What Casa Sisu does
Casa Sisu is a full-service residential interior design studio headquartered in Austin, Texas, founded in 2023 by Becca Frasier, an 11th-generation Texan who transitioned from a career in marketing, technology, and consulting after remodeling her own home. The firm serves homeowners undertaking remodels and new builds, offering three core service lines: Interior Design (space planning, material selection, and project management), Drafting & Technical Design (2D and 3D documents for permitting), and Construction Concierge (liaison services with general contractors including check-ins and inspections). Projects range in scope from small bathroom remodels to multi-million-dollar new builds, with a design philosophy the firm summarizes as 'not too little, not too much.'
The studio operates a sales-led, referral-driven go-to-market motion. Lead generation relies on a Squarespace portfolio website, an Instagram presence (@casasisuatx), three 2025 NARI Remodeling Awards (Entire House, Residential Bath Over $40K, Residential Bath Under $40K), and word-of-mouth from a network of Austin-area builder and architect partners (Simply Home, McCollum Homes, Skelly Build, and architect Thad Decker). Free virtual consultations are offered as the entry point. Pricing is custom quote-based professional services fees; no pricing tiers or figures are publicly disclosed. Collaborative consultant and interior designer Ashley Hunte, who holds a BFA from a CIDA-accredited program and brings experience from luxury residential firms in Boston and New York, works with Casa Sisu remotely from New York City.
Casa Sisu is privately held, founder-owned, and bootstrapped with no disclosed external investors, funding rounds, or parent company. Headcount is in the 1-10 band (two named principals plus additional designers). Operating footprint is concentrated in Austin, Texas, although the firm is open to projects in other locations. No AI/ML, platform, or SaaS technology components are evident; the offering is fundamentally a craft professional services business with light technical documentation workflows.

Casa Sisu competitors and assessment
Company assessmentDirect peers
- Studio McGee: Residential interior design studio founded in Salt Lake City with a national footprint; offers the same full-service design + project oversight model for home remodels and new builds, and demonstrates the scale Casa Sisu could reach with similar brand-building.
- Marie Flanigan Interiors: Boutique residential interior design firm based in Houston, TX serving high-end remodels and new builds across Texas; comparable Texas-market boutique studio competing for the same homeowner segment as Casa Sisu.
Emerging players
- Modsy: Online interior design service that pairs homeowners with designers for room-by-room 3D-rendered designs; serves a similar residential remodeling customer but through a virtual, lower-touch model rather than Casa Sisu's hands-on local concierge approach.
- Havenly: Online interior design platform connecting homeowners with professional designers for room redesigns; competes for the same residential remodeling customer base as Casa Sisu but at a lower price point and with a virtual delivery model.
- Decorilla: Online interior design marketplace offering multiple designer concepts per project; comparable in addressing the homeowner-remodel use case but via a virtual, multi-designer bidding model rather than Casa Sisu's single-studio relationship.
Others
- Sweeten: Online marketplace that matches homeowners with vetted general contractors for renovations, including remodels; addresses the same homeowner-remodel lifecycle as Casa Sisu but on the contractor-procurement side rather than the design side, making it an adjacent ecosystem player.
Broad incumbents
- West Elm Interior Design Services: Retailer's in-house interior design service offering room-by-room design packages to customers nationwide; addresses the same residential design need at a more accessible price point as part of a much larger home furnishings portfolio.
- CB2 Design Services: Retailer-branded interior design services offering room packages to homeowners; competes for the same residential customer as part of a broader home furnishings business rather than as a dedicated local studio like Casa Sisu.
