What is the most affordable video advertising software for SMBs?

Hi, G2 community. Video ads can be powerful for smaller businesses, but affordability is always a sticking point. I'd like your help in figuring out what is the most affordable video advertising software for SMBs?

Here are a few platforms I’ve been looking into:

• StackAdapt (4.8/5 on G2) is a programmatic advertising platform that includes video ads across channels. But is its pricing flexible enough for SMB budgets?
• MNTN Performance TV (4.9/5 on G2) is built around connected TV ads with a performance-driven approach. Can smaller businesses run cost-effective campaigns here, or is it better suited for larger budgets?
• Vibe (4.8/5 on G2) positions itself as a solution for video and connected TV advertising. How accessible is it for SMBs looking for affordable entry points?
• Simpli.fi (4.5/5 on G2) offers programmatic and local targeting options, including video. Does it provide the right balance between cost and reach for SMBs?

For those of you working with smaller budgets:

• Which of these tools has delivered the best ROI for video advertising?
• Do SMBs get enough flexibility with minimum spend and targeting?
• Any hidden costs or challenges when starting out with these platforms?

Thanks in advance. I think these insights will help a lot of small teams figure out where video advertising makes sense.
