and the business side.”

This wasn’t just one conversation—it was a pattern. Companies were drowning in tools (Google Analytics, HubSpot, Salesforce, custom databases) but starving for insights.

My Unique Position

I realized I had an unusual combination of skills:

Technical SkillsBusiness Understanding
Data pipelinesROI calculation
API integrationsMarketing funnels
Database designKPI tracking
Cloud infrastructureCustomer journey mapping

This intersection—technical depth + business acumen—was rare. And valuable.

  1. Data Integration: Connect disparate systems into unified dashboards

The Early Days: Challenges Faced

Challenge 1: Time Management

Problem: Balancing a full-time data engineering job with a growing side business.

What I tried:

  • Working evenings and weekends → Led to burnout
  • Saying yes to every project → Overcommitment
  • No boundaries between job and side business → Both suffered

What worked:

  • Dedicated “ViteFunnels days” (Saturdays)
  • Time-blocking: 6-8 AM for client calls before day job
  • Clear scope definition to avoid scope creep
  • Raising prices to work with fewer, better clients

Challenge 2: Client Acquisition

Problem: No track record, no referrals, no pipeline.

What didn’t work:

  • Cold emailing (1% response rate)
  • Upwork/Fiverr (race to the bottom on price)
  • Generic LinkedIn posts (“Excited to announce…”)

What worked:

  • Writing technical content (blog posts, case studies)
  • Niche positioning: “Data infrastructure for marketing teams”
  • Offering free audits (led to paid engagements)
  • Partnering with marketing agencies (they needed technical help)

Challenge 3: Building Trust Without a Portfolio

Problem: Clients want case studies, but I couldn’t share work from previous clients.

Solution:

  • Created detailed case studies with anonymized data
  • Built public tools (free calculators, templates)
  • Wrote transparently about processes and approaches
  • Offered pilot projects at reduced rates

Challenge 4: Cash Flow Management

Problem: Irregular income made financial planning difficult.

What I learned:

  • 50% upfront, 50% on delivery (standard for projects)
  • Retainer agreements for predictable income
  • 3-month expense reserve before taking on big projects
  • Clear payment terms with late fees (rarely enforced, but important to have)

Key Learnings from Building ViteFunnels

Learning 1: Start Small, Validate Quickly

Mistake: I initially wanted to build a full platform with dashboards, automation, everything.

Reality: Clients didn’t want a platform—they wanted specific problems solved.

Pivot: Started with small, well-defined projects:

  • “Set up conversion tracking for our Facebook ads”
  • “Build a dashboard showing our marketing ROI”
  • “Fix our broken Google Analytics setup”

These small wins built trust and led to larger engagements.

Learning 2: Word-of-Mouth is Powerful (But Slow)

The best clients came from referrals:

  • Client A refers Client B → Similar project, easier sale
  • Client B refers Client C → Different industry, new use case
  • Repeat cycle

But it takes time. I didn’t get my first referral until month 4.

Learning 3: Deliver Exceptional Value

This sounds obvious, but “value” is subjective. I learned to:

  • Over-communicate: Weekly updates, even if there’s no progress
  • Under-promise, over-deliver: Pad timelines, deliver early
  • Document everything: Clients love clear documentation
  • Be proactive: “I noticed X, you might want to consider Y”

Learning 4: Build Long-Term Relationships

A one-time project is okay. A retainer is better. A partnership is best.

Project → Retainer → Partnership pipeline:

Initial Project (4-6 weeks)

Client sees value, trusts expertise

Monthly Retainer (ongoing support, improvements)

Quarterly Strategy Sessions

Trusted Advisor Role (involved in major decisions)

The Numbers: Revenue and Growth

Here’s my journey (revenue is monthly recurring + project work):

MonthRevenueClientsKey Event
1-3$0-2K0-1First client (referral)
4-6$2-5K1-3Second client, first retainer
7-9$5-10K3-5Quit freelance platforms
10-12$10-20K5-8First hire (contractor)
13-18$20-40K8-12Full-time on ViteFunnels

Note: This isn’t linear. Some months were terrible. One client leaving could drop revenue by 30%.

Advice for Aspiring Entrepreneurs

1. Don’t Quit Your Day Job (Yet)

Start as a side project. Validate that:

  • People will pay for your service
  • You can deliver consistently
  • The market is large enough

Only go full-time when:

  • Side income is 50%+ of your salary
  • You have 6+ months of expenses saved
  • You have a pipeline of committed clients

2. Find Your Niche

“Data engineer for hire” is too broad. “Data infrastructure for e-commerce marketing teams” is specific.

Specificity helps with:

  • Marketing message
  • Pricing (specialists charge more)
  • Referrals (people know who to recommend)

3. Build in Public (Selectively)

I started writing about my approach:

  • Technical deep-dives
  • Case studies (anonymized)
  • Process documentation

This established credibility and attracted clients who already understood my value.

4. Know When to Say No

I said yes to everything early on. Mistake.

Red flags:

  • “This is a great opportunity for exposure”
  • Unwillingness to sign a contract
  • Budget discussions focused only on price
  • Disrespect for your time (late-night calls, constant scope changes)

Green flags:

  • Clear about goals and constraints
  • Values expertise, not just execution
  • Responsive and communicative
  • Sees you as a partner, not a vendor

Where ViteFunnels Is Headed

Current focus areas:

  1. Productized Services: Turning custom work into repeatable offerings
  2. Team Building: Hiring specialists who complement my skills
  3. Thought Leadership: More content, speaking, community building
  4. Strategic Partnerships: Working with agencies and consultancies

The goal isn’t to build the biggest agency—it’s to build the right agency for the clients we serve best.

Key Takeaways

Building ViteFunnels taught me:

  1. Problems worth solving exist everywhere: Look for frustration, inefficiency, manual work
  2. Unique combinations are valuable: My robotics background + data engineering + business understanding = rare skillset
  3. Trust is earned through delivery: Marketing gets attention, results get referrals
  4. Patience compounds: Small, consistent efforts build momentum over time
  5. ** entrepreneurship is a skill**: It’s learned through practice, not just theory

The journey continues. If you’re considering starting something, my advice: start small, stay consistent, and focus on delivering genuine value.
